Myasthenia gravis is an autoimmune disease of the nervous system. Patients need to take medication for a long time, otherwise, antibodies to acetylcholine receptors might continue to be produced, further worsening the clinical manifestations. The medications taken by patients with myasthenia gravis mainly include the following types, the first being cholinesterase inhibitors. These drugs can inhibit the breakdown of acetylcholine by cholinesterase, thereby improving the transmission function between nerve and muscle junctions, and improving the clinical symptoms of patients. It is best to take these medications before meals for better absorption. The second type of medication mainly includes corticosteroids. They can suppress the body's immune response and reduce the production of antibodies, which is very helpful for the recovery from the disease. Long-term usage and gradual dosage reduction are necessary. Additionally, some immunosuppressants need to be taken. Taking these immunosuppressants also aims to suppress the immune response. However, it is essential to be aware of their adverse effects, such as suppression of bone marrow function, and damage to liver and kidney functions.
