With regard to Eprosartan, two large-scale studies were carried out on patients with type 2 diabetes, as well as cardiovascular and cerebrovascular diseases. Based on the results of these studies, the following conclusions were made: the drug is recommended to be prescribed separately from ACE inhibitors and ARA II, as the risk of hyperkalemia, arterial hypertension, and acute kidney damage increases.

Of the contraindications to the use of Eprosartan, one can single out pregnancy, breastfeeding, serious disorders in the renal system, childhood, simultaneous administration together with the drugs that were mentioned above. Side effects: headache, problems with the functioning of the gastrointestinal tract, rhinitis, allergic skin reactions, renal failure in patients with disorders in the work of this system.

The drugs of this group have a number of characteristics that radically distinguish them from their predecessors. When choosing which drug from which company is better to buy, we recommend paying attention to this particular group - they have a minimum of side reactions, and they affect the human body in a complex (they suppress all angiotensin receptors at once).
Unfortunately, only one drug is officially registered in Russia - Telmisartan, all the rest are still outside the law. Therefore, before choosing a particular name on the Internet, it is worth finding out if it is accredited in our country.
Most often, this drug can be found in pharmacies under the Mikardis trademark. There are also names such as Telzap, Telmista, Telsartan, Pritor, Teseo, etc. In addition to the main active ingredient, the drug also contains the following components: sodium hydroxide, magnesium stearate, povidone K25, etc.
The main purpose is primary or secondary hypertension. The active ingredient blocks angiotensin II receptors, with an increase in dosage, it also regulates the level of sodium and chloride, and diuresis. It has the function of protecting the kidneys, reduces myocardial damage. The tool is able to control both types of blood pressure without affecting the heart rate.
Studies have shown that the substance is well absorbed through the gastrointestinal tract system, while it is excreted from the body slowly, for more than a day, most of it with feces (80%), the rest with urine.
Blood pressure begins to decrease 3 hours after taking the pill, the effect lasts for 3 hours or more, and becomes stable a month or two after the start of use. After the patient stops taking pills, the indicators smoothly return to their original values within a few days. There is no withdrawal syndrome. The effectiveness of the drug in young and old people does not differ. This medication is often prescribed to patients over 55 years of age who have cardiovascular disorders, which helps to reduce mortality, as well as hospitalizations associated with heart attacks and strokes.
Unlike most medicines, the list of contraindications is small - pregnancy, breastfeeding, hypersensitivity to any component of the drug, severe liver and kidney dysfunction. There are restrictions on the use of the drug by children, since large-scale studies of the effect on their body have not been conducted. It is also worth prescribing Telmisartan with caution to persons with obstructive cardiomyopathy, stenosis of heart valves, chronic heart failure, disorders in the functioning of the kidneys and liver in the initial stage, reduced volume of circulating blood, when belonging to the Negroid race.
Telmisartan must be drunk once a day, regardless of food intake. Depending on the disease, the initial dose is 20, 40, or 80 mg. It should be borne in mind that the required therapeutic effect is achieved 4-8 weeks after the start of administration, therefore, dose adjustment at the initial stages of use is not made. For patients with renal failure, the maximum dosage is 40 mg per day.
The most common side effects are weakness, increased fatigue, allergic manifestations in the form of skin rash and itching, excessive decrease in blood pressure, and infections of the genitourinary and respiratory system. There have been no confirmed cases of overdose. The following conditions are thought to occur: extreme drop in blood pressure, tachycardia, bradycardia, weakness, and dizziness. In case of an overdose, you should immediately seek help from a medical institution, provide peace and fresh air for the patient. If a short amount of time has passed after taking the medicine, it is recommended to induce vomiting and rinse the stomach, otherwise the use of specific medications is necessary.
