{{/items}} {{^items}}Description
An alkaloid, originally from Atropa belladonna, but found in other plants, mainly solanaceae. [PubChem]
Indication
For the treatment of poisoning by susceptible organophosphorous nerve agents having anti-cholinesterase activity (cholinesterase inhibitors) as well as organophosphorous or carbamate insecticides.
Mechanism of Action
Atropine binds to and inhibit muscarinic acetylcholine receptors, producing a wide range of anticholinergic effects.
Pharmacokinetics
- Absorption
- Atropine is rapidly and well absorbed after intramuscular administration. Atropine disappears rapidly from the blood and is distributed throughout the various body tissues and fluids.
- Distribution
- Metabolism
- Much of the drug is destroyed by enzymatic hydrolysis, particularly in the liver. From 13 to 50% is excreted unchanged in the urine.
- Elimination
Toxicity
Oral, mouse: LD50 = 75 mg/kg. Symptoms of overdose includes widespread paralysis of parasympathetically innervated organs. Dry mucous membranes, widely dilated and nonresponsive pupils, tachycardia, fever and cutaneous flush are especially prominent, as are mental and neurological symptoms. In instances of severe intoxication, respiratory depression, coma, circulatory collapse and death may occur.

Description
A meperidine congener used as an antidiarrheal, usually in combination with atropine. At high doses, it acts like morphine. Its unesterified metabolite difenoxin has similar properties and is used similarly. It has little or no analgesic activity. This medication is classified as a Schedule V under the Controlled Substances Act by the Food and Drug Administration (FDA) and the DEA in the United States when used in preparations. When diphenoxylate is used alone, it is classified as a Schedule II.
Indication
For as adjunctive therapy in the management of diarrhea
Mechanism of Action
Diphenoxylate is an opiate receptor agonists that stimulate mu receptors in GI to decrease the peristalsis and constrict the sphincters. Diphenoxylate has a direct effect on circular smooth muscle of the bowel, that conceivably results in segmentation and prolongation of gastrointestinal transit time. The clinical antidiarrheal action of diphenoxylate may thus be a consequence of enhanced segmentation that allows increased contact of the intraluminal contents with the intestinal mucosa.
