Which of the following is not given in myasthenia gravis :
**Core Concept**
Myasthenia gravis is an autoimmune disease characterized by the production of antibodies against acetylcholine receptors at the neuromuscular junction, leading to muscle weakness and fatigue. The treatment aims to increase acetylcholine availability, block the action of autoantibodies, or enhance neuromuscular transmission.
**Why the Correct Answer is Right**
The correct treatment options for myasthenia gravis include:
* **Option A:** Pyridostigmine (a cholinesterase inhibitor that increases acetylcholine availability)
* **Option B:** Corticosteroids (to reduce inflammation and suppress autoantibody production)
* **Option C:** Azathioprine (an immunosuppressive agent that reduces autoantibody production)
* **Option D:** All of the above treatments are commonly used in myasthenia gravis management.
However, the correct answer is actually an option that is not typically given in myasthenia gravis. Let's identify the incorrect option.
