The clinical relevance of ISA in <strong>glaucoma</strong> therapy has not yet been proven. Action Decreases intraocular pressure by reduction of the aqueous humor production. Peak effect in 2 hrs. Dosage <strong>and</strong> administration Starting dose is one drop of lowest concentration of solution in the affected eye once or twice a day. If the clinical response is not adequate, the dosage may be increased to one drop of a higher concentration. Nyogel, Timolol in gelrite (Timoptic-XE, Timacar Depot, Timoptol XE, <strong>and</strong> Timosan Depot) is given once daily. No dose response curves <strong>for</strong> the different beta-blocker treatments have been established. The lowest concentration that would give the expected clinical effect should be used to avoid side defects. Dosing more than twice daily will not give any further pressure lowering effect. Minimal extra effect with dipivefrine. No extra effect with adrenaline (epinephrine). Additive effect with most other IOP-lowering agents. Preservativa-free preparations are available <strong>and</strong> may be considered Indications Elevation of intraocular pressure in patients where the IOP can be deleterious <strong>for</strong> the preservation of visual function. Beta-1 selective adrenergic antagonist despite lowering IOP less than non selective, protect visual field as well as non selective ones. Major Contraindications Non-selective: Asthma, history of obstructive pulmonary disease, sinus bradycardia (< 60 beats/min), heart block, or cardiac failure Beta-1 selective:Relative contraindication in asthma, history of obstructive pulmonary disease, sinus bradycardia (< 60 beats/min), heart block, or cardiac failure Major side effects Non-selective: Systemic: Bradycardia, arrhythmia, heart failure, syncope, bronchospasm, <strong>and</strong> airways obstruction. Distal edema, hypotension. Depression. Hypoglycemia may be masked in insulin dependent diabetes mellitus. Betablocking agents have been associated with nocturnal hypotension, which may be a risk factor in progression of <strong>glaucoma</strong>tous optic nerve damage 52 . Ocular (uncommon): Epithelial keratopathy, slight reduction in corneal sensitivity. Beta-1 selective: Better tolerated in most patients sensitive to non-selective agents. Ch. 3 - 12 EGS
Pregnancy <strong>and</strong> nursing mothers Only to be used if the potential benefit justifies the potential risk to the fetus or the infant. Drug interactions Oral or intravenous calcium antagonists: caution should be used in the co-administration of beta-adrenergic blocking agents <strong>and</strong> oral or intravenous calcium antagonists, because of possible atrioventricular conduction disturbances, left ventricular failure, <strong>and</strong> hypotension. Digitalis <strong>and</strong> calcium antagonists: the concomitant use of beta-adrenergic blocking agents with digitalis may have additive effects in prolonging conduction time. Catecholamine-depleting drugs: possible additive effects <strong>and</strong> the production of hypotension <strong>and</strong>/or marked bradycardia. Wash-out The time needed <strong>for</strong> beta blockers to completely lose their activity is 2-5 weeks. Ch. 3 - 13 EGS
