Active ingredients in V04CG

Active Ingredient Description
Histamine

Histamine/IL-2 is an immunotherapy which aims to induce immune-mediated destruction of residual myeloid leukaemic cells and thereby to prevent relapse of leukaemia. The role of histamine is to protect lymphocytes, in particular NK cells and T cells, which are responsible for the immune-mediated destruction of residual leukaemic cells.

Methylthioninium chloride

In vivo, in low concentration, methylthioninium chloride speeds up the conversion of methaemoglobin to haemoglobin. Methylthioninium chloride has been observed to stain tissues selectively.

Pentagastrin

Pentagastrin is a synthetic polypeptide that has effects like gastrin when given parenterally. It stimulates the secretion of gastric acid, pepsin, and intrinsic factor, and has been used as a diagnostic aid as the pentagastrin-stimulated calcitonin test. Pentagastrin binds to the cholecystokinin-B receptor, which is expressed widely in the brain. Activation of these receptors activates the phospholipase C second messenger system. When given intravenously it may cause panic attacks.
