CYCLOSPORINE

Cyclosporine oral solution, USP MODIFIED is an oral formulation of cyclosporine, USP that immediately forms an emulsion in an aqueous environment. Cyclosporine, USP, the active principle in cyclosporine oral solution, USP MODIFIED, is a cyclic polypeptide immunosuppressant agent consisting of 11 amino acids. It is produced as a metabolite by the fungus species Tolypocladium inflatum . Chemically, cyclosporine, USP is designated as [ R -[ R *, R *-( E )]]-cyclic-(L-alanyl-D-alanyl- N -methyl-L-leucyl- N -methyl-L-leucyl- N -methyl-L-valyl-3-hydroxy- N ,4-dimethyl-L-2-amino-6-octenoyl-L-α-amino-butyryl- N -methylglycyl- N -methyl-L-leucyl-L-valyl- N -methyl-L-leucyl) and has the following structural formula: Each mL of cyclosporine oral solution, USP MODIFIED contains 100 mg/mL cyclosporine, USP and 15.3% v/v (12.18% wt/vol) dehydrated alcohol, USP and has the following inactive ingredients: polyoxyl 40 hydrogenated castor oil, polyglycerol (3) oleate and polyglycerol (10) oleate. Cyclosporine Chemical Structure

Kidney, Liver, and Heart Transplantation Cyclosporine oral solution, USP MODIFIED is indicated for the prophylaxis of organ rejection in kidney, liver, and heart allogeneic transplants. Cyclosporine oral solution, USP MODIFIED has been used in combination with azathioprine and corticosteroids. Rheumatoid Arthritis Cyclosporine oral solution, USP MODIFIED is indicated for the treatment of patients with severe active, rheumatoid arthritis where the disease has not adequately responded to methotrexate. Cyclosporine oral solution, USP MODIFIED can be used in combination with methotrexate in rheumatoid arthritis patients who do not respond adequately to methotrexate alone. Psoriasis Cyclosporine oral solution, USP MODIFIED is indicated for the treatment of adult, nonimmunocompromised patients with severe (i.e., extensive and/or disabling), recalcitrant, plaque psoriasis who have failed to respond to at least one systemic therapy (e.g., PUVA, retinoids, or methotrexate) or in patients for whom other systemic therapies are contraindicated, or cannot be tolerated. While rebound rarely occurs, most patients will experience relapse with cyclosporine oral solution, USP MODIFIED as with other therapies upon cessation of treatment.

Cyclosporine oral solution, USP MODIFIED has increased bioavailability in comparison to Sandimmune (cyclosporine oral solution, USP). Cyclosporine oral solution, USP MODIFIED and Sandimmune (cyclosporine oral solution, USP) are not bioequivalent and cannot be used interchangeably without physician supervision. The daily dose of cyclosporine oral solution, USP MODIFIED should always be given in two divided doses (BID). It is recommended that cyclosporine oral solution, USP MODIFIED be administered on a consistent schedule with regard to time of day and relation to meals. Grapefruit and grapefruit juice affect metabolism, increasing blood concentration of cyclosporine, thus should be avoided. Specific Populations Renal Impairment in Kidney, Liver, and Heart Transplantation Cyclosporine undergoes minimal renal elimination and its pharmacokinetics do not appear to be significantly altered in patients with end-stage renal disease who receive routine hemodialysis treatments (see CLINICAL PHARMACOLOGY ) . However, due to its nephrotoxic potential (see WARNINGS ) , careful monitoring of renal function is recommended; cyclosporine dosage should be reduced if indicated (see WARNINGS and PRECAUTIONS ) . Renal Impairment in Rheumatoid Arthritis and Psoriasis Patients with impaired renal function should not receive cyclosporine (see CONTRAINDICATIONS , WARNINGS and PRECAUTIONS ) . Hepatic Impairment The clearance of cyclosporine may be significantly reduced in severe liver disease patients (see CLINICAL PHARMACOLOGY ) . Dose reduction may be necessary in patients with severe liver impairment to maintain blood concentrations within the recommended target range (see WARNINGS and PRECAUTIONS ) . Newly Transplanted Patients The initial oral dose of cyclosporine oral solution, USP MODIFIED can be given 4 to 12 hours prior to transplantation or be given postoperatively. The initial dose of cyclosporine oral solution, USP MODIFIED varies depending on the transplanted organ and the other immunosuppressive agents included in the immunosuppressive protocol. In newly transplanted patients, the initial oral dose of cyclosporine oral solution, MODIFIED is the same as the initial oral dose of Sandimmune (cyclosporine oral solution, USP). Suggested initial doses are available from the results of a 1994 survey of the use of Sandimmune (cyclosporine oral solution, USP) in US transplant centers. The mean ± SD initial doses were 9 ± 3 mg/kg/day for renal transplant patients (75 centers), 8 ± 4 mg/kg/day for liver transplant patients (30 centers), and 7 ± 3 mg/kg/day for heart transplant patients (24 centers). Total daily doses were divided into two equal daily doses. The