The pronoun for antacids is Gas-Hwalmyeongsu.

I think the most effective digestive remedy is Kkaseu Hwalmyeongsu.
I often experience indigestion when I overeat, eat greasy foods, or eat quickly.

Whenever that happens, taking commonly purchased medication from the pharmacy helps alleviate the symptoms and makes you feel better.
If you don't go to the hospital unnecessarily and just take a bottle of Gas-Hwal-myeong-su, you'll feel better quickly.
Donghwa Pharmaceutical's Buchaepyo Gas Hwal Myeong Su, with a long history, is trustworthy and good.
Since it's a herbal ingredient, the effect is quick and seems to be better.

After looking at the ingredients of the medication, I was reassured because they are all safe components.

The definitive recommendation for antacids is Buchae Pyo Gas Hwal Myeong Su.
