Edrophonium (Tensilon) test is used to diagnose myasthenia gravis. A positive test result, indicating the presence of myasthenia gravis, would show an increase in muscle strength within 1 to 3 minutes after administration of the medication. This occurs because edrophonium temporarily inhibits the breakdown of acetylcholine, thereby increasing its availability at the neuromuscular junction and improving muscle strength.
