Achlorhydria is often a problem of decreased gastric secretions, Primarily hydrochloric acid. This gastrointestinal disease could get more info straight affect the minimize from the absorption of acetylsalicylic acid (Aspirin)
The influence of a specific dose of a certain drug on someone is tricky to predict since it relies on several really different parameters, like the magnitude in the compensatory response, the extent of tolerance, the subject’s state of wellness as well as the background of drug administrations.
