Tpy6a [65]
I believe the answer is <span>c. absorption

</span>The phase of pharmacokinetic that happens in the intestine is when the drug absorbed. A person with old age will have lower intestine motility. This will increase the transit time which will increase the amount of drug absorbed.

Age could also influence others pharmacokinetic parameter(<span>excretion, distribution, metabolism) but it is related with another organ, not intestine.</span>
