Investigation of the Relevance of CYP3A4 Inhibition on the Pharmacokinetics of the Novel P2X3 Antagonist Filapixant: Results of In Vitro Explorations and a Fixed-Sequence Clinical Trial with Itraconazole in Healthy Volunteers.
International journal of molecular sciences ·doi:10.3390/ijms262010177

Hypersensitized P2X3 receptor signaling has been described to play a role in several disorders, including chronic cough. The goal of our in vitro and in vivo studies was to investigate the biotransformation and the influence of CYP3A4 inhib…
