Fosamax is an inhibitor of bone resorption of the bisphosphanate group. The preparation contains the active ingredient - sodium alendronate. Localized in foci of active bone resorption, the drug inhibits this pathological process caused by osteoclasts, while not directly affecting the formation of new bone tissue. The processes of formation and resorption of bone tissue are interrelated, therefore, under the influence of Fosamax, bone formation is also reduced, but to a lesser extent than the process of resorption. The result is a progressive increase in bone mass. During treatment with this drug, normal bone tissue is formed, into the structure of which the pharmacologically inactive alendronate is embedded. At a therapeutic dosage, Fosamax does not cause osteomalacia. This drug has proven itself in the treatment of postmenopausal osteoporosis in women,significantly increasing bone density, due to which the reviews about Fosamax are positive. Clinical research data indicate a high activity of the drug.

When taken orally, Fosamax at a dosage of 5-70mg 2 hours before a regular breakfast, bioavailability is about 0.6%. With a later intake, bioavailability decreases by 40%. When Fosamax is taken simultaneously with food or after a meal, its bioavailability is negligible. There is no data on the ability of the drug to be metabolized in the human body.

In the amount of 50%, the drug is excreted by the kidneys. The terminal half-life of Fosamax is about 10 years, which indicates its release from the bone.
