NCIt definition : An opiate alkaloid isolated from the plant Papaver somniferum and produced synthetically.
As a direct-acting smooth muscle relaxant, papaverine is not closely related to the
other opium alkaloids in structure or pharmacological actions; its mechanism of action
may involve the non-selective inhibition of phosphodiesterases and direct inhibition
of calcium channels. This agent also exhibits antiviral activity against respiratory
syncytial virus, cytomegalovirus, and HIV. (NCI04);
