Here is a comprehensive overview of Pilocarpine Eye Drops 2%:
✅ DESCRIPTION
Pilocarpine Hydrochloride 2% Ophthalmic Solution is a cholinergic parasympathomimetic agent used primarily for reducing intraocular pressure (IOP) in patients with glaucoma or ocular hypertension. It works by stimulating the muscarinic receptors in the eye, causing miosis (pupil constriction) and improving aqueous humor outflow.
🧪 FORMULATION
- Active Ingredient: Pilocarpine Hydrochloride 2% (20 mg/mL)
- Preservative: Benzalkonium chloride
- Other Excipients:
- Sodium chloride
- Hydrochloric acid and/or sodium hydroxide (for pH adjustment)
- Purified water
- Form: Sterile ophthalmic solution
🌿 NATURE
- Type: Miotic agent / Muscarinic receptor agonist
- Mechanism of Action:
Stimulates muscarinic receptors → ciliary muscle contraction → opens trabecular meshwork → increases aqueous humor drainage → reduces IOP
💊 USES
- Primary Use:
- Primary open-angle glaucoma
- Acute angle-closure glaucoma (initial management)
- Ocular hypertension
- Other Uses:
- Induce miosis during eye surgery
- Counteracting mydriatic effects after eye exams
- Occasionally used for Adie’s pupil or neurologic pupillary defects
🌟 ADVANTAGES
- Effective IOP reduction
- Useful in narrow-angle and acute-angle closure glaucoma
- May prevent optic nerve damage in glaucoma
- Low systemic absorption if used properly
- Can be combined with other antiglaucoma drugs (e.g., timolol, dorzolamide)
⚠️ PRECAUTIONS
- Local Side Effects:
- Blurred or dim vision (especially in low light)
- Brow ache, headache (from ciliary muscle spasm)
- Eye irritation, burning or stinging
- Conjunctival redness
- Miosis (pupil constriction)
- Systemic Side Effects (rare):
- Sweating, increased salivation, bradycardia, or bronchospasm
(especially in overuse or absorption in children)
- Sweating, increased salivation, bradycardia, or bronchospasm
- Use with caution in:
- Patients with retinal detachment risk
- Uveitis or inflammatory eye disease
- Asthma or heart disease
- Night-time driving (due to poor night vision)
- Contact lens users: Remove lenses before use, wait at least 15 minutes before reinserting.
