ANS Drugs
| Term | Definition |
|---|---|
| bethanechol (urecholine) | direct cholinergic: GI and urinary tract atony |
| carbamylcholine | direct cholinergic: treats atony of GI tract and stimulate uterine contractions in pigs |
| acetylcholine | direct cholinergic: rarely used due to fast breakdown by acetylcholinesterase |
| pilocarpine | direct cholinergic: reduces intraocular pressure associated with glaucoma |
| metochlopramide | direct cholinergic: control vomiting and reduce gastric tract emptying |
| edrophonium | indirect cholinergic: diagnose myasthenia gravis |
| neostigmine | indirect cholinergic: treat urine retention, GI atony, and as an antidote to neuromuscular blocking agents |
| physostigmine | indirect cholinergic: similar to neostigmine, urine retention, GI atony, and an antidote to neuromuscular blocking agents |
| organophosphate compounds | indirect cholinergic: insecticide dips, can result in toxicity |
| demecarium | indirect cholinergic: prevention management of glaucoma |
| pyridostigmine | indirect cholinergic: treatment of myasthenia gravis |
| atropine | cholinergic blocking: preanisthetic to dry secretions and prevent bradycardia, to counteract arganophosphate poisoning, dilate pupils for ophthalmic exams, control ciliary spasms of the eye, to treat sinus bradycardia, and to slow a hypermotile gut |
| methscopolamine | cholinergic blocking: control diarrhea |
| glycopyrrolate | cholinergic blocking: similar to atropine, provides longer duration of action, used primarily as anesthetic |
| aminopentamide | cholinergic blocking: control diarrhea and vomiting in dogs and cats |
| propantheline | cholinergic blocking: treat diarrhea, urinary incontinence, and bradycardia, to reduce colonic peristalisis in horses for rectal exams, similar to glycopyrrolate |
| pralidoxime | cholinergic blocking: treat organophosphate intoxication |
| epinephrine | adrenergic: increase in heart rate and cardiac output, constriction of blood vessels in skin and dilation of blood vessels in muscle, dilation of bronchioles, increase in metabolic rate |
| norepinephrine | adrenergic: raises blood pressure |
| isoproterenol | adrenergic: bronchodilation |
| phenylephrine | adrenergic: nasal vasocontrictor |
