bupivacaine hcl - Medication Listings

Bupivacaine hydrochloride injection contains bupivacaine hydrochloride, an amide local anesthetic, as the active pharmaceutical ingredient. The route of administration for bupivacaine hydrochloride injection is by injection, for infiltration, perineural, caudal, epidural, or retrobulbar use. [see Warnings and Precautions (5.4) ] . Bupivacaine hydrochloride is 2-piperidinecarboxamide, 1-butyl- N -(2,6-dimethylphenyl)-, monohydrochloride, monohydrate. It is a white crystalline powder that is freely soluble in 95 percent ethanol, soluble in water, and slightly soluble in chloroform or acetone. It has the following structural formula: Bupivacaine hydrochloride injection is a clear and colorless sterile isotonic solution. Each mL of multiple-dose vial contains 2.5 mg, 5 mg of bupivacaine hydrochloride (equivalent to 2.22 mg, 4.44 mg of bupivacaine, respectively), sodium chloride for isotonicity, sodium hydroxide or hydrochloric acid to adjust the pH between 4 and 6.5 in water for injection. For the Multiple-dose vials, each mL also contains 1 mg methylparaben as preservative. Chemical Structure

It has the following structural formula: Bupivacaine hydrochloride injection is a clear and colorless sterile isotonic solution. Each mL of single-dose vial contains 2.5 mg, 5 mg or 7.5 mg of bupivacaine hydrochloride (equivalent to 2.22 mg, 4.44 mg or 6.66 mg of bupivacaine, respectively), sodium chloride for isotonicity, sodium hydroxide or hydrochloric acid to adjust the pH between 4 and 6.5, in water for injection.

Sensorcaine ® (bupivacaine HCl) injections are sterile isotonic solutions that contain a local anesthetic agent with and without epinephrine (as bitartrate) 1:200,000 and are administered parenterally by injection. See INDICATIONS AND USAGE for specific uses. Solutions of bupivacaine HCl may be autoclaved if they do not contain epinephrine. Sensorcaine injections contain bupivacaine HCl which is chemically designated as 2- piperidinecarboxamide, 1-butyl- N-(2,6-dimethylphenyl)-, monohydrochloride, monohydrate and has the following structure: Epinephrine is (-)-3,4-Dihydroxy-α [(methylamino)methyl] benzyl alcohol. It has the following structural formula: The pK a of bupivacaine (8.1) is similar to that of lidocaine (7.86). However, bupivacaine possesses a greater degree of lipid solubility and is protein bound to a greater extent than lidocaine. Bupivacaine is related chemically and pharmacologically to the aminoacyl local anesthetics. It is a homologue of mepivacaine and is chemically related to lidocaine. All three of these anesthetics contain an amide linkage between the aromatic nucleus and the amino, or piperidine group. They differ in this respect from the procaine-type local anesthetics, which have an ester linkage. Dosage forms listed as Sensorcaine-MPF indicates s ingle dose solutions that are Methyl Paraben Free (MPF). Sensorcaine-MPF is a sterile isotonic solution containing sodium chloride. Sensorcaine in multiple dose vials, each mL also contains 1 mg methylparaben as antiseptic preservative. The pH of these solutions is adjusted to between 4.0 and 6.5 with sodium hydroxide and/or hydrochloric acid. Sensorcaine-MPF with Epinephrine 1:200,000 (as bitartrate) is a sterile isotonic solution containing sodium chloride. Each mL contains bupivacaine hydrochloride and 0.005 mg epinephrine, with 0.5 mg sodium metabisulfite as an antioxidant and 0.2 mg citric acid (anhydrous) as stabilizer. Sensorcaine with Epinephrine 1:200,000 (as bitartrate) in multiple dose vials, each mL also contains 1 mg methylparaben as antiseptic preservative. The pH of these solutions is adjusted to between 3.3 to 5.5 with sodium hydroxide and/or hydrochloric acid. Filled under nitrogen. Note: The user should have an appreciation and awareness of the formulations and their intended uses (see DOSAGE AND ADMINISTRATION). S1 S2
