4.1 MeSH Pharmacological Classification

Excipients

Usually inert substances added to a prescription in order to provide suitable consistency to the dosage form. These include binders, matrix, base or diluent in pills, tablets, creams, salves, etc. (See all compounds classified as Excipients.)


4.2 Absorption, Distribution and Excretion

In the small intestine, most triglycerides are split into monoglycerides, free fatty acids, and glycerol, which are absorbed by the intestinal mucosa. Within the epithelial cells, resynthesized triglycerides collect into globules along with cholesterol and phospholipids and are encased in a protein coat as chylomicrons. Chylomicrons are transported in the lymph to the thoracic duct and eventually to the venous system. The chylomicrons are removed from the blood as they pass through the capillaries of adipose tissue. Fat is stored in adipose cells until it is transported to other tissues as free fatty acids which are used for cellular energy or incorporated into cell membranes. When 14C-labeled long-chain triglycerides are administered intravenously, 25% to 30% of the radiolabel is found in the liver within 30 to 60 minutes, with less than 5% remaining after 24 hours. Lesser amounts of radiolabel are found in the spleen and lungs. After 24 hours, nearly 50% of the radiolabel has been expired in carbon dioxide, with 1% of the carbon label remaining in the brown fat. The concentration of radioactivity in the epididymal fat is less than half that of the brown fat.

After absorption, long- chain saturated fatty acids are transported mainly via the intestinal lymph as triglycerides. Fatty acids with 10 or less carbon atoms are transported mainly from the intestine via the portal blood vessels. There are also data indicating that unsaturated long-chain fatty acids are absorbed mainly via the lymph vessels.

The skin penetration enhancement of drugs by tricaprylin has been demonstrated in vivo using Wistar rats and in vitro using hairless female mice. ... The drug permeation ratio in the presence of triglycerides increased in the following order: Tricaprylin (C8) > Triolein (CI8) > Tributyrin (C4) > Triacetin (C2).
