      Mechanism Gastric pH sensitive Gastric alkalinizer
      Key Mechanism Factor 1
Factor Name Gastric pH
Factor Description The normal pH range of gastric acid is between 1.5 and 3.5 and is highly acidic, consisting mainly of hydrochloric acid. Changes in the pH of the stomach can alter the absorption of drugs.
      Mechanism Description
  • Decreased absorption of Rosuvastatin due to altered gastric pH caused by Magnesium hydroxide 

Recommended Action
      Management Until further data are available, patients treated with rosuvastatin should probably avoid taking antacids or oral medications that contain antacids (e.g., didanosine buffered tablets or pediatric oral solution) for at least two hours before and after administration of rosuvastatin.
