Pharmacotherapeutic group:antihypertensive agent combined (angiotensin II receptor antagonist + diuretic)

ATX: & nbsp

C.09.D.A.03 Valsartan in combination with diuretics

C.09.D.A Angiotensin II antagonists in combination with diuretics

Pharmacodynamics:

Co-Diovan ® is a combined antihypertensive drug that contains an angiotensin II receptor antagonist and a thiazide diuretic.

Angiotensin II is an active hormone of the renin-angiotensin-aldosterone system (RAAS) and is formed from angiotensin I with the participation of an angiotensin-converting enzyme (ACE). Angiotensin II binds to specific receptors located on cell membranes in various tissues.It has a wide range of physiological effects, including primarily both direct and indirect participation in the regulation of blood pressure (BP). Being a powerful vasoconstrictor, angiotensin II causes a direct pressor response. In addition, it stimulates the secretion of aldosterone and promotes the retention of sodium ions.

Valsartan - active and specific antagonist of angiotensin II receptors. It selectively blocks AT subtype receptors₁, responsible for the vasopressor effect of angiotensin II. Increase in blood serum angiotensin II concentrations due to blockade with valsartan AT₁-receptors can lead to stimulation of unblocked AT₂receptors, which counterbalances the vasopressor effects associated with the excitation of AT₁receptors.

Valsartan does not have any pronounced agonistic activity against AT₁receptors. The affinity of valsartan for AT subtype receptors₁approximately 20,000 times higher than to the AT subtype receptors₂.

As valsartan does not inhibit ACE that converts angiotensin I to angiotensin II and causes bradykinin destruction, the development of side effects associated with the accumulation of bradykinin is unlikely.

When valsartan was compared with an ACE inhibitor, the incidence of dry cough was significantly (p <0.05) lower in patients who received valsartan, than in patients receiving an ACE inhibitor (2.6% vs. 7.9%, respectively). In a clinical study involving patients who previously developed a dry cough with ACE inhibitor treatment, in valsartan treatment, this complication was noted in 19.5% of cases, with thiazide diuretic treatment in 19.0% of cases, while in the group of patients treated with an ACE inhibitor, cough was observed in 68.5% of cases (p <0.05). Valsartan does not interact and does not block the receptors of other hormones or ion channels that are important for the regulation of cardiovascular functions.

The action application point thiazide diuretics are distal convoluted renal tubules. When thiazide diuretics are applied to highly sensitive receptors in the distal tubules of the cortical layer of the kidneys, reabsorption of sodium ions (Na⁺) and chlorine (C1^-). Suppression of the co-transport system Na⁺ and C1^-, apparently, occurs due to competition for the sites of C1 ion binding^- in this system. As a result, the excretion of sodium and chlorine ions increases approximately to the same extent.As a result of diuretic action, a decrease in the volume of circulating blood plasma is observed, as a result of which the activity of renin, the secretion of aldosterone, the excretion of potassium by the kidneys and, consequently, the decrease in the potassium content in serum are increased.

Pharmacokinetics:

Valsartan

Suction

After ingestion of valsartan, its maximum concentrations in the blood plasma are reached in 2-4 hours. The average bioavailability is 23%.

When taking valsartan with food, the area under the concentration-time curve (AUC) decreases by 48%, although starting from about the 8th hour after taking the drug, the concentrations of valsartan in the blood plasma, both in the case of taking it on an empty stomach, and in case of reception with food, are the same. Decrease AUC, nevertheless, is not accompanied by a clinically significant decrease in the therapeutic effect.

Distribution

Valsartan is bound to a significant extent (by 94-97%) with serum proteins, mainly albumin.

Biotransformation / metabolism

Valsartan is not significantly biotransformation, only about 20% of the dose is excreted as metabolites. Valeryl-4-hydroxy valsartan is detected in blood plasma at low concentrations (less than 10% of AUC). This metabolite is pharmacologically inactive.

Excretion

The pharmacokinetic curve of valsartan is of a downward multiexponential character: (half-life - T_1/2α<1 h and T_1/2β about 9 hours). Valsartan is excreted through the intestine (about 83% of the dose) and kidneys (about 13% of the dose), mostly unchanged. The half-life of valsartan is 6 hours.

