How does Propecia(Finasteride) work?
October 23rd, 2007 Posted by: admin
Testosterone floating in the bloodstream of the typical adult male routinely combines with an enzyme called 5-alpha reductase. The result of this interaction forms the more potent sexual hormone known as DHT (Dihydrotestosterone). DHT plays a primary role in proper sexual organ development during the fetal stage of life, as well as the proper development of secondary male characteristics during puberty.
When a man begins to lose his hair, certain genetically programmed follicles begin to develop DHT receptor sites. The DHT attaches itself to these receptor sites and begins to treat the follicle as a foreign object in the body. This chemical change not only affects hair, can cause itching, inflammation, and oiliness. During this time, the follicle, under the attack of DHT, begins to miniaturize with every growth cycle, until after several years, it simply is too small and short to be seen.
When Propecia is taken, it works to inhibit the formation of DHT in the system. Within a few months, the overall DHT levels will have remained low enough on a constant basis that the adverse effects DHT is having on the follicles will stop, resulting in a cessation of hair loss.
Propecia (Finasteride) belongs to a group of medicines called “5 alpha reductase inhibitors”. It is a tan octagonal tablet, which is swallowed and is available in just one strength - 1mg.
Propecia (Finasteride) works by blocking the enzyme, Type II 5 alpha-reductase, and in doing so it reduces the level of the hormone in the scalp which shortens the hair growth cycle and allows hairs to revert to a normal growth cycle. This can result in stopping further hair loss and increasing new hair growth in men with male pattern baldness (androgenetic alopecia).
Continuous use once a day for 3–6 months is required before benefit is seen, and effects are reversed 6–12 months after treatment is discontinued so continuous use is recommended to sustain benefit.You have big dicounts propecia if you decide to buy propecia now.
