Edarbi®
Suction
Azilsartan medoxomil is a prodrug. After oral administration, it is converted to the pharmacologically active metabolite azilsartan during absorption from the gastrointestinal tract under the action of the enzyme carboxymethylenebutenolidase in the intestine and liver.
The estimated absolute bioavailability of azilsartan medoxomil when administered orally is approximately 60% based on plasma concentration profiles.
The maximum concentration (Cmax) of azilsartan in blood plasma is on average reached within 1.5-3 hours after taking the drug orally.
Food intake does not affect the bioavailability of azilsartan.
Distribution
The volume of distribution of azilsartan is about 16 liters. Azilsartan binds to blood plasma proteins (more than 99%), mainly to blood plasma albumin. The binding to plasma proteins remains constant when the concentration of azilsartan in the blood plasma significantly exceeds the range achieved when taking recommended doses.
There are no data on the use of the drug during pregnancy and breastfeeding. Azilsartan crosses the placenta of pregnant rats and is excreted into the milk of lactating rats (see section Use during pregnancy and breastfeeding).
Radiolabeled animal studies have shown that the amount of azilsartan that crosses the blood-brain barrier is minimal.
Metabolism
Azilsartan is metabolized to two primary metabolites primarily in the liver. The main metabolite in blood plasma is formed by O-dealkylation and is designated as metabolite M-II, the minor metabolite is formed by decarboxylation and is designated as metabolite M-I. The AUC (area under the concentration-time pharmacokinetic curve) values for these metabolites in humans are respectively 50% and less than 1% compared to azilsartan. M-I and M-II do not affect the pharmacological activity of Edarbi®. The main enzyme responsible for the metabolism of azilsartan is the CYP2C9 isoenzyme.
Removal
Azilsartan and its metabolites are excreted from the body, both through the intestines and the kidneys. Studies have shown that after oral administration of azilsartan medoxomil, about 55% (mainly in the form of metabolite M-I) is found in the feces and about 42% (15% in the form of azilsartan, 19% in the form of metabolite M-II) in urine .
The half-life of azilsartan is about 11 hours and the renal clearance is about 2.3 ml/min.
The equilibrium concentration of azilsartan is achieved within 5 days and its accumulation in the blood plasma does not occur with a single daily use.
Linearity/Nonlinearity
The pharmacokinetics of azilsartan in azilsartan medoxomil are dose proportional over a dose range of 20 mg to 320 mg following single or multiple oral doses.

No increase (+5%) in AUC was observed in patients with end-stage renal disease on hemodialysis. Clinical data on pharmacokinetics in patients with severe or end-stage renal failure are not available.
Azilsartan is not removed from the systemic circulation by hemodialysis.
Liver failure
Use of Edarbi® for more than 5 days in patients with mild (Child-Pugh class A) or moderate (Child-Pugh class B) severity of liver failure leads to a slight increase in AUC (1.3-1.6 times, respectively).
The pharmacokinetics of Edarbi® in patients with severe (class C on the Child-Pugh scale) degree of liver failure have not been studied.
Gender
The pharmacokinetics of azilsartan in men and women is not significantly different. No dose adjustment is required depending on gender.
Race
The pharmacokinetics of azilsartan do not differ significantly depending on the race of patients. No dose adjustment is required based on race.
