Abstract:
Felodipine (0.075 mg/kg p.o.), a calcium antagonist, was given to 9 male volunteers, with and without indomethacin pretreatment. Diuresis and natriuresis occurred after felodipine without significant change in effective renal plasma flow or glomerular filtration rate. There was no significant change in urinary 6 keto PGF 1 alpha or urinary kallikrein excretion and indomethacin did not inhibit the natriuretic or diuretic response to felodipine. The felodipine induced diuresis and natriuresis appears most likely to be mediated by an action of the drug on renal tubules.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
