Abstract:
The influence of amikacin on digoxin uptake by various rabbit tissues was investigated in vitro. 125J-digoxin was used and radioactivity was counted in a gamma scintillation counter. Amikacin decreases digoxin uptake by the renal tissue and this action is probably due to a displacing effect. On the contrary, amikacin increases digoxin uptake by striated and cardiac muscle. It is suggested that the latter action is due to a vasodilating effect of the aminoglycoside antibiotic that favors the microcirculation of the above tissues.