cyclosporine oral solution, USP MODIFIED dose is subsequently adjusted to achieve a pre-defined cyclosporine blood concentration (see Blood Concentration Monitoring in Transplant Patients, below) . If cyclosporine trough blood concentrations are used, the target range is the same for cyclosporine oral solution, USP MODIFIED as for Sandimmune (cyclosporine oral solution, USP). Using the same trough concentration target range for cyclosporine oral solution, USP MODIFIED as for Sandimmune (cyclosporine oral solution, USP) results in greater cyclosporine exposure when cyclosporine oral solution, USP MODIFIED is administered (see Pharmacokinetics, Absorption ) . Dosing should be titrated based on clinical assessments of rejection and tolerability. Lower cyclosporine oral solution, USP MODIFIED doses may be sufficient as maintenance therapy. Adjunct therapy with adrenal corticosteroids is recommended initially. Different tapering dosage schedules of prednisone appear to achieve similar results. A representative dosage schedule based on the patient’s weight started with 2.0 mg/kg/day for the first 4 days tapered to 1.0 mg/kg/day by 1 week, 0.6 mg/kg/day by 2 weeks, 0.3 mg/kg/day by 1 month, and 0.15 mg/kg/day by 2 months and thereafter as a maintenance dose. Steroid doses may be further tapered on an individualized basis depending on status of patient and function of graft. Adjustments in dosage of prednisone must be made according to the clinical situation. Conversion from Sandimmune (cyclosporine oral solution, USP) to cyclosporine oral solution, USP MODIFIED in Transplant Patients In transplanted patients who are considered for conversion to cyclosporine oral solution, USP MODIFIED from Sandimmune (cyclosporine oral solution, USP), cyclosporine oral solution, USP MODIFIED should be started with the same daily dose as was previously used with Sandimmune (cyclosporine oral solution, USP) (1:1 dose conversion). The cyclosporine oral solution, USP MODIFIED dose should subsequently be adjusted to attain the pre-conversion cyclosporine blood trough concentration. Using the same trough concentration target range for cyclosporine oral solution, USP MODIFIED as for Sandimmune (cyclosporine oral solution, USP) results in greater cyclosporine exposure when cyclosporine oral solution, USP MODIFIED is administered (see Pharmacokinetics, Absorption ) . Patients with suspected poor absorption of Sandimmune (cyclosporine oral solution, USP) require different dosing strategies (see Transplant Patients with Poor Absorption of Sandimmune (cyclosporine oral solution, USP), below) . In some patients, the increase in blood trough concentration is more pronounced and may be of clinical significance. Until the blood trough concentration attains the pre-conversion value, it is strongly recommended that the cyclosporine blood trough concentration be monitored every 4 to 7 days after conversion to cyclosporine oral solution, USP MODIFIED. In addition, clinical safety parameters, such as serum creatinine and blood pressure, should be monitored every two weeks during the first two months after conversion. If the blood trough concentrations are outside the desired range and/or if the clinical safety parameters worsen, the dosage of cyclosporine oral solution, USP MODIFIED must be adjusted accordingly. Transplant Patients with Poor Absorption of Sandimmune (cyclosporine oral solution, USP) Patients with lower than expected cyclosporine blood trough concentrations in relation to the oral dose of Sandimmune (cyclosporine oral solution, USP) may have poor or inconsistent absorption of cyclosporine from Sandimmune (cyclosporine oral solution, USP). After conversion to cyclosporine oral solution, USP MODIFIED, patients tend to have higher cyclosporine concentrations. Due to the increase in bioavailability of cyclosporine following conversion to Cyclosporine oral solution, USP MODIFIED, the cyclosporine blood trough concentration may exceed the target range. Particular caution should be exercised when converting patients to cyclosporine oral solution, USP MODIFIED at doses greater than 10 mg/kg/day. The dose of cyclosporine oral solution, USP MODIFIED should be titrated individually based on cyclosporine trough concentrations, tolerability, and clinical response. In this population the cyclosporine blood trough concentration should be measured more frequently, at least twice a week (daily, if initial dose exceeds 10 mg/kg/day) until the concentration stabilizes within the desired range. Rheumatoid Arthritis The initial dose of cyclosporine oral solution, USP MODIFIED is 2.5 mg/kg/day, taken twice daily as a divided (BID) oral dose. Salicylates, NSAIDs, and oral corticosteroids may be continued (see WARNINGS and PRECAUTIONS , Drug Interactions) . Onset of action generally occurs between 4 and 8 weeks. If insufficient clinical benefit is seen and tolerability is good (including serum creatinine less than 30% above baseline), the