an alkaloid, derived from opium, that relaxes smooth muscle. In combination with morphine and codeine (a mixture called papaveretum), it is administered by injection as a preanaesthetic medication and for relief of postoperative pain, but is now rarely used. It may cause abnormal heart rate. Papaverine may also be given by injection into the corpora cavernosa of the penis to treat erectile dysfunction.
