Intratekaalsed

Intratekal is a term used in medical and scientific contexts to describe substances that are introduced into the body through a vein or other intravascular route, as opposed to being ingested orally. The term is derived from the Latin words "intra" meaning "within" and "tekel" meaning "tax" or "assembly", with "kal" implying a relation to a vessel or tube, in this case, a blood vessel.

Intratekal substances are typically administered through a vein or injection, and are designed to target specific areas or systems within the body. This method of delivery allows for a quicker and more efficient absorption of the substance, compared to oral ingestion, where the substance must first be digested by the stomach and absorbed through the digestive tract.

Examples of intratekal substances include medications, such as painkillers and anesthetics, ions for total parenteral nutrition, fluids for hydration and electrolyte balance maintenance, among others. Intratekal therapy is commonly used in medical settings, including hospitals and clinics, to deliver treatment directly to the affected area or system.

The interest in intratekal substances in medical and veterinary practice is reflected in wide range of research, directed at the development of targeted drug delivery systems, increase patient safety and effective treatment protocols, including treatment duration, dosage, and side effect management, all contributing to disease management.
