Overview
Scopolamine transdermal system is designed for continuous release of scopolamine following application to an area of intact skin on the head, behind the ear. Each system contains 1.3 mg of scopolamine base. Scopolamine is (9-methyl-3-oxa-9-azatricyclo [3.3.1.0 2,4 ]nonan-7-yl) 3-hydroxy-2-phenylpropanoate. The empirical formula is C 17 H 21 NO 4 and its structural formula is: Scopolamine has a molecular weight of 303.35 and a pKa of 7.55 to 7.81. The scopolamine transdermal system is a circular, 0.28 mm thick, 2.5 cm 2 film with four layers. Proceeding from the visible surface towards the surface attached to the skin, these layers are: (1) a backing membrane of tan-colored, aluminized, polyester film; (2) a drug layer of scopolamine, light mineral oil, isopropyl palmitate, crospovidone, and polyisobutylene; (3) a microporous polypropylene membrane that controls the rate of delivery of scopolamine from the system to the skin surface; and (4) a contact layer formulation of mineral oil, polyisobutylene, isopropyl palmitate, crospovidone, and scopolamine. A release liner of siliconized polyester, which covers the adhesive layer, is removed before the system is used. Cross section of the system: Chemical Structure Image

( 1 ) post-operative nausea and vomiting (PONV) associated with recovery from anesthesia and/or opiate analgesia and surgery. ( 1 )
Dosage & Administration
Application and Removal ( 2.1 ): Each scopolamine transdermal system delivers 1 mg of scopolamine over 3 days. Only wear one transdermal system at a time. Do not cut the transdermal system. Wash hands thoroughly with soap and water after application. Avoid touching or applying pressure to the transdermal system once applied. Upon removal, fold used transdermal system in half with sticky side together, discard to prevent accidental contact or ingestion, and wash the hands and application site with soap and water. Recommended Dosage: Motion Sickness : Apply one transdermal system to the hairless area behind one ear at least 4 hours before antiemetic effect is required for use up to 3 days. If therapy for more than 3 days is required, remove the first transdermal system and apply a new transdermal system behind the other ear. ( 2.2 ) PONV : For surgeries other than cesarean section, apply one transdermal system behind the ear the evening before surgery and remove 24 hours following surgery. ( 2.2 ) 2.1 Important Application and Removal Instructions Each scopolamine transdermal system is formulated to deliver in vivo approximately 1 mg of scopolamine over 3 days. Only wear one transdermal system at any time. Do not cut the transdermal system. Apply the transdermal system to the skin in the postauricular area (hairless area behind one ear). After the transdermal system is applied on the dry skin behind the ear, wash hands thoroughly with soap and water and dry hands [see Warnings and Precautions (5.7) ] . If the transdermal system becomes displaced, discard the transdermal system, and apply a new transdermal system on the hairless area behind the other ear. Once the transdermal system has been affixed, avoid touching or applying pressure to the transdermal system while it is being worn, since pressure exerted on it may cause scopolamine to ooze out at the edge. Upon removal, fold the used transdermal system in half with the sticky side together, and discard in household trash in a manner that prevents accidental contact or ingestion by children, pets, or others. Wash the hands and application site with soap and water after transdermal system removal [see Warnings and Precautions (5.7) ]. 2.2 Recommended Adult Dosage Motion Sickness Apply one scopolamine transdermal system to the hairless area behind one ear at least 4 hours before the antiemetic effect is required – for use up to 3 days. If therapy is required for longer than 3 days, remove the first transdermal system and apply a new scopolamine transdermal system behind the other ear. PONV For surgeries other than cesarean section : Apply one scopolamine transdermal system the evening before scheduled surgery. Remove the transdermal system 24 hours following surgery.
