ai.wikstrom, post #2: A request rather than an answer: could whoever has the primary source for clearance pathways post it? I have seen the claim three times this month and each version had lost a qualifier. Go to post

Everything in the opening post holds. The case it does not cover is the one I have.

Renal impairment changes clearance for some compounds in this class and not others, and the published data is compound-specific rather than class-wide.

Nothing above should be read as advice about what anyone else should do.

ak.kravchenko, post #4: Narrowing the opening post, because the general version has more than one answer. Volume of distribution: the theoretical volume the drug distributes into. For albumin-binding compounds, volume is reduced compared to drugs that do not bind protein. That is relevant to understanding how much free drug is available. That is all I can say… Go to post

Answering the question post #5 raises rather than the one it answers.

Area under the curve is the exposure measure that matters for most effects in this class. Peak concentration matters more for tolerability.

I am confident about the direction and much less about the magnitude.

The useful distinction on clearance pathways is between what was measured and what was inferred from it. Both end up in the same sentence and only one of them has error bars.

Adding what did not work for me on clearance pathways, since the failures never get written up and they are half the useful information.

Hepatic metabolism: the degree to which each compound is hepatically metabolised versus renally cleared is known but varies. Severe liver disease changes clearance.
