DIET PILSS NEED?
Overall, in carefully selected patients, a doctor may prescribe appropriate drugs to be used in conjunction with diet and exercise to achieve weight loss. The only drugs recommended for use by the National Heart, Lung, and Blood Institute (NHLBI) are those that have been approved by the U.S. Food and Drug Administration (FDA). FDA-approved drugs have been studied and determined to be safe and effective for some, but not all, people.
According to the NHLBI, people who are appropriate candidates and should consider taking diet pills are adults with a BMI of greater than 30 kg/m2 or those with a BMI of higher than 27 kg/m2 who have health problems related to being overweight. Diet pills, like any other medication, have risks associated with their use. Therefore, diet pills should only be used by people who are at high risk of developing weight-related health problems. For people who are obese or overweight, the benefits of weight loss are generally greater than the risks associated with taking slimming pills. Several slimming pills have been studied for use in children; however, doctors only recommend using them in extreme situations.
The National Institutes of Health (NIH) has established guidelines on the use of diet pills. These guidelines are used by health-care practitioners both within and outside the United States. The information contained in these guidelines helps to determine who should and should not use weight loss medications. This is important because people who use diet pills inappropriately risk potentially devastating effects on their health.
ERECTION DRUGS NEED?When a man is aroused, nerve signals are sent from the brain and around the penis. These nerve signals cause chemicals to be released that relax the muscles in the penis. Normally, these muscles are constricted so that blood cannot flow into the penis. When these muscles relax, large amounts of blood are able to enter the penis, causing an erection. An erection is reversed when another chemical (known as phosphodiesterase type 5 [PDE5]) breaks down the chemicals that caused the muscles to relax in the first place. This causes the muscles in the penis to constrict again as blood leaves the penis. Cialis works by blocking PDE5. When PDE5 is blocked, more of the chemicals responsible for the erection remain, so the muscles in the penis do not constrict. This allows blood to stay in the penis longer, which allows the man to maintain an erection.
HAIR GROW DRUGS NEED?With at least forty treatments for baldness patented in 1996 and $200 million budgeted for clinical trials in 1997, you'd think someone might have figured out by now why men lose hair. But the lab guys know only one big thing: Hair follicles shrink and die. They've proved that this tragedy is triggered by the body's especially potent testosterone derivative, DHT. But researchers can still only theorize about why the perfectly normal presence of DHT leaves some otherwise healthy men mourning their hair as it swirls down the drain.
Propecia, the next treatment to grind its way through the FDA-approval machinery, probably within the year, will be Merck's promising finasteride tablet, Propecia. Finasteride inhibits the enzyme that turns testosterone into DHT--the first domino in the chain reaction that ends in follicle death. It first appeared in the guise of Proscar, a drug that combats prostate enlargement, another problem caused by DHT. Merck's trial results have raised high hopes for Propecia's effectiveness: More than half of those treated had "clinically significant increases in growth of new hair." Some baldsters, wanting to get the jump on the approval process, are already cadging prescriptions for Proscar from their physicians.
