Gastrointestinal Motility Effects

Gastrointestinal motility effects describe pharmaceutical impacts on stomach and intestinal muscle contractions affecting drug transit. Anticholinergic agents decrease motility delaying gastric emptying. Prokinetic agents enhance contractions accelerating transit. Opioids substantially reduce motility causing constipation. Motility changes alter drug absorption rate and extent.

Bioavailability assessment accounts for motility effects. Formulation strategies compensate for altered absorption. Dose adjustments address changed drug exposure. Regulatory submissions incorporate motility consideration. Patient counselling addresses constipation prevention.