dose may be increased by 0.5 to 0.75 mg/kg/day after 8 weeks and again after 12 weeks to a maximum of 4 mg/kg/day. If no benefit is seen by 16 weeks of therapy, cyclosporine oral solution, USP MODIFIED therapy should be discontinued. Dose decreases by 25% to 50% should be made at any time to control adverse events, e.g., hypertension elevations in serum creatinine (30% above patient’s pretreatment level) or clinically significant laboratory abnormalities (see WARNINGS and PRECAUTIONS ) . If dose reduction is not effective in controlling abnormalities or if the adverse event or abnormality is severe, cyclosporine oral solution, USP MODIFIED should be discontinued. The same initial dose and dosage range should be used if cyclosporine oral solution, USP MODIFIED is combined with the recommended dose of methotrexate. Most patients can be treated with cyclosporine oral solution, USP MODIFIED doses of 3 mg/kg/day or below when combined with methotrexate doses of up to 15 mg/week (see CLINICAL PHARMACOLOGY , Clinical Trials) . There is limited long-term treatment data. Recurrence of rheumatoid arthritis disease activity is generally apparent within 4 weeks after stopping cyclosporine. Psoriasis The initial dose of cyclosporine oral solution, USP MODIFIED should be 2.5 mg/kg/day. Cyclosporine oral solution, USP MODIFIED should be taken twice daily, as a divided (1.25 mg/kg BID) oral dose. Patients should be kept at that dose for at least 4 weeks, barring adverse events. If significant clinical improvement has not occurred in patients by that time, the patient’s dosage should be increased at 2-week intervals. Based on patient response, dose increases of approximately 0.5 mg/kg/day should be made to a maximum of 4.0 mg/kg/day. Dose decreases by 25% to 50% should be made at any time to control adverse events, e.g., hypertension, elevations in serum creatinine (≥ 25% above the patient’s pretreatment level), or clinically significant laboratory abnormalities. If dose reduction is not effective in controlling abnormalities, or if the adverse event or abnormality is severe, cyclosporine oral solution, USP MODIFIED should be discontinued (see Special Monitoring for Psoriasis Patients ) . Patients generally show some improvement in the clinical manifestations of psoriasis in 2 weeks. Satisfactory control and stabilization of the disease may take 12 to 16 weeks to achieve. Results of a dose-titration clinical trial with cyclosporine oral solution, USP MODIFIED indicate that an improvement of psoriasis by 75% or more (based on PASI) was achieved in 51% of the patients after 8 weeks and in 79% of the patients after 16 weeks. Treatment should be discontinued if satisfactory response cannot be achieved after 6 weeks at 4 mg/kg/day or the patient’s maximum tolerated dose. Once a patient is adequately controlled and appears stable the dose of cyclosporine oral solution, USP MODIFIED should be lowered, and the patient treated with the lowest dose that maintains an adequate response (this should not necessarily be total clearing of the patient). In clinical trials, cyclosporine doses at the lower end of the recommended dosage range were effective in maintaining a satisfactory response in 60% of the patients. Doses below 2.5 mg/kg/day may also be equally effective. Upon stopping treatment with cyclosporine, relapse will occur in approximately 6 weeks (50% of the patients) to 16 weeks (75% of the patients). In the majority of patients rebound does not occur after cessation of treatment with cyclosporine. Thirteen cases of transformation of chronic plaque psoriasis to more severe forms of psoriasis have been reported. There were 9 cases of pustular and 4 cases of erythrodermic psoriasis. Long term experience with cyclosporine oral solution, USP MODIFIED in psoriasis patients is limited and continuous treatment for extended periods greater than one year is not recommended. Alternation with other forms of treatment should be considered in the long term management of patients with this life long disease. Recommendations for Administration To make cyclosporine oral solution, USP MODIFIED more palatable, it should be diluted with orange or apple juice that is at room temperature. Patients should avoid switching diluents frequently. This solution, when mixed with juice, may appear cloudy. Grapefruit juice affects metabolism of cyclosporine and should be avoided. The combination of cyclosporine oral solution, USP MODIFIED solution with milk can be unpalatable. The effect of milk on the bioavailability of cyclosporine when administered as cyclosporine oral solution, USP MODIFIED has not been evaluated. Take the prescribed amount of cyclosporine oral solution, USP MODIFIED from the container using the dosing syringe supplied, after removal of the protective cover, and transfer the solution to a glass of orange or apple juice. Stir well and drink at once. Do not allow diluted oral solution to stand before