Final answer:
Desoxyn falls under the CNS Stimulant category. It is a stimulant drug that increases brain activity, unlike depressants that calm the brain. Desoxyn is primarily used for ADHD and obesity treatment.
Step-by-step explanation:
Desoxyn is a drug of the CNS Stimulant DRE drug category. Desoxyn, known generically as methamphetamine, is a central nervous system (CNS) stimulant that is used primarily to treat attention deficit hyperactivity disorder (ADHD) and obesity. CNS stimulants like Desoxyn increase mental and/or physical functions and are often referred to as "uppers" because they elevate levels of arousal and activity in the brain.
Unlike depressants, which calm the brain and can induce feelings of relaxation, stimulants create heightened alertness. Depressants generally serve as agonists of the gamma-Aminobutyric acid (GABA) neurotransmitter system, which has a quieting effect on the brain. In contrast, stimulants such as Desoxyn agonize dopamine neurotransmission, leading to increased wakefulness and mental focus.
