Latanoprost/Timolol Polpharma (Latanoprost, Timolol)

• Latanoprost/Timolol is used in ophthalmology to lower intra‑ocular pressure by targeting the prostaglandin and beta‑adrenergic pathways.
• Open‑angle glaucoma: reduces intra‑ocular pressure to slow disease progression.
• Ocular hypertension: lowers eye pressure to prevent conversion to glaucoma.
• Secondary open‑angle glaucoma: provides additional pressure‑lowering effect when monotherapy is insufficient.

• Latanoprost activates prostaglandin F receptors in the ciliary body, increasing uveoscleral outflow of aqueous humor. Timolol non‑selectively blocks β‑adrenergic receptors in the ciliary epithelium, decreasing aqueous humor production. The combined actions result in a net reduction of intra‑ocular pressure, helping to preserve optic nerve function.

The following adverse reactions have been reported with the combination of latanoprost and timolol.

Common Side Effects

• Eye irritation or burning sensation.
• Transient blurred vision after instillation.
• Conjunctival hyperemia (redness).
• Increased eyelash growth.
• Darkening of the iris or peri‑ocular skin.
• Dry eye sensation.

Serious or Rare Side Effects

• Severe allergic reaction (e.g., angio‑edema, anaphylaxis).
• Sudden loss of vision or acute ocular pain.
• Systemic bradycardia or hypotension.
• Respiratory distress in patients with asthma or COPD.
• Persistent corneal edema.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis.

• Before using Latanoprost/Timolol, consider the following safety measures.
• Assess respiratory status: avoid in patients with uncontrolled asthma or severe COPD.
• Cardiovascular evaluation: contraindicated in bradycardia, heart block, or decompensated heart failure.
• Pregnancy and lactation: use only if the potential benefit justifies the potential risk.
• Monitor intra‑ocular pressure: regular eye‑pressure checks are required to assess efficacy.
• Avoid concurrent beta‑blocker eye drops: may increase systemic absorption.
• Store at room temperature: keep the bottle in the original packaging, protect from light and moisture.

Latanoprost/Timolol may interact with other medicines; monitor patients accordingly.

Major Interactions (Avoid)

• Asthma or severe COPD medications: additive bronchoconstriction risk.
• Systemic beta‑blockers: may cause excessive bradycardia or hypotension.
• Calcium channel blockers: can enhance timolol‑induced cardiac effects.

Moderate Interactions (Monitor Closely)

• Other intra‑ocular pressure‑lowering agents (e.g., carbonic anhydrase inhibitors): may increase ocular hypotension.
• Anticholinergic eye drops: could affect pupil size and comfort.
• Non‑steroidal anti‑inflammatory drugs (topical): may alter prostaglandin metabolism.
