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
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.
