ACRIS 25MG INJECTION 2.5ML belongs to the group of medicines called skeletal muscle relaxants used to reduce and relieve the muscle spasms (excessive tension in the muscles) occurring during surgery in intensive care. Muscle spasm is the sudden involuntary contractions of the muscle, which can be painful and uncomfortable. When the nerve impulses that control the muscle movements are damaged or interrupted, it could lead to muscle spasms. ACRIS 25MG INJECTION 2.5ML contains ‘Atracurium’ that works by blocking the action of acetylcholine on skeletal muscles. Thus, stop sending a pain signal to the brain, thereby relieving muscle stiffness or muscle spasm along with pain and surgery. ACRIS 25MG INJECTION 2.5ML is used during surgery. It is also used during general anaesthesia to ease tracheal intubation (a tube into the windpipe) and controlled ventilation.
