Mianserin potentiates responses to acetylcholine in the rat anococcygeus muscle. 1979

S A Doggrell

In the rat anococcygeus muscle, mianserin (1 and 10 muM) increased the magnitude of the maximal contractile responses to acetylcholine and carbamylcholine without affecting the maximal responses to (--)-noradrenaline. The potentiating effect of mianserin on responses to acetylcholine was maintained in the presence of 5muM phentolamine, following 6-hydroxy dopamine incubation of the tissues (1 mM for 3h) and in the presence of 1 muM nortriptyline. It is suggested that mianserin increases the sensitivity to acetylcholine by an action at the level of, or distal to, the cholinergic receptor.

D008803	Mianserin	A tetracyclic compound with antidepressant effects. It may cause drowsiness and hematological problems. Its mechanism of therapeutic action is not well understood, although it apparently blocks alpha-adrenergic, histamine H1, and some types of serotonin receptors.

D009119	Muscle Contraction	A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.