drinking. Use a glass container (not plastic). Rinse the glass with more diluent to ensure that the total dose is consumed. After use, dry the outside of the dosing syringe with a clean towel and replace the protective cover. Do not rinse the dosing syringe with water or other cleaning agents. If the syringe requires cleaning, it must be completely dry before resuming use. Blood Concentration Monitoring in Transplant Patients Transplant centers have found blood concentration monitoring of cyclosporine to be an essential component of patient management. Of importance to blood concentration analysis are the type of assay used, the transplanted organ, and other immunosuppressant agents being administered. While no fixed relationship has been established, blood concentration monitoring may assist in the clinical evaluation of rejection and toxicity, dose adjustments, and the assessment of compliance. Various assays have been used to measure blood concentrations of cyclosporine. Older studies using a nonspecific assay often cited concentrations that were roughly twice those of the specific assays. Therefore, comparison between concentrations in the published literature and an individual patient concentration using current assays must be made with detailed knowledge of the assay methods employed. Current assay results are also not interchangeable and their use should be guided by their approved labeling. A discussion of the different assay methods is contained in Annals of Clinical Biochemistry 1994; 31: 420-446. While several assays and assay matrices are available, there is a consensus that parent-compound-specific assays correlate best with clinical events. Of these, HPLC is the standard reference, but the monoclonal antibody RIAs and the monoclonal antibody FPIA offer sensitivity, reproducibility, and convenience. Most clinicians base their monitoring on trough cyclosporine concentrations. Applied Pharmacokinetics, Principles of Therapeutic Drug Monitoring (1992) contains a broad discussion of cyclosporine pharmacokinetics and drug monitoring techniques. Blood concentration monitoring is not a replacement for renal function monitoring or tissue biopsies.

General Cyclosporine oral solution, USP MODIFIED is contraindicated in patients with a hypersensitivity to cyclosporine or to any of the ingredients of the formulation. Rheumatoid Arthritis Rheumatoid arthritis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive cyclosporine oral solution, USP MODIFIED. Psoriasis Psoriasis patients who are treated with cyclosporine oral solution, USP MODIFIED should not receive concomitant PUVA or UVB therapy, methotrexate or other immunosuppressive agents, coal tar or radiation therapy. Psoriasis patients with abnormal renal function, uncontrolled hypertension, or malignancies should not receive cyclosporine oral solution, USP MODIFIED.

Kidney, Liver, and Heart Transplantation The principal adverse reactions of cyclosporine therapy are renal dysfunction, tremor, hirsutism, hypertension, and gum hyperplasia. Hypertension Hypertension, which is usually mild to moderate, may occur in approximately 50% of patients following renal transplantation and in most cardiac transplant patients. Glomerular Capillary Thrombosis Glomerular capillary thrombosis has been found in patients treated with cyclosporine and may progress to graft failure. The pathologic changes resembled those seen in the hemolytic-uremic syndrome and included thrombosis of the renal microvasculature, with platelet-fibrin thrombi occluding glomerular capillaries and afferent arterioles, microangiopathic hemolytic anemia, thrombocytopenia, and decreased renal function. Similar findings have been observed when other immunosuppressives have been employed post-transplantation. Hypomagnesemia Hypomagnesemia has been reported in some, but not all, patients exhibiting convulsions while on cyclosporine therapy. Although magnesium-depletion studies in normal subjects suggest that hypomagnesemia is associated with neurologic disorders, multiple factors, including hypertension, high dose methylprednisolone, hypocholesterolemia, and nephrotoxicity associated with high plasma concentrations of cyclosporine appear to be related to the neurological manifestations of cyclosporine toxicity. Clinical Studies In controlled studies, the nature, severity, and incidence of the adverse events that were observed in 493 transplanted patients treated with cyclosporine oral solution, USP MODIFIED were comparable with those observed in 208 transplanted patients who received Sandimmune (cyclosporine oral solution, USP) in these same studies when the dosage of the two drugs was adjusted to achieve the same cyclosporine blood trough concentrations. Based on the historical experience with Sandimmune (cyclosporine oral solution, USP), the following reactions occurred in 3% or greater of 892 patients involved in clinical trials of kidney, heart, and liver transplants.

