Description
Glaucoma Treatment
Combigan (Brimonidine/Timolol)
Combigan is a combination of 2 drugs used to treat high-pressure symptoms of the eye, namely glaucoma (open-angle type) and some other eye diseases like ocular hypertension. Lowering the pressure in the eye helps prevent blindness in these conditions. Combigan eye drops are used when single-ingredient drugs are unable to treat glaucoma.
The 2 drugs in Cambigan are brimonidine and timolol. Brimonidine is an alpha agonist. It acts by decreasing the amount of fluid formed in the eye along with improving the fluid drainage from within the eye. Timolol belongs to the group of beta blockers. It decreases the amount of fluid formed within the eye. The effect of both drugs results in lowering the intra ocular pressure and giving relief to the patient.
Combigan eye drops are not recommended for children under 2 years of age due to increased risk of side effects.
You can buy Combigan eye drops for glaucoma treatment from Canada Pharmacy and have it delivered to you.
