Which medication is typically prescribed for myasthenia gravis?

The medication typically prescribed for myasthenia gravis is prednisone. Myasthenia gravis is an autoimmune disorder characterized by weakness and rapid fatigue of voluntary muscles. The primary treatment strategy often includes improving muscle strength by modulating the immune response.

Prednisone, a corticosteroid, is effective in reducing inflammation and suppressing the immune system, which helps to alleviate the symptoms of myasthenia gravis. It works by inhibiting the actions of immune cells that mistakenly attack the body's own acetylcholine receptors, which are crucial for muscle contraction.

Other medications listed do not serve this purpose. Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation but does not address the underlying autoimmune aspect of myasthenia gravis. Anastrozole is primarily used as a treatment for breast cancer by inhibiting estrogen production. Bleomycin is an anticancer agent used for certain types of cancer and does not have a role in treating myasthenia gravis. Thus, the choice of prednisone is aligned with the treatment goals of managing this condition effectively.
