General Description
Atropine sulfate (Atropisol)is prepared by neutralizing atropine in acetone or ethersolution with an alcoholic solution of sulfuric acid, withcare used to prevent hydrolysis. The salt occurs as colorlesscrystals or as a white, crystalline powder. It is efflorescentin dry air and should be protected from light to preventdecomposition.Atropine sulfate is freely soluble in water (1:0.5), in alcohol(1:5, 1:2.5 at boiling point), and in glycerin (1:2.5).Aqueous solutions are not very stable, although solutionsmay be sterilized at 120°C (15 lb pressure) in an autoclave if the pH is kept below 6. Sterilization probably is besteffected by the use of aseptic techniques and a bacteriologicalfilter. It has been suggested that no more than a 30-daysupply of an aqueous solution should be made and that forsmall quantities the best procedure is to use hypodermictablets and sterile distilled water. Kondritzer andZvirblis have studied the kinetics of alkaline and protoncatalyzedhydrolyses of atropine in aqueous solution. Theregion of maximal stability lies between pH 3 and approximately5. They have also proposed an equation to predictthe half-life of atropine undergoing hydrolysis at constantpH and temperature.
Clinical Use
Atropine may be used to treat some types of arrhythmias. Itincreases the heart rate by blocking the effects of ACh on thevagus. In this context, it is used to treat certain reversible bradyarrhythmiasthat may accompany acute myocardial infarction.It is also used as an adjunct to anesthesia to protect againstbradycardia, hypotension, and even cardiac arrest induced bythe skeletal muscle relaxant succinylcholine chloride.Another use for atropine sulfate emerged following thedevelopment of the organophosphates, which are potent inhibitorsof AChE. Atropine is a specific antidote to preventthe muscarinic effects of ACh accumulation, such as vomiting,abdominal cramps, diarrhea, salivation, sweating, bronchoconstriction,and excessive bronchial secretions. It isused intravenously but does not protect against respiratoryfailure caused by depression of the respiratory center andthe muscles of respiration.
Safety Profile
Poison by
subcutaneous, intravenous, and
intraperitoneal routes. Moderately toxic by
ingestion. Human (child) pulmonary system
effects by ingestion. Human systemic
effects: decreased body temperature, cardiac
arrhythmias. An experimental teratogen.
Other experimental reproductive effects. See
also ATROPINE. When heated to
decomposition it emits very toxic fumes of
NO,xand SOx.
Veterinary Drugs and Treatments
The principal veterinary indications for systemic atropine include:
!!Preanesthetic to prevent or reduce secretions of the respiratory
tract
!!Treat sinus bradycardia, sinoatrial arrest, and incomplete AV
block
!!Differentiate vagally-mediated bradycardia for other causes
!!As an antidote for overdoses of cholinergic agents (e.g., physostigmine,
etc.)
!!As an antidote for organophosphate, carbamate, muscarinic
mushroom, blue-green algae intoxication
!!Hypersialism
!!Treatment of bronchoconstrictive disease
Check Digit Verification of cas no
The CAS Registry Mumber 55-48-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55-48:
(4*5)+(3*5)+(2*4)+(1*8)=51
51 % 10 = 1
So 55-48-1 is a valid CAS Registry Number.

The invention provides a synchronizing method of atropine sulphate. The method is characterized in that hydrolyzing methyl phenoxyacetate (II) is hydrolyzed to obtain a compound (III); the compound (III) and thionyl chloride are subjected to acylation reaction to obtain a compound (IV); the compound (IV) and 8-methyl-8-azabicyclo[3.2.1]oct-3-alchol are subjected to condensation reaction to obtain a compound (V); the compound (V) and paraformaldehyde are used for producing atropine (VI) under an alkaline condition; the atropine (VI) is salified under an acidic condition to obtain the atropine sulphate (I). The preparation method is simple in technology, high in yield, high in purity, low in monomer impurity and easy for industrial production.
