hydrocodone bitartrate and homatropine methyl-bromide

Hycodan

Pharmacologic class: Opioid agonist/nonopioid analgesic combination

Therapeutic class: Opioid analgesic; allergy, cold, and cough remedy (antitussive)

Controlled substance schedule III

Pregnancy risk category C

Action

Blocks release of inhibitory neurotransmitters, altering perception of and emotional response to pain. Hydrocodone/ibuprofen combination raises pain threshold by nonselectively inhibiting cyclooxygenase; prostaglandin synthesis then decreases and anti-inflammatory and analgesic effects occur.
