Captopril tablets against pressure - instructions for use, analogues

Tablets Captopril from pressure is one of those versatile products that are useful to have in a home medicine chest. This drug can be taken on a regular basis to maintain the blood pressure in a normal way, and it is possible( most often, to do so) for an emergency reduction in blood pressure. Captopril is a strong medication that is sold in pharmacies according to a prescription. It should be taken only as prescribed by the doctor, since the dosage of the drug varies greatly, and improper administration can seriously harm your health.

Captopril from pressure - description of the drug

Captopril belongs to antihypertensive( i.e., pressure-reducing), drugs from the group of ACE inhibitors. It is available in tablets intended for oral administration. In emergency cases, when it is necessary to urgently reduce blood pressure, it is possible to apply the drug sublingually( under the tongue).With resorption under the tongue, active substances very quickly penetrate into the bloodstream and after 15 minutes have the necessary action. This allows the use of captopril for relief of hypertensive crisis and prevention of dangerous complications.

When ingested, the drug is quickly absorbed into the stomach, the effect of its use occurs within an hour. But it should be borne in mind that the simultaneous intake with food slows the absorption of the drug and lengthens the time necessary for the onset of therapeutic action. Captopril is processed by the liver and is excreted from the body with feces. There is reliable information that Captopril is excreted in the mother's milk, which can cause a sharp drop in blood pressure in the baby, so during cessation, it is absolutely contraindicated.

Principle of operation of

The mechanism of action of captopril is based on the fact that it interferes with the operation of one of the main systems that raise blood pressure. RAAS( renin-angiotensin-aldosterone system) is a chain of consecutive substances that stimulate the production of each of the following substances in the chain. The final substance is aldosterone, narrows vessels and raises the level of renal blood flow. Due to this, blood pressure rises.

Captopril blocks the work of one of the enzymes of this system - angiotensin converting( ACE).As a result, the hypertensive effect of RAAS becomes less pronounced, the vessels dilate and blood pressure decreases. The effect on the ACE is due to the fact that only this component of the system is completely contained in the blood, so it is easier to influence it than the rest.

Composition of the drug

The active substance of the drug is captopril, one of the first synthesized ACE inhibitors. In addition, each tablet contains additional substances that are necessary for the convenience of the drug. These include lactose, dry starch, castor oil and ingredients.

Captopril is released only in the form of tablets, with different contents of active substance - 12.5 mg, 25 mg and 50 mg. Tablets of 10 pieces are packaged in contour squares and cardboard packs. The pack can contain 2 or 4 packs of tablets.

Indications

Captopril is used to lower blood pressure when:

• arterial hypertension( including renova-vascular);
• in the complex treatment of chronic heart failure.

The main indication for emergency use of Captopril is hypertensive crisis, that is, a sharp increase in blood pressure( over 160/100).This condition is accompanied by weakness, severe headache, visual impairment until its temporary loss, impaired consciousness, fainting. The hypertensive crisis requires immediate medical attention, so the patient must be taken to a hospital or called an ambulance.

Hypertensive crisis can develop with essential and renal hypertension, especially malignant( resistant to other drugs) flow. Captopril in such cases causes a rapid decrease in blood pressure and allows you to stop the crisis.

In small doses for daily use, it is prescribed in patients with heart failure after myocardial infarction, as well as for the treatment of nephropathy in patients with diabetes mellitus. The dosage of the drug in this case is selected individually, since there is a risk of excess pressure reduction.

Contraindications

Consultation of the doctor

Instructions for use Captopril does not recommend the use of it for various vessel stenoses, especially the aorta and renal artery, with stenosis of the heart valves, myocardiopathy, edema of any origin, primary hyperaldosteronism, and during pregnancy and breastfeeding. The drug is contraindicated in children and adolescents, it can not be prescribed with a tendency to allergic reactions and individual sensitivity to the components. In addition, the following conditions refer to the list of contraindications:

• renal dysfunction( hyperkalemia, conditions after kidney transplantation);
• liver disease;
• decreased blood pressure( hypotension);
• cardiogenic shock.

With special care and under the supervision of a specialist, the drug is prescribed for severe autoimmune diseases, cerebral ischemia, diabetes mellitus, coronary heart disease. To this list, you can add patients with cerebral circulation depression, patients on hemodialysis, as well as patients who observe a certain diet that limits sodium intake.

Instructions for use

Drug Captopril is taken by mouth, the dosage, frequency and frequency of application depend on the purpose for which it is intended. There are several basic schemes of admission:

1. for relief of hypertensive crisis;
2. for the treatment of heart failure;
3. for the control of chronic arterial hypertension.

The effectiveness of the drug is significantly increased if taken on an empty stomach. The effect after admission occurs within 40-60 minutes.