Instructions for use Edarbi Clo tablets 40 mg + 12.5 mg 98 pcs
Edarbi® Clo is a combination drug that contains an angiotensin II receptor antagonist (azilsartan medoxomil) and a thiazide-like diuretic (chlorthalidone). The simultaneous use of two active substances leads to a more pronounced decrease in blood pressure (BP) compared to taking each of them in monotherapy. When taking the drug once a day, an effective reduction in blood pressure is achieved within 24 hours. Azilsartan medoxomil , one of the active ingredients of the drug Edarbi® Clo, is a specific antagonist of angiotensin II type 1 receptors (AT1). Angiotensin II is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II). Angiotensin II is the main vasoconstrictor factor of the RAAS (renin-angiotensin-aldosterone system), its actions include vasoconstriction, stimulation of aldosterone synthesis and secretion, increased heart rate (HR) and renal sodium reabsorption. Azilsartan medoxomil is an oral prodrug. Azilsartan medoxomil is rapidly converted to the active molecule azilsartan, which selectively antagonizes the effects of angiotensin II by blocking its binding to AT1 receptors in various tissues, such as vascular smooth muscle and the adrenal gland. Therefore, its action is not related to the angiotensin II biosynthetic pathway. The AT2 receptor is also found in many tissues, but it is not involved in the regulation of the cardiovascular system. The affinity of azilsartan for the AT1 receptor is 10,000 times higher than for the AT2 receptor. Inhibition of RAAS activity through ACE inhibitors, which suppress the formation of angiotensin II from angiotensin I, is widely used in the treatment of arterial hypertension. ACE inhibitors also suppress the breakdown of bradykinin, which is catalyzed by ACE. Since azilsartan does not inhibit ACE (kininase II), it should not affect bradykinin activity. Azilsartan does not bind to or block other receptors or ion channels that play an important role in the regulation of the cardiovascular system. Azilsartan dose-dependently suppresses the vasoconstrictor effects of angiotensin II infusion. A single dose of azilsartan at a dose equivalent to 32 mg of azilsartan medoxomil suppressed the maximum vasoconstrictor effect of angiotensin II by approximately 90% at the time of highest concentration, and by approximately 60% 24 hours after administration. In healthy volunteers, plasma concentrations of angiotensin I and angiotensin II and renin activity increased, and aldosterone concentrations decreased after a single oral dose and after repeated doses of azilsartan medoxomil; No clinically significant effect on serum potassium or sodium levels was detected. In general, the pharmacodynamic properties of azilsartan medoxomil are consistent with blocking the AT1 receptor. The antihypertensive effect of azilsartan medoxomil develops during the first 2 weeks of use with the maximum therapeutic effect achieved after 4 weeks. A reduction in blood pressure after oral administration of a single dose is usually achieved within a few hours and persists for 24 hours. Chlorthalidone , a thiazide-like diuretic, inhibits the active reabsorption of sodium ions in the renal tubules (the initial part of the distal convoluted tubule of the nephron), increasing the excretion of sodium and chloride ions and increasing diuresis. In addition, chlorthalidone increases the excretion of potassium, magnesium and bicarbonate ions, and retains calcium ions and uric acid. The antihypertensive effect of chlorthalidone is associated with the removal of fluid and sodium from the body. The diuretic effect develops 2-3 hours after taking chlorthalidone orally and persists for 2-3 days. The antihypertensive effect of chlorthalidone develops gradually with the maximum therapeutic effect achieved 2-4 weeks after the start of therapy. In clinical trials, the combination of azilsartan medoxomil/chlorthalidone was more effective than the combination of azilsartan medoxomil with hydrochlorothiazide or the combination of olmesartan medoxomil/hydrochlorothiazide, although a higher proportion of study participants in the comparison group required a dose increase due to insufficient blood pressure (BP) control. In a double-blind, 12-week dose-escalation study, azilsartan medoxomil/chlorthalidone 40 mg/25 mg was statistically significantly superior to olmesartan medoxomil/hydrochlorothiazide 40 mg/25 mg in reducing systolic blood pressure in moderate to severe hypertension. Similar results were obtained in all patient subgroups, regardless of age, gender or race. The combination of azilsartan medoxomil/chlorthalidone lowered blood pressure more effectively than the combination of olmesartan medoxomil/hydrochlorothiazide in each hour of the 24-hour interval between doses of drugs, according to ABPM (24-hour blood pressure monitoring).
When can you drink alcohol if you are taking or have taken the drug?
