Uses of Brimonidine: It is a drug used to treat open-angle glaucoma or ocular hypertension. And as a treatment for glaucoma, it is usually given in eyedrop form. It is also an alpha 2 agonists, and inhibits the activity of adenylate cyclase. This reduces cAMP and hence aqueous humour production by the ciliary body.
You should be cautious while dealing with this chemical. It irritates eyes, respiratory system and skin, and it is also toxic if swallowed. Therefore, you had better take the following instructions: Wear suitable protective clothing, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).
