Here is a comprehensive overview of Homatropine Eye Drops 2%:
💧 Homatropine Hydrobromide Ophthalmic Solution 2%
✅ DESCRIPTION
Homatropine 2% Eye Drops is a short-acting anticholinergic agent used to produce mydriasis (pupil dilation) and cycloplegia (temporary paralysis of accommodation). It is typically used in the treatment of uveitis and for diagnostic eye examinations.
🧪 FORMULATION
- Active Ingredient: Homatropine Hydrobromide 2% (20 mg/mL)
- Preservative: Benzalkonium chloride (usually 0.01%)
- Other Excipients:
- Sodium chloride
- Hydrochloric acid / Sodium hydroxide (for pH adjustment)
- Purified water
- Form: Sterile ophthalmic solution
🌿 NATURE
- Class: Anticholinergic / Muscarinic receptor antagonist
- Type: Mydriatic / Cycloplegic
- Mechanism of Action:
Blocks muscarinic receptors in the iris sphincter and ciliary muscle → causes pupil dilation and relaxes accommodation → reduces pain and prevents synechiae in uveitis
💊 USES
- Therapeutic Uses:
- Uveitis / Iritis: to relieve pain, prevent posterior synechiae
- Post-operative inflammation
- Diagnostic Uses:
- Cycloplegic refraction testing in children and adults
- Mydriasis for fundus examination (when longer action is acceptable)
🌟 ADVANTAGES
- Shorter duration of action than atropine (typically 12–24 hours)
- Effective in managing anterior uveitis
- Produces pupil dilation and pain relief
- Safer for diagnostic use compared to longer-acting agents
- Can be used in children and adults
