Papaverine
Definition:
(n.) An alkaloid found in opium. It has a weaker therapeutic action than morphine.
Example Sentences:
(1) Isoproterenol [IC 50 approximately 1 X 10(-9) M], prostaglandins, dibutyryl cyclic AMP [IC 50 approximately 2 X 10(-5) M], papaverine, theophylline and 5' AMP were inhibitory in the assay, whereas dibutyryl cyclic GMP and the cholinergic stimulator carbamylcholine either stimulated or had no effect on mitosis.
(2) Our work demonstrates that the systemic availability or papaverine can be markedly affected by product formulation.
(3) The amplitude was 15-70% as large as the tonic component of the K-contracture induced by 40 mM K. Theophylline (10 mM), 0.1 mM papaverine and 1 microM isoprenaline nearly abolished, and 1 mM cAMP partly depressed the tonic contraction of K-contracture, whereas the tonic contraction induced by the test solution was unaffected.
(4) In these studies, it is shown that increasing concentrations of carbamylcholine (carbachol) result in a shift to the right of the dose-response curves to (-)-isoproterenol and (-)-soterenol and a reduction of the maximum degree of relaxation produced by these agonists relative to that produced by papaverine.
(5) Similar results were obtained with vincamine (Vi) but vincamine's bronchoconstriction was not completely inhibited by papaverine.
(6) Pressure above and below the stenosis was measured intra-arterially and flow related measurements were made at rest and during reactive hyperaemia in the dog, and following papaverine administration in patients.
(7) Total bacterial counts, nitrate-reducing bacteria and nitrite concentration were determined in fasting gastric juice before and after 4 weeks of treatment with a strong or with a mild antacid drug, a placebo preparation and the spasmolytic agent papaverine which is known to inhibit gastric evacuation.
(8) To assess the role of hydrostatic pressure in edema formation, we compared lung permeability-surface area products (PS) in papaverine-treated lungs given either protamine alone or PAF + protamine and tested the effect of mechanical elevation of Pmv on protamine-induced lung edema.
(9) 50 patients were treated eith carbocromen and 50 with papaverine as controls.
(10) Aminophylline and caffeine can mimic this effect; however, papaverine and 1-methyl-3-isobutylxanthine, at concentrations inhibitory to phosphodiesterase, are without effect on glucocorticoid receptor binding to DNA.