In the range of doses studied, the kinetics of valsartan is linear. With repeated use of valsartan, no changes in the kinetic parameters were noted. When taking valsartan once a day, cumulation is negligible.

The concentrations of valsartan in the blood plasma in women and men were the same.

Hydrochlorothiazide (HCTZ)

Suction

After oral intake of hydrochlorothiazide occurs quickly, the time to reach the maximum concentration (tc_max) - about 2 hours.

In the therapeutic range of doses, the average value AUC increases in direct proportion to the increase in dose. Simultaneous intake of HCTZ with food can lead to both an increase and a decrease in systemic availability in comparison with fasting, but the magnitude of these effects is small and does not have much clinical significance.When administered, the absolute bioavailability of hydrochlorothiazide is 70%.

Distribution

The pharmacokinetics of hydrochlorothiazide in the phases of distribution and excretion is described as a whole by a bi-exponential descending curve. The apparent volume of distribution is 4-8 l / kg. Binding to blood plasma proteins (mainly with albumins) is 40-70%. Hydrochlorothiazide also accumulates in erythrocytes in a concentration approximately three times that of plasma.

Biotransformation

HCTZ is eliminated almost unchanged.

Excretion

The half-life of the final phase is 6-15 hours. With repeated use of the drug kinetics of hydrochlorothiazide does not change, with the appointment of the drug once a day, the accumulation of the drug is minimal. More than 95% of the absorbed dose is excreted unchanged by the kidneys.

Valsartan / hydrochlorothiazide

When combined with valsartan, the system bioavailability of HCTZ is reduced by about 30%. Simultaneous reception of GTCT, for its part, does not have a significant effect on the kinetics of valsartan. The noted interaction has no effect on the effectiveness of the combined use of valsartan and GTC.In controlled clinical trials, the distinct antihypertensive effect of this combination was found, which exceeded the effect of each of the components separately, as well as the placebo effect.

Pharmacokinetics in selected patient groups

Patients aged ≥65 years

In some elderly patients AUC Valsartan was slightly larger than in young patients, but this was not clinically significant.

A few data suggest that in elderly patients (both healthy and patients with hypertension) systemic clearance of HCTZ is lower than in healthy young volunteers.

Patients with impaired renal function

It is not necessary to correct the dose of the drug in patients with a glomerular filtration rate of 30-70 ml / min.

Currently there is no data on the use of the drug Co-Diovan^® in patients with severe renal dysfunction (glomerular filtration rate <30 ml / min) and in patients receiving hemodialysis. Valsartan is not excreted by hemodialysis because of significant binding to plasma proteins. At the same time, hemodialysis can effectively remove HCTZ from the body.

In the presence of renal insufficiency, the average concentration peaks in plasma and the values AUC hydrochlorothiazide increases, and the rate of excretion decreases. In patients with impaired renal function from mild to moderate severity, the half-life increases almost twice.

Patients with impaired hepatic function

AUC valsartan in patients with lungs (5-6 points on the scale Child-Pugh) and moderate (7-9 points on the scale Child-Pugh) violations of liver function was 2 times more than in healthy volunteers. Currently, there is no data on the use of Kodiovan® in patients with severe liver function disorders (more than 9 on the Child-Pugh scale).

Since the dysfunction of the liver does not have a clinically significant effect on the pharmacokinetics of HCTZ, correction of its dose in patients with impaired liver function is not required.

Contraindicated use of the drug Co-Diovan® patients with severe (more than 9 points on the scale Child-Pugh) violations of liver function. In patients with obstruction biliary tract preparation Co-Diovan ® should be used with caution.

Indications:Arterial hypertension (patients who are shown combined therapy).

Contraindications:

- Hypersensitivity to valsartan, hydrochlorothiazide and other sulfonamide derivatives, or to anyone another component of the drug;

- Pregnancy and pregnancy planning, the period of breastfeeding;

- tsevere (more than 9 on the Child-Pugh scale) liver function disorder;

- anuria, severe renal dysfunction (glomerular filtration rate <30 ml / min);

- dEthnic age to 18 years (safety and effectiveness of the drug in this category of patients have not been established to date);

- simultaneous use with aliskiren in patients with type 2 diabetes mellitus.

