    Details Below:
    Bumetanide is a loop diuretic, which acts by inhibiting re-absorption from the
    ascending limb of the loop of Henle in the renal tubule. It has an onset of
    action within 1 h of oral administration and a duration of action of about 6 h.
    With regular use the impact on frequency of diuresis after drug administration
    tends to decrease. One of the side-effects of bumetanide is the development
    of hypokalaemia. Potassium supplements are administered to counteract this
    unwanted effect. Loop diuretics are used in the management of heart failure
    as they provide a symptomatic relief from the oedema. They reduce circulat-
    ing blood volume and therefore decrease preload and afterload in the heart.
    They do not have an impact on disease progression. Had oedema been severe
    in AB on admission, changing bumetanide to an intravenous administration
    for a few days until oedema is decreased could have been an option.
