Pyridostigmine bromide is recommended for symptom management in myasthenia gravis because it is an acetylcholinesterase inhibitor that improves neuromuscular transmission by increasing the availability of acetylcholine at the neuromuscular junction. In myasthenia gravis, the immune system produces antibodies that block or destroy nicotinic acetylcholine receptors, leading to muscle weakness and fatigue. By inhibiting the breakdown of acetylcholine, pyridostigmine enhances muscle contraction and increases strength in affected muscles, thus providing effective symptom relief.

Other medications listed, such as albuterol, are designed for different purposes, such as bronchodilation in asthma or COPD and are not indicated for myasthenia gravis management. Cortisol, a corticosteroid, may be used in some cases to help manage autoimmune responses but does not directly address the neuromuscular transmission issues associated with myasthenia gravis. Atropine is an anticholinergic medication that blocks acetylcholine receptors and would counteract the desired effects in this condition. Therefore, pyridostigmine bromide is the most appropriate choice for managing symptoms of myasthenia gravis.