Carefully:

If you have one of these diseases, always consult a doctor before using the drug.

Caution must be exercised while the use of the drug Ko Diovan® potassium salts, potassium-sparing diuretics, potassium-salt food substitutes as well as pharmaceuticals that may cause an increase in the potassium content of the blood (e.g., heparin).

Co-Diovan ® should be used with caution in patients with unilateral or bilateral stenosis of the renal artery or stenosis of the artery of a single kidney,accompanied by violations of water-electrolyte balance: Nephropathy accompanied by loss of salts, and prerenal (cardiogenic) renal dysfunction, in patients with hypokalemia, hypomagnesemia, hyponatremia, hypercalcemia. Caution should be exercised in patients with severe sodium deficiency and / or reduced circulating blood volume (bcc) (for example, those receiving high doses of diuretics), with moderate impairment of liver function, chronic heart failure (CHF) III-IV functional class by classification NYHA, mitral or aortic stenosis, hypertrophic obstructive cardiomyopathy, systemic lupus erythematosus, primary hyperaldosteronism, diabetes mellitus, hyperuricemia, hypercholesterolemia and hypertriglyceridemia, with obstructive diseases bile ducts and cholestasis, in patients with closed-angle glaucoma, as well as in patients after kidney transplantation.

Pregnancy and lactation:

Like any other drug that affects RAAS, Co-Diovan® should not be used in women planning a pregnancy.When appointing any drug that affects RAAS, the doctor should inform women of childbearing age of the potential danger of using these drugs during pregnancy.

The use of the preparation of Co-Diovan ® in pregnancy is contraindicated, since, given the mechanism of action of receptor antagonists for angiotensin II, the risk to the fetus can not be ruled out. The effect of ACE inhibitors (drugs that affect RAAS) on the fetus, if prescribed in the second and third trimesters of pregnancy, leads to damage and death of the fetus. According to the retrospective data, when using ACE inhibitors in the first trimester of pregnancy, the risk of having children with congenital defects increases.

There are reports of spontaneous abortions, malnutrition and renal dysfunction in newborns whose mothers, during pregnancy, valsartan. The introduction of thiazide diuretics, including HCTT, into the uterus cavity resulted in the development of jaundice or thrombocytopenia in the fetus or in the neonatal period, as well as in the development of other undesirable phenomena that are subsequently observed in adults.

If pregnancy is detected during treatment with Co-Diovan®, the drug should be discontinued as soon as possible. It is not known whether the valsartan in breast milk. In experimental studies it was shown that valsartan is excreted with the milk of lactating animals.

HCTZ penetrates the placenta, excreted in breast milk, therefore it is not recommended to use Ko-Diovan^®during lactation.

Dosing and Administration:

Before starting therapy with Co-Diovan®, water-electrolyte disturbances need to be corrected (see the sections "With caution" and "Special instructions"),

Co-Diovan® is prescribed 1 tablet orally once a day; The tablet should be swallowed whole, taken as with food, and on an empty stomach, washing down with liquid.

Depending on the clinical situation, the recommended daily dose is 1 tablet of the preparation Ko-Diovan® containing valsartan / hydrochlorothiazide in a dose of 80 + 12.5 mg, 160 + 12.5 mg, 160 + 25 mg, 320 + 12.5 mg or, at most, 320 + 25 mg. If necessary, 1 tablet 160 mg + 25 mg per day is prescribed (the maximum daily dose for hydrochlorothiazide). The maximum decrease in blood pressure is usually achieved in 2-4 weeks of therapy.

Patients with mild to moderate renal impairment (glomerular filtration rate> 30 mL / min) are not required to change the dose of the drug.

In patients with lungs (5-6 points on the Child-Pugh scale) and moderate violations of the liver function without concomitant phenomena of cholestasis, the dose of valsartan should not exceed 80 mg.

Use in children

The safety and effectiveness of the use of Co-Diovan® in children (under 18 years of age) have not been established to date.

Overdose:

Symptoms: with an overdose of valsartan, one can expect the development of a pronounced decrease in blood pressure down to depression of consciousness, vascular collapse and / or shock with a lethal outcome. In case of an overdose with hydrochlorothiazide, the following symptoms may appear: nausea, drowsiness, hypovolemia, as well as cardiac arrhythmias and muscle spasms caused by disturbance of the water-electrolyte balance.

