Use dihydroergotamine exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor. Dihydroergotamine can damage the heart and other organs if it is used too often. Dihydroergotamine should be used only to treat a migraine that is in progress.
The posterior pituitary is often termed the neurohypophysis because the hormones of this part of the pituitary are released directly from the axonal endings of their source neurons into the circulation (Figure 2.1).
Because the pituitary affects so many functions of the body, it is called the âmaster gland.â. There are two types of pituitary tumors: secretory (which make hormones) and non-secretory (which don't make hormones). Secretory tumors can cause various problems depending on the hormone that the tumor produces.
