Detail:
Levomethamphetamine is the levorotary (L-enantiomer) form of methamphetamine. Levomethamphetamine is a sympathomimetic vasoconstrictor which is the active ingredient in some over-the-counter (OTC) nasal decongestant inhalers in the United States.
Pharmacology:
Levomethamphetamine crosses the blood-brain-barrier and acts as a TAAR1 agonist, functioning as a selective norepinephrine releasing agent (with few or no effects on the release of dopamine), so it affects the central nervous system, although its effects are qualitatively distinct relative to those of dextromethamphetamine. It does not possess the potential for euphoria or addiction that dextromethamphetamine possesses. Among its physiological effects are the vasoconstriction that makes it useful for nasal decongestion. The elimination half-life of levomethamphetamine is between 13.3 and 15 hours, whereas dextromethamphetamine has a half-life of about 10.5 hours.
Side effects:
When the nasal decongestant is taken in excess, levomethamphetamine has potential side effects resembling those of other sympathomimetic drugs; these effects include hypertension (elevated blood pressure), tachycardia (rapid heart rate), nausea, stomach cramps, dizziness, headache, sweating, muscle tension, and tremors.[citation needed] Central side effects may include anxiety, insomnia, and anorexia (loss of appetite).
Non-medicinal usage:
In a study of psychoactive effects of levomethamphetamine, the intravenous administration of 0.5 mg/kg (but not 0.25 mg/kg) in recreational methamphetamine users produced scores of "drug liking" similar to racemic methamphetamine, but the effects were shorter lived. The study did not test the oral administration of levomethamphetamine. Currently there are no studies demonstrating "drug liking" scores of oral levomethamphetamine that are similar to racemic methamphetamine or dextromethamphetamine in either recreational users or medicinal users.
Detection in body fluids:
Levomethamphetamine can register on urine drug screens as either methamphetamine, amphetamine, or both, depending on the subject's metabolism and dosage. L-methamphetamine metabolizes completely into L-amphetamine after a period of time.
Notes:
Other names include l-methamphetamine, levodesoxyephedrine, l-desoxyephedrine, levmetamfetamine.
The active ingredient in some OTC inhalers in the United States is listed as levmetamfetamine, the INN and USAN of levomethamphetamine.
It is a selective MAOB inhibitor at normal clinical doses. MAOB is an enzyme that metabolizes dopamine, the neurotransmitter deficient in Parkinson's Syndrome.
