I don't suggest crushing or chewing Ranitidine (Zantac) it will
not make them work any faster.
If it's the effervescent tablets follow the instructions
below.
The 25mg Zantac effervescent tablets should dissolved in
1teaspoon of water.
The 150mg Zantac effervescent tablets should be dissolved in
6-8ounces of water.
*make sure you mix it well & it's all dissolved before
consuming*