Treatment: Symptomatic, the nature of which depends on the time elapsed since the time of taking the drug, and on the severity of the symptoms. In the event of a marked decrease in blood pressure, the patient should be laid, lifting his legs, for a period of time necessary for therapy, to take active measures to support the activity of the cardiovascular system, including regular monitoring of the heart and respiratory system,volume of circulating blood (BCC) and the amount of excreted urine.

Valsartan is not excreted by hemodialysis because of its significant binding to plasma proteins. At the same time for removal from the body of hydrochlorothiazide, hemodialysis is effective.

Interaction:

General drug interactions for valsartan and HCTZ

Medicines that should be avoided together:

Lithium preparations

With simultaneous use of lithium preparations with ACE inhibitors, angiotensin II receptor antagonists or thiazide diuretics, a reversible increase in the concentration of lithium in the blood serum and associated increased toxic effects were noted. The risk of toxic manifestations associated with the use of lithium drugs may be further increased with simultaneous use with the preparation of Co-Diovan®, since the renal clearance of lithium preparations is reduced by thiazide diuretics. In this regard, careful monitoring of lithium content in blood serum is recommended.

Medicines, the joint use of which requires caution:

Hypotensive drugs

It is possible to intensify the hypotensive effect when combined with other means that reduce blood pressure (ACE inhibitors, beta-adrenoblockers, slow calcium channel blockers, guanethidine, methyldopa, vasodilators, direct renin inhibitors, angiotensin II receptor antagonists).

Pressor amines

Possible weakening of the action of pressor amines (norepinephrine, epinephrine), which does not require the termination of joint application.

Non-steroidal anti-inflammatory drugs (NSAIDs), including selective inhibitors of cyclooxygenase-2 (COX-2)

It is possible to reduce the diuretic and hypotensive effect of the drug Co-Diovan® when used simultaneously with NSAIDs, for example, with derivatives of salicylic acid, indomethacin. Concomitant hypovolemia can lead to the development of acute renal failure.

Drug Interactions for valsartan

Medicines that should be avoided together:

Simultaneous use of angiotensin II receptor antagonists with other drugs that affect RAAS leads to an increase in the incidence of arterial hypotension, hyperkalemia, and renal dysfunction.It is necessary to monitor blood pressure, kidney function, and the content of plasma electrolytes when using Ko-Diovan® with other drugs that affect RAAS.

Simultaneous use of potassium-sparing diuretics, biologically active additives containing potassium; potassium-containing substitutes for edible salt; other drugs that increase the potassium content in the blood serum (for example, heparin) requires the observance of precautions, including the frequent determination of potassium in the blood.

Non-steroidal anti-inflammatory drugs (NSAIDs)

When valsartan is used simultaneously with NSAIDs (including selective inhibitors of COX-2), its hypotensive effect may be reduced. Simultaneous use of angiotensin II receptor antagonists and NSAIDs, especially in patients with impaired renal function and / or hypovolemia (including with diuretic therapy), can lead to the development of acute renal failure. If it is necessary to jointly use valsartan and NSAIDs (including COX-2 inhibitors) before starting treatment, it is necessary to evaluate the function of the kidneys and correct the disorderswater-electrolyte balance.

Protein-carriers

By the results of the study in vitro on liver cultures valsartan is a substrate for the carrier proteins OATP1B1 and MRP2. The simultaneous use of valsartan with inhibitors of the carrier protein OATP1B1 (rifampicin, ciclosporin) and with an inhibitor of the transporter protein MRP2 (ritonavir) can increase the systemic exposure of valsartan (maximum concentration in blood plasma C_max and the area of the pharmacokinetic curve AUC).

Lack of drug interaction:

There have been no clinically significant interactions with monotherapy with valsartan against the background of the following drugs: cimetidine, warfarin, furosemide, digoxin, atenolol, indomethacin, hydrochlorothiazide, amlodipine, glibenclamide.

