If the intraocular pressure exceeds the normal limit, the patient may have glaucoma; however, this may not be true all the time. Metoprolol (Lopressor, Toprol XL) is a beta-adrenergic blocking agent drug, which blocks the action of the sympathetic nervous system (a portion of the involuntary nervous system).
