Betagan (Levobunolol Hydrochloride Eye Drops) Dropshipper
Betagan eye drops contain the active ingredient levobunolol hydrochloride, which is a type of medicine called a beta-blocker. (NB. Levobunolol eye drops are also available without a brand name, ie as the generic medicine.) Levobunolol is used to reduce the pressure inside the eyeball. It works by blocking beta-receptors in the eye. The pressure within the eyeball is naturally maintained by a continuous flow of liquid called aqueous humour through the eyeball. Aqueous humour is produced by a part of the eye called the ciliary body, and it drains out of the eyeball through channels called the trabecular meshwork. If the outflow of aqueous humour is blocked, the aqueous humour builds up inside the eye, increasing the pressure within the eyeball. This pressure needs to be reduced, as otherwise it can damage the optic nerve and impair vision. Levobunolol blocks beta-receptors that are found on the ciliary body. This action reduces the amount of aqueous humour that is secreted into the eyeball by the ciliary body. Levobunolol also blocks beta-receptors found on the blood vessels that supply the ciliary body. This causes these blood vessels to constrict, which reduces the amount of watery fluid that filters out of the blood vessels to form aqueous humour. The overall effect of levobunolol is to reduce the inflow of aqueous humour into the eyeball, which decreases the pressure within the eye. It is used to treat conditions where there is raised pressure in the eye, such as glaucoma.