The following reactions occurred in 2% or less of cyclosporine-treated patients: allergic reactions, anemia, anorexia, confusion, conjunctivitis, edema, fever, brittle fingernails, gastritis, hearing loss, hiccups, hyperglycemia, migraine (cyclosporine oral solution, USP MODIFIED), muscle pain, peptic ulcer, thrombocytopenia, tinnitus. The following reactions occurred rarely: anxiety, chest pain, constipation, depression, hair breaking, hematuria, joint pain, lethargy, mouth sores, myocardial infarction, night sweats, pancreatitis, pruritus, swallowing difficulty, tingling, upper GI bleeding, visual disturbance, weakness, weight loss. Patients receiving immunosuppressive therapies, including cyclosporine and cyclosporine-containing regimens, are at increased risk of infections (viral, bacterial, fungal, parasitic). Both generalized and localized infections can occur. Pre-existing infections may also be aggravated. Fatal outcomes have been reported (see WARNINGS ) .

Postmarketing Experience, Kidney, Liver and Heart Transplantation Hepatotoxicity Cases of hepatotoxicity and liver injury, including cholestasis, jaundice, hepatitis and liver failure; serious and/or fatal outcomes have been reported (see WARNINGS , Hepatotoxicity) . Increased Risk of Infections Cases of JC virus-associated progressive multifocal leukoencephalopathy (PML), sometimes fatal; and polyoma virus-associated nephropathy (PVAN), especially BK virus resulting in graft loss have been reported (see WARNINGS , Polyoma Virus Infections) . Headache, including Migraine Cases of migraine have been reported. In some cases, patients have been unable to continue cyclosporine, however, the final decision on treatment discontinuation should be made by the treating physician following the careful assessment of benefits versus risks. Pain of Lower Extremities Isolated cases of pain of lower extremities have been reported in association with cyclosporine. Pain of lower extremities has also been noted as part of Calcineurin-Inhibitor Induced Pain Syndrome (CIPS) as described in the literature. Rheumatoid Arthritis The principal adverse reactions associated with the use of cyclosporine in rheumatoid arthritis are renal dysfunction (see WARNINGS ) , hypertension (see PRECAUTIONS ) , headache, gastrointestinal disturbances, and hirsutism/hypertrichosis. In rheumatoid arthritis patients treated in clinical trials within the recommended dose range, cyclosporine therapy was discontinued in 5.3% of the patients because of hypertension and in 7% of the patients because of increased creatinine. These changes are usually reversible with timely dose decrease or drug discontinuation. The frequency and severity of serum creatinine elevations increase with dose and duration of cyclosporine therapy. These elevations are likely to become more pronounced without dose reduction or discontinuation.

In psoriasis patients treated in US controlled clinical studies within the recommended dose range, cyclosporine therapy was discontinued in 1.0% of the patients because of hypertension and in 5.4% of the patients because of increased creatinine. In the majority of cases, these changes were reversible after dose reduction or discontinuation of cyclosporine. There has been one reported death associated with the use of cyclosporine in psoriasis. A 27-year-old male developed renal deterioration and was continued on cyclosporine. He had progressive renal failure leading to death. Frequency and severity of serum creatinine increases with dose and duration of cyclosporine therapy. These elevations are likely to become more pronounced and may result in irreversible renal damage without dose reduction or discontinuation.

Increases in uric acid may occur and attacks of gout have been rarely reported. A minor and dose related hyperbilirubinemia has been observed in the absence of hepatocellular damage. Cyclosporine therapy may be associated with a modest increase of serum triglycerides or cholesterol. Elevations of triglycerides (> 750 mg/dL) occur in about 15% of psoriasis patients; elevations of cholesterol (> 300 mg/dL) are observed in less than 3% of psoriasis patients. Generally these laboratory abnormalities are reversible upon dose reduction or discontinuation of cyclosporine. Postmarketing Experience, Psoriasis Cases of transformation to erythrodermic psoriasis or generalized pustular psoriasis upon either withdrawal or reduction of cyclosporine in patients with chronic plaque psoriasis have been reported.

