English to Polish Medical Medical: Pharmaceuticals medicines

'Antacid' is a popular over the counter medicine (or a type of medicines) for hearburn. Medical dictionary says 'związek zobojętniający kwas', but I wonder if there is any popular or colloquial expression to refer to this type of medication in Polish. There is brand Rennie Antacidum - which I guess is a similar thing, but it is a brand and not a common word.
