Pilocarpine

Pilocarpine is a medication primarily used to treat glaucoma and dry mouth (xerostomia). It belongs to a class of drugs called cholinergic agonists, which work by stimulating certain glands and muscles. In glaucoma, Pilocarpine reduces intraocular pressure, preventing optic nerve damage. It is also prescribed for individuals with Sjögren's syndrome or those undergoing radiation therapy, as it helps increase saliva production. Available in various forms such as eye drops and oral tablets, Pilocarpine is an effective treatment for managing eye pressure and dry mouth conditions.

Uses of Pilocarpine

• Treatment of glaucoma by reducing intraocular pressure
• Management of dry mouth (xerostomia) due to Sjögren's syndrome
• Relieves dry mouth caused by radiation therapy
• Used in certain eye conditions requiring pupil constriction

How Pilocarpine Works

Pilocarpine is a cholinergic agonist that stimulates the parasympathetic nervous system. In glaucoma, it increases the drainage of aqueous humor from the eye, reducing intraocular pressure. When used for dry mouth, it stimulates the salivary glands to produce more saliva, alleviating discomfort and difficulty in swallowing.

Benefits of Pilocarpine

• Effectively reduces eye pressure in glaucoma patients
• Improves saliva production in dry mouth conditions
• Prevents optic nerve damage and vision loss
• Provides relief from discomfort caused by dry mouth
• Available in multiple forms for different conditions
