Special
Considerations: Drugs Affecting the Central Nervous System
Psychoactive
drugs have an effect on the brain and are among the most frequent medications
given to the elderly. Elderly patients generally require lower doses of
psychoactive drugs, in some cases one-fourth to one-half the dose of a
younger patient.3
Examples
of Psychoactive Drugs:
Anti-psychotics
Anti-anxiety drugs
Sedatives/hypnotics
Anti-depressants
Psychoactive drugs are not the only type of medication that can produce
dangerous side effects. Drugs that relieve pain (analgesics), drugs that act
on the heart and blood vessels (cardiovascular drugs), drugs that relieve
nausea (anti-emetics), and drugs that relieve allergies (antihistamines) also
have the potential to produce negative side effects by acting on the brain.
