Pystig 180 SR Tablet is used to treat myasthenia gravis (muscle weakness). Besides this, Pystig 180 SR Tablet also treats paralytic ileus (a rare form of constipation), postoperative urinary retention, and prophylaxis to military exposure to any nerve poisoning gas. Myasthenia gravis is a long-term neuromuscular disease that leads to musculoskeletal weakness caused by excess activity of a protein (cholinesterase protein).

Pystig 180 SR Tablet contains ‘Pyridostigmine’, which works by stopping the excessive cholinesterase activity (an enzyme required for the breakdown of a neurotransmitter called acetylcholine) involved in communication between nerve impulses and muscle movements. Thereby, Pystig 180 SR Tablet helps in proper muscle functioning and prevents muscle weakness. 

Take Pystig 180 SR Tablet 30-60 minutes before food. Swallow Pystig 180 SR Tablet as a whole; do not crush or chew the tablet. You are advised to take Pystig 180 SR Tablet as long as your doctor has prescribed it for you, depending on your medical condition.

Pystig 180 SR Tablet belongs to the group of medicines called cholinesterase inhibitors used to treat myasthenia gravis (muscle weakness). Pystig 180 SR Tablet works by stopping the excessive activity of cholinesterase, thus helping the muscles to work properly. Additionally, Pystig 180 SR Tablet is also used to treat paralytic ileus (a rare form of constipation), postoperative urinary retention, and prophylaxis to soman nerve agent poisoning. Pystig 180 SR Tablet affects the chemicals in the body which are involved in communication between nerve impulses and muscle movements. Thereby, Pystig 180 SR Tablet helps in treating myasthenia gravis.

• Maintain a healthy weight. Include vegetables, fruits and grains in your diet.
• Diet low in fat, saturated fat and cholesterol would be helpful.
• Use salt and sugars in moderation.
• Avoid consumption of alcohol.

Myasthenia gravis: It is an autoimmune neuromuscular disease which causes skeletal muscle weakness. The immune system mistakenly attacks its own healthy tissue, leading to damage of the neuromuscular membrane. This reduces the effect of acetylcholine, a neurotransmitter which is crucial for the communication between nerve cells and muscles. Myasthenia gravis occurs when the communication between nerve cells and muscles becomes impaired. This prevents crucial muscle contractions, thereby leading to muscle weakness. The most affected muscles are those of the face and eyes. Symptoms of myasthenia gravis include double vision, drooping eyelids, difficulty chewing or swallowing, weakness, problems with lifting objects, and trouble talking and walking.

Paralytic ileus: It is a condition in which there is obstruction of the intestine due to paralysis of intestinal muscles. This prevents the passage of food and leads to their accumulation in the intestine. Paralytic ileus occurs due to malfunctioning of nerves and muscles in the intestine, thereby impairing digestive movement.
