Allows performance beyond the usual pain threshold. Some painkillers raise blood pressure , increasing oxygen supply to muscle cells. Painkillers used by athletes range from common over-the-counter medicines such as NSAIDs such as ibuprofen to powerful prescription narcotics. Sedatives and anxiolytics are used in sports like archery which require steady hands and accurate aim, and also to overcome excessive nervousness or discomfort for more dangerous sports.
Diazepam , nicotine, and propranolol are common examples. Ethanol , the most commonly used substance by athletes, can be used for cardiovascular improvements though has significant detrimental effects. Ethanol was formerly banned by WADA during performance for athletes performing in aeronautics, archery, automobile, karate, motorcycling and powerboating, but was taken off the ban list in It is detected by breath or blood testing.
Cannabis is banned at all times for an athlete by WADA, though performance-enhancing effects have yet to be studied. Cannabis and nicotine are detected through urine analysis. Blood doping agents increase the oxygen-carrying capacity of blood beyond the individual's natural capacity.
Recombinant human erythropoietin rhEPO is one of the most widely known drugs in this class. Erythropoietin, or EPO, is a hormone that helps increase the production of red blood cells which increases the delivery of oxygen to muscles. Gene doping agents are a relatively recently described class of athletic performance-enhancing substances.
Also known as anabolic steroid precursors, they promote lean body mass. While the use of PEDs has expanded in recent times, the practice of using substances to improve performance has been around since the Ancient Olympic Games.
were used by the Roman Gladiators to overcome injuries and fatigue. In the late 19th century as modern medicine and pharmacology were developing, PEDs saw an increase in use. In the 20th century, testosterone was isolated and characterized by scientists.
In the s, the main PEDs were cortisone and anabolic steroids. Adolescents are the most vulnerable group when it comes to taking performance-enhancing substances. In sports, the term performance-enhancing drugs is popularly used in reference to anabolic steroids or their precursors hence the colloquial term "steroids" ; anti-doping organizations apply the term broadly.
When medical exemptions are granted they are called therapeutic use exemptions. Contents move to sidebar hide. Article Talk. Read Edit View history.

The first aim of this paper was to review current trends in the misuse of smart drugs also known as Nootropics presently available on the market focusing in detail on methylphenidate, trying to evaluate the potential risk in healthy individuals, especially teenagers and young adults.
Better Fighting Through Chemistry? The Role of FDA Regulation in Crafting the Warrior of the Future. Food and Drug Law: Final Paper. Retrieved 4 March Like EPO, human growth hormone hGH occurs naturally in the body. In fact, the pituitary gland , the pea-sized organ located at the base of the brain, produces hGH to stimulate growth in children and adolescents and to increase muscle mass in adults.
As soon as synthetic hGH became available as a prescription medication in , when the U. Food and Drug Administration approved its use for a number of diseases that retard growth or cause muscle deterioration, athletes began eyeing it as a doping agent. They figured it could mimic the muscle-building effects of anabolic steroids.
At first, the high cost of the medication discouraged widespread use as a PED, but, as the saying goes, where there's a will to win, there's a way. The Summer Olympic Games have been called the "hGH Games" because of the rampant use of the drug among competitors.
And it continues to be a problem among athletes. In summer , Nigerian sprinter Blessing Okagbare was kicked out of the Tokyo Olympics after testing positive for hGH.
Today, athletes get hGH from a variety of sources: doctors willing to write prescriptions for off-label use, online pharmacies, illicit websites for performance-enhancing drugs and clinics that use the hormone to reverse the effects of aging.
A few athletes even turn to black-market dealers that collect hGH from human cadavers. It's a risky gamble, especially considering the lack of scientific evidence to suggest that hGH actually increases athletic performance.
Oh, and don't forget the side effects. Using hGH has been linked to a variety of medical conditions, including joint pain, muscle weakness, fluid retention, carpal tunnel syndrome, cardiomyopathy and hyperlipidemia [source: Mayo Clinic ].
Another performance-enhancing drug that made the Summer Olympic Games memorable for the wrong reason was bromantane, a sort of stimulant and masking agent combined. Several Russians tested positive for the drug, which at the time was not included on the International Olympic Committee's IOC's list of banned substances.
That didn't stop the IOC from disqualifying several Russian athletes, stripping medals from two and ultimately blacklisting bromantane based on its performance-enhancing effects. The effects of bromantane are quite unlike any other PED. Russian army doctors developed bromantane as a stimulant, something they could give to soldiers and cosmonauts to help them feel more alert and fight fatigue.
