DARK Classics in Chemical Neuroscience: Methaqualone

Area of Science:

• Pharmacology
• Neuroscience
• Medicinal Chemistry

Background:

• Methaqualone (Quaaludes) is a sedative-hypnotic with barbiturate-like effects.
• It acts via modulation of gamma-aminobutyric acid type A receptors (GABA_AR).
• Initially marketed as a safe sleeping aid, its recreational use surged.

Purpose of the Study:

• To review the comprehensive profile of methaqualone.
• To cover its discovery, history, and synthesis.
• To discuss its pharmacology, metabolism, and pharmacokinetics.

Main Methods:

• Literature review of methaqualone's history and effects.
• Analysis of pharmacological mechanisms.
• Examination of pharmacokinetic and metabolic data.

Main Results:

• Methaqualone's euphoric and sedative effects led to widespread recreational use.
• The drug's addictive potential became evident through misuse, overdoses, and dependence.
• Various methaqualone derivatives are produced in clandestine laboratories.

Conclusions:

• Methaqualone's history illustrates the evolution from a promoted medication to a drug of abuse.
• Understanding its pharmacology and pharmacokinetics is crucial due to its addictive nature.
• The continued illicit synthesis of derivatives poses ongoing public health concerns.
