Pharmacology

Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor; it produces analgesia by binding with high affinity to opioid receptors on neurons in the brain and spinal cord and, unlike full opioid agonists, exhibits a dose-ceiling effect on respiratory depression.

Ziconotide is an N-type calcium channel blocker; it binds to N-type calcium channels on primary nociceptive afferent nerves in the dorsal horn of the spinal cord, blocking excitatory neurotransmitter release from afferent nerve terminals and producing antinociception.
