Just venting.. While trying to keep myself medically informed I read this.. CYP3A4 is the most important of the CYP450 enzymes for drug metabolism and for drug interactions. It is not practi- cal to try to memorize the many CYP3A4 substrates, but it would be prudent to be familiar with the most common CYP3A4 inhibitors and inducers since such drugs are likely to interact with approximately half of all drugs on the market. https://www.pharmacytimes.com/view/drug-interactions-with-cyp3a4-an-update Why are the %*)($ computers on the doctor's desk programmed for billing, but not tracking these issues? https://youtu.be/nWjoNa8nXr4
