Clinical-Pharmacological Group

Antihypertensive drug

Pharmacotherapeutic Group

Antihypertensive combination agent (slow calcium channel blocker + angiotensin II receptor antagonist + diuretic)

Pharmacological Action

Combined antihypertensive drug containing three components with complementary mechanisms of blood pressure control: amlodipine (calcium channel blocker), valsartan (angiotensin II receptor antagonist) and hydrochlorothiazide (thiazide diuretic). The combination of these components leads to a more pronounced decrease in blood pressure compared to monotherapy with each drug separately.

Amlodipine – a dihydropyridine derivative, a calcium channel blocker. It has antianginal and antihypertensive effects. It inhibits the transmembrane transition of calcium ions into cardiomyocytes and vascular smooth muscle cells. The antihypertensive effect of amlodipine is due to a direct relaxing effect on vascular smooth muscle cells. The mechanism of the antianginal action of amlodipine is not fully understood, it is presumably associated with the following effects: it causes dilation of peripheral arterioles, reducing total peripheral resistance (afterload), which leads to a decrease in myocardial oxygen demand; it causes dilation of coronary arteries and arterioles in both intact and ischemic areas of the myocardium, which increases oxygen supply to the myocardium, including in patients with Prinzmetal’s angina. Amlodipine reduces the severity of left ventricular hypertrophy. It does not affect myocardial contractility and conductivity, does not cause a reflex increase in heart rate, inhibits platelet aggregation, increases glomerular filtration rate, and has a weak natriuretic effect.

In patients with arterial hypertension, taking amlodipine once a day provides a clinically significant reduction in blood pressure (in supine and standing positions) for 24 hours. The antihypertensive effect develops slowly, so the development of acute arterial hypotension is not typical. In patients with angina, taking amlodipine once a day increases exercise tolerance, time to onset of angina attack and to ischemic ST segment depression, reduces the frequency of angina attacks and the need for nitroglycerin intake (short-acting forms).

The clinical efficacy of amlodipine has been proven in patients with stable exertional angina, vasospastic angina and angiographically confirmed coronary artery disease.

Amlodipine does not have an undesirable effect on lipid metabolism and does not cause changes in the plasma lipid profile. Amlodipine can be used in patients with bronchial asthma, diabetes mellitus and gout.

After a single oral dose, the effect of amlodipine begins in 2-4 hours and lasts for 24 hours. The maximum hypotensive effect is achieved no earlier than 4 weeks from the start of taking the drug. The hemodynamic effects of the drug remain unchanged with long-term use.

Valsartan – a selective angiotensin II receptor antagonist (type AT₁) for oral administration. It selectively blocks AT₁ subtype receptors, which are responsible for the effects of angiotensin II. The increase in plasma concentration of angiotensin II due to blockade of AT₁ receptors under the action of valsartan may stimulate unblocked AT₂ subtype receptors, which counteract the effects when AT₁ receptors are stimulated. Valsartan does not have agonistic activity towards AT₁ receptors. The affinity of valsartan for AT₁ subtype receptors is approximately 20,000 times higher than for AT₂ subtype receptors.

Valsartan does not interact with and does not block receptors of other hormones or ion channels involved in the regulation of cardiovascular functions.

Valsartan does not inhibit ACE, also known as kininase II, which converts angiotensin I to angiotensin II and breaks down bradykinin. Due to the lack of effect on ACE, the effects of bradykinin or substance P are not potentiated, so the development of dry cough is unlikely when using angiotensin II receptor antagonists. It has been proven that the frequency of dry cough during treatment with valsartan is significantly lower than when using ACE inhibitors. In the treatment of arterial hypertension, Valsartan reduces blood pressure without affecting heart rate.

After oral administration of a single dose of valsartan, the hypotensive effect develops within 2 hours, the maximum decrease in blood pressure is achieved within 4-6 hours. The antihypertensive effect of valsartan persists for 24 hours after its administration. With repeated use of valsartan, the maximum decrease in blood pressure, regardless of the dose, is achieved after 2-4 weeks and is maintained at the achieved level during long-term therapy. Sudden discontinuation of valsartan is not accompanied by a significant increase in blood pressure or other adverse events (withdrawal syndrome).

The use of valsartan in patients with chronic heart failure (NYHA functional class II-IV) leads to a significant reduction in the number of hospitalizations for cardiovascular diseases (which is especially pronounced in patients not receiving ACE inhibitors or beta-blockers). When using valsartan in patients with left ventricular failure (with stable hemodynamic parameters) or with impaired left ventricular function after myocardial infarction, a reduction in cardiovascular mortality is noted.

