Effects of digoxin and acetyl-digitoxin on basal and CO2-stimulated ventilation. 1985

P H Joubert, and W J du Plooy, and J Booyens, and M Fata

Eight healthy volunteers were studied to ascertain the effect of digoxin and the relatively more lipophylic cardiac glycoside, acetyl-digitoxin on ventilation. Baseline ventilation as well as the response to the inspiration of 2.2% and 4.8% carbon dioxide were assessed. Digoxin produced a depression of minute volume and oxygen consumption whereas acetyl-digitoxin produced the opposite effect. This could be the result of a relatively greater vagomimetic effect with digoxin and a greater symphatomimetic effect with acetyl-digitoxin. These findings might have clinical implications in cardiac patients who have pulmonary disease.

D010101 Oxygen Consumption The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346) Consumption, Oxygen,Consumptions, Oxygen,Oxygen Consumptions
D012119 Respiration The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration ( Breathing
D002245 Carbon Dioxide A colorless, odorless gas that can be formed by the body and is necessary for the respiration cycle of plants and animals. Carbonic Anhydride,Anhydride, Carbonic,Dioxide, Carbon
D004074 Digitoxin A cardiac glycoside sometimes used in place of DIGOXIN. It has a longer half-life than digoxin; toxic effects, which are similar to those of digoxin, are longer lasting.

D004077 Digoxin A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small.

D000112 Acetyldigitoxins Cardioactive derivatives of lanatoside A or of DIGITOXIN. They are used for fast digitalization in congestive heart failure. Desglucolanatosides A,Acedoxin,Acetyldigitoxin,Adicin,Digitoxin Monoacetate,alpha-Acetyldigitoxin,Monoacetate, Digitoxin,alpha Acetyldigitoxin
D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
