Carbachol changes spike-generation properties of GH3 pituitary cells. 1987

B Hedlund, and J L Barker

Membrane effects of carbachol (50 microM) on GH3 pituitary cells were studied using whole-cell type electrophysiological techniques. Carbachol (50 microM) decreased the threshold for generation of spontaneous and current-induced action potentials and prolonged their duration. It is suggested that carbachol blocks potassium channels in GH3 pituitary cells, and that the effect is mediated via activation of muscarinic cholinergic receptors.

UI MeSH Term Description Entries
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.
