Absorption
Well absorbed orally, poorly absorbed rectally. Studies in humans and animals indicate glycerol is rapidly absorbed in the intestine and the stomach
Route of Elimination
Approx 7-14% of dose is excreted unchanged in the urine within 2.5 hr.
Volume of Distribution
Glycerin is distributed throughout the blood. Although glycerin generally does not appear in ocular fluids, it may enter the orbital sac when the eye is inflamed, with a consequent decrease in osmotic effect.
Data from studies in humans and animals indicate glycerol is rapidly absorbed in the intestine and the stomach, distributed over the extracellular space and excreted.

Glycerin is a substrate for synthesis of triacylglycerols and of phospholipids in the liver and adipose tissue. When fat metabolized as a source of energy, glycerol and fatty acids are released into the bloodstream. Circulating glycerin does not glycate proteins and does not lead to the formation of advanced glycation endproducts (AGEs). In some organisms, the glycerin component can enter the glycolysis pathway directly to provide a substrate for energy or glucose production. Glycerol must be converted to their intermediate glyceraldehyde 3-phosphate before being used in glycolysis or gluconeogenesis. Glycerol metabolism is regulated by the enzymes glycerol kinase, (cytosolic) NAD+-dependent G3P dehydrogenase and (mitochondrial) FAD-linked G3P dehydrogenase.
Glycerol is phosphorylated to alpha-glycerophosphate by glycerol kinase predominantly in the liver (80-90%) and kidneys (10-20%) and incorporated in the standard metabolic pathways to form glucose and glycogen. Glycerol kinase is also found in intestinal mucosa, brown adipose tissue, lymphatic tissue, lung and pancreas. Glycerol may also be combined with free fatty acids in the liver to form triglycerides (lipogenesis) which are distributed to the adipose tissues. The turnover rate is directly proportional to plasma glycerol levels.

Glycerol is endogenous in the human body. It enters the glycolytic pathway after its conversion in the liver to glycerol-3-phosphate by glycerol kinase. Glycerol-3-phosphate is then oxidized by glycerol-3-phosphate dehydrogenase to yield dihydroxyacetone phosphate, which is then isomerized to glyceral-dehyde-3-phosphate, eventually yielding pyruvic acid.

Glycerol esters are hydrolyzed to glycerol and the corresponding carboxylic acids. The hydrolysis is catalysed by intestinal lipase, which attacks the ester bonds at carbons 1 and 3. The ester bond at carbon 2 is more resistant to hydrolysis, possibly because of its stereochemistry and steric hindrance. The beta-monoglyceride can, however, spontaneously isomerise to the alpha-form (3-acylglycerol), permitting further hydrolysis to yield glycerol.

When administered rectally, glycerin exerts a hygroscopic and/or local irritant action, drawing water from the tissues into the feces and reflexively stimulating evacuation. Glycerin decreases intraocular pressure by creating an osmotic gradient between the blood and intraocular fluid, causing fluid to move out of the aqueous and vitreous humors into the bloodstream.
Glycerin (glycerol) and sorbitol are hyperosmotic laxatives.
American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011
When administered rectally, glycerin and sorbitol exert a hygroscopic and/or local irritant action, drawing water from the tissues into the feces and reflexly stimulating evacuation. The extent to which the simple physical distention of the rectum and the hygroscopic and/or local irritant actions are responsible for the laxative effects of some of these drugs is not known. Only extremely high oral doses of sorbitol (25 g daily) or glycerin exert laxative action.

The physicochemical effects of a series of alkanols, alkanediols and glycerol on erythrocyte shape and hemolysis at 4 and 20 degrees C were examined. We calculated the dielectric constant of the incubation medium, Ds, and the dielectric constant of the erythrocyte membrane Dm in the presence of organic solutes. The ratio Ds/Dm = -38.48 at 20 degrees C defines the normal biconcave shape in a medium without hemolytic agents. A decrease in Ds/Dm favors externalization or internalization with consequent hemolysis. Alkanols and alkanediols convert biconcave erythrocytes into echinocytes, which is accompanied by an increase in the projected surface area. Glycerol converts biconcave erythrocytes into stomatocytes, which was accompanied by a marginal decrease in the projected surface area. Progressive externalization in alkanols and alkanediols or internalization in glycerol resulted in a decrease in the projected surface area and the formation of smooth spheres. The degree of shape change induced was related to the degree of hemolysis and the ratio Ds/Dm. A decrease in temperature reduced both the degree of shape change and hemolysis. .../Thus/ physicochemical toxicity may be a result of a temperature dependent hydrophobic interaction between the organic solutes and the membrane and is best interpreted by the ability of the solutes to change Ds and Dm.
