Polyethylene Glycol (0.4% w/v) + Propylene Glycol (0.3% w/v)
Price: ₹175 - ₹215 for pack of 10 single-dose vials (0.8ml each)
Mfr: Micro Labs Ltd. | Form: Eye Drops

📋 Clinical Overview

A sterile, preservative-free, topical ophthalmic solution combining two demulcent and lubricating agents. It is primarily used as an artificial tear substitute to relieve symptoms of dry eye disease (DED) by mimicking the properties of natural tears, providing lubrication, hydration, and protection to the ocular surface. The formulation is isotonic and has a pH compatible with the eye.

💊 Dosage & Administration

Adult: One or two drops in the affected eye(s) as needed, typically 4 to 6 times daily or as directed by a physician. Can be used more frequently in severe cases.

Note: 1. Wash hands before use. 2. Tilt head back. 3. Gently pull down lower eyelid to form a pouch. 4. Instill the drop(s) into the pouch without touching the dropper tip to the eye, eyelid, or any surface. 5. Close eyes gently for 1-2 minutes. Apply gentle pressure to the inner corner of the eye (nasolacrimal occlusion) to minimize systemic drainage. 6. For single-dose vials: use immediately after opening. Discard the vial after use, even if solution remains. Do not store for later use.

⚠️ Contraindications

  • Known hypersensitivity to Polyethylene Glycol, Propylene Glycol, or any component of the formulation.

🔬 Mechanism of Action

The combination acts synergistically to lubricate, protect, and hydrate the ocular surface. Polyethylene Glycol (PEG) 400 is a high-molecular-weight polymer that forms a hydrophilic film over the cornea, prolonging tear film breakup time (TBUT) and providing sustained lubrication. Propylene Glycol is a humectant and demulcent that binds water, helps stabilize the tear film lipid layer, and promotes epithelial healing.

🤕 Side Effects

  • Transient mild blurring of vision immediately after instillation
  • Mild, temporary ocular discomfort or stinging upon application

🤰 Special Populations

Pregnancy: Category C (US FDA). No adequate and well-controlled studies in pregnant women. Polyethylene glycol and propylene glycol are commonly used excipients. Use only if clearly needed and potential benefit justifies potential risk to the fetus. Topical ocular use with minimal systemic absorption presents low risk.

Driving: May cause transient blurring of vision after instillation. Patients should not drive or operate machinery until vision clears, which usually takes a few minutes.

🔄 Drug Interactions

Other topical ophthalmic medicationsMay dilute other eye drops if instilled simultaneously, reducing their efficacy.Moderate
Eye drops containing preservatives (e.g., Benzalkonium Chloride)This preservative-free formulation is often recommended to avoid the toxic effects of preservatives. Using preserved drops concurrently may negate this benefit.Mild
