Blockade by SKF 525A of the rat sympathetic ganglia and the adrenal medulla. 1976

M K Krstić

SKF 525A (1.5-9 mg/kg), depending on the dose used, reduced or abolished the hypertensive effect of McN-A-343, DMPP and nicotine, but did neither noticeably affect the hypertensive effect of tyramine, adrenaline and noradrenaline, nor the hypotensive effect of acetylcholine and orciprenaline. It is concluded that SKF 525A blocks the rat sympathetic ganglia and the adrenal medulla. This blockade is non-specific. It is suggested that the blockade results from the stabilizing effect of SKF 525A on postsynaptic membranes of the sympathetic ganglia and the adrenal medulla.

D009125 Muscle Relaxants, Central A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in MULTIPLE SCLEROSIS.

D004837 Epinephrine The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.

D005725 Ganglia, Autonomic Clusters of neurons and their processes in the autonomic nervous system. In the autonomic ganglia, the preganglionic fibers from the central nervous system synapse onto the neurons whose axons are the postganglionic fibers innervating target organs. The ganglia also contain intrinsic neurons and supporting cells and preganglionic fibers passing through to other ganglia. Autonomic Ganglia,Ganglion, Autonomic,Autonomic Ganglion
