Description

Opsonin pharma has launched the preservative-free sterile eye drops preparation with OSD (Ophthalmic squeeze dispenser) for the first time in Bangladesh.

This eye drops is comprised of two components: Brimonidine Tartrate & Timolol Maleate. Brimonidine Tartrate is a selective alpha-2 adrenergic receptor agonist having a dual mechanism of action. It decreases aqueous humor production and increases nonpressure dependent uveoscleral outflow. Timolol Maleate is a β-adrenergic receptor antagonist that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. It lowers IOP by reducing aqueous humor production. Therefore the combination of both drugs gives a rapid onset of action, with peak ocular hypotensive effect seen within two hours of administration.

Instill 1 drop in the affected eye(s) twice daily.

Specific drug interaction studies have not been conducted.

Contraindicated in patients with hypersensitivity to any component of this product. Also contraindicated in bronchial asthma, severe chronic obstructive pulmonary disease, sinus bradycardia, second or third-degree atrioventricular block, overt cardiac failure and cardiogenic shock.

The most common side effects are allergic conjunctivitis, conjunctival folliculosis, conjunctival hyperaemia, eye pruritus and ocular burning or stinging.

There are no adequate and well-controlled studies in pregnant women. Combipres should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Timolol has been detected in human milk but it is not known whether Brimonidine Tartrate is excreted in human milk. A decision should be made whether to discontinue nursing or to discontinue taking into account the importance of the drug to the mother.

Like other topically applied ophthalmic agents, it may be absorbed systemically. Due to the presence of Timolol, the same types of cardiovascular and pulmonary adverse reactions as seen with systemic beta-blockers may occur. Cautions should be exercised in treating patients with severe or unstable and uncontrolled cardiovascular or pulmonary diseases.

Use in children: Safety and effectiveness in children below the age of 2 years have not been established. Use in elderly patients: No overall differences in safety or effectiveness have been observed between elderly and other adult patients.
