Action/Kinetics: Exerts both beta-1- and beta-2-adrenergic blocking activity. Has minimal sympathomimetic effects, direct myocardial depressant effects, or local anesthetic action. Does not cause pupillary constriction or night blindness. The mechanism of the protective effect in MI is not known. Peak plasma levels: 1-2 hr. t 1/2: 4 hr. Metabolized in the liver. Metabolites and unchanged drug excreted through the kidney. Also reduces both elevated and normal IOP, whether or not glaucoma is present; thought to act by reducing aqueous humor formation and/or by slightly increasing outflow of aqueous humor. Does not affect pupil size or visual acuity. For use in eye: Onset: 30 min. Maximum effect: 1-2 hr. Duration: 24 hr.

Uses: Tablets: Hypertension (alone or in combination with other antihypertensives such as thiazide diuretics). Within 1-4 weeks of MI to reduce risk of reinfarction. Prophylaxis of migraine. Investigational: Ventricular arrhythmias and tachycardias, essential tremors.

Contraindications: Hypersensitivity to drug. Bronchial asthma or bronchospasm including severe COPD.

Special Concerns: Use ophthalmic preparation with caution in clients for whom systemic beta-adrenergic blocking agents are contraindicated. Safe use in children not established.

Side Effects: Systemic following use of tablets: See Beta-Adrenergic Blocking Agents.
Following use of ophthalmic product: Few. Occasionally, ocular irritation, local hypersensitivity reactions, slight decrease in resting HR.

Laboratory Test Alterations: BUN, serum potassium, and uric acid. H&H.

Drug Interactions: When used ophthalmically, possible potentiation with systemically administered beta-adrenergic blocking agents.

I think it's sad that my country alolws pharmaceutical companies to advertise the way they do. The goal should be to get people with the right medication regardless who produces it. Mental illness diagnostics is all about what the patient tells the doctor since technology hasn't given us definite physical tests yet. If the patient goes in thinking they have the symptoms they saw in an ad and need the meds for it, the doctor will likely end up prescribing it or something similar. Some doctors let themselves be influenced by the drug companies as well. I've sometimes left their office with a handful of samples feeling like a guinea pig. This is new and sounds good. Try this! America would be a lot healthier if it wasn't all about the money.