Hydrochlorothiazide – a thiazide diuretic, the diuretic effect of which is associated with impaired reabsorption of sodium, chloride, potassium, magnesium, water in the distal nephron; delays the excretion of calcium ions, uric acid. It has antihypertensive properties; the hypotensive effect develops due to the expansion of arterioles. It has practically no effect on normal blood pressure levels.

Excretion of electrolytes and water begins approximately 2 hours after administration, the maximum effect is achieved in 3-6 hours and lasts for 6-12 hours. The antihypertensive effect is achieved in 3-4 days of treatment and lasts for 1 week after completion of the drug intake. With long-term treatment, a decrease in blood pressure is achieved with the use of lower doses than those necessary for a diuretic effect. The decrease in blood pressure is accompanied by a slight increase in glomerular filtration rate, vascular resistance of the renal bed and plasma renin activity.

Hydrochlorothiazide, when taken once in high doses, leads to a decrease in plasma volume, glomerular filtration rate, renal blood flow and mean blood pressure. With long-term use in small doses, plasma volume remains reduced, while minute volume and glomerular filtration rate return to the baseline level preceding the start of treatment. Mean blood pressure and systemic vascular resistance remain reduced. Thiazide diuretics may interfere with breast milk production.

Pharmacokinetics

The pharmacokinetic parameters of amlodipine, valsartan and hydrochlorothiazide are linear.

Amlodipine

After oral administration, Amlodipine is slowly and almost completely absorbed from the gastrointestinal tract. Simultaneous food intake does not affect the absorption of amlodipine. C_max in plasma is reached after 6-12 hours after administration. The mean absolute bioavailability is 64-80%. The mean V_d is 21 L/kg of body weight, indicating that most of amlodipine is in the tissues, and a smaller part is in the blood. Most of the amlodipine in the blood (97.5%) is bound to plasma proteins. C_ss in plasma are reached after 7-8 days of constant amlodipine intake. Amlodipine crosses the blood-brain barrier and the placental barrier.

Amlodipine undergoes slow but active metabolism in the liver in the absence of a significant first-pass effect through the liver. Metabolites do not have significant pharmacological activity.

After a single dose of amlodipine, T_1/2 ranges from 35 to 50 hours, with repeated use it is approximately 45 hours. About 60% of the orally administered dose is excreted by the kidneys mainly in the form of metabolites, 10% – unchanged, 20-25% – through the intestine with bile. The total clearance of amlodipine is 0.116 ml/s/kg (7 ml/min/kg, 0.42 L/h/kg). Amlodipine is not removed by hemodialysis.

Prolongation of T_1/2 in patients with hepatic insufficiency suggests that with long-term use, the accumulation of amlodipine in the body will be higher (increases to 60 hours).

Valsartan

After oral administration of valsartan, C_max is reached after 2-3 hours. The mean absolute bioavailability is 23%. When taking valsartan with food, a decrease in bioavailability (by AUC value) of about 40% is noted, and C_max – approximately 50%. Approximately 8 hours after oral administration, plasma concentrations of valsartan in the group of patients taking the drug with food and in the group taking the drug on an empty stomach level off. The reduction in AUC is not clinically significant, so Valsartan can be taken regardless of food intake.

V_d of valsartan at steady state after IV administration is about 17 L, indicating no extensive distribution of valsartan in tissues. Valsartan is largely bound to serum proteins (94-97%), mainly to serum albumin.

Valsartan does not undergo significant metabolism. About 20% of the administered dose is determined in plasma as metabolites. The hydroxyl metabolite is determined in plasma in low concentrations (less than 10% of the AUC of valsartan). This metabolite is pharmacologically inactive.

Valsartan is excreted in two phases: α-phase with T_1/2α less than 1 hour and β-phase with T_1/2β – about 9 hours. Valsartan is excreted mainly unchanged through the intestine (about 83%) and by the kidneys (about 13%). After IV administration, the plasma clearance of valsartan is about 2 L/h and its renal clearance is 0.62 L/h (about 30% of total clearance). The T_1/2 of valsartan is 6 hours.

On average, in patients with mild (5-6 points on the Child-Pugh scale) and moderate (7-9 points on the Child-Pugh scale) hepatic impairment, the bioavailability (by AUC value) of valsartan doubles compared to healthy volunteers of the corresponding age, sex and body weight.

