Return of the Quaaludes? Prolonged agitated delirium after intentional ingestion of the methaqualone analog SL-164 - a case report
Subst Abus 2021;42(4):503-505.PMID:33760714DOI:10.1080/08897077.2021.1903648.
Background: A 22-year-old male with a known history of drug abuse presented to our department with prolonged agitated delirium, myocloni, tachycardia and subfebrile temperature after the deliberate ingestion of opium poppy tea (Papaver somniferum L.) together with the methaqualone analog SL-164 (5-chloro-3-(4-chloro-2-methylphenyl)-2-methyl-4(3H)-quinazolinone) which is sold online as a designer drug. Methods: SL-164 and its hydroxy metabolites were detected in serum and urine via liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS). Results: The pronounced delirium was treated with benzodiazepines and neuroleptics; temporary medical restraint had to be applied. Symptoms completely resolved over the next 72 h and the patient was discharged on day three able to give consent. Conclusions: Although methaqualone was a popular and widespread sedative in the 1950s and 60 s before its discontinuation in the USA in 1985, derivatives of the methaqualone class have not previously played a large role as drugs of abuse in the rapidly growing market of new psychoactive substances. To our knowledge, this is the first case of agitated delirium with detection of SL-164 and hydroxylated metabolites in a patient's serum and urine.
Qua-Alluding to the Past: A Case of Methaqualone Analog Ingestion
J Anal Toxicol 2021 Sep 21;bkab103.PMID:34545408DOI:10.1093/jat/bkab103.
Methaqualone, known previously under the brand name Quaalude, is a Schedule I sedative hypnotic drug that may cause neurotoxicity in overdose, characterized by somnolence, hyperreflexia and muscular hyperactivity. We present a case of a 21-year-old male who reportedly ingested methaqualone in addition to insufflation of street cocaine. He subsequently developed hypoxia, hyperreflexia, myoclonus, and altered mental status. His laboratory results were notable for the presence of methemoglobinemia, which was most likely due to a cocaine contaminant. Laboratory analysis of the alleged methaqualone pills identified the substance as SL-164, a dichlorinated methaqualone analog. Urine toxicology results were positive for SL-164 (and presumed metabolites) as well as for cocaine and tetrahydrocannabinol metabolites. The patient was treated with supplemental oxygen and a benzodiazepine (lorazepam) and observed in the Emergency Department (ED) until his symptoms resolved. This case highlights current community access to methaqualone analogs. The case also focuses on laboratory techniques used to identify the methaqualone analog.
