Glatiramer
Glatiramer is an immunomodulatory medication used to treat multiple sclerosis (MS), a condition where the immune system attacks the protective covering of nerves. It is thought to work by modifying immune processes and may act as a decoy to prevent the immune system from attacking myelin. It is primarily used in patients with relapsing forms of MS, including clinically isolated syndrome.
Glatiramer is an injectable disease-modifying therapy for multiple sclerosis that works by modifying immune processes believed to be involved in the disease.

Glatiramer is used to treat relapsing forms of multiple sclerosis (MS), including relapsing-remitting MS and clinically isolated syndrome (CIS). It helps reduce the frequency of MS relapses but does not cure the condition.
The exact mechanism is not fully understood, but glatiramer is thought to modify immune processes involved in MS pathogenesis. It may act as a decoy by mimicking myelin basic protein, potentially shifting the immune response away from attacking nerve coverings.
Glatiramer is administered as a subcutaneous injection. Common side effects include injection site reactions (redness, pain, or lumps) and a rare immediate post-injection reaction with symptoms like flushing, shortness of breath, or rapid heartbeat. Patients should be aware that it is not used for primary progressive MS. Storage and proper injection technique are important for effectiveness.
