Anabolic androgenic steroids (AAS) and testosterone are the most frequently detected prohibited doping agents in sport. Professional competitors have been taking them since the fifties of the 20th century, they are used at present mainly by sport amateurs. Anabolic Androgenic Steroids are very often used in combination with other doping agents (erythropoietin, growth hormone, thyroxin). Apart f...

Osteoporosis results from a loss of bone mass and bone structure such that the bone becomes weak and fractures with very little trauma. Until recently, the approved osteoporosis therapies prevented more bone loss by altering osteoclast activity and lifespan. Recently, attention has turned away from osteoclast inhibition to agents that can stimulate the osteoblast to form new bone, or anabolic a...

Antiresorptive agents for osteoporosis are a cornerstone of therapy, but anabolic drugs have recently widened our therapeutic options. By directly stimulating bone formation, anabolic agents reduce fracture incidence by improving bone qualities besides increasing bone mass. In this article, we review the role of anabolic treatment for osteoporosis. The only anabolic agent currently approved in ...

The metabolic fate of the anabolic agents, diethylstilbestrol, hexestrol, trenbolone acetate, zeranol and the endogenous steroids are discussed under the headings absorption, distribution and excretion. There is an optimum concentration of anabolic agent in the systemic circulation that results in a maximum increase in growth rate of farm animals. This optimum blood concentration should be main...

There are preclinical studies and limited clinical experiences with bone and muscle anabolic agents (e.g., parathyroid hormone (PTH), sodium fluoride (NaF), prostaglandins (PGs), growth hormones (GH), etc.) that show they have significant advantages over antiremodeling agents in patients with established osteoporosis. The strength of anabolic therapy is as follows: it rapidly reverses bone loss...

The sportsmen self-administering androgenic-anabolic agents to improve their performance and their body shape continue to be a problem. After the opening of the East European borders a large number of compounds are offered on the black market and in fitness centres. As a consequence students and children practicing no sport use these agents. Most athletes have only a crude pharmacological knowl...
