After metabolism in the liver, what happens to drug metabolites?

• A. They are always more active than the parent drug
• B. They are deactivated before excretion without effect
• C. They retain the same level of activity as the parent drug
• D. They are synthesized back into the parent drug before excretion

Answer: (B)

The correct understanding is that drug metabolites typically undergo a process in which they are deactivated before excretion, reducing or eliminating their pharmacological activity. This deactivation is a crucial part of drug metabolism, allowing the body to efficiently prepare substances for elimination. The liver plays a vital role in metabolizing drugs, converting them into more water-soluble compounds that can be easily excreted by the kidneys. This deactivation is essential for reducing potential toxicity and ensuring that drugs do not linger in the body longer than necessary. Most metabolites are designed to have reduced activity compared to their original form, allowing for a more controlled and safe clearance from the body. In some instances, metabolites may have some residual activity, but this is not the general rule. The process ensures that the metabolites are less pharmacologically active, aiding in the safe removal of substances.
