Premedication
From Wikipedia, the free encyclopedia
Premedication refer to a drug treatment given to a patient before a (surgical or invasive) medical procedure. These drugs are typically sedative or analgesic.
Premedication before chemotherapy for cancer often refers to special drug regimens (usually 3 drugs, eg dexamethasone, diphenhydramine and omeprazole) given to a patient hours or minutes before the chemotherapy to avert hypersensitivity reactions (allergic reactions).
