Metabolism of 2022 FDAapproved small molecule drugs – Part 1 Does CYP3A4 still rule? By Julia Shanu-Wilson It won’t come as much surprise to learn that of the 17 small molecules* approved by the FDA in 2022, CYP3A4 was the major player in drug metabolism. References Iversen et al., Basic Clin Pharmacol Toxicol.
Metabolism of 2022 FDAapproved small molecule drugs part 2 Mixing it Up By Julia Shanu-Wilson In Part 1 of this topic we looked at metabolism of the small molecule drugs approved by the FDA in 2022 that were mediated by CYP3A4. 2008 Mar;153 Suppl 1(Suppl 1):S82-9.

An unfortunate fiction developed post- Buckman —particularly after Riegel v.
The drug at issue is the only FDA-approved pharmaceutical treatment for ATTR-CM (although off-label use of other drugs, and organ transplant, are sometimes used as treatments). 3 (2008), the court explained that “the word ‘includes,’ when used in a statute, ‘is usually a term of enlargement, and not of limitation.’” Pfizer, Inc. ,