Hydrochlorothiazide

After oral administration, C_max of hydrochlorothiazide is reached within 1-3 hours. Absolute bioavailability is estimated by cumulative renal excretion of hydrochlorothiazide and is about 60%. Binding to plasma proteins is 40-70%. V_d – 0.8±0.3 L/kg. It is not metabolized in the human body and is excreted in the urine almost unchanged. About 60% of the orally administered dose is excreted within 48 hours. Renal clearance is about 250-300 ml/min. T_1/2 – 10-15 hours. There is a difference in plasma concentrations between men and women. Women tend to have a clinically significant increase in plasma concentration of hydrochlorothiazide. In patients with impaired renal function, the excretion rate of hydrochlorothiazide is reduced. Studies involving patients with CC 90 ml/min have shown that T_1/2 of hydrochlorothiazide increases. In patients with reduced renal function, T_1/2 is about 34 hours.

Indications

• Grade II and III arterial hypertension.

Dosage Regimen

The drug is taken orally, regardless of meals, preferably in the morning, with a small amount of water.

For convenience, patients receiving therapy with amlodipine, valsartan and hydrochlorothiazide in separate tablets can be switched to therapy with this combination containing the same doses of active components, as well as if blood pressure control is insufficient on dual combination therapy (Valsartan+Hydrochlorothiazide, Amlodipine+Valsartan and Amlodipine+Hydrochlorothiazide) patients can be switched to triple combination treatment with the drug in appropriate doses.

In case a patient experiences dose-dependent adverse effects when using dual combination therapy with any components of the drug, to achieve a similar reduction in blood pressure, patients may be prescribed a drug containing a lower dose of the active component that caused this adverse effect.

The recommended daily doses of the drug are: 5 mg+160 mg+12.5 mg (1 tab. containing Amlodipine+Valsartan+Hydrochlorothiazide in doses of 5 mg+160 mg+12.5 mg); 10 mg+160 mg+12.5 mg (1 tab. containing Amlodipine+Valsartan+Hydrochlorothiazide in doses of 10 mg+160 mg+12.5 mg); 10 mg+320 mg+25 mg (2 tab. containing Amlodipine+Valsartan+Hydrochlorothiazide in doses of 5 mg+160 mg+12.5 mg).

The maximum antihypertensive effect of the drug is noted 2 weeks after dose increase. The maximum dose of the drug is 10 mg+320 mg+25 mg/day.

In patients over 65 years of age, dose adjustment of the drug is not required.

Since the safety and efficacy of the drug in children and adolescents under 18 years of age have not yet been established, the drug is not recommended for use in this category of patients.

In patients with mild and moderate renal impairment (CC >30 ml/min) and hepatic impairment (5-9 points on the Child-Pugh scale), dose adjustment of the drug is not required.

Adverse Reactions

Amlodipine+Valsartan+Hydrochlorothiazide

When using the drug, adverse events were mostly mild or moderate in severity. Discontinuation of treatment with the drug due to the development of adverse events was required in rare cases. Most often, the drug was discontinued due to the development of dizziness and pronounced decrease in blood pressure.

Use in Pregnancy and Lactation

It is known that the prescription of ACE inhibitors that affect the RAAS to pregnant women in the II and III trimesters leads to damage or death of the developing fetus. Given the mechanism of action of angiotensin II receptor antagonists, the risk to the fetus cannot be ruled out. According to a retrospective analysis, the use of ACE inhibitors in the first trimester of pregnancy was accompanied by the development of fetal and neonatal pathology. Hydrochlorothiazide crosses the placental barrier. When using thiazide diuretics, including Hydrochlorothiazide, during pregnancy, the development of embryonic or neonatal thrombocytopenia, as well as other adverse reactions observed in adult patients, is possible. With unintentional use of valsartan in pregnant women, cases of spontaneous abortions, oligohydramnios and impaired renal function in newborns have been described. Like any other drug that has a direct effect on the RAAS, it should not be prescribed during pregnancy and to women planning pregnancy.

Women of childbearing potential should be informed about the possible risk to the fetus associated with the use of drugs that affect the RAAS. If pregnancy is diagnosed during treatment with the drug, the drug should be discontinued as soon as possible.

It is not known whether Valsartan and/or Amlodipine pass into breast milk. In experimental studies, the excretion of valsartan in breast milk was noted. Hydrochlorothiazide is excreted in breast milk. The drug should not be used during breastfeeding.
