Acetaminophen-Propoxyphene Napsylate Chemical Information

acetaminophen - An acetanilide with analgesic and antipyretic activity. Although the exact mechanism through which acetaminophen exert its effects has yet to be fully determined, this agent probably acts by inhibiting prostaglandin synthesis in the central nervous system (CNS). Inhibition of prostaglandin synthesis in the CNS results in elevation of the pain threshold and lowering of the thermal set point in the hypothalamus.

propoxyphene napsylate - A synthetic diphenyl propionate derivative structurally related to methadone, Propoxyphene Napsylate acts as a central narcotic and analgesic agent by interaction with mu opioid receptors, but with less selectivity then morphine. The dextro-isomer has analgesic effect, while the levo-isomer exerts an antitussive effect. The napsylate salt allows better dosage formulation than the hydrochloride salt. (NCI04)
