Gastrointestinal Iodinated Contrast Agents
2021Oral contrast agents are categorized as “positive” (radiodense) or “neutral” (water attenuation). Positive agents are administered to opacify the bowel lumen and thus to improve the differentiation of bowel from non-bowel structures. The two main classes of positive oral contrast agents are barium sulfate suspensions and water-soluble iodinated ...

Psychotropic agents in functional gastrointestinal disorders
Current Opinion in Pharmacology, 2008Functional gastrointestinal disorders (FGIDs) are common conditions diagnosed by established symptom-based criteria. Dysregulation of the brain-gut axis is emerging as the primary pathophysiologic mechanism for FGIDs; this opens avenues for newer treatment modalities.

Erythromycin as a gastrointestinal prokinetic agent
Intensive and Critical Care Nursing, 2001Erythromycin is a potent stimulator of gastrointestinal (GI) motility and can be a useful agent to treat GI stasis in patients who are critically ill. However, it is not licensed for this indication and has serious drug interactions which may limit its utility.

Gastrointestinal Toxicity of Chemotherapeutic Agents
Seminars in Oncology, 2006Chemotherapy-induced toxicities commonly occur in sites within the gastrointestinal (GI) tract and account for dose-limiting effects. These toxicities are major contributing factors to dose reduction, delays, and cessation of cancer treatment. Through intensive therapies including surgery, combination chemotherapy, hormonal therapy, and targeted ...

Effects of Pharmacological Agents on Gastrointestinal Motility
Veterinary Clinics of North America: Equine Practice, 1989The control mechanisms of gastrointestinal motility are complex. Extrinsic neurohormonal effects modulate an intrinsic system, often called the "gut brain," composed of nervous and neuropeptide components. To exert pharmacologic influence on GI motility, use is made of agents that mimic the external control system.

Influence of chelating agents on the gastrointestinal absorption of lead
Toxicology and Applied Pharmacology, 1975The effect of chelating agents given orally and parenterally in therapeutic doses (0.2 mmol/kg) on the gastrointestinal absorption of lead (50 mg/kg and 0.5 mg/kg) was investigated in female, 5- to 7-week-old rats using a method of radioactive 203Pb labeling.

Prokinetic agents for lower gastrointestinal motility disorders
Diseases of the Colon & Rectum, 1993Prokinetic agents are currently being investigated as potential therapies for motility disorders of the lower gastrointestinal tract. Cholinergic agonists such as bethanechol are known to improve postoperative ileus but are limited because of side effects. Dopamine antagonists such as domperidone appear to have maximal prokinetic effect in the proximal
