Bioglandin Injection typically refers to Alprostadil injection, a medication used to treat erectile dysfunction (ED) and certain types of heart conditions. Alprostadil is a synthetic form of prostaglandin E1, a naturally occurring substance in the body that helps widen blood vessels and increase blood flow. In the context of erectile dysfunction, Alprostadil injection is often used when other treatments for ED have not been successful or are not suitable. It works by relaxing the smooth muscle tissue in the penis, allowing blood to flow into the erectile tissue and produce an erection.
