Mestinon, containing pyridostigmine, improves communication between nerves and muscles. It achieves this by inhibiting acetylcholinesterase, an enzyme that breaks down acetylcholine. Acetylcholine is a neurotransmitter crucial for muscle contraction.
Increased Acetylcholine Levels
By blocking acetylcholinesterase, Mestinon increases the amount of acetylcholine available at neuromuscular junctions. This heightened availability allows for stronger and more frequent muscle contractions.
Improved Muscle Function
The result is improved muscle strength and control. This directly combats the weakness and fatigue experienced by individuals with conditions like myasthenia gravis, where the body’s immune system attacks acetylcholine receptors.
Dosage and Administration
Note: Dosage varies greatly depending on individual needs and should always be determined by a physician. Mestinon is typically administered orally but can be given intravenously in specific situations.
Potential Side Effects
Important: While Mestinon helps many, it can cause side effects such as nausea, diarrhea, and abdominal cramps. More serious, though less common, side effects include breathing problems and slowing of the heart rate. Consult your doctor immediately if you experience any concerning symptoms.
