Pregnancy consideration: Insufficient data available
Lactation: Excretion of the drug in human breast milk is known
Pregnancy category:
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category
Pharmacology:
Pharmacokinetics:
Absorption
After oral administration, acetaminophen/doxylamine/dextromethorphan is readily absorbed from the gastrointestinal tract.
Distribution
acetaminophen/doxylamine/dextromethorphan is widely distributed throughout the body, including the central nervous system.
Metabolism
acetaminophen is primarily metabolized in the liver via microsomal enzyme systems. It undergoes conjugation with glucuronic and sulfuric acids to form inactive metabolites. doxylamine undergoes hepatic metabolism through various pathways, including N-demethylation and hydroxylation. dextromethorphan undergoes extensive hepatic metabolism, primarily via cytochrome P450 enzymes, particularly CYP2D6. It is metabolized to dextrorphan, which has additional activity as an NMDA receptor antagonist.
Elimination and Excretion
acetaminophen/doxylamine/dextromethorphan and its metabolites are mainly excreted in the urine, primarily as glucuronide and sulfate conjugates.
Administration:
acetaminophen/doxylamine/dextromethorphan is available in various forms, including tablets, capsules, liquid suspension, and chewable tablets. It is usually taken orally with a full glass of water.
