Study Notes
Sedative-Hypnotic Drugs
- Drugs that induce sedation or sleep and relieve anxiety.
- Primarily used for anxiety and insomnia treatment.
- Classified based on clinical uses rather than chemical structures.
- Sedatives include benzodiazepines and buspirone.
- Hypnotics include barbiturates, ramelteon, and chloral hydrate.
Benzodiazepines
- Have a higher margin of safety compared to barbiturates.
- Therapeutic actions are similar, but vary in lipid solubility, metabolism, and half-life.
Classification
- Short acting (half-life < 5h): midazolam, triazolam
- Intermediate acting (half-life 5-24h): alprazolam, lorazepam, clonazepam
- Long acting (half-life > 24h): diazepam, clorazepate, flurazepam
Pharmacokinetics
- Good and rapid oral absorption.
- Lipid-soluble drugs (midazolam, triazolam) have a fast onset of action.
- Long-acting drugs, like diazepam, are metabolized by oxidation (CYP450) into active metabolites.
- Short-acting drugs are metabolized by conjugation into inactive metabolites for renal clearance.
- Lorazepam and oxazepam (metabolized extrahepatically) are preferred in liver dysfunction to avoid excessive CNS depression.
Mechanism of Action
- Benzodiazepines act on specific receptors in the CNS and peripheral tissues.
- Cause allosteric modulation of GABA action on GABAA receptors, increasing Cl- conductance and resulting in hyperpolarization.
- Six receptor subtypes identified; subtype 1 mediates most effects.
Pharmacological Effects
- Reduction of anxiety with small doses (anxiolytic effect).
- High doses induce hypnosedative effects.
- Central skeletal muscle relaxation useful for alleviating muscle tension and headaches.
