The renal clearances and plasma protein binding of three drugs in a 70 kg adult are as follows: Drug Renal Clearance (ml/min) % bound to plasma proteins 50 Theophylline Phenytoin Cefonicid 10 0.15 90 20 98 If GFR is 120 ml/min and urine flow is 1.5 ml/min, what is the likely involvement of filtration, secretion and reabsorption in the renal excretion of each of these drugs?
