PRESCRIPTION DRUG
Diphenoxylate hydrochloride is effective as adjunctive therapy in the management of diarrhea. Diphenoxylate hydrochloride is contraindicated in patients with: - Known hypersensitivity to diphenoxylate or atropine. - Obstructive jaundice. - Diarrhea associated with pseudomembranous enterocolitis or enterotoxin-producing bacteria. Diphenoxylate hydrochloride is classified as a Schedule V controlled substance by federal regulation. Diphenoxylate hydrochloride is chemically related to the narcotic analgesic meperidine. In doses used for the treatment of diarrhea, whether acute or chronic, diphenoxylate has not produced addiction. Diphenoxylate hydrochloride is devoid of morphine-like subjective effects at therapeutic doses. At high doses it exhibits codeine-like subjective effects. The dose which produces antidiarrheal action is widely separated from the dose which causes central nervous system effects. The insolubility of diphenoxylate hydrochloride in commonly available aqueous media precludes intravenous self-

DIPHENOXYLATE HYDROCHLORIDE AND ATROPINE SULFATE- DIPHENOXYLATE HYDROCHLORIDE AND ATROPINE SULFATE TABLET APHENA PHARMA SOLUTIONS - TENNESSEE, LLC ---------- DIPHENOXYLATE HYDROCHLORIDE AND ATROPINE SULFATE CV, TABLETS, USP DESCRIPTION Each diphenoxylate hydrochloride and atropine sulfate tablet contains: diphenoxylate hydrochloride 2.5 mg atropine sulfate 0.025 mg 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-(±)-α-(hydroxymethyl) benzeneacetic acid 8-methyl-8- azabicyclo[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 tablets include acacia, corn starch, magnesium stearate, sorbitol, sucrose, and talc. 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 liquid) and the peak plasma concentration, the area under the plasma concentration-time curve, and the amount of diphenoxylic acid excreted in the urine. In the same study the bioavailability of the tablet compared with an equal dose of the Baca dokumen lengkap
