pharmacological experiments as a basis for the administration of digoxin in the horse.	it is shown that the concentration of ouabain necessary for 50 per cent inhibition of the na+k activated membrane atpase of red cells is similar in man and horse. this is taken to indicate that the two species have similar sensitivity towards cardiac glycosides in general. in five adult healthy horses plasma digoxin concentration was measured with a radioimmunoassay technique after a single intravenous injection of 1 mg/100 kg body weight digoxin. the half time of elimination was 23 h and the ap ...	1976	130670
