Additional components: sodium chloride, water for injection.
Mannitol is available as an infusion solution, packaged in 200 or 400 ml glass bottles.
The drug has a significant diuretic effect.
Pharmacodynamics and pharmacokinetics
Mannitol is osmotic diureticable to retain fluid in the renal tubules and increase urine volume, which is made possible by high pressure blood plasma and the filtration process occurring in the renal glomeruli without causing tubular reabsorption. The effect of the drug mainly extends to the proximal tubule. But to some extent affects the descending loop of the nephron and the collecting ducts.
The substance does not penetrate tissue or cell barriers, does not increase the concentration of residual nitrogen in the composition blood. With an increase in the osmolarity of blood plasma, fluid moves from some tissues to the vascular bed. Diuresis is accompanied by a moderate increase in natriuresis, without causing a significant effect on the excretion of potassium. The concentration, i.e. the dosage of the substance, affects the increase in the diuretic effect. The drug is not used for patients with impaired renal filtration function, azotemiafollowed by cirrhosis of the liver, ascites, as the volume of circulating blood may increase.
Determined that mannitol It has poor absorption from the digestive tract, so it is created in the form of a solution for intravenous administration. In the body, the distribution of the substance occurs in the extracellular sector with a concentration of about 3 hours. Low metabolism mannitol occurs in the liver, resulting in glycogen formation. The half-life is approximately 1.5 hours. From the body, the drug is excreted by the kidneys.
Indications for use
Mannitol is prescribed for:
- brain edema, intracranial hypertensionaccompanied by renal or renal hepatic insufficiency;
- oliguriawith acute renal or renal hepatic impairment, while maintaining the filtration ability of the kidneys - in complex therapy;
- post-transfusion complications after poor blood compatibility;
- forced diuresiscaused by poisoning barbituratesor salicylates;
- prevention hemolysis during operations using extracorporeal circulation to prevent kidney ischemia and possible acute renal failure.
You should abandon the use of the drug with:
- increased sensitivity to him;
- anuriacaused by acute renal tubule necrosis;
- left ventricular failure;
- hemorrhagic stroke;
- subarachnoid hemorrhage;
- dehydration severe degree;
- hyponatremia, hypochloremiaand hypokalemia.
With caution, the solution is prescribed to women with lactation and of pregnancy, elderly patients.
When taking Mannitol, dehydration may develop, accompanied by dry skin and mouth, thirst, dyspepsiamuscle weakness spasms, hallucinations, lowering blood pressure. In addition, there may be a violation in the water-electrolyte metabolism, tachycardiapain behind the sternum, skin rash and thrombophlebitis.
Instructions for use Mannitol (Method and dosage)
As the instructions for use of Mannitol indicate, the solution is administered by drip or slow stream intravenously.
When conducting preventive measures, the dosage is calculated at 0.5 g per kg of patient weight. The therapeutic dose is 1.0-1.5 g per kg of weight and cannot be higher than 140-180 g.
Before administration, the solution is preheated to 37 ° C. If operations are performed with cardiopulmonary bypass, then the drug is introduced into the device at a dosage of 20-40 g before perfusion.
At oliguria pre-administered a test dose, intravenously drip. Then the patient's condition is controlled for about 2-3 hours. If the rate of diuresis does not increase to 30-50 ml / h, then the use of the drug is stopped.
Cases of overdose are caused not only by the use of the drug in elevated doses, but also by its rapid administration. It may develop hypervolemia, rise intraocularor intracranial pressure, load on the heart and so on.
The simultaneous use of the solution with other diuretic drugs can significantly enhance the mutual effect of each diuretic. The combination of the drug with Neomycin causes an increase in ototoxic or nephrotoxic effect. Mannitol may also increase the development of toxic effects when taken together with cardiac glycosides.
The presence of left ventricular failure requires a combination mannitol with high-speed loop diuretics, since the development of pulmonary edema is not excluded. In this case, you need to control blood pressure, diuresis and the concentration of potassium and sodium in the blood serum.
If drug administration causes headache, vomiting, dizziness, visual impairment, then the use of Mannitol is stopped in order to prevent the development of complications in the form of subdural and subarachnoid bleeding.
The appearance of symptoms of dehydration requires the introduction of additional fluid. Allowed for use in heart failure, in combination with "loop" diuretics, encephalopathy and hypertensive crisis.
Mannitol is reintroduced under close monitoring of the water-electrolyte balance of the blood composition.
