Transurethral Agents - Erectile Dysfunction

What is a "transurethral agent"?

Transurethral agents, also called intra-urethral agents, are erectile dysfunction (ED) treatments whose mode of administration is insertion into the urine channel, known as the urethra. The only FDA-approved urethral suppository is called MUSE® (Medicated Urethral System for Erection), which contains the drug alprostadil (also used in the injectable drugs, Caverject and Edex).
