Abuse of drugs used to enhance athletic performance.
The ergogenic potential of drugs used by athletes to enhance performance is reviewed, and areas of involvement for pharmacists interested in the problem of drug abuse in athletics are described. Athletes use drugs for therapeutic and recreational purposes, as supposed ergogenic aids, and to mask the presence of other drugs during testing. Because many athletes train for competition and not for health, they may view the risk-to-benefit ratio of ergogenic drugs as favorable and may begin using them at an early age. Alcohol is the drug most commonly used by student athletes. Although alcohol has no ergogenic benefit, it is viewed as a caloric source and an anxiolytic. Amphetamines do not prevent exhaustion but may mask fatigue, which can have dangerous consequences. Anabolic steroids appear to increase strength but frequently cause adverse reactions, primarily involving the hepatic and endocrine systems. Beta-blocking agents have been shown to reduce anxiety, hand tremor, and heart rate in precision sports like archery, but susceptible persons may experience serious adverse effects. Caffeine improves the efficiency of fuel use and reduces fatigue; its use has been banned by several athletic organizations. Neither cocaine nor marijuana causes any increase in strength. Secretion of human growth hormone may be stimulated by a variety of agents, but evidence that any subsequent increases in size and weight occur is lacking. Other substances tried by athletes include vitamins and minerals, naloxone, albuterol, and human recombinant erythropoietin. Opportunities in sports pharmacy exists in the areas of information retrieval and interpretation, drug testing, legislation to reclassify drugs, education, and research.(ABSTRACT TRUNCATED AT 250 WORDS)