Soon after, Russian athletes got hold of the drug, reporting that it helped them perform at peak levels without feeling exhausted. Some anti-doping officials believe bromantane can hide the abuse of more serious drugs, such as steroids.
Known as masking, this is just one more way athletes can find a way to cheat. For example, the masking agent probenecid stops the excretion of steroids for a few hours, decreasing the concentration of steroids in the urine.
The exact masking mechanism of bromantane, however, remains unclear. Bromantane gained popularity because it appealed on multiple fronts. But stimulants by themselves function reasonably well as performance-enhancing substances. Athletes take stimulants to improve athletic performance, reduce fatigue and increase aggressiveness.
And someone trying to qualify for a lower weight class may rely on stimulants for their ability to suppress appetite. You may think first of amphetamines — prescription-only "speed" pills — when you hear of this class of drugs, but not all stimulants require a physician's signature.
Ephedrine, for example, is available behind the counter in drug products, mostly as decongestants. Dietary supplements containing ephedrine are illegal in the U. Athletes, of course, aren't interested in these. They want ephedrine for an extra boost of energy despite the warnings that the drug can cause high blood pressure, dizziness, shortness of breath and cardiac arrhythmia.
Along with bromantane, diuretics have long served to mask steroid use. Diuretics are any drugs that affect kidney function, resulting in increased urine output. The "water pill" chlorthalidone , for example, prevents kidney tubules from reabsorbing fluids and salts and returning them to the blood.
As a result, more water leaves the body. In patients with certain conditions, such as heart disease, diuretics can also help control high blood pressure. But athletes who take anabolic steroids pop diuretics to dilute their urine, which decreases steroid concentration and makes it much more difficult to detect during drug testing.
Of course, there is testing for diuretics, too. Weightlifters and boxers may also down water pills to expel large amounts of fluid, which qualifies them to compete in a lower weight category.
Then, right before the match, they stop taking the pills to return to their heavier fighting weight, giving them an advantage against their opponent. However, an athlete taking diuretics may also get dizzy, become dehydrated or experience a severe drop in blood pressure — symptoms that make it hard to compete.
Sometimes, a drug's effect on athletic performance depends on how it's administered. For example, the well-known asthma drug albuterol works by relaxing the muscles lining the bronchial tubes, allowing more air to flow into the lungs.
Athletes with asthma believe it or not, elite athletes tend to have higher rates of asthma than people in the general population commonly use inhaled albuterol to treat their symptoms, allowing them to compete without shortness of breath [source: Kindermann ].
But what about athletes who don't have asthma? Could they suck in a few shots of albuterol and increase their lung capacity?
According to research published in the journal Sports Medicine, this performance-enhancing effect simply doesn't exist. The authors found that, in 17 of 19 clinical trials involving non-asthmatic competitive athletes, the performance-enhancing effects of inhaled beta2-agonists could not be proved.
All bets are off, however, when an athlete takes albuterol orally or by injection. When administered in this fashion, albuterol has anabolic properties, which means it can help build muscle like steroids and, according to a study published in the British Journal of Sports Medicine, it can also boost sprint and strength performance.
Another orally ingested beta2-agonist known as clenbuterol aka clen packs an even bigger punch than albuterol. Athletes in several sports — cycling, swimming, baseball and soccer — have tested positive for clenbuterol use, although many have claimed that the drug could be traced to contaminated food.
While clenbuterol has historically been given to animals to produce leaner meat, the U. banned its use in meat in and the European Union followed suit in If the acronym sounds familiar, it probably is. GHB is known as a "date rape" drug because it can quickly render a user so relaxed and euphoric — especially when combined with alcohol — that they are easily taken advantage of.
Even scarier, it can cause amnesia, improving the chances that predators who slip the tasteless chemical into an unsuspecting imbiber's cocktail will get away with their misdeeds. Because of the risks it posed, the Drug Enforcement Administration DEA banned GHB in but then brought it back to the market two years later after it was found to be useful in treating narcolepsy.
Its use has since expanded to include another rare sleeping disorder, but GHB is only prescribed under strict safety controls.
Even before it gained infamy as a date rape drug, GHB was thought to improve exercise performance and muscle mass. There's even some scientific evidence that GHB increases growth hormone concentration. performance - enhancing drug noun.
Rich et al. Roger Bannister, the first person to run a subpar four-minute mile, said today he thought that increased use of blood testing could help curb the use of performance-enhancing drugs by track and field athletes.
