Include such drugs as barbiturates, methaqualone (Quaaludes), and tranquilizers such as Valium, Librium, Equanil, Meprobamate, Xanax, etc.

The effects of depressants are in many ways similar to the effects of alcohol. Small amounts can produce calmness and relaxed muscles, but somewhat larger doses can cause slurred speech, staggering gait, and altered perception. Very large doses can cause respiratory depression, coma, and death. The combination of depressants and alcohol can multiply the effects of the drugs, thereby multiplying the risks. The use of depressants can cause both physical and psychological dependence. Regular use over time may result in a tolerance to the drug, leading the user to increase the quantity consumed. When regular users suddenly stop taking large doses, they may develop withdrawal symptoms ranging from restlessness, insomnia, and anxiety, to convulsions and death. Babies born to mothers who abuse depressants during pregnancy may be physically dependent on the drugs and show withdrawal symptoms shortly after they are born. Birth defects and behavioral problems also may result.

Methaqualone

Methaqualone

Methaqualone (MQ, 470), 2-methyl-3-(2-methylphenyl)quinazolin-4(3H)-one, an hypnotic and anticonvulsive drug, is one of the leading examples of atropisomeric six-membered N-aryl heterocycles.

Methaqualone

Christopher P. Holstege, in Encyclopedia of Toxicology (Second Edition), 2005

Clinical Management

Basic and advanced life-support measures should be implemented as necessary. Gastrointestinal decontamination procedures should be used as appropriate based on the patient's level of consciousness and history of ingestion. Activated charcoal can be used to adsorb methaqualone. The patient's level of consciousness and vital signs should be monitored closely. Obtunded patients with reduced gag reflex should be intubated to prevent pulmonary aspiration. Respiratory support, including oxygen and ventilation, should be provided as needed. If hypotension occurs it should be treated with standard measures including intravenous fluids, Trendelenburg positioning, and dopamine by intravenous infusion. Forced diuresis, hemoperfusion, and hemodialysis are of no value in methaqualone toxicity. Seizures should be treated with benzodiazepines. Coagulation studies and platelet counts should be obtained. If withdrawal signs and symptoms develop, treatment should consist of benzodiazepine therapy with a gradual dose reduction.

Methaqualone and Meclaqualone

Methaqualone was first synthesized in 1951 and introduced as a new drug that produced sedation and sleep in 1956. Methaqualone has been initially designed to counter the nervous damages caused by long-term consumption and to reduce the risk of the dependency potential of barbiturates. Interest in methaqualone rose dramatically in recent years. Its popularity was due to its undeserved reputation as an ‘aphrodisiac’ often in combination with diphenhydramine. Because of its strong habit-forming properties the drug was placed in the list of controlled substances and the legal manufacturer stopped its production and removed it from the market in 1984.

Methaqualone and meclaqualone were prepared as nonbarbiturate sleeping tablets, though they have also legally been used as hypnotics in some European countries. They appear on the illicit drug market either through diversion from the legitimate pharmaceutical trade or through illicit synthesis. The illicit samples are usually brown or gray powders with varying degrees of purity. Methaqualone is also used sometimes as a cutting agent for heroin.

6.6.2 Methaqualone

Methaqualone (2-methyl-3-o-tolyl-4(3H)-quinazolinone; Fig. 6.8) is a powerful sedative, which was widely used. It has a high potential for addiction and was therefore scheduled. Since modern sedative–hypnotics such as benzodiazepines or benzodiazepine BZ1 (omega 1) receptor agonists such as zopiclone, zaleplon or zolpidem show much less toxicity, its use in pharmacotherapy has decreased. Since methaqualone is relatively stable and since it shows favorable LC and GC properties, it has become a very widely used internal standard for GC and LC determinations of many different classes of analytes [350,444–448].

Relatively few papers on detection of methaqualone were published in the 1990s. In two papers, the use of immunoassays for methaqualone detection was described. Klinger et al. [449] proposed the addition of two volumes of N,N-dimethylformamide to serum, plasma, and postmortem blood with subsequent centrifugation. The resulting supernatant could be directly analyzed by EMIT® d.a.u.® urine reagents [449]. Brenner et al. [450] compared immunoassay and GC-MS results prior to and after cleavage of conjugates. They concluded, that the immunoassays cross-reacted with the conjugated hydroxy metabolites. Since the biggest part of the hydroxy metabolites is excreted as conjugates, cleavage of conjugates was necessary before GC-MS analysis [450].

Methaqualone makes no great demands on the analytical techniques. Different liquid–liquid and SPEs are described and they work quite well. Usual RP-LC and GC systems are suitable for separation. UV-DAD or, even better, MS detection is recommended. Several screening procedures using LC-DAD [384,389,451,452] or using GC-MS [17,48] cover besides other analytes the detection of methaqualone.

Since methaqualone reaches high concentrations in biomatrices, detection and quantification of methaqualone in urine, blood and gastric content using CE was possible [453]. Assessment of the stereoselective metabolism of methaqualone was successfully done by CE [454,455]. For determination in hair GC-MS was preferred [453].

Six-membered Rings with Two Heteroatoms, and their Fused Carbocyclic Derivatives

Tao Cao, ... Jian Jin, in Comprehensive Heterocyclic Chemistry IV, 2022

8.02.12.2.4 Other activities

One of the most infamous quinazolinone derivatives is methaqualone (Fig. 19), also referred to as “Quaalude”. Methaqualone is a powerful sedative and hypnotic drug that was initially indicated in the treatment of insomnia, but was largely abused as a recreational drug in the 1960s and 1970s. Recent work has elucidated that methaqualone exerts its sedative effects by selective modulation of diverse subtypes of the GABAA receptor, with binding modes that are distinct from those of other known drugs that interact with this, such as benzodiazepines and barbiturates.637
