Design
The pharmacist shirt for the one whose knowledge of cytochrome P450 3A4 is, at this point, extensive enough to warrant a tour — CYP3A4 World Tour, in black and dark grey for the clinical pharmacist or pharmacy student who has been around this enzyme long enough to know every substrate, inhibitor, and inducer on the setlist and could perform the whole show from memory.
CYP3A4 is responsible for metabolizing approximately 50% of all drugs. It is the most clinically significant enzyme in the entire cytochrome P450 system. It has visited your warfarin, spent time with your statins, and had a complicated relationship with grapefruit that nobody has fully recovered from. The tour continues. This shirt is the merch.
A perfect clinical pharmacist gift, pharmacy school graduation tee, or pharmacokinetics nerd shirt for the one who knows CYP3A4 like an old friend — because at this point, it basically is one.
