Effective Prescription Weight Loss Diet pills are available as prescription drugs and over-the-counter drugs. The former is available with the prescription of your physician or nutritionist. The use of effective prescription weight loss drugs on any individual is not generalized. These diet pills are used to treat obesity. These are recommended for a period of time and are approved by the FDA. Some of the commercially available prescription weight loss medications are mazanor, didrex, bontril, ionamin, tentuate, meridia, sanorex and so on. The basic principle behind their working is the appetite suppressing quality.
Certain medications are available as extended release capsules, which are pills that release the medicine or the active ingredient for a long span. Other kinds of prescription weight loss pills function as fat absorption inhibitor. Xenical is a diet pill, which works by this principle. About 30 per cent of the fat in the food is inhibited from being absorbed. The undigested fat, due to improper lipase functioning is eliminated through the bowels. Appetite suppressants function by stimulating the central nervous system. This increases the secretion of catecholamine or serotonin. These provide the feeling of fullness, as they are chemicals that affect the appetite.
