. The bioavailability of Ionamin has been studied in humans in which blood levels of phentermine were measured by a gas chromatography method. Tachyphylaxis and tolerance have been demonstrated with all drugs of this class in which these phenomena have been looked for. Drugs of this class used in obesity are commonly known as "anorectics" or "anorexigenics. The natural history of obesity is measured in years, whereas the studies cited are restricted to a few weeks' or months' duration; thus, the total impact of drug-induced weight loss over that of diet alone must be considered clinically limited. Blood levels obtained with the 15 mg and 30 mg resin complex formulations indicated slower absorption with a reduced but prolonged peak concentration and without a significant difference in prolongation of blood levels when compared with the same doses of phentermine hydrochloride. Drugs of this class used in obesity are commonly known as "anorectics" or "anorexigenics. CLINICAL PHARMACOLOGY: Ionamin is a sympathomimetic amine with pharmacologic activity similar to the prototype drug of this class used in obesity, amphetamine (d- and dl-amphetamine). The rate of weight loss is greatest in the first weeks of therapy for both drug and placebo subjects and tends to decrease in succeeding weeks. The magnitude of increased weight loss of drug-treated patients over placebo-treated patients is only a fraction.
