Q

MOA of Tylenol #3

A

Acetaminophen: Believed to inhibit the synthesis of prostaglandins in the CNS and peripherally block pain impulse generation; produces antipyresis from inhibition of hypothalmic heat-regulating center
Codeine: Binds to opiate receptors in the CNS, causing inhibition of ascending pain pathways, altering the perception of and responses to pain, causes cough suppression by direct central action in the medulla; produces generalized CNS depression
