Lasix Retard uses


Pharmacological action

Lasix Retard is a loop diuretic. This medication violates the reabsorption of sodium and chlorine in the large segment of the ascending loop of Henle. Due to increasing separation of sodium ions occurs secondary increased excretion of water and increased secretion of potassium ions in the distal renal tubule. Simultaneously increased excretion of calcium and magnesium ions.

Lasix Retard has secondary effects caused by the release of neurotransmitters and intrarenal redistribution of intrarenal blood flow. On the background of a course of treatment does not occur the weakening effect.

When heart failure Lasix Retard quickly leads to a reduction of preload on the heart through the expansion of large veins. This drug exerts the hypotensive effect due to increased excretion of sodium chloride and reduction reactions of vascular smooth muscle to vasoconstrictor effects and by decreasing the BCC. Effect of Lasix Retard after IV injection occurs in 5-10 minutes; after oral administration within 30-60 minutes, a maximum of the action is after 1-2 hours, the duration of effect is 2-3 hours (if reduced kidney function - up to 8 hours).

Lasix Retard reduces the incidence of atrial natriuretic factor in the plasma, causing vasoconstriction.

Diuretic effect develops in 3-4 minutes after IV injection and lasts 1-2 h; after oral taking - 20-30 minutes, lasts up to 4 hours.

Pharmacokinetics

After oral administration absorption of Lasix Retard is 60-70%. In severe kidney disease or chronic heart failure, extent of absorption is reduced.

Vd is 0.1 L / kg. Binding to plasma proteins (mainly albumin) is 95-99%. Lasix Retard metabolized in the liver. Excreted by the kidneys is 88% with bile - 12%. T1/2 in patients with normal renal function and liver is 0.5-1.5 h. When anuria T1/2 can be increased up to 1.5-2.5 h, with concomitant renal and liver failure - up to 11-20 hours.

Using during pregnancy and breastfeeding

In pregnancy, the use of Lasix Retard is only possible within a short time only, when the intended use of therapy to the mother justifies the potential risk to the fetus.

As Lasix Retard may be excreted in breast milk and to suppress lactation, if necessary use during lactation, a breastfeeding should be discontinued.

Before the treatment by Lasix Retard it should be compensated for electrolyte disturbances. During treatment with Lasix Retard it is necessary to control blood pressure, electrolytes and glucose in the blood serum, liver and kidney function.

For the prevention of hypokalemia there is expedient to combine Lasix Retard with potassium-sparing diuretics. With the simultaneous administration of Lasix Retard and hypoglycemic agents it may be require dose adjustment of the latter.

Lasix Retard drug interactions

Aminoglycosides, ethacrynic acid and cisplatin increases ototoxicity of this medication (especially when impaired renal function). Lasix Retard increases the danger of kidney damage with amphotericin B. if prescribed high doses of salicylates increases the risk of salicylism (competitive renal excretion), cardiac glycosides - hypokalemia and related arrhythmias, corticosteroids - an electrolyte imbalance. Lasix Retard reduces muscle relaxant activity of tubocurarine, potentiates the effect of succinylcholine. This drug reduces the renal clearance (and increases the likelihood of intoxication) lithium. Under the influence of Lasix Retard increases the effect of ACE inhibitors and antihypertensive agents, warfarin, diazoxide, theophylline, attenuated - antidiabetic drugs, norepinephrine. Sucralfate and indomethacin (by inhibiting the synthesis of PG, the level of violations of plasma renin and aldosterone excretion) reduce the effectiveness of Lasix Retard Atlantic Laboratories. Probenecid increases the concentration of this medicine in serum (blocking excretion).
