Enhancement pharmacology is the study and use of drugs intended to improve functioning beyond the normal baseline in people without diagnosed deficits. It spans cognitive, physical, mood, and sensory domains and sits alongside therapeutic pharmacology, which aims to treat illness or restore function. Substances used for enhancement range from caffeine and other commonly used stimulants to prescription medications such as methylphenidate and amphetamines, wakefulness-promoting agents like modafinil, and various nootropic compounds. The intended effects, evidence base, and safety profiles vary considerably across substances and contexts.

Most agents act by modulating neurotransmitter systems including dopamine, norepinephrine, acetylcholine, or adenosine, among others. For some substances, robust evidence supports modest improvements in specific settings (for example, caffeine for alertness; modafinil in sleep-deprived individuals), while for many others evidence is limited or mixed, and risks include sleep disturbance, cardiovascular events, anxiety or dependence, and potential interactions with other medications.

Ethical and regulatory considerations include fairness and coercion in academic or professional settings, potential socio-economic inequities in access, and concerns about medicalization of normal variation. Many substances are regulated; some are prescription-only or prohibited in sport under anti-doping rules.

Research priorities focus on clarifying efficacy and safety, understanding individual differences in response, long-term effects, and how pharmacological approaches compare with non-pharmacological strategies such as adequate sleep, physical activity, and cognitive training.
