Obtained as a syrup from plants of the Solanaceae family. Intensely poisonous, its action resembles that of atropine. Sedative in small doses.

Environmental. The A/-methylcarbamates generally are biodegradable and of low soil persistence with half-Hves for carbaryl and aldicarb of 1—2 weeks and of carbofuran of 1—4 months. Certain carbamates are highly toxic to birds with oral LD qS for mallard, eg, pheasant, in mg/kg carbofuran, 0.40, 4.2 mexacarbate, 3.0, 4.5 and methomyl, 16, 15 compared to carbaryl >2000. Fish toxicity of carbamates is generally low, but these compounds are extremely toxic to bees. In cases of human poisoning, atropine is a specific antidote. 

Dialkylphosphorochloridates, (R0)2P(=0)C1, react with trialkyl phosphate esters to give organic pyrophosphates. Organopyrophosphates are anticholinesterase agents and should be handled with great caution (16). Atropine sulfate is a specific antidote. 

At this writing anticholinergic agents are not widely used for the symptomatic treatment of asthma, although compounds such as atropine [51 -55-8] C17H23NO3, (18) have been used for centuries (111). Inhalation of the smoke produced by burning herbal mixtures, such as Datura Stramonium provided bronchodilation and rehef from some of the symptoms of asthma. The major active component in these preparations was atropine or other closely related alkaloids (qv). 

Atropine is weU absorbed orally and can be adrninistered parenteraHy. About 50% of an adrninistered dose is metabolized in the Hver, the rest is excreted in the urine unchanged. About 77—94% of an adrninistered dose is excreted in the urine. The pharmacological half-life of atropine is about 2—3 h... 

Adverse effects with atropine therapy include dry mouth, myosis, loss of visual accommodations, constipation, and urinary retention. The dmg can also produce flushing, hyperthermia, delirium, tachycardia, and exacerbate glaucoma (85). 

Isoproterenol. Isoproterenol hydrochloride is an nonselective P-adrenoceptor agonist that is chemically related to NE. It mimics the effects of stimulation of the sympathetic innervation to the heart which are mediated by NE. It increases heart rate by increasing automaticity of the SA and AV nodes by increasing the rate of phase 4 diastoHc depolarization. It is used in the treatment of acute heart block and supraventricular bradyarrhythmias, although use of atropine is safer for bradyarrhythmias foUowing MI (86). 

Agent BZ, 3-quinuchdinylbenzilate [6581 -06-2] C22H23NO2, is a typical incapacitant. BZ is one of a group of substances, many of them glycolate esters, sometimes known as atropinemimetics. Their action on the central and peripheral nervous systems resembles that of atropine [51-55-8] ... 

Immediate treatment of an exposed individual is essential. The U.S. regimen includes the pretreatment, and after exposure atropine and 2-PAM are self-adininistered. Eurther treatment includes up to two additional doses, followed by the tranquilizer VaHum. As required, artificial respiration is instituted, clearing the airway if necessary. The current standard U.S. Army atropine item is the automatic injector, Atropen, designed for self-adininistration by the individual in the field.
