SL-164 (other names dicloqualone, DSQ) is a new designer drug of the quinazolinone class, used as a sedative, anticonvulsant, as well as a sleeping pill. SL-164 was developed as a replacement for methaqualone, which was developed in the middle of the last century and was used as a sedative and hypnotic, but after strong popularity among young people and drug addicts, it was banned. SL-164 is used as a designer drug for chemical research in special private laboratories and has never been marketed as a medicine and had no use in medicine.
