This means that, with a consultation, Combigan can be delivered right to your doorstep.

This convenience is particularly appealing for those managing chronic conditions requiring regular medication such as eye drops. Moreover, prices at online pharmacies sometimes come in lower than physical chains, adding another layer of benefits when opting for online purchases.

Mechanism & Pharmacology

Simplified explanation

Combigan eye drops consist of two active ingredients: brimonidine and timolol. Brimonidine reduces the production of fluid in the eye and increases the amount of fluid that drains out, effectively lowering intraocular pressure. Timolol also works by reducing the production of fluid in the eye.

This combination works well in treating elevated eye pressure associated with conditions like glaucoma. For users, the essence of how Combigan operates hinges on its dual action—working on both fluid production and drainage improves overall eye health.

Clinical terms

Understanding the pharmacological aspects of Combigan requires knowledge of a few key clinical terminologies:

• Alpha-agonist: A type of medication that activates alpha receptors, leading to a decrease in aqueous humour production.
• Beta-blocker: Reduces the heart rate and decreases intraocular pressure by blocking the effects of adrenaline.
• Aqueous humour: The clear fluid in the front part of the eye essential for maintaining intraocular pressure.

These terms help explain how Combigan manages elevated eye pressure, vital in combating conditions like glaucoma and preventing sight loss.

Indications & Off-Label Uses

Approved indications by TGA

The Therapeutic Goods Administration (TGA) approves Combigan eye drops explicitly for managing elevated intraocular pressure in individuals diagnosed with open-angle glaucoma or ocular hypertension. This authorised use showcases the medication's efficacy and safety when prescribed appropriately to Australian patients.

Off-label uses in Australian clinical practice

While primarily prescribed for glaucoma and ocular hypertension, some practitioners may choose to use Combigan off-label for patients who exhibit higher intraocular pressure unresponsive to first-line treatments. Cases with unique complications or specific patient needs can lead to this decision, ensuring comprehensive eye health management.

Key Clinical Findings

Recent studies conducted from 2022 to 2025, both nationally and internationally, have underscored Combigan's effectiveness in the management of eye pressure. One major Australian study highlighted a significant reduction in intraocular pressure levels, often more pronounced than with monotherapy treatments.

Internationally, findings suggest that Combigan is particularly beneficial for patients with coexisting conditions such as diabetes, where ocular hypertension risk increases. The dual-action mechanism is particularly effective, making it a leading choice among ophthalmologists.
