Latanoprost/Timolol Zentiva (Timolol Maleate, Latanoprost)

• Latanoprost/Timolol Zentiva is used in the management of ocular conditions that require reduction of intra‑ocular pressure.
• Open‑angle glaucoma: reduces intra‑ocular pressure to prevent optic nerve damage.
• Ocular hypertension: lowers eye pressure to reduce risk of progression to glaucoma.
• Secondary glaucoma: helps control pressure when monotherapy is insufficient.

• The latanoprost component is a prostaglandin F2α analogue that increases uveoscleral outflow of aqueous humor, while timolol maleate is a non‑selective β‑adrenergic antagonist that decreases aqueous humor production by blocking β‑receptors in the ciliary body. The combined actions enhance aqueous outflow and reduce formation, resulting in a net decrease of intra‑ocular pressure. By targeting both production and drainage pathways, the formulation provides more consistent pressure control than either agent alone.

Latanoprost/Timolol Zentiva may cause ocular and systemic adverse reactions.

Common Side Effects

• Eye irritation or burning sensation.
• Blurred vision.
• Redness of the eye (hyperemia).
• Itching or mild allergic reaction on the eyelid.
• Dry eye sensation.
• Foreign body feeling.

Serious or Rare Side Effects

• Severe allergic reaction with swelling of the eyelid or face.
• Sudden loss of vision.
• Marked decrease in heart rate or low blood pressure.
• Exacerbation of asthma or bronchospasm.
• Persistent eye pain unresponsive to treatment.

• Before using Latanoprost/Timolol Zentiva, consider the following precautions.
• Pregnancy: consult a healthcare professional as safety has not been established.
• Breastfeeding: use with caution; potential exposure to the infant is unknown.
• Cardiovascular disease: monitor heart rate and blood pressure due to beta‑blocker effects.
• Respiratory disorders: avoid in patients with asthma or severe COPD because of possible bronchospasm.
• Drug interactions: review concomitant medications for potential additive beta‑blockade or prostaglandin effects.
• Store at room temperature: keep below 25 °C in the original container, protected from light and moisture.

Latanoprost/Timolol Zentiva can interact with other medicines; notable interactions include.

Major Interactions (Avoid)

• Systemic non‑selective beta‑blockers: may cause excessive bradycardia or hypotension.
• Inhaled sympathomimetics (e.g., epinephrine): may reduce ocular efficacy.
• Other prostaglandin analog eye drops: risk of additive ocular side effects.
• Calcium channel blockers: may enhance intra‑ocular pressure‑lowering effect leading to over‑reduction.
• Monoamine oxidase inhibitors: may increase risk of bronchospasm.

Moderate Interactions (Monitor Closely)

• Topical corticosteroids: may diminish pressure‑lowering response.
• Anticholinergic eye drops: may affect pupil size and drug absorption.
• Systemic antihypertensives: monitor for additive blood pressure lowering.
• NSAID eye preparations: watch for increased ocular irritation.
• Diuretics: observe for electrolyte disturbances in susceptible patients.
