  5. 1. What Atropine Solution for injection is and what it is used for

Atropine belongs to a group of medicines called antimuscarinics. These medicines are often used in anaesthesia to reduce the flow of saliva and other body fluids. Atropine may also act on the vagus nerve (a nerve that sends information from the brain to other parts of the body). This helps to make the heart beat faster.

Atropine Injection is used to raise the heart rate if it has become too slow after a heart attack or to restart the heart.

Atropine Injection is also used to treat pesticide and mushroom poisoning and can be used as an antidote for overdose of cholinesterase inhibitors (a type of medicine usually used to treat the symptoms of Alzheimer’s disease).
