Dexamyl is not still available as Dexamyl was discontinued by SKF in 1982.
Dexamyl is a combination drug that contains dextroamphetamine and amobarbital.
The reason why Dexamyl is discontinued is because it was widely and highly abused and so it's no longer manufactured.
The discontinuation that occurred of dexamyl also occurred as a result of the development of monoamine oxidase inhibitors and tricyclic antidepressants, which also shared similar treatment indications with Dexamyl although it also had a lower dependence and abuse potential.
Dexamyl is a combination medication containing dextroamphetamine and amylbarbitone, was marketed as an anorectic (appetite suppressant), anxiolytic (anxiety-reducing), and antidepressant.
