Many oral forms of medications can be crushed and suspended in water to be given via a rectal catheter. The rectal route of administration is useful for patients with any digestive tract motility problem, such as dysphagia , ileus , or bowel obstruction , that would interfere with the progression of the medication through the tract.
In acute situations, in emergency medicine and intensive care medicine, drugs are most often given intravenously. This is the most reliable route, as in acutely ill patients the absorption of substances from the tissues and from the digestive tract can often be unpredictable due to altered blood flow or bowel motility.
Desglymidodrine (developmental code name ST-1059) is the active metabolite of the prodrug antihypotensive agent midodrine. [1] [2] [3] It acts as a selective α 1-adrenergic receptor agonist. [1] [2] [3] Desglymidodrine is formed from midodrine via deglycination. [1] [2] [3]
Administering medication rectally. Enteral administration is food or drug administration via the human gastrointestinal tract. This contrasts with parenteral nutrition or drug administration (Greek para, "besides" + enteros), which occurs from routes outside the GI tract, such as intravenous routes. Enteral administration involves the esophagus ...
A systematic review and meta-analysis conducted on clinical trials comparing the clinical use of droxidopa and midodrine have found that midodrine was more likely to cause supine hypertension than droxidopa in patients with NOH. Midodrine was also found to be slightly more effective at raising blood pressure but not statistically significantly.
Rectal suppositories are intended for localized or systemic action to relieve pain, constipation, irritation, inflammation, nausea and vomiting, fever, migraines, allergies, and sedation. [ 7 ] [ 8 ] If they cause inflammation, chronic use of suppositories may cause rectal stricture , [ 9 ] but overall this is a safe method of drug delivery.
A nutrient enema, also known as feeding per rectum, rectal alimentation, or rectal feeding, is an enema administered to provide nutrition in cases where normal eating is not possible. In modern medicine, nutrient enemas have been superseded by tube feeding and parenteral nutrition (intravenous feeding).
Rectal bulb syringe to administer smaller enemas. An enema, also known as a clyster, is an injection of fluid into the rectum or into lower bowel by way of the rectum. [1] The word enema can also refer to the liquid injected, [2] [3] as well as to a device for administering such an injection. [4]
