Indications and Usage:
Indications and usage diphenoxylate hydrochloride and atropine sulfate tablets are indicated as adjunctive therapy in the management of diarrhea in patients 13 years of age and older.
Warnings:
Warnings respiratory and/or cns depression in pediatric patients less than 6 years of age cases of severe respiratory depression and coma, leading to permanent brain damage or death have been reported in patients less than 6 years of age who received diphenoxylate hydrochloride and atropine sulfate tablets . diphenoxylate hydrochloride and atropine sulfate tablets are contraindicated in patients less than 6 years of age due to these risks (see contraindications ). anticholinergic and opioid-toxicities toxicities associated with the atropine and diphenoxylate components of diphenoxylate hydrochloride and atropine sulfate tablets have been reported. the initial presenting symptoms may be delayed by up to 30 hours due to prolonged gastric emptying time induced by diphenoxylate hydrochloride. clinical presentations vary in terms of which toxicity (anticholinergic vs. opioid) will present first or predominate; non-specific findings have been reported and include symptoms such as drowsiness

Use in Pregnancy:
Pregnancy diphenoxylate hydrochloride has been shown to have an effect on fertility in rats when given in doses 50 times the human dose (see above discussion). other findings in this study include a decrease in maternal weight gain of 30% at 20 mg/kg/day and of 10% at 4 mg/kg/day. at 10 times the human dose (4 mg/kg/day), average litter size was slightly reduced. teratology studies were conducted in rats, rabbits, and mice with diphenoxylate hydrochloride at oral doses of 0.4 to 20 mg/kg/day. due to experimental design and small numbers of litters, embryotoxic, fetotoxic, or teratogenic effects cannot be adequately assessed. however, examination of the available fetuses did not reveal any indication of teratogenicity. there are no adequate and well-controlled studies in pregnant women. diphenoxylate hydrochloride and atropine sulfate tablets should be used during pregnancy only if the anticipated benefit justifies the potential risk to the fetus.
Pediatric Use:
Pediatric use the safety and effectiveness of diphenoxylate hydrochloride and atropine sulfate tablets have been established in pediatric patients 13 years of age and older as adjunctive therapy in the management of diarrhea. the safety and effectiveness of diphenoxylate hydrochloride and atropine sulfate tablets have not been established in pediatric patients less than 13 years of age. diphenoxylate hydrochloride and atropine sulfate tablets are contraindicated in pediatric patients less than 6 years of age due to the risks of severe respiratory depression and coma, possibly resulting in permanent brain damage or death (see contraindications ). diphenoxylate hydrochloride and atropine sulfate tablets have caused atropinism, particularly in pediatric patients with downâs syndrome (see precautions ). in case of accidental ingestion of diphenoxylate hydrochloride and atropine sulfate tablets by pediatric patients, see overdosage for recommended treatment.
Overdosage:
Overdosage diagnosis overdosage can be life-threatening. symptoms of overdosage may include opioid and/or anticholinergic effects including respiratory depression, coma, delirium, lethargy, dryness of the skin and mucous membranes, mydriasis or miosis, flushing, hyperthermia, tachycardia, hypotonia, tachypnea, toxic encephalopathy, seizures and incoherent speech. respiratory depression has been reported up to 30 hours after ingestion and may recur despite an initial response to narcotic antagonists. treat all possible diphenoxylate hydrochloride and atropine sulfate overdosages as serious and maintain medical observation/hospitalization until patients become asymptomatic without naloxone use. treatment a pure narcotic antagonist (e.g., naloxone) should be used in the treatment of respiratory depression caused by diphenoxylate hydrochloride and atropine sulfate tablets. refer to the prescribing information for naloxone. consider diphenoxylate hydrochloride and atropine sulfate toxicity even in settings of negative toxicology tests. following initial improvement of respiratory function, repeated doses of naloxone hydrochloride may be required to counteract recurrent respiratory depression. if over-exposure occurs, call your poison control center at 1-800-222-1222 for current information on the management of poisoning or overdosage.

Clinical Pharmacology:
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 under the plasma concentration-time curve, and the amount of diphenoxylic acid excreted in the ur

Carcinogenesis and Mutagenesis and Impairment of Fertility:
Carcinogenesis, mutagenesis, impairment of fertility no long-term study in animals has been performed to evaluate carcinogenic potential. diphenoxylate hydrochloride was administered to male and female rats in their diets to provide dose levels of 4 and 20 mg/kg/day throughout a three-litter reproduction study. at 50 times the human dose (20 mg/kg/day), female weight gain was reduced and there was a marked effect on fertility as only 4 of 27 females became pregnant in three test breedings. the relevance of this finding to usage of diphenoxylate hydrochloride and atropine sulfate tablets in humans is unknown.
