DIPHENOXYLATE HYDROCHLORIDE AND ATROPINE SULFATE- DIPHENOXYLATE HYDROCHLORIDE AND ATROPINE SULFATE TABLET RPK PHARMACEUTICALS, INC. ---------- DIPHENOXYLATE HYDROCHLORIDE AND ATROPINE SULFATE TABLETS, FOR ORAL USE, C-V DESCRIPTION Each diphenoxylate hydrochloride and atropine sulfate tablet, USP contains: 2.5 mg of diphenoxylate hydrochloride, USP (equivalent to 2.3 mg of diphenoxylate) and 0.025 mg of atropine sulfate, USP (equivalent to 0.01 mg of atropine) Diphenoxylate hydrochloride, an antidiarrheal, is ethyl 1-(3-cyano-3,3-diphenylpropyl)-4- phenylisonipecotate monohydrochloride and has the following structural formula: Atropine sulfate, an anticholinergic, is endo-(±)-alpha-(hydroxymethyl) benzeneacetic acid 8-methyl-8- azabicylo[3.2.1] oct-3-yl ester sulfate (2:1)] (salt) monohydrate and has the following structural formula: A subtherapeutic amount of atropine sulfate is present to discourage deliberate overdosage. Inactive ingredients of diphenoxylate hydrochloride and atropine sulfate tablets include colloidal silicon dioxide, lactose monohydrate, microcrystalline cellulose, pregelatinized starch and stearic acid. CLINICAL PHARMACOLOGY Diphenoxylate is rapidly and extensively metabolized in man by ester hydrolysis to diphenoxylic acid (difenoxine), which is biologically active and the major metabolite in the blood. After a 5-mg oral dose of carbon-14 labeled diphenoxylate hydrochloride in ethanolic solution was given to three healthy volunteers, an average of 14% of the drug plus its metabolites was excreted in the urine and 49% in the feces over a four-day period. Urinary excretion of the unmetabolized drug constituted less than 1% of the dose, and diphenoxylic acid plus its glucuronide conjugate constituted about 6% of the dose. In a 16- subject crossover bioavailability study, a linear relationship in the dose range of 2.5 to 10 mg was found between the dose of diphenoxylate hydrochloride (given as diphenoxylate hydrochloride and atropine sulfate liquid) and the peak plasma concentration, the area u Olvassa el a teljes dokumentumot
