The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.

DOSAGE MUST BE INDIVIDUALIZED (SEE INDICATIONS). CORZIDE MAY BE ADMINISTERED WITHOUT REGARD TO MEALS.

Bendroflumethiazide is usually given at a dose of 5 mg daily. The usual initial dose of nadolol is 40 mg once daily whether used alone or in combination with a diuretic. Bendroflumethiazide in CORZIDE is 30 percent more bioavailable than that of 5 mg Naturetin tablets. Conversion from 5 mg NATURETIN to CORZIDE represents a 30 percent increase in dose of bendroflumethiazide.

The initial dose of CORZIDE (Nadolol and Bendroflumethiazide Tablets) may therefore be the 40 mg/5 mg tablet once daily. When the antihypertensive response is not satisfactory, the dose may be increased by administering the 80 mg/5 mg tablet once daily.

When necessary, another antihypertensive agent may be added gradually beginning with 50 percent of the usual recommended starting dose to avoid an excessive fall in blood pressure.

Dosage Adjustment in Renal Failure—Absorbed nadolol is excreted principally by the kidneys and, although nonrenal elimination does occur, dosage adjustments are necessary in patients with renal impairment. The following dose intervals are recommended:

Creatinine Clearance

>50 24
31–50 24–36
10–30 24–48
