title: Effect of short- and long-term administrations of some drugs on rat intestinal flora. Short communication.
abstract: Two schedules of treatment were adopted for an experimental evaluation of drug induced alterations in mid-small intestinal flora of normal rats. Test substances were given orally twice daily for 3 days at large doses and once daily for 30 days at lower doses. Indometacin, benzydamine, phenylbutazone, pheprazone, picosulfol, magnesium sulfate, tolbutamide, phenformin, dexamethasone acetate and prednisolone acetate were tested. Drug-induced alterations in rat intestinal flora resulted more evidently following multiple short-time treatments.
