Study Notes
Cholinergic Receptors
- M- and H- cholinergic receptors are stimulated by pilocarpine, aceclidine, and carbacholine.
- Prozerin is an anticholinesterase drug used for glaucoma.
Effects of Acetylcholine
- Increased secretion of sweat glands occurs under the influence of acetylcholine.
- Mydriasis, increased intraocular pressure, paralysis of accommodation, and tachycardia are effects of acetylcholine.
Anticholinesterase Agents
- Physostigmine and galantamine are anticholinesterase agents.
- Edrophonium is an anticholinesterase agent used as an antidepolarizing antagonist muscle relaxant.
Cholinomimetic Agents
- Carbacholine is used for glaucoma and blocks M- cholinergic receptors.
- Aceclidine is a cholinomimetic agent that blocks H- cholinergic receptors.
Adrenergic Receptors
- Beta-1 adrenergic receptors of the heart are stimulated, leading to increased strength of heart contractions, decreased heart rate, and difficulty in atrioventricular conduction.
Adrenergic Agonists
- Adrenalin stimulates alpha and beta adrenergic receptors.
- Terbutaline, dobutamine, and norepinephrine are adrenergic agonists.
- Ephedrine is a sympathomimetic that stimulates alpha and beta adrenergic receptors.
Alpha- and Beta-Adrenergic Receptor Blockers
- Labetalol and carvedilol are alpha- and beta-adrenergic receptor blockers.
Anesthetics
- Propofol, anesthesin, morphine, and trimecaine are anesthetics.
- Thiopental-sodium is a short-acting anesthetic.
- Hexenal is an anesthetic administered by inhalation.
Psychostimulants
- Pyridrol, codeine, bemegrid, piracetam, and amitriptyline are psychostimulants.
- Sydnocarb is a psychostimulant from the sydnonimine group.
Antidepressants
- Amitriptyline, diazepam (sibazon), phenazepam, and phenamine are antidepressants.
- Nialamide and imizin are antidepressant monoamine oxidase inhibitors.
This quiz assesses knowledge of cholinergic receptors and related pharmacological agents. Topics include M- and H-receptors and specific drugs that stimulate or inhibit them.