A. Effect of Drugs and Other Agents on Cyclosporine Pharmacokinetics and/or Safety All of the individual drugs cited below are well substantiated to interact with cyclosporine. In addition, concomitant use of NSAIDs with cyclosporine, particularly in the setting of dehydration, may potentiate renal dysfunction. Caution should be exercised when using other drugs which are known to impair renal function (see WARNINGS , Nephrotoxicity) . Drugs That May Potentiate Renal Dysfunction Antibiotics Antineoplastics Antifungals Anti-inflammatory Drugs Gastrointestinal Agents Immunosuppressives Other Drugs ciprofloxacin melphalan amphotericin B azapropazon cimetidine tacrolimus fibric acid derivatives (e.g., bezafibrate, fenofibrate) gentamicin ketoconazole colchicine ranitidine methotrexate tobramycin diclofenac vancomycin naproxen trimethoprim with sulfamethoxazole sulindac During the concomitant use of a drug that may exhibit additive or synergistic renal impairment with cyclosporine, close monitoring of renal function (in particular serum creatinine) should be performed. If a significant impairment of renal function occurs, the dosage of the coadministered drug should be reduced or an alternative treatment considered. Cyclosporine is extensively metabolized by CYP 3A isoenzymes, in particular CYP3A4, and is a substrate of the multidrug efflux transporter P-glycoprotein. Various agents are known to either increase or decrease plasma or whole blood concentrations of cyclosporine usually by inhibition or induction of CYP3A4 or P-glycoprotein transporter or both. Compounds that decrease cyclosporine absorption, such as orlistat, should be avoided. Appropriate cyclosporine oral solution, USP MODIFIED dosage adjustment to achieve the desired cyclosporine concentrations is essential when drugs that significantly alter cyclosporine concentrations are used concomitantly (see Blood Concentration Monitoring ) . 1. Drugs That Increase Cyclosporine Concentrations Calcium Channel Blockers Antifungals Antibiotics Glucocorticoids Other Drugs diltiazem fluconazole azithromycin methylprednisolone allopurinol nicardipine itraconazole clarithromycin amiodarone verapamil ketoconazole erythromycin bromocriptine voriconazole quinupristin/dalfopristin colchicine danazol imatinib metoclopramide nefazodone oral contraceptives HIV Protease Inhibitors The HIV protease inhibitors (e.g., indinavir, nelfinavir, ritonavir, and saquinavir) are known to inhibit cytochrome P-450 3A and thus could potentially increase the concentrations of cyclosporine, however no formal studies of the interaction are available. Care should be exercised when these drugs are administered concomitantly. Grapefruit Juice Grapefruit and grapefruit juice affect metabolism, increasing blood concentrations of cyclosporine, thus should be avoided. 2. Drugs/Dietary Supplements That Decrease Cyclosporine Concentrations Antibiotics Anticonvulsants Other Drugs / Dietary Supplements nafcillin carbamazepine bosentan St. John’s Wort rifampin oxcarbazepine octreotide phenobarbital orlistat phenytoin sulfinpyrazone terbinafine ticlopidine Bosentan Coadministration of bosentan (250 to 1000 mg every 12 hours based on tolerability) and cyclosporine (300 mg every 12 hours for 2 days then dosing to achieve a C min of 200 to 250 ng/mL) for 7 days in healthy subjects resulted in decreases in the cyclosporine mean dose-normalized AUC, C max , and trough concentration of approximately 50%, 30%, and 60%, respectively, compared to when cyclosporine was given alone (see Effect of Cyclosporine on the Pharmacokinetics and/or Safety of Other Drugs or Agents ) . Coadministration of cyclosporine with bosentan should be avoided. Boceprevir Coadministration of boceprevir (800 mg three times daily for 7 days) and cyclosporine (100 mg single dose) in healthy subjects resulted in increases in the mean AUC and C max of cyclosporine approximately 2.7-fold and 2-fold, respectively, compared to when cyclosporine was given alone. Telaprevir Coadministration of telaprevir (750 mg every 8 hours for 11 days) with cyclosporine (10 mg on day 8) in healthy subjects resulted in increases in the mean dose-normalized AUC and C max of cyclosporine approximately 4.5-fold and 1.3-fold, respectively, compared to when cyclosporine (100 mg single dose) was given alone. St. John’s Wort There have been reports of a serious drug interaction between cyclosporine and the herbal dietary supplement St. John’s Wort. This interaction has been reported to produce a marked reduction in the blood concentrations of cyclosporine, resulting