I got this question in class test.

I want to ask this question from Pharmacokinetic in chapter Pharmacokinetic Drug Interactions & Basic Considerations of Drug Biotechnology

Answer 1

The correct choice is (c) 96.25 ml/min

The best explanation: For females of age above 20 years the equation for creatinine clearance is (140-age)*W/85*Scr where, Clcr is creatinine clearance in ml/min, Scr is serum creatinine in mg%, H is height in cms, W is weight in kg, age is in years.
