What is Alphagan?

A medicine from the sympathomimetic group applied topically to the eye (into the conjunctival sac) to reduce intraocular pressure.

What does Alphagan contain and how does it work?

The active substance is brimonidine, a drug from the sympathomimetic group. Sympathomimetics work by stimulating a specific type of receptors, the so-called adrenergic receptors on the surface of target cells. These are receptors stimulated in physiological conditions by adrenaline or noradrenaline released after the activation of the sympathetic nervous system. Brimonidine is selective for alpha-2 adrenergic receptors, which means that it does not affect alpha-1 receptors at the doses used. Thanks to the selective action, it does not dilate the pupil. It lowers intraocular pressure both by reducing the production of aqueous humor and by increasing its outflow. In the form of eye drops, brimonidine is applied to the conjunctival sac. It exerts a local action, is also absorbed into the systemic circulation and may cause systemic side effects. It affects the functioning of the cardiovascular and respiratory systems to a minimum.
The preparation is characterized by a rapid onset of action. The maximum effect occurs after 2 hours after topical application to the eye. The drug is mainly excreted through the kidneys. Brimonidine is used as monotherapy or in combination with beta-blockers or prostaglandin analogs.

The preparation is indicated to lower the increased intraocular pressure in patients with open-angle glaucoma or ocular hypertension.
The preparation can be used:
· As monotherapy in patients in whom the use of topical beta-blockers (another name is beta-blockers) is contraindicated
· As adjunctive therapy in combination with other drugs that lower the intraocular pressure, when lowering the pressure with just one drug is insufficient.
