Frequently Asked Questions

What is betaxolol (Betoptic, Kerlone, Optipres) and what is it used for?

Short Answer

Betaxolol is an eye drop for treating some types of glaucoma and ocular hypertension.

Long Answer

Betaxolol (be TAKS oh lol) Hydrochloride is a beta blocker sold as Betoptic, Kerlone, Lokren, and Optipres as an eye solution for treating chronic open-angle glaucoma and ocular hypertension.

It is also available as oral tablets (sometimes with diuretic therapy) for the management of other types of hypertension. These types of beta-blockers are used to affect the heart and circulation.

As with other medications that are applied directly to the eye, it may be absorbed into the bloodstream. Please consult your health professional before taking this or any other medication to ensure you know all the facts about potential side effects.

Additional Information

Wikipedia: Betaxolol
Betaxolol (trade names Betoptic, Betoptic S, Lokren, Kerlone) is a selective beta1 receptor blocker used in the treatment of hypertension and glaucoma. Being selective for beta1 receptors, it typically has fewer systemic side effects than non-selective beta-blockers, for example, not causing bronchospasm (mediated by beta2 receptors) as timolol may. Betaxolol also shows greater affininty for beta1 receptors than metoprolol. In addition to its effect on the heart, betaxolol reduces the pressure within the eye (intraocular pressure). This effect is thought to be caused by reducing the production of the liquid (which is called the aqueous humor) within the eye. The precise mechanism of this effect is not known. The reduction in intraocular pressure reduces the risk of damage to the optic nerve and loss of vision in patients with elevated intraocular pressure due to glaucoma. Betaxolol was approved by the U.S. Food and Drug Administration (FDA) for ocular use as a 0.5% solution (Betoptic) in 1985 and as a 0.25% solution (Betoptic S) in 1989.
MedicineNet.com: Betaxolol ophthalmic solution
Betaxolol is used for the treatment of glaucoma. Note that the type of glaucoma for which Betoptic S or Betoptic usually is prescribed is the chronic open-angle type of glaucoma. (Oral betaxolol tablets are used for treating high blood pressure and angina, but this dosage form is not discussed here.)
MedlinePlus Drug Information: Betaxolol Ophthalmic
Betaxolol comes as eyedrops. Betaxolol usually is used twice a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use betaxolol exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor. If you are using the suspension form of betaxolol eyedrops (Betoptic S), shake the bottle well before each dose. It is not necessary to shake betaxolol eyedrop solution. Betaxolol controls glaucoma but does not cure it. Continue to use betaxolol even if you feel well. Do not stop using betaxolol without talking to your doctor.
RxList.com: Kerlone
The initial dose of Kerlone in hypertension is ordinarily 10 mg once daily either alone or added to diuretic therapy. The full antihypertensive effect is usually seen within 7 to 14 days. If the desired response is not achieved the dose can be doubled after 7 to 14 days. Increasing the dose beyond 20 mg has not been shown to produce a statistically significant additional antihypertensive effect; but the 40-mg dose has been studied and is well tolerated. An increased effect (reduction) on heart rate should be anticipated with increasing dosage. If monotherapy with Kerlone does not produce the desired response, the addition of a diuretic agent or other antihypertensive should be considered.
