Toxicity

A widely abused drug; a sympathomimetic and central stimulant that has been used clinically as an anorectic agent. The use of methamphetamine and related drugs in treating obesity is, however, now generally discredited. It may cause elevation of blood pressure, palpitation, and tachycardia, as well as various CNS effects, including psychotic effects at higher doses. Chronic use of methamphetamine and related compounds, especially at high doses as often occurs with drug abuse, can cause a condition often indistinguishable from schizophrenia. Abrupt withdrawal may cause fatigue, depression, and sleep changes. Methamphetamine is an indirect-acting adrenergic and dopamine agonist that acts principally to release endogenous catecholamines, thereby increasing their synaptic availability. Many of its actions can be blocked by adrenergic and dopamine antagonists. The i.p. LD50 in mice is 70 mg/kg.

D-METHAMPHETAMINE Usage And Synthesis

Originator

Desoxyn ,Abbott Laboratories

Uses

Nasal decongestant.

Definition

ChEBI: A member of the class of amphetamines in which the amino group of (S)-amphetamine carries a methyl substituent.

Manufacturing Process

2 Methods of prepearing of methamphetamine:
1. (-)-Ephedrin was reduced by hydrogenesation with hydrogen in the presence of Pt-C catalyst to give the (+)-N-α-dimethylphenethylamine (methamphetamine), melting point 172°-174°C.
2. Methamphetamine was obtained by the methylation of phenylisopropylamine.
To give methamphetamine hydrochloride the base methamphetamine was treated by eqimolar quantity of hydrochloric acid.