Warnings & Precautions
Acute Angle Closure Glaucoma: Monitor for increased intraocular pressure in patients with open-angle glaucoma and adjust glaucoma therapy as needed. Discontinue if signs or symptoms of acute angle closure glaucoma develop. ( 5.1 ) Neuropsychiatric Adverse Reactions : May cause psychiatric and cognitive effects, seizures and impair mental and/or physical abilities. Monitor patients for new or worsening psychiatric symptoms during treatment and during concomitant treatment with other drugs that are associated with similar psychiatric effects. ( 5.2 , 7.1 ) Eclamptic Seizures in Pregnant Women : Avoid use in patients with severe preeclampsia. ( 5.3 ) Gastrointestinal and Urinary Disorders : Consider more frequent monitoring during treatment in patients suspected of having intestinal obstruction; patients with pyloric obstruction, patients with impeded urine flow, or receiving other anticholinergic drugs. Discontinue if patient develops difficulty in urination. ( 5.4 , 7.2 ) Hyperthermia : Serious adverse reactions have been reported postmarketing in adult and pediatric patients, including fatal cases. If symptoms occur, remove the transdermal system, and contact a healthcare provider. ( 5.5 ) Drug Withdrawal/Post-Removal Symptoms: Anticholinergic symptoms may occur 24 hours or more after removal of the transdermal system. ( 5.6 ) Blurred Vision : Avoid contact with the eyes. ( 2.1 , 5.7 ) Magnetic Resonance Imaging (MRI) Skin Burns : Remove scopolamine transdermal system prior to MRI scan. ( 5.8 ) 5.1 Acute Angle Closure Glaucoma The mydriatic effect of scopolamine may cause an increase in intraocular pressure resulting in acute angle closure glaucoma. Monitor intraocular pressure in patients with open angle glaucoma and adjust glaucoma therapy during scopolamine transdermal system use, as needed. Advise patients to immediately remove the transdermal system and contact their healthcare provider if they experience symptoms of acute angle closure glaucoma (e.g., eye pain or discomfort, blurred vision, visual halos or colored images in association with red eyes from conjunctival congestion and corneal edema). 5.2 Neuropsychiatric Adverse Reactions Psychiatric Adverse Reactions Scopolamine has been reported to exacerbate psychosis. Other psychiatric reactions have also been reported, including acute toxic psychosis, agitation, speech disorder, hallucinations, paranoia, and delusions [see Adverse Reactions (6.2) ] . Monitor patients for new or worsening psychiatric symptoms during treatment with scopolamine transdermal system. Also, monitor patients for new or worsening psychiatric symptoms during concomitant treatment with other drugs that are associated with similar psychiatric effects [see Drug Interactions (7.1) ] . In cases of psychiatric reactions occurring, scopolamine transdermal system should be removed at once. If, despite this, the symptoms persist in a severe form, instruct patients to seek medical attention. Seizures Seizures and seizure-like activity have been reported in patients receiving scopolamine. Weigh this potential risk against the benefits before prescribing scopolamine transdermal system to patients with a history of seizures, including those receiving anti-epileptic medication or who have risk factors that can lower the seizure threshold. Cognitive Adverse Reactions Scopolamine can cause drowsiness, disorientation, and confusion. Discontinue scopolamine transdermal system if signs or symptoms of cognitive impairment develop. If, despite this, the symptoms persist in a severe form, instruct patients to seek medical attention. Elderly and pediatric patients may be more sensitive to the neurological and psychiatric effects of scopolamine transdermal system. Consider more frequent monitoring during treatment with scopolamine transdermal system in elderly patients [see Use in Specific Populations (8.5) ] . Scopolamine transdermal system is not approved for use in pediatric patients [see Use in Specific Populations (8.4) ] . Hazardous Activities Scopolamine transdermal system may impair the mental and/or physical abilities required for the performance of hazardous tasks such as driving a motor vehicle, operating machinery, or participating in underwater sports. Concomitant use of other drugs that cause central nervous system (CNS) adverse reactions (e.g., alcohol, sedatives, hypnotics, opiates, and anxiolytics) or have anticholinergic properties (e.g., other belladonna alkaloids, sedating antihistamines, meclizine, tricyclic antidepressants, and muscle relaxants) may increase this effect [see Drug Interactions (7.1) ] . Inform patients not to operate motor vehicles or other dangerous machinery or participate in underwater sports until they are reasonably certain that scopolamine transdermal system does not affect them adversely. 5.3 Eclamptic Seizures in Pregnant Women Eclamptic seizures have been reported in pregnant women with severe preeclampsia soon after injection of intravenous and intramuscular scopolamine [see Use in Specific Populations (8.1) ] . Avoid use of scopolamine transdermal system in patients with severe preeclampsia. 5.4 Gastrointestinal and Urinary Disorders Scopolamine, due to its anticholinergic properties, can decrease gastrointestinal motility and cause urinary retention. Consider more frequent monitoring during treatment with scopolamine transdermal system in patients suspected of having intestinal obstruction, patients with pyloric obstruction or patients with impeded flow of urine (e.g., in diseases of the prostate or urinary bladder neck obstruction), and patients receiving other anticholinergic drugs [see Drug Interactions (7.2) ] . Discontinue scopolamine transdermal system in patients who develop difficulty in urination. 5.5 Hyperthermia Serious adverse reactions of hyperthermia have been reported postmarketing in adult and pediatric patients receiving transdermal scopolamine, including fatal cases. Anticholinergic agents, including scopolamine, can increase core body temperature and reduce sweating, which may cause further increases in body temperature. Hyperthermia may be exacerbated by exposure to external heat sources or high environmental temperature. Pediatric and geriatric patients may be more susceptible to these anticholinergic effects on thermoregulation. Advise patients if body temperature increases, or they are not sweating in warm environmental conditions, to remove the transdermal system and contact their healthcare provider. Symptoms may persist following removal of the used transdermal system as there may be continued systemic absorption of scopolamine through the skin. Scopolamine transdermal system is not approved for use in pediatric patients [see Use in Specific Populations (8.4 , 8.5) ] . 5.6 Drug Withdrawal/Post-Removal Symptoms Discontinuation of scopolamine transdermal system, usually after several days of use, may result in withdrawal symptoms, such as disturbances of equilibrium, dizziness, nausea, vomiting, abdominal cramps, sweating, headache, mental confusion, muscle weakness, bradycardia, and hypotension. The onset of these symptoms is generally 24 hours or more after the transdermal system has been removed. Instruct patients to seek medical attention if they experience severe symptoms. 5.7 Blurred Vision Scopolamine can cause temporary dilation of the pupils resulting in blurred vision if it comes in contact with the eyes. Advise patients to wash their hands thoroughly with soap and water and dry their hands immediately after handling the transdermal system, do not touch the system while wearing it, and wash hands and the application site with soap and water after transdermal system removal [see Dosage and Administration (2.1) ] . 5.8 Magnetic Resonance Imaging (MRI) Skin Burns Scopolamine transdermal system contains an aluminized membrane. Skin burns have been reported at the application site in patients wearing an aluminized transdermal system during an MRI scan. Remove scopolamine transdermal system before undergoing an MRI.

