  • Examination of the phosphoinositide-specific phospholipase C activity in the perfused hearts revealed that isoproterenol stimulation was associated with a decrease in the membrane-associated enzymatic activity at physiological calcium concentrations. (ahajournals.org)
  • atropine
  • a However, experts state that isoproterenol is not a drug of choice in ACLS and should only be considered in this setting for treatment of symptomatic bradycardia unresponsive to atropine or as a temporary measure until pacemaker therapy can be instituted. (drugs.com)
  • In symptomatic cases, intravenous atropine or isoproterenol may transiently improve conduction. (wikipedia.org)
  • 2017
  • THURSDAY, Aug. 10, 2017 (HealthDay News) -- Increases in the price of nitroprusside and isoproterenol correlated with reductions in their use, according to a letter to the editor published online Aug. 9 in the New England Journal of Medicine . (doctorslounge.com)
  • increases
  • The value of isoproterenol therapy in shock has been questioned because the drug increases oxygen demand in the myocardium and other tissues to levels that may not be met by increased blood flow. (drugs.com)
  • Increases in the price of nitroprusside and isoproterenol correlated with reductions in their use, according to a letter to the editor published online Aug. 9 in the New England Journal of Medicine . (doctorslounge.com)
  • Umesh N. Khot, M.D., from the Cleveland Clinic, and colleagues examined the impact of price increases on physician prescribing for nitroprusside or isoproterenol using data from 47 hospitals in the Vizient (formerly University HealthSystem Consortium) database. (doctorslounge.com)
  • Exposure of the hearts to 0.1 microM isoproterenol for up to 1 minute was associated with significant (up to threefold) increases in phospholamban and troponin I phosphorylation, but there was no significant increase in 32P incorporation into phospholipids. (ahajournals.org)
  • However, longer exposure (2 minutes or more) to isoproterenol was associated with increases in the degree of 32P labeling of phosphatidylinositols and phosphatidic acid. (ahajournals.org)
  • Isoproterenol produced increases in GOT, LDH and .alpha. (eurekamag.com)
  • anesthesia
  • IV isoproterenol may be useful in bronchospasm occurring during anesthesia but must be administered with extreme caution, if at all, in patients receiving cyclopropane or halogenated hydrocarbon general anesthetics. (drugs.com)

  • Accordingly, regression equations were obtained allowing reasonably accurate prediction of exercise valvular gradients on the basis of the isoproterenol data. (ahajournals.org)
  • patients
  • The researchers found that the absolute number of patients treated with nitroprusside or isoproterenol decreased by 53 and 35 percent, respectively, from 2012 to 2015. (doctorslounge.com)
