<prompt> Which statement about first order kinetics is TRUE?Constant amount of drug is eliminatedRate of elimination remains constantRate of elimination is directly propoional to drug concentrationFree drug concentration increases after successive doses  <response>: In first orderexponential kinetics: Rate of elimination is propoional to the plasma drug concentration Clearence and tl2 remains constant Constant fraction of the drug is eliminated in unit time Most of the drugs follow first order kinetics Zero orderlinear kinetics Rate of elimination remains constant irrespective of the plasma drug concentration. CL decreases with increase in plasma drug concentration Constant amount of the drug is eliminated in unit time
