Study Notes
- Lecture on sedative and hypnotic drugs in clinical practice covers benzodiazepines, barbiturates, and atypical drugs used in various scenarios.
- Benzodiazepines like diazepam and flurazepam are commonly used sedatives, with the latter known for clinical practice.
- Benzodiazepines can accumulate over days, requiring caution in daily use.
- Atypical drugs like lorazepam and oxazepam do not form active metabolites and are used clinically.
- Barbiturates like secobarbital and phenobarbital, the latter used in epilepsy, are extensively metabolized in the liver.
- Unclassified drugs metabolized rapidly by liver enzymes with shorter duration of action, mainly used as sleep aids.
- Dose-response curve shows sedation, anxiolysis with low doses, hypnosis with higher doses, and anesthesia where benzodiazepines peak while barbiturates show increasing toxicity.
- Benzodiazepines are preferred for anxiolysis, newer drugs have flatter curves indicating efficacy.
- Antiseizure activity found in benzodiazepines and barbiturates at different dose levels.
- Benzodiazepines induce sleep, reduce rapid eye movement (REM) sleep, leading to REM rebound upon cessation.
- Newer agents like zopiclone for insomnia show fewer side effects and rapid onset of action.
- Benzodiazepines suitable for short-term sedation, barbiturates more common for long-term anesthesia induction.
- Barbiturates induce medullary depression and coma, leading to respiratory arrest, low blood pressure, cardiovascular collapse, and potential death.
