Trimix (drug)

Trimix is an injectable three-drug prescribed medication used to treat erectile dysfunction. The active ingredients in the mixture are usually alprostadil, papaverine, and phentolamine. The injection must be compounded by a pharmacy and administered via intracavernosal injection (an injection at either side, not the base, of the penis). Trimix is typically compounded by a pharmacy in a sterile environment and then frozen. The compound is stable for up to six months while stored frozen and for one month if stored refrigerated beginning at the time of manufacture.
