Equate's Ranitidine is the only antacid that works for me. Even the brand name Zantac, which has the main ingredient of ranitidine, still does not work as well or as long as the Equate brand. Most people think Equate does not have quality products due to their prices. They actually have good quality items. Effectiveness It completely takes away my acid reflux in minutes. I find taking one in the beginning of the day keeps you good for about 12 hours. Ease of Use The pills are tiny, pink, circular, solid form doses. Very easy to swallow, no residue left over from the pill. Immediacy It works within 20 minutes.
