A New(-ish) Antacid Medication

from Knowledgeable Provider Hosted by Jody Marks, MSN, AGACNP-BC, FNP-BC

The new PCAB Voquenza (vonoprazan) is being marketed as a superior alternative to PPI therapy for acid-related conditions (GERD with or without erosive esophagitis, H. pylori eradication). Are these two mechanisms of action really that different? Jody investigates.

Weird Medicine: The Podcast Dr. Steve & Studio71 Since 2007, Weird Medicine has been "the first and still only uncensored medical show in broadcast radio history" on SiriusXM. Now, the same crew that continues to shock, horrify, entertain and inform the satellite airwaves is producing a weekly podcast! This is a medical show for people who would never listen to a medical show on the internet (or anywhere else). If you have a question you'd like answered on the show, call the voicemail line at 347 766 4323 (347 POO HEAD) any time. Remember, Weird Medicine: The Podcast is an entertainment show and Doctor Steve is not your doctor. Always double check anything you hear on this show with your regular medical provider(s). *Warning: Weird Medicine contains extreme language and may not be suitable for younger listeners (actually, it's pretty unsuitable for just about everyone, so listen at your own risk)* We wanna make the podcast even better, help us learn how we can: https://bit.ly/2EcYbu4 Explicit