in subtherapeutic levels, rejection of transplanted organs, and graft loss. Rifabutin Rifabutin is known to increase the metabolism of other drugs metabolized by the cytochrome P-450 system. The interaction between rifabutin and cyclosporine has not been studied. Care should be exercised when these two drugs are administered concomitantly. B. Effect of Cyclosporine on the Pharmacokinetics and/or Safety of Other Drugs or Agents Cyclosporine is an inhibitor of CYP3A4 and of multiple drug efflux transporters (e.g., P-glycoprotein) and may increase plasma concentrations of comedications that are substrates of CYP3A4, P-glycoprotein or organic anion transporter proteins. Cyclosporine may reduce the clearance of digoxin, colchicine, prednisolone, HMG-CoA reductase inhibitors (statins), and, aliskiren, bosentan, dabigatran, repaglinide, NSAIDs, sirolimus, etoposide, and other drugs. See the full prescribing information of the other drug for further information and specific recommendations. The decision on coadministration of cyclosporine with other drugs or agents should be made by the healthcare provider following the careful assessment of benefits and risks. Digoxin Severe digitalis toxicity has been seen within days of starting cyclosporine in several patients taking digoxin. If digoxin is used concurrently with cyclosporine, serum digoxin concentrations should be monitored. Colchicine There are reports on the potential of cyclosporine to enhance the toxic effects of colchicine such as myopathy and neuropathy, especially in patients with renal dysfunction. Concomitant administration of cyclosporine and colchicine results in significant increases in colchicine plasma concentrations. If colchicine is used concurrently with cyclosporine, a reduction in the dosage of colchicine is recommended. HMG-CoA Reductase Inhibitors (Statins) Literature and postmarketing cases of myotoxicity, including muscle pain and weakness, myositis, and rhabdomyolysis, have been reported with concomitant administration of cyclosporine with lovastatin, simvastatin, atorvastatin, pravastatin, and, rarely fluvastatin. When concurrently administered with cyclosporine, the dosage of these statins should be reduced according to label recommendations. Statin therapy needs to be temporarily withheld or discontinued in patients with signs and symptoms of myopathy or those with risk factors predisposing to severe renal injury, including renal failure, secondary to rhabdomyolysis. Repaglinide Cyclosporine may increase the plasma concentrations of repaglinide and thereby increase the risk of hypoglycemia. In 12 healthy male subjects who received two doses of 100 mg cyclosporine capsule orally 12 hours apart with a single dose of 0.25 mg repaglinide tablet (one-half of a 0.5 mg tablet) orally 13 hours after the cyclosporine initial dose, the repaglinide mean C max and AUC were increased 1.8-fold (range: 0.6 to 3.7-fold) and 2.4-fold (range 1.2 to 5.3-fold), respectively. Close monitoring of blood glucose level is advisable for a patient taking cyclosporine and repaglinide concomitantly. Ambrisentan Coadministration of ambrisentan (5 mg daily) and cyclosporine (100 to 150 mg twice daily initially, then dosing to achieve C min 150 to 200 ng/mL) for 8 days in healthy subjects resulted in mean increases in ambrisentan AUC and C max of approximately 2-fold and 1.5-fold, respectively, compared to ambrisentan alone. When coadministering ambrisentan with cyclosporine, the ambrisentan dose should not be titrated to the recommended maximum daily dose. Anthracycline antibiotics High doses of cyclosporine (e.g., at starting intravenous dose of 16 mg/kg/day) may increase the exposure to anthracycline antibiotics (e.g., doxorubicin, mitoxantrone, daunorubicin) in cancer patients. Aliskiren Cyclosporine alters the pharmacokinetics of aliskiren, a substrate of P-glycoprotein and CYP3A4. In 14 healthy subjects who received concomitantly single doses of cyclosporine (200 mg) and reduced dose aliskiren (75 mg), the mean C max of aliskiren was increased by approximately 2.5-fold (90% CI: 1.96 to 3.17) and the mean AUC by approximately 4.3-fold (90% CI: 3.52 to 5.21), compared to when these subjects received aliskiren alone. The concomitant administration of aliskiren with cyclosporine prolonged the median aliskiren elimination half-life (26 hours versus 43 to 45 hours) and the T max (0.5 hours versus 1.5 to 2.0 hours). The mean AUC and C max of cyclosporine were comparable to reported literature values. Coadministration of cyclosporine and aliskiren