Question

Quizplus · Accepted Answer

Acetaminophen acts as a mild analgesic and antipyretic by inhibiting prostaglandin synthesis in the central nervous system and by reducing the activity of cyclooxygenase enzymes in the peripheral tissues. This effect helps to reduce pain at the peripheral site. Morphine and codeine are opioid analgesics, which act on the central nervous system to block pain signals. Intravenous general anesthesia produces a state of unconsciousness and lack of sensation, rather than targeted reduction of pain at the peripheral site.