Drug Interactions for HCTZ

Lithium

With simultaneous use with ACE inhibitors and diuretics, cases of a reversible increase in the plasma concentration of lithium and its toxic effect were reported. Studies of the joint use of HCTZ with valsartan and lithium preparations have not been conducted. Therefore, with the simultaneous use of hydrochlorothiazide and preparations containing lithium, it is recommended to monitor the concentration of lithium in the blood.

Other antihypertensive drugs

Thiazide diuretics increase the hypotensive effect of other antihypertensive drugs (including guanethidine, methyldopa, beta-blockers, vasodilators, slow calcium channel blockers, ACE inhibitors, angiotensin II receptor antagonists, renin inhibitors).

Curare like muscle relaxants

Thiazide diuretics, including hydrochlorothiazide, potentiate the action of nondepolarizing muscle relaxants. Drugs affecting the potassium content in the blood. The risk of hypokalemia caused by diuretics can be exacerbated by the simultaneous use of glucocorticosteroids (GCS), adrenocorticotropic hormone (ACTH), amphotericin, carbenoxolone, penicillin, acetylsalicylic acid or its derivatives and antiarrhythmic drugs.

Drugs affecting the sodium content in the blood

Hyponatremic effect caused by diuretics can be intensified with simultaneous use with antidepressants, antipsychotic, anticonvulsants, etc. Care should be taken when using HCTZ for a long time together with the above preparations.

Hypoglycemic agents

Thiazide diuretics may break tolerance to glucose, and therefore may require adjustment of insulin doses, and hypoglycemic agents for oral administration.

Cardiac glycosides

Hypokalemia and hypomagnesemia (undesirable effects of thiazide diuretics) can contribute to the development of cardiac arrhythmias in patients receiving cardiac glycosides.

NSAIDs

Simultaneous use of NSAIDs and HCTT can lead to a decrease in the diuretic and hypotensive effects of the latter. Concomitant hypovolemia can provoke the development of acute renal failure.

H and M-holinoblokatory

H and M-holinoblokatory (incl. atropine, biperidene) can increase the bioavailability of hydrochlorothiazide, which is associated with a decrease in gastrointestinal peristalsis and gastric emptying rate.

Accordingly, GI motility stimulants (cisapride) can reduce the bioavailability of hydrochlorothiazide. Anion exchange resins. The absorption of hydrochlorothiazide is disturbed in the presence of colestyramine and colestipol. Hydrochlorothiazide should be taken either 4 hours or 4-6 hours after taking these compounds.

Vitamin D and calcium salts

Simultaneous intake of hydrochlorothiazide with vitamin D or calcium preparations can lead to hypercalcemia due to increased reabsorption of calcium.

Cyclosporin

With the simultaneous use of hydrochlorothiazide and cyclosporine, the risk of hyperuricemia and exacerbation of the gout current increases.

Methyldopa

Hemolytic anemia has been reported with the simultaneous use of hydrochlorothiazide and methyldopa.

Pressor amines

HCTZ can reduce the body's response to the introduction of pressor amines (norepinephrine). The clinical significance of this interaction is insignificant and can not prevent their joint application.

Other types of interaction

The simultaneous use of thiazide diuretics, including hydrochlorothiazide, may lead to an increase in the frequency of hypersensitivity reactions to allopurinol; increased risk of side effects of amantadine; increase the hyperglycemic effect of diazoxide, reduce the excretion of drugs that have a cytotoxic effect (for example, cyclophosphamide, methotrexate), and potentiate their mielosuppressive effects.

Ethanol, barbiturates and narcotic drugs

Their combined use with hydrochlorothiazide can to potentiate the development of orthostatic hypotension.

Special instructions:

Co-Diovan® can be used as an initial therapy in patients who are most likely to require several drugs to achieve target blood pressure values. The choice of Ko-Diovan® for the initial treatment of hypertension should be based on an assessment of the relationship between potential benefits and risks.

Impaired liver function

Co-Diovan® is not used in patients with severe liver function disorders (more than 9 on the Child-Pugh scale), with bile duct obstruction and cholestasis should be used with caution.

