More facts about Generic Lasix (Furosemide 40 mg):

What is the drug that is sold under the name Lasix?

Lasix is the brand name owned by the pharmaceutical company Aventis. The same medication is known worldwide as Furosemide by the name of the active substance of the medication. It means that it is not produced only by Aventis but also by other drug manufacturers. This allows you to buy Lasix cheaper than the branded medication if you look for the so-called generics of the medication. It is possible because the medication was developed back in 1962 and the exclusive right of the company that first made it to continue making the medication without sharing the formula had already expired. The medication is used as an anti-swelling agent and as a hypotensive agent (blood pressure-lowering).

The medication is a loop diuretic that acts quite fast. Besides, it has a relatively potent and short-lived effect. The effectiveness of the medication depends on the fact whether it enters the tubules at the points of the lumens by anion transport mechanism. The diuretic effect occurs as a result of inhibiting the reabsorption of sodium chloride in this segment of the Henle loop.

The start of the diuretic action is within one hour after the pills intake. The average duration of the effect is from three to six hours. When taken orally, the medication is quickly absorbed from the stomach and the amount of the active substance in the body is around fifty-seventy percents. The medication penetrates the placenta and the breast milk.

The secondary effects of enhanced sodium excretion are due to the amplified urinary excretion (due to osmotically bound water) and increased distal tubular secretion of potassium. The washing out of calcium and magnesium ions also increases.

Furosemide causes a dose-dependent stimulation of renin-angiotensin-aldosterone. In heart failure, the medication use leads to an acute reduction in cardiac preload by narrowing the capacitive venous vessels. This early vascular effect is prostaglandin-alternating and involves an adequate kidney function with activation of renin-angiotensin and unharmed synthesis of prostaglandins. In addition, due to its natriuretic effect, Furosemide decreases vascular reactivity relative to catecholamines, increased in patients with arterial hypertension.

The antihypertensive efficacy of furosemide is explained by increased sodium washing out, reduced blood volume and decreased response of smooth muscle vessels to vasoconstrictor stimulation.

The onset of a diuretic effect is observed within fifteen minutes after the administration of a dose of the medication.

The dose-dependent enhancement of diuresis and natriuresis was observed during the clinical trials in healthy volunteers who received the medication in the dosages between 10 and 100 mg. The duration of the medication effect in healthy volunteers is around three hours after the use of the medication.

The medication is washed out from the body with urine and feces. The medication has a two-phase half-life that takes about two hours. In people with impaired liver or kidney function, the half-life time can be increased.

When is the use of the medication appointed?
