Patient w/ 1st degree heart block, severe peripheral circulatory disorders (e.g. severe forms of Raynaud's disease/syndrome), mild/moderate COPD, corneal disease, labile diabetes or those who are subject to spontaneous hypoglycaemia. Aphakic patients, pseudoaphakic patients w/ torn posterior lens capsule or anterior chamber lenses or to those at risk for cystoid macular oedema. Lactation.
Open-angle glaucoma,Ocular hypertension
Reactive airway disease including existing or history of bronchial asthma; severe COPD; sinus bradycardia, sick sinus syndrome including sino-atrial block, 2nd- or 3rd-degree AV block (not controlled by pacemaker); overt cardiac failure, cardiogenic shock; severe allergic rhinitis, corneal dystrophies.

Exact mechanism of ocular hypotensive effect is unclear, but it is thought to be related to reduction of aqueous humour formation. beta-blockade also causes lowering of BP. Travoprost, a prodrug and synthetic analogue of dinoprost (prostaglandin F2alpha), reduces intraocular pressure by increasing uveoscleral outflow of aqueous humour.
Potential additive effect w/ oral Ca channel blockers, ?-adrenergic blockers, antiarrhythmics, digitalis glycosides, parasympathomimetics, guanethidine. May potentiate hypertensive reaction to sudden withdrawal of clonidine. May potentiate systemic ?-blockade w/ CYP2D6 inhibitors (e.g. quinidine, paroxetine). Risk of mydriasis w/ epinephrine. May increase the hypoglycaemic effect of antidiabetic agents.
