What are the three functional classes of CNS stimulants? What do they do?
Amphetamines (amphetamine sulfate) - Increase the excitatory neurotransmitters (norepi & dopamine), treat drowsiness, fatigue, & suppress appetite.
Methylphenidates (Ritalin) - Most common drug for ADHD, similar MOA as amphetamines.
Methylxanthines (caffeine) - Block adenosine receptors, relax bronchial smooth muscle, similar to amphetamines with a much lesser effect.
