Synergistisk kombination af et stof med mavesyresekretionsinhiberende virkning og et syrenedbrydeligt antibiotikum

The invention consists of a combination of a substance that increases the intragastric pH and an acid degradable antibacterial compound. By this combined product regimen it will be possible to obtain maximal local antibacterial effect of acid degradable antibiotics as well as enhanced bioavailability of the active antibiotic, thus resulting in higher amounts of the active compound in the gastric mucosa due to secretion of weak bases. Both pharmacological effects contribute to drastically increased antimicrobial capacity of acid degradable antibiotics to be used against local infections in the gastrointestinal tract causing gastritis and/or peptic ulcer. The invention also selects to the use of said combination and a process for the preparation thereof.
