On this episode, I discuss the new medication vonoprazan and where it will likely be used in practice.

Vonoprazan is from a brand new class of medication called “PCAB”. I discuss this medication and its pharmacology in this podcast episode.

Drug interactions and cost are the two major downsides of this medication that will likely limit its use compared to the PPIs.

CYP3A4 inducers like rifampin, carbamazepine, and phenytoin should not be used with vonoprazan. They will reduce the effectiveness of vonoprazan.

On this episode of the podcast, I cover guanfacine pharmacology, adverse effects, drug interactions, and much more.

Guanfacine is a central acting alpha-2 agonist that has the brand names of Tenex and Intuniv.

Because of guanfacine’s mechanism of action, it suppresses the sympathetic response leading to a drop in pulse and blood pressure.

It is important to remind patients that the onset of action is slow in the management of ADHD with guanfacine. I discuss this further in this podcast episode.

Ranolazine (Ranexa) Pharmacology Podcast

Ranolazine is primarily used for chronic angina management. I discuss pharmacology, drug interactions, adverse effects, and more in this podcast episode.

Ranolazine is well known to have drug interactions. CYP3A4 is of major importance but there are other subtle drug interactions that are important.

QTc prolongation has been reported with ranolazine so it is important to recognize risk factors and other medications that may contribute to this concern.

Enzyme inducers like carbamazepine, phenytoin, and St. John’s wort are all associated with reducing the concentrations of ranolazine.
