Answer»

The correct choice is (a) True

The explanation: PENICILLIN has a short plasma half-life. Though it can rigidly bind to the plasma still it has short ELIMINATION half live. This is because equilibration occurs between the free and the bound PROTEIN and the free drug is equally rapidly excreted by active secretion in renal TUBULES.
