How the drug works

Combined antihypertensive drug (drug "Lorista") instruction describes the pharmacological action of each active component.

One of the active substances is losartan, acting as a selective antagonist of the enzyme type 2 angiotensin on the receptors of the non-protein structure.

Studies conducted in vitro and onanimal organisms, found that the action of losartan and its carboxyl metabolite is aimed at blocking the effects of angiotensin on angiotensin type 1 receptors. This activates renin in the blood plasma and causes a decrease in the concentration of aldosterone in the blood serum.

Causing an increase in the content of angiotensin type 2, losartan activates the receptors of this enzyme, while at the same time does not change the work of the enzyme kininase type 2, involved in the exchange of bradykinin.

The action of the active component of the drug "Lorista"is aimed at reducing the overall peripheral resistance of the vascular bed, pressure in the vessels of the small circle of blood circulation, postnagruzka, to provide a diuretic effect.

Losartan does not allow the development of a pathological increase in the heart muscle, it increases the resistance to the physical work of the human body, which has chronic heart failure.

Daily use of a single dose of losartancauses a steady decrease in upper (systolic) and lower (diastolic) blood pressure. During the day, under the action of this substance, the blood pressure is uniformly controlled, and the antihypertensive effect coincides with the natural circadian rhythm. The decrease in pressure at the time of completion of dosage of losartan occurs by 80% compared with the peak activity of the active component. With medication, there is no effect on the heart rate, and when you stop taking it, the symptoms of withdrawal do not develop. The effectiveness of losartan extends to the male and female body of all ages.

As part of a combination of actionhydrochlorothiazide as a thiazide diuretic is associated with impaired absorption of chlorine, sodium, magnesium, potassium and water ions in the primary urine back into the blood plasma of the distal kidney nephron. The substance enhances the retention of calcium ion and uric acid. Hydrochlorothiazide exhibits antihypertensive properties due to the expansion of arterioles. The diuretic effect begins after 60-120 minutes, and the maximum diuretic effect lasts from 6 to 12 hours. The optimal antihypertensive effect of drug treatment occurs after 1 month.

By reducing the amount of blood circulating throughvessels, during treatment with high doses of diuretics, the initial daily dose of losartan is used 25 mg at a time. Therefore, therapy with such antihypertensive drugs is possible only after the exclusion of diuretics and the normalization of blood volume.

On the drug "Lorista" (pills) instruction is notcontains information on the need to adjust the dose for elderly patients and for people undergoing hemodialysis, or for those with renal insufficiency with creatinine clearance from 30 to 50 ml per minute.

To reduce the likelihood of diseasecardiovascular system and the number of deaths in patients with arterial hypertension and pathological changes in the left ventricle, a standard initial dose of losartan per day is prescribed at 50 mg per dose. If blood pressure reduction results were not achieved at the initial dosage, it is necessary to increase up to 100 mg of losartan, which is possible when using 2 tablets of Lorista N or 1 tablet of Lorista ND per day at a time.

Some Patients are possible manifestations of unwantedeffects of treatment with this antihypertensive drug. When using the drug "Lorista" (tablets), instructions for use include a list of side effects associated with various systems of the body.

Hyperkalemia is contraindicated,refractory hypokalemia, water imbalance in the body during therapy with high doses of diuretics, severe liver function, increased pressure, deficiency of the enzyme lactase, glucose intolerance and galactose, pregnancy, breastfeeding, children and adolescents under 18 years of age.

Treatment with Lorista (tablets)the instruction prohibits in case of hypersensitivity to compounds of the sulfonamide series, to the substance losartan, hydrochlorothiazide, or auxiliary components of the drug.

Care is required when usingpatients with impaired water and electrolyte balance in the blood, when there are signs of hypochloraemic alkalosis, low content of sodium, potassium, magnesium ions and high concentrations of calcium ions in the human body.

Bilateral narrowing of the kidney arteries or narrowinglumen of an artery to a single kidney, diabetes mellitus, elevated levels of uric acid in blood plasma, deposition of urates in the joints, the presence in the past of allergic reactions to drugs that inhibit angiotensin-converting enzymes, bronchial asthma, systemic blood diseases serve as a reason for the careful use of antihypertensive medication.

Application features

During treatment with Lorista (tablets)instructions for use allows you to additionally take other antihypertensive drugs. For older people do not require special selection of the initial dosage.

The drug's actions can lead to an increase in serum creatinine and urea concentrations in patients who have bilateral renal artery stenosis or single kidney artery stenosis.

Under the influence of hydrochlorothiazide increasesarterial hypotension, electrolyte balance is disturbed, which is characterized by a decrease in circulating blood volume, hyponatremia, hypochloremic alkalosis, hypomagnemia, hypokalemia. The effect of the diuretic is aimed at increasing the concentration of cholesterol and triglycerides, changing the body's tolerance to glucose molecules, reducing the excretion of calcium ions in the urine, which leads to their increase in blood serum. Hydrochlorothiazide can cause hyperuricemia and gout.
