Injection site reaction. Injection site reactions (ISRs) are reactions that occur at the site of injection of a drug. They may be mild or severe and may or may not require medical intervention. Some reactions may appear immediately after injection, and some may be delayed. [1] Such reactions can occur with subcutaneous, intramuscular, or ...
Biological response modifiers (BRMs) are substances that modify immune responses. They can be endogenous (produced naturally within the body) or exogenous (as pharmaceutical drugs), and they can either enhance an immune response or suppress it. Some of these substances arouse the body's response to an infection, and others can keep the response ...
Interferon beta-1a (also interferon beta 1-alpha) is a cytokine in the interferon family used to treat multiple sclerosis (MS). [5] It is produced by mammalian cells, while interferon beta-1b is produced in modified E. coli. [6] Some research indicates that interferon injections may result in an 18–38% reduction in the rate of MS relapses.
A TNF inhibitor is a pharmaceutical drug that suppresses the physiologic response to tumor necrosis factor (TNF), which is part of the inflammatory response.TNF is involved in autoimmune and immune-mediated disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa and refractory asthma, so TNF inhibitors may be used in their ...
However, there are risks associated with allergen immunotherapy as it is the administration of an agent the patient is known to be highly allergic to. Patients are at increased risk of fatal anaphylaxis, local reaction at the site of injection, or life-threatening systemic allergic reactions. [71]
The injection-site reactions can be mitigated by rotating injection sites or by using one of the medications that requires less frequent injections. Side effects are often onerous enough that many patients ultimately discontinue taking Interferons (or glatiramer acetate, a comparable disease-modifying therapies requiring regular injections).
Mepolizumab. Mepolizumab, sold under the brand name Nucala by GlaxoSmithKline, is a humanized monoclonal antibody used for the treatment of severe eosinophilic asthma, eosinophilic granulomatosis with polyangiitis, and hypereosinophilic syndrome (HES). [5] It recognizes and blocks interleukin-5 (IL-5), a signalling protein of the immune system ...
Epoetin alfa, sold under the brand name Epogen among others, is a human erythropoietin produced in cell culture using recombinant DNA technology. [8][9] Epoetin alfa is an erythropoiesis-stimulating agent. [8] It stimulates erythropoiesis (increasing red blood cell levels) and is used to treat anemia, commonly associated with chronic kidney ...
