What start does Child-Pugh B use?
A starting dose of 5 mg is recommended. The maximum dose must not exceed 10 mg.
That 10 mg ceiling is not the usual adult 20 mg ceiling. Do not climb past it because a review praised 20.
Dialysis is a separate off
Do not use vardenafil in patients on renal dialysis. It has not been evaluated there.
CLcr 30-80 mL/min needs no adjustment. CLcr under 30 showed AUC 20-30% higher in volunteers, still not the dialysis off. Keep those rows apart.
Child-Pugh A numbers
Mild impairment raised Cmax 22% and AUC 17% after 10 mg. No dosage adjustment is necessary.
Mild is not moderate. Do not borrow the B ceiling for an A chart unless the clinician has another reason.
How much did 10 mg rise in moderate impairment?
In volunteers with Child-Pugh B, Cmax after 10 mg was 130% higher and AUC was 160% higher than in healthy controls.
Those percents are why the start drops and the ceiling stops at 10 mg. This room will not add a second PK cascade.
Alpha-blocker 5 mg is not liver math
A 5 mg vardenafil start next to a stable alpha-blocker is blood-pressure math. It is not Child-Pugh B.
That pair lives on the alpha-blocker scan. Age 65's 5 mg lives on the age scan.
Is Child-Pugh C allowed?
No. Do not use vardenafil hydrochloride in severe hepatic impairment. The drug was not evaluated in that group.
A forum average of 10 mg does not rewrite that off. The prescriber who owns the liver chart has to see the row.
