Renal Dose Adjustments

Since Optilax is partially metabolized in the liver and excreted mainly by the kidneys, dosage reductions may be necessary when hepatic and/or renal insufficiency is present. Although the pharmacokinetics of Optilax are not greatly altered by renal impairment, marked hypotensive responses have been seen in patients with marked renal impairment undergoing dialysis after 20 mg doses. Dosing in such patients should therefore be especially cautious.

Liver Dose Adjustments

Since Optilax is partially metabolized in the liver and excreted mainly by the kidneys, dosage reductions may be necessary when hepatic and/or renal insufficiency is present.

Dose Adjustments

The dose may be titrated as needed every 7 days.

For migraine prophylaxis, a 20 mg daily dose may be administered as a single dose. Total daily dosage may be increased to a maximum of 30 mg, given in divided doses, or decreased to 10 mg once a day, depending on clinical response and tolerability. If a satisfactory response is not obtained after 6-8 weeks use of the maximum daily dosage, therapy with Optilax should be discontinued.

Precautions

Gradual discontinuation of therapy is recommended to prevent rebound hypertension and/or angina pectoris.

Safety and effectiveness have not been established in pediatric patients (less than 18 years of age).

Dialysis

Optilax is not significantly dialyzed. Limited data from 2 patients undergoing hemodialysis using a Travenol UF II standard coil dialyzer reveal no significant difference between the arterial and venous plasma concentrations during dialysis. Since Optilax is not significantly removed by hemodialysis, supplemental dosing after dialysis is not necessary. Be cognizant of the increased risk of hypotension if Optilax is administered immediately after dialysis sessions. Ideally, Optilax should be administered at some time after dialysis when the patient is hemodynamically stable.

Other Comments

The maximum recommended daily dose is 60 mg in 2 divided doses.

Compared with Caucasian patients, Black patients have a reduced blood pressure response to monotherapy with beta blockers; however, the reduced response is largely eliminated if combination therapy that includes an adequate dose of a diuretic is instituted.

Beta-adrenergic blocking agents: Patients who are receiving a beta-adrenergic blocking agent orally and Phoxal-Optilax GFS should be observed for potential additive effects of beta-blockade, both systemic and on intraocular pressure. Patients should not usually receive two topical ophthalmic beta-adrenergic blocking agents concurrently.

Calcium antagonists: Caution should be used in the co-administration of beta-adrenergic blocking agents, such as Phoxal-Optilax GFS, and oral or intravenous calcium antagonists because of possible atrioventricular conduction disturbances, left ventricular failure, or hypotension. In patients with impaired cardiac function, co-administration should be avoided.
