Indications
Betaxolol Hydrochloride ophthalmic solution lowers intraocular pressure, and it has been shown to work. Doctors prescribe it for ocular hypertension and for chronic open-angle glaucoma. You can use Betaxolol Hydrochloride on its own, or together with other medicine that lowers intraocular pressure.
⚠️ Always consult a registered physician before taking any medicine.
Pharmacology
Betaxolol is a selective beta-1-adrenergic receptor blocking agent. It has no significant membrane stabilizing (local anesthetic) activity and no intrinsic sympathomimetic action. When it is instilled into the eye, Betaxolol lowers raised intraocular pressure and also normal intraocular pressure, whether or not the person has glaucoma. A sustained rise in intraocular pressure and poor ocular perfusion lead to optic nerve head damage and visual field loss.
The pressure-lowering effect of Betaxolol appears to come from a reduction in aqueous production, as shown by tonography and aqueous flurophotometry. Unlike miotics, Betaxolol ophthalmic solution does not cause miosis or accommodative spasm, which are frequently seen with those medicines.
The effect can generally be noticed within 30 minutes of topical use, and the maximal effect can usually be detected two hours after administration. A single dose reduces intraocular pressure (IOP) for 12 hours, and with twice daily use the IOP stays below 22 mm Hg in most patients.
Pregnancy & Breastfeeding
No adequate and well controlled studies have been done in pregnant women. Betaxolol ophthalmic solution should be used during pregnancy only if the possible benefit justifies the possible risk.
It is not known whether betaxolol passes into human milk. The risk of hypoglycemia and bradycardia in a nursing infant has not been evaluated. Breastfeeding is not recommended during treatment.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
