Loop diuretics interactions

Other drugs that may interact with cardiac glycosides include the following Albuterol, amphotericin B, beta-blockers, calcium, disopyramide, loop diuretics, nondepolarizing muscle relaxants, potassium-sparing diuretics, succinylcholine, sympathomimetics, thiazide diuretics, thioamines, and thyroid hormones.

These potent diuretic agents interact with almost the entire nephron, including Henle s loop (Fig. 7). Their primary effect is probably the inhibition of the active reabsorption of chloride ions, which then leads to the enhanced excretion of sodium ions and water. Plasma volume is reduced as a result of these effects, whereas in the long-term both cardiac preload and afterload will diminish. The metabolic side-effects of the loop diuretics are globally the same as those of the thiazides, with some incidental differences. Plasma renin activity increases by loop diuretic treatment and it can be well imagined that this effect is noxious in the long-term management of heart failure. The loop diuretics provoke a clearly... 

Many interactions with lithium have been described. Thiazide and loop diuretics decrease lithium excretion predisposing to serious lithium toxicity. Also non-steroidal anti-inflammatory agents, especially indomethacin can increase the risks for lithium toxicity due to decreased renal excretion.