in these subjects also resulted in an increase in the number and/or intensity of adverse events, mainly headache, hot flush, nausea, vomiting, and somnolence. The coadministration of cyclosporine with aliskiren is not recommended. Bosentan In healthy subjects, coadministration of bosentan and cyclosporine resulted in time-dependent mean increases in dose-normalized bosentan trough concentrations (i.e., approximately 21-fold on day 1 and 2-fold on day 8 (steady state)) compared to when bosentan was given alone as a single dose on day 1 (see Effect of Drugs and Other Agents on Cyclosporine Pharmacokinetics and/or Safety ) . Coadministration of cyclosporine with bosentan should be avoided. Dabigatran The effect of cyclosporine on dabigatran concentrations had not been formally studied. Concomitant administration of dabigatran and cyclosporine may result in increased plasma dabigatran concentrations due to the P-gp inhibitory activity of cyclosporine. Coadministration of cyclosporine with dabigatran should be avoided. Potassium-Sparing Diuretics Cyclosporine should not be used with potassium-sparing diuretics because hyperkalemia can occur. Caution is also required when cyclosporine is coadministered with potassium sparing drugs (e.g., angiotensin converting enzyme inhibitors, angiotensin II receptor antagonists), potassium-containing drugs as well as in patients on a potassium rich diet. Control of potassium levels in these situations is advisable. Nonsteroidal Anti-inflammatory Drug (NSAID) Interactions Clinical status and serum creatinine should be closely monitored when cyclosporine is used with NSAIDs in rheumatoid arthritis patients (see WARNINGS ) . Pharmacodynamic interactions have been reported to occur between cyclosporine and both naproxen and sulindac, in that concomitant use is associated with additive decreases in renal function, as determined by 99m Tc-diethylenetriaminepentaacetic acid (DTPA) and ( p -aminohippuric acid) PAH clearances. Although concomitant administration of diclofenac does not affect blood concentrations of cyclosporine, it has been associated with approximate doubling of diclofenac blood concentrations and occasional reports of reversible decreases in renal function. Consequently, the dose of diclofenac should be in the lower end of the therapeutic range. Methotrexate Interaction Preliminary data indicate that when methotrexate and cyclosporine were coadministered to rheumatoid arthritis patients (N = 20), methotrexate concentrations (AUCs) were increased approximately 30% and the concentrations (AUCs) of its metabolite, 7-hydroxy methotrexate, were decreased by approximately 80%. The clinical significance of this interaction is not known. Cyclosporine concentrations do not appear to have been altered (N = 6). Sirolimus Elevations in serum creatinine were observed in studies using sirolimus in combination with full-dose cyclosporine. This effect is often reversible with cyclosporine dose reduction. Simultaneous coadministration of cyclosporine significantly increases blood levels of sirolimus. To minimize increases in sirolimus concentrations, it is recommended that sirolimus be given 4 hours after cyclosporine administration. Nifedipine Frequent gingival hyperplasia when nifedipine is given concurrently with cyclosporine has been reported. The concomitant use of nifedipine should be avoided in patients in whom gingival hyperplasia develops as a side effect of cyclosporine. Methylprednisolone Convulsions when high dose methylprednisolone is given concurrently with cyclosporine have been reported. Other Immunosuppressive Drugs and Agents Psoriasis patients receiving other immunosuppressive agents or radiation therapy (including PUVA and UVB) should not receive concurrent cyclosporine because of the possibility of excessive immunosuppression. Interactions resulting in decrease of other drug levels Cyclosporine inhibits the enterohepatic circulation of mycophenolic acid (MPA). Concomitant administration of cyclosporine and mycophenolate mofetil or mycophenolate sodium in transplant patients may decrease the mean exposure of MPA by 20 to 50% when compared with other immunosuppressants, which could reduce efficacy of mycophenolate mofetil or mycophenolate sodium. Monitor patients for alterations in efficacy of mycophenolate mofetil or mycophenolate sodium, when they are coadministered with cyclosporine. C. Effect of Cyclosporine on the Efficacy of Live Vaccines During treatment with cyclosporine, vaccination may be less effective. The use of live vaccines should be avoided.
