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).
The pituitary is an important gland in the body and it is often referred to as the 'master gland', because it controls several of the other hormone glands (e.g. adrenals, thyroid). It is usually about the size of a pea and consists of two parts (often called lobes) - a front part, called the anterior pituitary and a back part, called the posterior pituitary.
