Interaction of Rifampin and Digitoxin

Archives of Internal Medicine, 1983
In a patient who had been receiving digitoxin therapy, the serum digitoxin level decreased markedly when rifampin was added to the therapeutic regimen. The serum digitoxin level returned to the pretreatment level when rifampin therapy was discontinued.

The effect of digitoxin on the electrocardiogram

American Heart Journal, 1952
Abstract This study would indicate that digotixin changes the order of repolarization in a predictable manner though in an unpredictable amount in both normal and abnormal hearts. The changes in S-T and T as well as Q-T c are best explained by acceleration of repolarization in subendocardial muscle, thus abolishing the normal ventricular gradient ...

Digitoxin Attenuates Heart Failure, Reduces Myocardial Hypertrophy, and Preserves the Calcium-Binding Proteins in Infarcted Rats

Journal of Cardiovascular Pharmacology and Therapeutics, 2019
We previously showed that digitoxin prolongs the survival of rats with heart failure due to myocardial infarction (MI). In this study, we evaluated the effect of digitoxin on myocardial structure, ventricular function, and proteins involved in calcium ...

Digitoxin-Induced Thrombocytopenia

International Archives of Allergy and Immunology, 1972
A case of digitoxin-induced thrombocytopenia is reported in a 76-year-old female patient who had been treated with digitoxin over a period of 5 years. This thrombocytopenia was associated with a moderate eosinophilia and clinical signs of severe digitalis intoxication.

Digitoxin Suppresses Store Operated Calcium Entry by Modulating Phosphorylation and the Pore Region of Orai1.

Current molecular medicine, 2019
BACKGROUND Store-operated calcium entry (SOCE), primarily mediated by Orai1 and stromal interaction molecule 1 (STIM1), is a major Ca2+ influx pathway that has been linked to human diseases including myopathy, epilepsy, immunodeficiency, and cancer ...

The cardioactivity of digitoxin metabolites

European Journal of Pharmacology, 1971
Abstract Using isolated atria, the positive inotropic action of digitoxin and digoxin was compared quantitatively with the cardiac action of metabolites found in guinea pigs. The bis- and monodigitoxoside of digitoxigenin and the monodigitoxoside of digoxigenin showed the strongest inotropic effect with respect to the affinity as well as the maximum ...

C12-Hydroxylation of Digitoxin

Nature, 1957
USING paper chromatographic methods it has been shown that, following digitoxin administration to rats, the urine contains small amounts of unchanged digitoxin together with larger quantities of two cardioactive metabolites previously designated metabolites C and G 1,2. Human urine collected for 12 hr. from normal adults after an oral dose of 1 mgm. of

Colorimetric assay of digitoxin

Journal of the American Pharmaceutical Association (Scientific ed.), 1948
A colorimetric method in which sodium beta-naphthoquinone-4-sulfonate (purified) is reacted with digitoxin in alkaline solution to form a purple color is proposed for the determination of digitoxin. The purple color quickly reaches a maximum and fades, but the addition of acetic acid at the time of maximum development changes the color to yellow and ...

Digitoxin bei hepatorenaler Insuffizienz

DMW - Deutsche Medizinische Wochenschrift, 2008
Serum digitoxin levels were measured during maintenance treatment with digitoxin, 0.1 mg daily i.v., in 12 patients under intensive postoperative care who had hepatorenal failure resulting from multiple organ failure. Thirteen patients in intensive care with comparable basic diseases served as controls; they had developed predominantly renal failure ...

Excretion Equations and Interpretation for Digitoxin [PDF]

Nature, 1957
DR. J. SWINTOSKY has made a valuable addition to the literature of urinary excretion equations by enabling a specific velocity constant, k, to be derived from the rate of urinary excretion. The meaning of k is not discussed and superficially it appears to depend only on excretion.
