Amphetamines: pharmacology, abuse and addiction

Area of Science:

• Pharmacology
• Medicinal Chemistry
• Neuroscience

Background:

• Amphetamine (beta-phenylisopropylamine) is a potent sympathomimetic amine with diverse biological effects, including CNS stimulant actions.
• Since the 1930s, chemical modifications of the amphetamine molecule have led to the development of various selective sympathomimetics.
• These include CNS stimulants, psychomimetics, anorectic agents, and vasoconstrictors, all sharing the basic amphetamine skeleton.

Purpose of the Study:

• To review the development and biological effects of amphetamine and its derivatives.
• To highlight the synthesis of selectively acting sympathomimetics through chemical modifications.
• To discuss the persistent issue of abuse and addiction associated with these central nervous system stimulants.

Main Methods:

• Literature review of pharmacological and medicinal chemistry studies.
• Analysis of chemical modifications of the amphetamine structure.
• Examination of reports on the consequences of abuse and addiction.

Main Results:

• Amphetamine exhibits hyperthermic, anorectic, cardiovascular, and CNS stimulant effects.
• Chemical modifications have produced drugs with emphasized or diminished specific amphetamine properties.
• A variety of selective sympathomimetics, including CNS stimulants and psychomimetics, have been synthesized.
• Abuse and addiction issues have closely followed the development of these agents.
• Both legitimate and illicit production contribute to significant use of CNS stimulants.

Conclusions:

• Amphetamine derivatives offer a range of pharmacological effects due to structural modifications.
• Central nervous system stimulants are highly reinforcing, leading to their continued use and abuse.
• The development of amphetamine-based drugs necessitates ongoing attention to addiction and abuse potential.
