Safety A human poison by an unspecified route. Poison experimentally by ingestion, subcutaneous, intramuscular, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: nausea, dyspnea, coma, blood pressure elevation, flaccid paralysis without anesthesia, muscle weakness. Normally administered by injection. Poisoning can occur as a result of a mistake in dosage or due to hypersensitivity of the patient within 5 to 25 minutes after administration. Death usually results from respiratory paralysis. Experimental reproductive effects. Combustible when exposed to heat or flame. When heated to decomposition it emits toxic fumes of NOx. See also CARBAMATES. Risk Codes 26/28

PHYSOSTIGMINE Specification

1.General Description :White, odorless, microcrystalline powder. Used as a cholinergic (anticholinesterase) agent and as a veterinary medication.
2.Health Hazard :Super toxic. Probable oral lethal dose is less than 5 mg/kg for a 70 kg (150 lb.) person. Material is a cholinesterase inhibitor. Effects of exposure may involve the respiratory, gastrointestinal, cardiovascular and central nervous systems. Death occurs due to respiratory paralysis or impaired cardiac function. Time to death may vary from 5 minutes to 24 hours, in severely poisoned patients, depending on factors such as the dose and route. Persons with asthma and/or persons that require drugs containing choline esters are at risk.
3.Fire Hazard : Physostigmine (CAS NO.57-47-6) is a slight fire hazard. When heated to decomposition Physostigmine emits toxic fumes of nitrogen oxides. Keep from light and heat.
