Zantac or Pepcid for breast cancer?

Interesting article.....I've been on ranitidine for quite a while for reflux and was diagnosed with IDC in April.

Nope, TectonicShift. They are two distinctly different classes of drugs that address acid reflux by very different mechanisms. Zantac and Pepcid are what’s called “H2 agonists” or “H2 blockers.” Before these drugs were developed, antacids (calcium carbonate such as Tums or aluminum-based antacids like Maalox) were the standard of care--coating the esophagus, providing a barrier and the slightly alkaline character neutralized much of the acid. But they neither truly altered the acid nor prevented oversecretion of it. H2 blockers inhibit the hydrogen atoms in the hydrocholoric acid molecule and make the acid less irritating and inflammatory. Proton pump inhibitors, or PPIs (Prilosec, Prevacid, Nexium, Protonix, Dexilant and their respective generic versions) actually inhibit secretion of stomach acid, limiting it to the minimum necessary for digestion. But without sufficient stomach acid, certain nutrients aren’t effectively absorbed (e.g., calcium carbonate taken for bones is poorly-absorbed by those on PPIs, though it can still, via physical barrier mechanisms, temporarily relieve breakthrough heartburn). That’s why those of us on PPIs who need calcium supplements must take it in the form of the more expensive (and less pleasant) calcium citrate.

TM researcher confirmed that anything that reduces stomach acid, so PPIs or H2 blockers, will boost the effectiveness of TM. In that case picking one that might have other benefits for cancer seems like a reasonable idea for anyone on TM. I don't know anyone else who takes it but I'll leave the info here for anyone who might go searching in the future.
