1. What Atropine Injection is and what it is
used for
Atropine belongs to a group of medicines called

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 as a result of taking
beta-blocker drugs.
Atropine is also used to reduce fluid in the lungs during
general anaesthesia.
