Basic Drug Info
Drug Name:Metipranolol
Manufacturer:Falcon Pharmaceuticals, Ltd.
Other Info:

In patients with angle-closure glaucoma, the immediate treatment objective is to re-open the angle by constriction of the pupil with a miotic agent.

Metipranolol ophthalmic solution has little or no effect on the pupil, therefore, when it is used to reduce intraocular pressure in angle-closure glaucoma, it should be used only with concomitant administration of a miotic agent.



Clinical Trials:


Indications and Usage
Metipranolol ophthalmic solution is indicated in the treatment of elevated intraocular pressure in patients with ocular hypertension or open angle glaucoma.
Intraocular pressure disorder --

Ocular Hypertension -- A condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.

Open Angle Glaucoma -- Glaucoma in which the angle of the anterior chamber is open and the trabecular meshwork does not encroach on the base of the iris.

Contraindications
Hypersensitivity to any component of this product.Metipranolol ophthalmic solution is contraindicated in patients with bronchial asthma or a history of bronchial asthma, or severe chronic obstructive pulmonary disease; symptomatic sinus bradycardia; greater than a first degree atrioventricular block; cardiogenic shock; or overt cardiac failure.
Hypersensitivity -- Altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen.

Asthma -- A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).

Sinus bradycardia -- A heart rate of less than 60 beats per minute, with its origin in the sinus node. (NCI)

First degree atrioventricular block -- A delay in the time required for the conduction of an electrical impulse through the atrioventricular (AV) node beyond 0.2 seconds; prolongation of the PR interval beyond 200 milliseconds.

Cardiogenic shock -- Shock resulting from diminution of cardiac output in heart disease.

Heart failure -- inability of the heart to pump blood at an adequate rate to fill tissue metabolic requirements or the ability to do so only at an elevated filling pressure.

Warnings

As with other topically applied ophthalmic drugs, this drug may be absorbed systemically.

Thus, the same adverse reactions found with systemic administration of beta-adrenergic blocking agents may occur with topical administration.

For example, severe respiratory reactions and cardiac reactions, including death due to bronchospasm in patients with asthma, and rarely, death in association with cardiac failure, have been reported following topical application of beta-adrenergic blocking agents (see CONTRAINDICATIONS).Since metipranolol ophthalmic solution had a minor effect on heart rate and blood pressure in clinical studies, caution should be observed in treating patients with a history of cardiac failure.

Treatment with metipranolol ophthalmic solution should be discontinued at the first evidence of cardiac failure.Metipranolol ophthalmic solution, or other beta-blockers, should not, in general, be administered to patients with chronic obstructive pulmonary disease (e.g., chronic bronchitis, emphysema) of mild or moderate severity (see CONTRAINDICATIONS).

However, if the drug is necessary in such patients, then it should be administered with caution since it may block bronchodilation produced by endogenous and exogenous catecholamine stimulation of beta2 receptors.
