Monoprost Duo (Latanoprost, Timolol)

Latanoprost/Timolol, the active ingredient in Monoprost Duo, is a prostaglandin analog / beta‑blocker presented as eye drops for ocular use. It lowers intra‑ocular pressure by increasing aqueous outflow and reducing aqueous production, thereby managing open‑angle glaucoma and ocular hypertension in adult patients.

GNH India supplies Monoprost Duo as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide, providing reliable access to regulated ophthalmic medicines. The product complies with EU pharmacopeial standards and is distributed under strict quality‑assurance protocols.

Indications & Clinical Uses

  • Monoprost Duo, a combination prostaglandin analog and beta‑blocker, is used to manage conditions that involve elevated intra‑ocular pressure.
  • Open‑angle glaucoma: reduces intra‑ocular pressure to slow disease progression.
  • Ocular hypertension: lowers pressure to prevent conversion to glaucoma.
  • Post‑surgical ocular pressure spikes: helps control pressure after ocular surgery.

How It Works

  • Latanoprost acts as an FP‑receptor agonist, enhancing uveoscleral outflow of aqueous humor, while timolol non‑selectively blocks β‑adrenergic receptors in the ciliary body, decreasing aqueous humor production. The combined actions result in a net reduction of intra‑ocular pressure.

Side Effects

Monoprost Duo may cause a range of ocular and systemic reactions.

Common Side Effects

  • Eye irritation or burning sensation.
  • Blurred vision shortly after instillation.
  • Conjunctival hyperemia (eye redness).
  • Increased eyelash length or pigmentation changes.

Serious or Rare Side Effects

  • Severe allergic reaction with swelling of the eyelids.
  • Persistent ocular pain or inflammation.
  • Sudden loss of vision.
  • Systemic bradycardia or hypotension.
  • Exacerbation of asthma or COPD symptoms.

Precautions & Warnings

  • Before prescribing Monoprost Duo, clinicians should consider several safety aspects.
  • Assess baseline intra‑ocular pressure and visual field status.
  • Monitor for beta‑blocker contraindications such as asthma, COPD, or bradycardia.
  • Avoid use in patients with known hypersensitivity to any component.
  • Exercise caution in pregnancy or breastfeeding; risk data are limited.
  • Do not combine with other prostaglandin analog eye drops.
  • Store at room temperature: keep bottle tightly closed, protect from light and moisture.

Avoid Interactions

Monoprost Duo can interact with other medications affecting ocular pressure or systemic beta‑adrenergic activity.

Major Interactions (Avoid)

  • Systemic non‑selective beta‑blockers (e.g., propranolol) – additive bradycardia.
  • Sympathomimetic ophthalmic agents (e.g., phenylephrine) – reduced IOP‑lowering effect.
  • Concurrent prostaglandin analog eye drops – risk of excessive ocular effects.

Moderate Interactions (Monitor Closely)

  • Carbonic anhydrase inhibitor eye drops (e.g., dorzolamide) – additive IOP reduction.
  • Systemic antihypertensive drugs – monitor blood pressure.
  • Anticholinergic ophthalmic preparations – may affect ocular surface tolerance.

Frequently Asked Questions

Monoprost Duo is a prescription ophthalmic solution that combines latanoprost and timolol to lower intra‑ocular pressure. It is indicated for the treatment of open‑angle glaucoma and ocular hypertension, helping to prevent optic nerve damage and preserve visual function in adult patients.

Latanoprost, a prostaglandin analog, increases uveoscleral outflow of aqueous humor, while timolol, a non‑selective beta‑blocker, reduces aqueous humor production by blocking β‑adrenergic receptors in the ciliary body. The dual mechanism results in a net decrease in intra‑ocular pressure.

The dosing regimen for Monoprost Duo is determined by the prescribing ophthalmologist based on the individual patient's condition, response, and tolerance. Typically, one drop is instilled in the affected eye(s) once daily, but the exact schedule should follow the prescriber’s instructions.

Safety data for Monoprost Duo in pregnancy and lactation are limited. It should only be used if the potential benefit justifies any potential risk to the fetus or infant, and the decision should be made by the treating physician in consultation with the patient.

To order Monoprost Duo, submit an enquiry on the product page at gnhindia.com specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams worldwide, and will request trade or institutional credentials before providing pricing, availability, shipping details and any necessary import documentation.

Monoprost Duo combines two mechanisms—enhanced outflow and reduced production—offering greater IOP reduction than single‑agent prostaglandin analogs or beta‑blockers alone. Compared with other combination drops, it provides a convenient once‑daily regimen, but choice of therapy should be individualized based on efficacy, tolerability and patient comorbidities.

Monoprost Duo should be stored at room temperature, below 25 °C, in the original container. Keep the bottle tightly closed, protect it from light and moisture, and discard any solution that appears discolored or contains particles.

The product is administered as an ocular drop. The patient should wash hands, tilt the head back, pull down the lower eyelid to create a small pocket, and place one drop into the conjunctival sac of each prescribed eye. Avoid touching the tip of the bottle to the eye or any surface.

Serious risks include severe allergic reactions, persistent ocular pain or inflammation, sudden loss of vision, systemic bradycardia, and exacerbation of asthma or chronic obstructive pulmonary disease. Patients should seek immediate medical attention if they experience any of these symptoms.

Monoprost Duo is contraindicated in patients with known hypersensitivity to latanoprost, timolol or any excipients, and in those with active ocular infections or inflammation. It should also be avoided in individuals with severe asthma, COPD, bradycardia, or uncontrolled heart failure unless specifically advised by a physician.
