HYDROCODONE BITARTRATE AND HOMATROPINE METHYLBROMIDE (homatropine methylbromide)

Respiratory Approved 1983-03-03

Hydrocodone bitartrate and homatropine methylbromide oral solution is indicated for the symptomatic relief of cough in adults 18 years of age and older. Use is reserved for patients in whom the benefits of cough suppression outweigh the risks of opioid addiction, abuse, and misuse, and only after a thorough evaluation of the cough's underlying etiology. It is not indicated for pediatric use and is contraindicated in children under 6 years of age.

How HYDROCODONE BITARTRATE AND HOMATROPINE METHYLBROMIDE Works

This combination product consists of hydrocodone, an opioid agonist, and homatropine, a muscarinic antagonist. Hydrocodone exhibits relative selectivity for the mu-opioid receptor and is believed to suppress cough by acting centrally on the cough center in the brain. Homatropine methylbromide is an anticholinergic that inhibits muscarinic acetylcholine receptor activity with less potency than atropine; it is typically included in this formulation to discourage deliberate overdosage.
