Use during pregnancy and lactation

Taking the drug Coaprovel® during pregnancy is contraindicated.

The use of ACE inhibitors in the II and III trimesters of pregnancy caused damage and death of the developing fetus. Therefore, during pregnancy, the use of irbesartan, as well as any other drug that acts directly on the RAAS is contraindicated.

Thiazide diuretics penetrate the placental barrier and are found in umbilical cord blood. Usually, the use of diuretics in pregnant women is not recommended due to the increased risk for the mother and fetus, including the development of fetal or neonatal jaundice, thrombocytopenia, and possibly other adverse reactions that are observed in adults. Especially not recommended to receive hydrochlorothiazide in the first trimester of pregnancy.

If the patient is planning a pregnancy or if during the treatment with the drug Coaprovel® established pregnancy, then taking the drug Coaprovel® should be terminated (in the event of pregnancy, as soon as possible). If it is necessary to continue antihypertensive therapy, the patient should be prescribed alternative antihypertensive therapy with drugs that have an established safety profile during pregnancy.

It is not known whether irbesartan is excreted in breast milk. Hydrochlorothiazide is excreted in breast milk.

Coaprovel® contraindicated for use during the entire period of breastfeeding due to the potential risk to the child. In addition, thiazides in high doses, causing intense diuresis, can suppress lactation. If necessary, take the drug Coaprovel® mother, breastfeeding should be discontinued.

Application for violations of the liver

Coaprovel® not recommended for patients with severe liver failure. In patients with impaired liver function, thiazides should be used with caution, but in patients with mild to moderate hepatic insufficiency does not require dose adjustment.

Application for violations of kidney function

Since the preparation contains hydrochlorothiazide, Coaprovel® not recommended for patients with severe impaired renal function (CC 30 ml / min).

No dose adjustment is required in patients with renal insufficiency with CC> 30 ml / min.

Use in children

Contraindication: age up to 18 years (efficacy and safety have not been established).

Use in elderly patients

Have elderly patients dose adjustment of the drug is not required.

special instructions

Coaprovel® occasionally causes excessive arterial hypotension in patients with elevated blood pressure without concomitant additional risk factors for its excessive reduction. Excessive reduction in blood pressure occurring with clinical symptoms, possibly in patients with reduced BCC or hyponatremia due to intensive diuretic therapy, a diet with limited salt, diarrhea or vomiting. Such conditions should be adjusted prior to the initiation of therapy with Coaprovel®. Thiazide diuretics can potentiate the action of other antihypertensive drugs.

Patients with stenosis of one or two renal arteries with the use of ACE inhibitors or angiotensin II receptor antagonists have an increased risk of marked reduction in blood pressure and the development of renal failure. Although when using the drug Coaprovel® until now, such side effects have not been observed, it is impossible to completely exclude the possibility of their development.

When using the drug Coaprovel® In patients with impaired renal function, periodic monitoring of the content of potassium, serum creatinine and uric acid is recommended. No experience with the drug in patients after kidney transplantation. Coaprovel® should not be used in patients with severe renal failure (CC = 30 ml / min).In patients with impaired renal function, thiazide diuretics may cause increased azotemia.

Special care is required when using vasodilators, including Co-Rapwell®, in patients with stenosis of the aortic orifice and mitral valve stenosis, with hypertrophic obstructive cardiomyopathy.

In patients with primary hyperaldosteronism, use of the drug Coaprovel® impractical because in these patients antihypertensive drugs that affect the RAAS are usually ineffective.

Thiazide diuretic therapy may decrease glucose tolerance. In patients with diabetes mellitus, it may be necessary to increase the doses of insulin or hypoglycemic drugs for oral administration. Thiazide Therapy
diuretics can cause the manifestation of latent diabetes.

Therapy with hydrochlorothiazide at a dose of 12.5 mg contained in some dosage forms of the drug Coaprovel®, practically does not affect the concentration of cholesterol and triglycerides.

In the treatment of thiazide diuretics in some patients, possible hyperuricemia or exacerbation of the course of gout.

Thiazides, including hydrochlorothiazide, can cause a disturbance of water and electrolyte balance (hypokalemia, hyponatremia, and hypochloraemic alkalosis). Thiazides have been shown to increase the excretion of magnesium ions by the kidneys, which can lead to hypomagnesemia. Although the use of thiazide diuretics may develop hypokalemia, simultaneous therapy with irbesartan may reduce the hypokalemia caused by the diuretic. The risk of hypokalemia increases in patients who simultaneously receive GCS or ACTH.