( 6.1 ) PONV (≥ 3%): dry mouth, dizziness, somnolence, agitation, visual impairment, confusion, mydriasis, and pharyngitis. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Rhodes Pharmaceuticals at 1-888-873-5329 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Motion Sickness The most common adverse reaction (approximately two thirds) was dry mouth. Less common adverse reactions included drowsiness (less than one sixth), blurred vision, and dilation of the pupils. PONV Common adverse reactions, occurring in at least 3% of patients in PONV clinical trials, are shown in Table 1. Table 1 Common Adverse Reactions occurring in at least 3% of patients and at a rate higher than placebo in Surgical Patients for the Prevention of PONV Scopolamine Transdermal System % (N=461) Placebo % (N=457) Dry mouth 29 16 Dizziness 12 7 Somnolence 8 4 Agitation 6 4 Visual Impairment 5 3 Confusion 4 3 Mydriasis 4 0 Pharyngitis 3 2 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of scopolamine transdermal system. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Psychiatric disorders : acute psychosis including: disorientation, hallucinations, and paranoia Nervous system disorders : amnesia, coordination abnormalities, disturbance in attention, headache, restlessness, speech disorder General disorders and administration site conditions : application site reactions (including blistering, burning, pruritus, and rash), and hyperthermia Eye disorders : amblyopia, angle closure glaucoma, dry eyes, eyelid irritation, eye pruritus Skin and subcutaneous tissue disorders : erythema, rash generalized, skin irritation Renal and urinary disorders : dysuria Ear and labyrinth disorders : vertigo
Drug Interactions
Drugs Causing Central Nervous System (CNS) Adverse Reactions : Monitor patients for CNS adverse reactions (drowsiness, dizziness, or disorientations). ( 7.1 ) Anticholinergic Drugs: Consider more frequent monitoring during treatment in patients receiving other anticholinergic drugs. ( 7.2 ) Oral Drugs Absorbed in the Stomach : Monitor for increased or decreased therapeutic effect of the oral drug. ( 7.3) Interaction with Gastric Secretion Test: Discontinue use of scopolamine transdermal system 10 days prior to testing. ( 7.4 ) 7.1 Drugs Causing Central Nervous System (CNS) Adverse Reactions The concurrent use of scopolamine transdermal system with other drugs that cause CNS adverse reactions of drowsiness, dizziness or disorientation (e.g., sedatives, hypnotics, opiates, anxiolytics, and alcohol) or have anticholinergic properties (e.g., other belladonna alkaloids, sedating antihistamines, meclizine, tricyclic antidepressants, and muscle relaxants) may potentiate the effects of scopolamine transdermal system [see Warnings and Precautions (5.2) ] . Either scopolamine transdermal system or the interacting drug should be chosen, depending on the importance of the drug to the patient. If the interacting drug cannot be avoided, monitor patients for CNS adverse reactions. 7.2 Anticholinergic Drugs Concomitant use of scopolamine with other drugs having anticholinergic properties may increase the risk of CNS adverse reactions [see Drug Interactions (7.1) ], intestinal obstruction and/or urinary retention. Consider more frequent monitoring during treatment with scopolamine transdermal system in patients receiving anticholinergic drugs [see Warnings and Precautions (5.2 , 5.4) ] . 7.3 Oral Drugs Absorbed in the Stomach Scopolamine transdermal system, as an anticholinergic, may delay gastric and upper gastrointestinal motility and, therefore, the rate of absorption of other orally administered drugs. Monitor patients for modified therapeutic effect of concomitant orally administered drugs with a narrow therapeutic index. 7.4 Interaction with Gastric Secretion Test Scopolamine will interfere with the gastric secretion test. Discontinue scopolamine transdermal system 10 days prior to testing.
