What is Methamphetamine

Methamphetamine is an oral, centrally-acting stimulant used to treat attention-deficit hyperactivity disorder (ADHD) and for the short-term treatment (i.e., a few weeks) of exogenous obesity in conjunction with lifestyle modifications.

However, treatment guidelines do not support the use of methamphetamine for ADHD.

Other stimulants, such as amphetamine and methylphenidate, are highly effective in the treatment of ADHD and are considered first-line therapies.

According to the American Association of Clinical Endocrinologists and American College of Endocrinology (AACE/ACE) Obesity Clinical Practice Guidelines and other guidelines for obesity, short-term pharmacotherapy, such as with the amphetamine anorectics, has not been shown to produce longer-term health benefits in obese and overweight patients and cannot be generally recommended.

Amphetamines should not be used for long-term weight management; tolerance to the anorectic effect usually develops within a few weeks.

The most common adverse effects associated with use of amphetamines include anorexia, abdominal pain, irritability, restlessness, insomnia, emotional lability, and tachycardia.

Stimulants can induce or exacerbate psychiatric symptoms and close monitoring is recommended in patients with pre-existing psychosis or bipolar disorder. Amphetamines have a high potential for abuse and addiction and are contraindicated in patients with a history of substance abuse.

Stimulants have also been associated with sudden death in patients with structural cardiac abnormalities; patients with structural heart defects, cardiomyopathy, or heart-rhythm disturbances may be at risk for adverse cardiac events.

Methamphetamine was approved by the FDA in 1943.