On the contrary, thanks to irbesartan, which is part of the drug Coaprovel®, hyperkalemia is possible, especially in the presence of renal failure and / or heart failure or diabetes. Regular monitoring of serum potassium in patients at risk is recommended. Potassium-sparing diuretics, potassium supplements or potassium-containing salt substitutes should be used with caution along with Coaprovel®.

There is no evidence that irbesartan can reduce or prevent hyponatremia caused by diuretics. Chloride deficiency is usually minor and does not require treatment. Thiazides can reduce the excretion of calcium by the kidneys and cause a slight increase in the calcium content in the blood serum, provided that there are no disturbances in calcium metabolism. Marked hypercalcemia may be a sign of latent hyperparathyroidism. Reception of thiazides should be stopped before the study of the function of the parathyroid glands.

Patients at risk of impaired water and electrolyte balance and metabolic disorders may require monitoring of laboratory parameters.

Hydrochlorothiazide can give a positive result during doping control.

The development of allergic reactions to hydrochlorothiazide is more likely in patients with aggravated allergic history or in patients with bronchial asthma.

When using thiazide diuretics, exacerbation of systemic lupus erythematosus was noted.

Sulfonamides, or derivatives of sulfonamide, can cause idiosyncrasy reactions, leading to the development of transient myopia and acute angle-closure glaucoma. Despite the fact that hydrochlorothiazide is a derivative of sulfonamide, so far only a few cases of acute angle-closure glaucoma have been reported without establishing a causal relationship with its administration. Symptoms of acute angle-closure glaucoma are: acute decrease in visual acuity or eye pain, usually occurring from a few hours to several weeks after starting the drug. Left untreated acute angle-closure glaucoma can lead to permanent loss of vision. If you experience these symptoms, you should stop taking the drug as soon as possible. If it is not possible to normalize intraocular pressure, then urgent therapeutic or surgical treatment may be required. Risk factors for the development of acute angle-closure glaucoma are
indications in the history of allergic reactions to sulfonamides and penicillins.

Joint use of the drug Coaprovel is not recommended.® with drugs containing aliskiren (double blockade of the RAAS), since there is an increased risk of an excessive decrease in blood pressure, the development of hyperkalemia and deterioration of renal function.

Use of the drug Coaprovel® in combination with drugs containing aliskiren, in patients with diabetes mellitus and renal failure, moderate and severe contraindicated.

Influence on ability to drive motor transport and control mechanisms

The influence of the drug Coaprovel® the ability to drive vehicles and mechanisms has not been studied, but on the basis of its pharmacodynamic properties it is unlikely that the drug affects this ability. While driving a vehicle or machinery, it is necessary to take into account that in rare cases dizziness and increased fatigue may occur during therapy of high blood pressure.


Symptoms: There is an experience of taking irbesartan in doses up to 900 mg / day for 8 weeks without the development of toxic effects. With an overdose of irbesartan, a pronounced decrease in blood pressure, tachycardia, bradycardia is most likely; with hydrochlorothiazide overdose, hypokalemia, hyponatremia, dehydration due to excessive diuresis. The most common signs and symptoms of overdose are nausea and drowsiness. Hypokalemia can lead to convulsions and / or increased arrhythmias in the case of concomitant use of cardiac glycosides (eg, digoxin) and antiarrhythmic drugs (eg, sotalol).

Treatment: there is no specific information about drug overdose®. In case of overdose, careful monitoring of the patient’s condition is required, therapy should be symptomatic and supportive. Treatment depends on the time elapsed from the moment of taking the drug, and on the severity of the symptoms.Recommended measures are provoking vomiting and / or gastric lavage, the use of Activated carbon , careful monitoring of the patient’s condition, and symptomatic and supportive therapy. Should regularly monitor the content of electrolytes and creatinine in the serum. In case of arterial hypotension, the patient should be laid on his back with raised lower limbs and as soon as possible to replace the salts and fluids.

Irbesartan is not displayed during hemodialysis.

Drug interaction

Antihypertensive effect of the drug Coaprovel® can be potentiated with the simultaneous use of other antihypertensive drugs, especially ganglioblockers, beta-blockers, diazoxide. Irbesartan and hydrochlorothiazide (at doses up to 300 mg of irbesartan / 25 mg of hydrochlorothiazide) have been safely used in combination with other antihypertensive drugs, including blockers of slow calcium channels and beta-blockers. High-dose diuretic therapy can lead to hypovolemia and an increased risk of excessive arterial hypotension.

