3) Vinca alkaloids, including vincristine, vinblastine, vinorelbine, and vindesine, are used to treat tumors such as Hodgkin lymphoma, testicular cancer, and non-small cell lung cancer. [3] These drugs inhibit the assembly of microtubules and thus disrupt axonal transport in the cell body of peripheral nerves.
This is primarily co-administered with L-DOPA to combat Parkinson's disease. Administration can prevent common side-effects, such as nausea and vomiting, as a result of interaction with D 2 receptors in the vomiting center (or cheomoreceptor trigger zone) located outside the blood–brain barrier .
It is given by injection into a vein. [2] Side effects may include irritation of the vein in which it is given, high blood sugar, and swelling. [2] [3] Excess use may result in low blood sodium and other electrolyte problems. [2] Intravenous sugar solutions are in the crystalloid family of medications. [4]
Peripherally selective drugs have their primary mechanism of action outside of the central nervous system (CNS), usually because they are excluded from the CNS by the blood–brain barrier. By being excluded from the CNS, drugs may act on the rest of the body without producing side-effects related to their effects on the brain or spinal cord .
Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system.Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies.
Checkpoint inhibitor therapy is a form of cancer immunotherapy. The therapy targets immune checkpoints, key regulators of the immune system that when stimulated can dampen the immune response to an immunologic stimulus. Some cancers can protect themselves from attack by stimulating immune checkpoint targets.
Chemoprevention or chemoprophylaxis refers to the administration of a medication for the purpose of preventing disease or infection. [1] [2] Antibiotics, for example, may be administered to patients with disorders of immune system function to prevent bacterial infections (particularly opportunistic infection). [3]
Cancer cell membranes have about sixteen times more insulin and IGF receptors than normal cells, and these receptors react with synthetic insulin. When insulin is administered, the cancer starves for glucose and generates enzyme activity that makes the cell membrane more permeable. The chemotherapy drug gets absorbed by the cancer.
