SUBCUTANEOUS
PRESCRIPTION DRUG
Mepivacaine is indicated for production of local anesthesia for dental procedures by infiltration or nerve block in adults and pediatric patients. Mepivacaine is contraindicated in patients with a known hypersensitivity to amide-type local anesthetics.
Mepivacaine HCl 3%; (Mepivacaine Hydrocholoride Injection USP) is available in cardboard boxes containing 5 blisters of 10 × 1.7 mL dental cartridges, 50 per carton. Mepivacaine HCl 2% (Mepivacaine Hydrochloride and Levonordefrin Injection; USP) is available in cardboard boxes containing 5 blisters of 10 × 1.7 mL dental cartridges, 50 per carton. Both solutions should be stored at controlled room temperature, below 25° C (77° F). Protect from light. Do not permit to freeze. BOXES: For protection from light, retain in box until time of use. Once opened, the box should be reclosed by closing the top flap. The Mepivacaine 2% solution should not be used if its color is pinkish or darker than slightly yellow or it contains a precipitate. Cartridge warmers should not be used with Mepivacaine HCl injection USP products.
Abbreviated New Drug Application
PEARSON MEPIVACAINE- MEPIVACAINE HYDROCHLORIDE INJECTION, SOLUTION PEARSON DENTAL ---------- MEPIVACAINE HCL 3% (MEPIVACAINE HYDROCHLORIDE INJECTION, USP) RX ONLY THESE SOLUTIONS ARE INTENDED FOR DENTAL USE ONLY. DESCRIPTION Mepivacaine Hydrochloride, a tertiary amine used as a local anesthetic, is 1-methyl-2', 6' - pipecoloxylidide monohydrochloride with the following structural formula: It is a white, crystalline, odorless powder soluble in water, but very resistant to both acid and alkaline hydrolysis. Levonordefrin, a sympathomimetic amine used as a vasoconstrictor in local anesthetic solution, is (-)- - (1-Aminoethyl)-3, 4-dihydroxybenzyl alcohol with the following structural formula: It is a white or buff-colored crystalline solid, freely soluble in aqueous solutions of mineral acids, but practically insoluble in water; DENTAL CARTRIDGES MAY NOT BE AUTOCLAVED. Mepivacaine hydrochloride injection 3% and Mepivacaine hydrochloride 2% with levonordefrin 1:20,000 injection are sterile solutions for injection. COMPOSITION CARTRIDGE EACH ML CONTAINS: 2% 3% Mepivacaine Hydrochloride 20 mg 30 mg Levonordefrin 0.05 mg - Sodium Chloride 4 mg 6 mg Potassium metabisulfite 1.2 mg - Edetate disodium 0.25 mg - Sodium Hydroxide q.s. ad pH; Hydrochloric Acid 0.5 mg - Water For Injection, qs. ad. 1 mL 1 mL The pH of the 2% cartridge solution is adjusted between 3.3 and 5.5 with NaOH. The pH of the 3% cartridge solution is adjusted between 4.5 and 6.8 with NaOH. CLINICAL PHARMACOLOGY Mepivacaine stabilizes the neuronal membrane and prevents the initiation and transmission of nerve impulses, thereby effecting local anesthesia. Mepivacaine is rapidly metabolized, with only a small percentage of the anesthetic (5 to 10 percent) being excreted unchanged in the urine. Mepivacaine because of its amide structure, is not detoxified by the circulating plasma esterases. The liver is the principal site of metabolism, with over 50 percent of the administered dose being excreted into the bile as metabolites. Most of the metabolized Mepivac Διαβάστε το πλήρες έγγραφο
