Pathway Description
Alfentanil Action Pathway
Homo sapiens
Drug Action Pathway
Alfentanil (also known as Alfenta or Rapifen) is analgesic that can bind to mu-type opioid receptor to activate associated G-protein in the sensory neurons of central nervous system (CNS), which will reduce the level of intracellular cAMP by inhibiting adenylate cyclase. The binding of alfentanil will eventually lead to reduced pain because of decreased nerve conduction and release of neurotransmitter. Hyperpolarization of neuron is caused by inactivation of calcium channels and activation of potassium channels via facilitated by G-protein.