During treatment with the drug for hypertension, diseases associated with increased blood pressure, the duration of which is on average 4 weeks, you should not drink any alcoholic beverages.
After completing therapy, at least 2 weeks must pass before you can drink alcohol. The medication, as well as ethanol, is prohibited for women during pregnancy at any stage.
After a single dose of tablets, the therapeutic effect is achieved within a few hours and lasts for 24 hours. To avoid unpleasant consequences, after taking the pill, at least 24 hours should pass before drinking alcohol (for men). Women need to wait even longer - 32 hours.
This blood pressure reducer and ethanol do not mix. Taken together, without taking into account the rules of use, they can cause increased side effects in the human body; the load on the liver and kidneys can significantly increase, especially if they are affected by the disease. An already unimportant condition may worsen due to a hangover.
Compatibility of Edarbi and alcohol
? The effect of alcohol on blood pressure is not the same and depends on the volume drunk - in small quantities it dilates the arteries and the pressure drops, but when ethanol enters the body in large volumes it increases. Despite the fact that the drug is intended to combat hypertension, it should not be taken together with alcohol.
Almost all types of alcoholic beverages, weak and strong, can affect the medication: wine, beer, vodka, other strong drinks with a high alcohol content, champagne, etc.
To do this, it is enough to drink very little: 350-250 ml of beer, 100-150 ml of wine, 50 ml of vodka. This amount of alcohol is calculated for a person with an average weight of 60 kg.
Edarby and beer
It is forbidden to take Edarbi with beer, because pressure surges caused by this tandem significantly worsen the condition of the sick patient.
By mixing two substances, the toxic load on the liver, and subsequently on the kidneys, greatly increases. The fact is that the filtering organ’s priority is purification from ethanol, as a result of which the drug gradually accumulates in the tissues, causing an overdose or intoxication.
As a result, the heart rhythm may be disturbed, tachycardia, bradycardia, symptoms of acute heart failure appear, and the risk of stroke and heart attack increases.

Using the drug for a hangover
Side effects include:
- dizziness;
- nausea;
- diarrhea;
- muscle spasms;
- vomit;
- the occurrence of angioedema;
- severe fatigue;
- excessive decrease in blood pressure, hypotension.
Drinking alcohol causes the same consequences, that is, if you take pills during a hangover, the unpleasant symptoms may intensify. To avoid deterioration of the general condition, it is recommended to refrain from taking the drug until the body returns to normal or reduce its dose.
Consequences of drinking alcohol
When taking the drug together with ethanol, there is a noticeable increase in the load on the liver and kidneys - organs that are busy processing and then removing the intoxicating substance from the body.
There is a load on the heart - the heart rhythm may be disturbed, tachycardia, bradycardia may develop, symptoms of acute heart failure may appear, and there is a risk of stroke and heart attack.
For this reason, you should not drink alcohol and medication together, the compatibility of which will affect internal organs.
If symptoms of disturbances are detected, you need to stop drinking alcohol and drink more fluid for at least 4 hours to restore its balance in the body. This will help improve the condition. If there is no improvement, it is recommended to consult a doctor.
Use of the drug for alcoholism
Constant drinking of alcohol creates the preconditions for the development of hypertension, as alcohol increases blood pressure. If you drink alcoholic beverages regularly, almost every day, as happens with alcoholism, then your blood pressure will almost always be elevated because it will not have time to decrease to normal levels.
Ethanol increases blood pressure if it was elevated before taking it, as well as if it was normal.
It has been established that ethanol reduces the effectiveness of medications aimed at treating hypertension, therefore, if you simultaneously take the drug while regularly drinking alcohol, you should not expect an immediate antihypertensive drug effect from the drug.
In alcoholism, internal organs suffer from the destructive effects of ethanol, primarily the liver and kidneys. In case of severe disorders of these organs (which is often observed in people suffering from alcoholism), as written in the instructions for the medication, taking the medication is prohibited.
