What are the 5alpha reductase inhibitors

The 5-alpha reductase inhibitors are a class of medications that inhibit the enzyme 5-alpha reductase. The enzymes 5-alpha reductase are present in two isoforms type 1 and type 2. Type 1 is found predominantly in extrapr-ostatic tissues such as the skin and liver, although it is also found in the prostate. Type 2 is found predominantly in the prostate. The type 2 5-alpha reductase enzyme in the prostate is responsible for converting testosterone to its active form in the prostate,...

Muse Alprostadil

Intraurethral alprostadil (Vivus's MUSE) is an intraurethral medication (i.e., a drug that is injected into the urethra) that was approved by the FDA in June 1998.

Androgens are primarily produced by the testicles, under control of various parts of the brain. A small number of androgens are produced by the adrenal glands, which are small glands located above the kidneys and produce many important chemicals. Prostate cancer cells may be hormone sensitive, hormone insensitive, or hormone...

What is the success rate of MUSE

In the initial studies of MUSE's effectiveness, the success rate was 64 . More recent studies have demonstrated its efficacy to be only 30 , however. Attempts to increase this success rate via the use of the ACTIS venous constrictor, a constricting band that is placed at the base of the penis, have helped some men. In some men, an erection rigid enough for penetration may occur in the standing position however, when these individuals change to a supine position, the erection may decrease. In...
