Pharmacodynamics
The use of a single oral administration of tilactase has been shown to be highly effective in decreasing the symptoms and hydrogen excretion of hypolactasia in tests of lactose H(2)-breath. The analysis has shown a decrease of approximately 80% in both malabsorbers and intolerants.The administration of tilacatase also decreases the presence of bloating and flatus.
Mechanism of Action
Lactose is the primary disaccharide found in dairy products. Tilactase is a type of lactase which is the enzyme that is in charge of the breakdown of lactose to glucose and galactose which can be used by the body. Basically, tilactase acts by replacing the missing lactase in the body and allows avoidance of the reach of lactose to the small intestine and the normal bacteria and thus, preventing the symptoms of the lactose intolerance. Once tilactase has metabolized the lactose, the metabolism products are reabsorbed by the normal process of digestion.
Absorption, Distribution and Excretion
Tilactase is not absorbed in the GI tract and thus the pharmacokinetic parameters related to absorption are not relevant.
Tilactase is completely eliminated in the feces either unchanged or as metabolites.
Tilactase is not absorbed and thus the volume of distribution is not relevant.
Tilactase is not absorbed and thus the clearance rate is not relevant.
Verwendung und Herstellung
Uses
A group of enzymes that catalyzes the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-galactosides. Deficiency of beta-Galactosidase A1 may cause GANGLIOSIDOSIS, GM1. [ChemIDplus] Available commercially as a catalyst to hydrolyze milk lactose into glucose and galactose; [REPROTOX]
Anwendungen
Verwendenβ-D-Galactose s the beta anomer of D-Galactose (G155250), the C-4 epimer of Glucose (G595000). D-Galactose is found in milk and sugar beets as well as being synthesized by the body.
