Drug metabolism plays important role that includes the conjugation of the drug molecule like glucorunide conjugation that helps in the excretion, it helps in the metabolic break down of the drug. Drug metabolism some time enhance the ability of drug to be excreted via urine by modifying the drug and they are involved in the detoxification of drug molecules.
Hence the correct option is : prolong the exposure of the drug molecule in the plasma.
Which of the following is NOT a role of drug metabolism? A conjugate another molecule onto...

Fatty Acid Metabolism. The reactions of the fatty acid spiral are shown below. Use the description on the left side of the page to classify the reactions and fill in the boxes on the right side of the page Activation Step. The activation of the fatty acid begins by the addition of CoA which will carry the fatty acid from the cytosol into the mitochondria. The product, which is a fatty acid with a CoA attached, is known as a...

25-25. Chromatography-mass spectrometry. Cocaine metabolism in rats can be studied by injecting the drug and periodically withdrawing blood to measure levels of metabolites by HPLC-mass spectrometry. For quantitative analysis, isotopically labeled internal standards are mixed with the blood sample. Blood was analyzed by reversed-phase chro- matography with an acidic eluent and atmospheric pressure chemical ionization mass spectrometry for detection. The mass spectrum of the collisionally activated dissociation products from the m/z 304 positive ion is shown in the figure on...