Change in the content of electrolytes in blood serum

Thiazide diuretics, because of the ability to reduce the potassium and magnesium levels in serum, should be used with caution in patients with conditions accompanied by violations of the water-electrolyte balance: Nephropathy accompanied by loss of salts, and prerenal (cardiogenic) renal dysfunction.If there are clinical manifestations of hypokalemia (muscle weakness, paresis, changes in ECG parameters) treatment with Co-Diovan should be stopped. Before starting the use of the drug, it is necessary to correct hypokalemia and hypomagnesemia. All patients taking medications containing thiazide diuretics need regular monitoring of the content of plasma electrolytes, especially potassium.

When using Co-Diovan®, the ability of thiazide diuretics to cause hyponatraemia and hypochloraemic alkalosis, and also aggravate the existing hyponatraemia. Hyponatremia in these cases is rarely accompanied by neurologic symptoms. It is necessary to regularly monitor the sodium content in the blood plasma.

Deficiency in the body of sodium and / or volume of circulating blood

In patients with severe deficiency in the body of sodium and / or with a decrease BCC (for example, in patients receiving high doses of diuretics), in rare cases, a marked decrease in blood pressure with clinical manifestations may occur at the beginning of treatment with Co-Diovan®. Before the start of treatment should be corrected the content in the body of sodium and / or make up the BCC,otherwise, treatment should be started under strict medical supervision.

In the case of a pronounced decrease in blood pressure, the patient should be placed and, if necessary, an intravenous infusion of 0.9% sodium chloride solution. After stabilization of blood pressure, treatment with Co-Diovan® can be continued.

Stenosis of the renal artery

In patients with unilateral or bilateral stenosis of the renal artery or stenosis of the artery of a single kidney, taking Co-Diovan® may be accompanied by an increase in the concentration of urea and creatinine in the blood serum, so in such patients, the preparation of Co-Diovan® should be used with caution.

Chronic heart failure III-IV functional class (according to classification NYHA), including after a previous myocardial infarction.

In patients whose renal function depends on the state of RAAS (eg, patients with chronic heart failure), therapy with ACE inhibitors and angiotensin II receptor antagonists may be accompanied by oliguria and / or progressive azotemia, in rare cases with acute renal failure.

The examination of patients with circulatory failure and patients who underwent myocardial infarction should include a study of kidney function.

Systemic lupus erythematosus

There are reports of exacerbation and worsening of the course of connective tissue diseases (eg, systemic lupus erythematosus) with the use of thiazide diuretics, including GTC.

Other metabolic disorders

Thiazide diuretics, including HCTT, can cause a change in glucose tolerance, as well as an increase in the concentration of cholesterol and triglycerides in the serum. Reducing the clearance of uric acid can lead to hyperuricemia and the development of gout in predisposed patients.

Thiazide diuretics reduce the excretion of calcium by the kidneys and can cause a slight increase in calcium in the plasma in the absence of concomitant disorders of calcium metabolism. Expressed hypercalcemia with thiazide diuretic therapy (> 12 mg / dl) or not responding to withdrawal may indicate a concomitant metabolic disorder of calcium. In several patients with hypercalcemia and hypophosphatemia, long-term use of thiazide diuretics was determined by pathologicalchanges in parathyroid glands.

Hypersensitivity reactions

The occurrence of reactions hypersensitivity against the background of hydrochlorothiazide was most often noted in patients with allergic reactions and a bronchial asthma in the anamnesis.

Quincke's edema, including swelling of the larynx and vocal cords, leading to airway obstruction, and / or edema of the face, lips, pharynx and / or edema of the tongue, was seen in patients who received valsartan, some of these patients previously developed Quincke's edema on the background of taking other drugs, including ACE inhibitors. Taking Co-Diovan® in case of development of Quincke's edema should be immediately canceled, resumption of Co-Diovan® preparation is prohibited.

Acute attack of angle-closure glaucoma

Against the background of the use of hydrochlorothiazide there have been cases of transient myopia and acute development of closed-angle glaucoma. The risk factor for acute development of an angle-closure glaucoma may be anamnestic data on allergic reactions to sulfanilamide and penicillin.

Symptoms: sudden onset, sudden drop in vision or pain in the eye, usually occurring between a few hours and a week after the start of therapy.An untreated, closed-angle glaucoma can lead to persistent loss of vision.

The first step is to stop taking hydrochlorothiazide. Additional medication or surgical treatment may be required if intraocular pressure after drug withdrawal is not reduced.
