Dexpanthenol is a derivative of a B complex vitamin called pantothenic acid and the injection is a sterile, nonpyrogenic, aqueous solution. The injection is indicated for use as a gastrointestinal stimulant. Additionally, Dexpanthenol is available in combination as a hair tonic to improve scalp health and hair growth, as a cream to calm redness and irritation of the skin, and as an anti-aging cream. This drug is not currently FDA approved for the aformentioned indications; however, it is currently approved for use in multivitamin infusion products.
Injection: Prophylactic use immediately after major abdominal surgery to minimize the possibility of paralytic ileus. Intestinal atony causing abdominal distention; postoperative or postpartum retention of flatus, or postoperative delay in resumption of intestinal motility; paralytic ileus.
Topical: This medication is used as a moisturizer to treat or prevent dry, rough, scaly, itchy skin and minor skin irritations (e.g., diaper rash, skin burns from radiation therapy).
Pantothenic acid is a precursor of coenzyme A, which serves as a cofactor for a variety of enzyme-catalyzed reactions involving transfer of acetyl groups. The final step in the synthesis of acetylcholine consists of the choline acetylase transfer of acetyl group from acetylcoenzyme A to choline. Acetylcholine is the neurohumoral transmitter in the parasympathetic system and as such maintains the normal functions of the intestine. Decrease in acetylcholine content would result in decreased peristalsis and in extreme cases adynamic ileus.
Mechanism of action
Dexpanthenol that are precursors of CoA protect cells and whole organs against peroxidative damage by increasing the content of cell glutathione.
