Muscarinic receptor blockade by pirenzepine: effect on prolactin secretion in man. 1982

A Masala, and S Alagna, and L Devilla, and P P Rovasio, and S Rassa, and R Faedda, and A Satta

The effect of pirenzepine, a muscarinic receptor blocker which does not cross the blood brain barrier, on basal and TRH-stimulated prolactin (PRL) secretion in normal subjects was studied. Administration of 75 mg oral pirenzepine had no effects on prolactin levels in male subjects whereas it significantly reduced prolactin in females. No effect on TRH induced prolactin secretion was observed.

UI MeSH Term Description Entries
D008297 Male Males
D010879 Piperazines Compounds that are derived from PIPERAZINE.
D010890 Pirenzepine An antimuscarinic agent that inhibits gastric secretion at lower doses than are required to affect gastrointestinal motility, salivary, central nervous system, cardiovascular, ocular, and urinary function. It promotes the healing of duodenal ulcers and due to its cytoprotective action is beneficial in the prevention of duodenal ulcer recurrence. It also potentiates the effect of other antiulcer agents such as CIMETIDINE and RANITIDINE. It is generally well tolerated by patients.

D011388 Prolactin A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

D011950 Receptors, Cholinergic Cell surface proteins that bind acetylcholine with high affinity and trigger intracellular changes influencing the behavior of cells. Cholinergic receptors are divided into two major classes, muscarinic and nicotinic, based originally on their affinity for nicotine and muscarine. Each group is further subdivided based on pharmacology, location, mode of action, and/or molecular biology.

D011976 Receptors, Muscarinic One of the two major classes of cholinergic receptors. Muscarinic receptors were originally defined by their preference for MUSCARINE over NICOTINE. There are several subtypes (usually M1, M2, M3....) that are characterized by their cellular actions, pharmacology, and molecular biology.

D000929 Antidepressive Agents, Tricyclic Substances that contain a fused three-ring moiety and are used in the treatment of depression. These drugs block the uptake of norepinephrine and serotonin into axon terminals and may block some subtypes of serotonin, adrenergic, and histamine receptors. However, the mechanism of their antidepressant effects is not clear because the therapeutic effects usually take weeks to develop and may reflect compensatory changes in the central nervous system.