Diuretics reduce the renal clearance of lithium and increase the risk of developing the toxic effects of lithium. In addition, the combination of lithium preparations with ACE inhibitors also showed an increase in plasma concentrations of lithium. So far, similar effects when taking Irbesartan were observed extremely rarely. In the case of taking the drug Coaprovel® The risk of a toxic effect of lithium may be increased. The use of a combination of the drug Coaprovel® with lithium preparations is not recommended. If this combination is still necessary, then the concentration of lithium in the plasma should be controlled.

Excretion of potassium when taking hydrochlorothiazide is reduced due to the potassium-sparing effect of irbesartan. However, this effect of hydrochlorothiazide can be enhanced by other drugs that cause potassium loss and hypokalemia (for example, diuretics, laxatives, amphotericin, carbenoxolone, penicillin G sodium salt, salicylic acid derivatives). On the contrary, based on the experience of using other medicines that reduce the activity of the RAAS, the concomitant use of potassium-saving diuretics, dietary supplements, salt substitutes containing potassium, or other medicines that can increase the content of potassium in the blood serum (eg, heparin), may lead to an increase in serum potassium. Hydrochlorothiazide used simultaneously with irbesartan can reduce the incidence of this effect. Patients at risk are recommended to conduct adequate monitoring of serum potassium.

Use of the drug Coaprovel® in combination with drugs containing aliskiren, is contraindicated in patients with diabetes mellitus or renal failure (moderate to severe form - GFR <60 ml / min / 1.73 m2) and is not recommended in other patients.

With the combined use of cardiac glycosides, antiarrhythmic drugs with the drug Coaprovel®in case of occurrence of hypokalemia and hypomagnesaemia caused by thiazide diuretic in its composition, the risk of arrhythmias increases, including and life threatening. The use of such combinations requires regular monitoring of the level of potassium in the serum.

With simultaneous use of the drug Coaprovel® and NSAIDs (including selective COX-2 inhibitors, acetylsalicylic acid> 3 g / day and non-selective NSAIDs) may weaken the antihypertensive effect of Co -provel® by reducing the effectiveness of hydrochlorothiazide and irbesartan.

As in the case of ACE inhibitors, the combined use of angiotensin II antagonists and NSAIDs can increase the risk of renal dysfunction, including the likelihood of acute renal failure, and lead to an increase in serum potassium in elderly patients and patients with reduced BCC, including receiving diuretics , in patients with impaired renal function. These effects are usually reversible. When using this combination, patients should not be dehydrated, treatment should be carried out under regular monitoring of indicators of renal function.

Based on in vitro research, Irbesartan is not expected to interact with substances metabolized by the isoenzymes CYP1A1, CYP1A2, CYP2A6, CYP2B6, CYP2E1 or CYP3A4. Irbesartan is mainly metabolized with the participation of the CYP2C9 isoenzyme and, to a lesser extent, by glucuronidation.

The pharmacokinetics of irbesartan when it is combined with hydrochlorothiazide and Nifedipine does not change.

No significant pharmacokinetic and pharmacodynamic interactions were observed with joint
the use of irbesartan with Warfarin , a drug that is metabolized by the isoenzyme CYP2C9.

The effects of CYP2C9 isoenzyme inducers, such as rifampicin, on the pharmacokinetics of irbesartan have not been evaluated.

When combined with irbesartan, the pharmacokinetics of Digoxin and Simvastatin did not change.

If ethanol, barbiturates or anesthetics are used with thiazide diuretics at the same time, orthostatic hypotension may be increased.

When using hydrochlorothiazide, you may need to increase the dose of hypoglycemic agents, because hydrochlorothiazide may increase blood glucose levels.

Hydrochlorothiazide absorption is reduced in the presence of anion exchange resins. It is necessary to divide by time the administration of these drugs (colestiramine or colestipol) for at least 4 hours.

With the simultaneous use of hydrochlorothiazide and GCS or ACTH perhaps a more pronounced electrolyte imbalance, in particular, increased hypokalemia.

May decrease the effectiveness of catecholamines (eg, norepinephrine) under the influence of hydrochlorothiazide.

The effects of non-depolarizing muscle relaxants, agents for local anesthesia, agents for general anesthesia and agents for sedation before general anesthesia can be potentiated by hydrochlorothiazide, and
