Minor

magnesium hydroxide lactulose

Applies to: magnesium hydroxide and lactulose

Preliminary data from studies in humans and rats suggest that nonabsorbable antacids given concurrently with lactulose may inhibit the reduction in colonic pH induced by lactulose. Theoretically, this may reduce the effectiveness of lactulose in the treatment of portal-systemic encephalopathy, which requires an acidic environment in the colon to promote extraction of ammonia from the blood as well as retention/elimination of ammonia as the ammonium ion. However, the clinical relevance of this interaction has not been fully elucidated.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
