Pyridostigmine bromide is available as a generic medication. It is marketed under various brand names, including Mestinon [1].
When did pyridostigmine bromide go off-patent?
The original patent for pyridostigmine bromide has long expired, allowing for generic versions to be manufactured and sold [2].
What conditions is pyridostigmine bromide used to treat?
Pyridostigmine bromide is primarily used to treat myasthenia gravis, a neuromuscular disorder that causes weakness in the voluntary muscles. It can also be used as an antidote for nerve agent poisoning and as a prophylactic agent against nerve agents [3].
How does pyridostigmine bromide work?
Pyridostigmine bromide is a reversible cholinesterase inhibitor. It works by preventing the breakdown of acetylcholine, a neurotransmitter, at the neuromuscular junction. This increases the concentration of acetylcholine, which then binds to muscle receptors, improving muscle strength and reducing weakness in individuals with myasthenia gravis [3].
Who makes generic pyridostigmine bromide?
Multiple pharmaceutical companies manufacture generic versions of pyridostigmine bromide. These include companies like Teva Pharmaceuticals, ANI Pharmaceuticals, and Amneal Pharmaceuticals, among others [1].
What are the potential side effects of pyridostigmine bromide?

How does generic pyridostigmine bromide compare to brand-name Mestinon?
Generic and brand-name medications contain the same active ingredient and are required to meet the same standards for quality, strength, and purity. Therefore, generic pyridostigmine bromide is therapeutically equivalent to brand-name Mestinon [4].
What is the cost of generic pyridostigmine bromide?
The cost of generic pyridostigmine bromide can vary depending on the manufacturer, dosage, and pharmacy. Generally, generic medications are significantly less expensive than their brand-name counterparts [5].
