Chemotherapy is being given to a 55-year-old woman with metastatic cancer. Due to extreme nausea and vomiting, she makes a threat to cease the treatment. Prochlorperazine will be used by the oncologist to lessen the nausea and vomiting brought on by chemotherapy drugs. What is the prochlorperazine's mode of action?
Numerous medications have been discovered to be helpful in the prevention and treatment of vomiting, particularly vomiting brought on by cancer chemotherapy. Most neuroleptic medications, with the exception of thioridazine, have antiemetic properties that are mediated by inhibiting D2 dopaminergic receptors in the chemoreceptor trigger zone of the medulla. The first medications that were proven to be effective antiemetic medications and function by inhibiting dopamine receptors are phenothiazines, such as prochlorperazine.
Which condition from the list below exemplifies a type III hypersensitivity reaction?
Immune complex deposition mediates a type III hypersensitivity reaction. Auto-antibody complexes are generated in lupus and are then deposited in various tissues, including the kidneys, skin, and joints. Although they are examples of type II reactions, Graves disease and myasthenia gravis are classified as type V reactions in some classification schemes. In Graves, the thyroid's TSH receptors are targeted by auto-antibodies, whereas in Myasthenia, the acetylcholine receptor is the target. Due to the fact that T lymphocytes are directed against thyroid antigens and antibodies are also generated, Hashimoto's thyroiditis is typically seen as an illustration of a combination of type II and IV reactions. A typical instance of a type I, IgE mediated reaction is allergic rhinitis.
