Uses
Glatiramer Acetate-Dx is labelled Glatiramer Acetate (G406800) which is a random basic synthetic copolymer of L-alanine, L-lysine, l-glutamic acid and L-tyrosine. Glatiramer acetate is an immunomodulator used in treatment of multiple sclerosis.
Uses
Glatiramer acetate is a random basic synthetic copolymer of L-alanine, L-lysine, l-glutamic acid and L-tyrosine in a molar ratio of 6:1.9:4.7:1. Glatiramer acetate is an immunomodulator used in treatment of multiple sclerosis.
Manufacturing Process
Glatiramer Acetate is water soluble copolypeptide with molecular weight
15,000-25,000.
Copolymer is prepared by copolymerization of the N-carboxyanhydrides of
tyrosine, alanine, lysine, and glutamic acid. The polymerisation was carried
out at ambient temperature in anhydrous dioxane with diethylamine as
initiator. Glatiramer Acetate have the ratio alanin:glutamic acid:lysine:tyrosine
= 1:6:4.54:2.
brand name
Copaxone (Teva).
Therapeutic Function
Immunomodulator
Biological Activity
Glatiramer acetate, a myelin basic protein mimetic, is an immunomodulator used for treatment of Multiple Sclerosis. Glatiramer acetate is a mixture of synthetic peptides randomly composed of glutamic acid, lysine, alanine, and tyrosine. It reduces relapse rate and disease progression in Multiple Sclerosis. Its mechanism of action is not fully understood. Glatiramer acetate generates anti-inflammatory Th2 cells, which produce neurotrophic factors.
Clinical Use
Immunomodulating drug:
Treatment for patients at a high risk of developing
multiple sclerosis and for reduction in relapses in
ambulatory patients
Metabolism
A substantial fraction of a subcutaneous dose of
glatiramer is believed to be hydrolysed locally. Some of
the injected dose is also presumed to enter the lymphatic
system, either intact or partially hydrolysed.
