Bromocriptine

Bromocriptine, an anti-prolactin drug, has been successfully used to treat various conditions, including acne, dandruff, and pituitary tumors 4. It works by inhibiting the production of prolactin, a hormone that promotes the formation of sebum (oil) by the skin, thereby reducing sebaceous gland activity 4. Bromocriptine has also been shown to decrease serotonin and NE activities in the ventromedial hypothalamus (VMH), which may contribute to its ability to improve glucose intolerance and reduce body fat 3.

The effects of bromocriptine on glucose metabolism have been studied in both normal subjects and patients with chemical diabetes. Treatment with bromocriptine for 14 days significantly reduced body fat by 60% and areas under the glucose and insulin curves during a glucose tolerance test by 50 and 46%, respectively 3. Additionally, bromocriptine has been used to treat female infertility, particularly in conditions such as the "Female Athlete Triad" (FAT), which is a reversible form of early-onset menopause 5.

Bromocriptine is also used to treat pituitary tumors because prolactin is promoted by stress, serotonin, or radiation 2. It is based on the indole molecular structure of serotonin but modified to block its effects 2. Other anti-serotonin drugs, such as Ondansetron and Lisuride, have also been developed for various uses, including preventing nausea from radiation exposure 2.

It is worth noting that the use of anti-androgens to treat acne and dandruff has produced mixed results, and bromocriptine has been found to be a more effective treatment for these conditions 4.