For the treatment of chronic arterial hypertension, the drug is prescribed first in a minimum dose of 1/4 tablets( 12.5 mg) twice a day. If the effectiveness of such a method is not sufficient, then firstly increase the frequency of reception - from two to three times a day, then gradually increase the dosage of the drug. The maximum dose is 1 tablet( 50 mg) three times a day. When side effects occur, the dose is reduced.

For hypertensive crisis

For hypertensive crisis, appoint Captopril under the tongue, one tablet every 20 minutes. The maximum dose is 3 tablets. This allows you to quickly reduce blood pressure and ease the patient's condition. When pains in the heart, along with Captopril, nitroglycerin can be used, but in this case the dosage of the drug is reduced to two tablets to avoid an excessive drop in pressure.

For the treatment of myocardial infarction in the first three days, appoint Captopril in a dosage of 3 tablets three times a day, then reduce the dose. In the acute period of infarction, the patient is not allowed to walk and exercise physical activity, since the heart muscle has not yet adapted to the load, and taking the drug can lead to complications.

At what pressure to take

At what pressure to take Captopril, depends not only on the indications of the tonometer, but also on the characteristics of the course of the disease. In some cases, the prescription of this drug is possible even at a systolic blood pressure of 140 mm.gt;If the patient experiences symptoms of a hypertensive crisis.

In pregnancy, taking the drug is stopped and replaced by Captopril for other, safer drugs. If a pregnant woman has a hypertensive crisis or a myocardial infarction, the question of termination of pregnancy may be raised.

How to take captopril during breastfeeding, the situation is similar. The drug is contraindicated during lactation, but if its avoidance can not be avoided, then breastfeeding should be stopped and the baby transferred to artificial mixtures, since Captopril is excreted in breast milk and can cause severe hemodynamic disorders in the baby. Children and adolescents under 18 years of age are not prescribed this medication.

Side effects of

The drug has an extensive list of side effects that occur throughout the time that Captopril acts. Improper intake of the drug can significantly exacerbate their manifestation. The most frequent manifestations arise from the cardiovascular system. This is primarily orthostatic hypotension - a sharp drop in pressure when trying to stand or sit down, a feeling of heartbeat, possibly a violation of the heart rate.

Of the other side effects of captopril, patients note the appearance of weakness, drowsiness, neurasthenic syndrome, decreased mental and physical performance. Often when taking the drug there are violations of blood clotting, changes in laboratory indicators of blood and urine. It is especially important for diabetics to consider that Captopril can cause acidosis, to which patients with diabetes are predisposed, so during treatment it is necessary to limit the use of acidic foods.

On the part of the digestive system, there may be nausea, lack of appetite, stools, dry mouth, changes in taste. In addition, Captopril from pressure can provoke allergic and immunological reactions, among which serum sickness, Quincke's edema, lymphadenopathy.

In case of an overdose of Captopril, there is a sharp decrease in blood pressure, possible thromboembolic complications. In this case, it is recommended to give the patient a horizontal position. Symptoms of overdose are able to pass independently for several hours, but a much better result gives hemodialysis.

Analogues of Captopril

Analogues of the drug for the active substance - Kapoten, Kaptopres, Alcodil. These medicines contain the same active substance - captopril. Other drugs with a similar hypotensive effect may be representatives of different groups:

• Beta-blockers;
• Calcium channel blockers;
• Nitrates.

All these drugs have their own application and their indications. Therefore, unequivocally answer the question, which is better than Captopril, it is impossible. Typically, the drugs are selected by the doctor individually, taking into account many parameters: the patient's condition, age, contraindications and the presence of concomitant diseases.

Review No. 1

Captopril from pressure was discovered by chance. Prior to that, they always bought Kapoten, but once again, when the pressure increased, and he was not found in the medicine cabinet, he went to the nearest pharmacy.

There I was offered a similar remedy with the same active substance, but almost 10 times cheaper. I had to take, because I did not see any other options. After 40 minutes after receiving one tablet, I felt an improvement. Has measured pressure - in norm.

Now instead of an expensive drug with the same effect and composition, we get Captopril. It is transferred easily, no side effects were present.

I generally hypotonic and low blood pressure for me - this is the norm. Usually I do not suffer from high blood pressure, but once a sharp jump in pressure brought me to an unconscious state. I had to call an ambulance, and the doctor on duty just gave me a little pills.

After a while, I already felt much better. So I learned about Captopril, and now he is always with me. I drink it very rarely when such attacks occur, but I try not to do it often, because it has an impressive list of side effects. From other pluses I can note that the cost of the drug is slightly more than 20 rubles.

Review No.3

In our family until recently, problems with increased pressure were only for my mother. But it turned out that her husband had similar problems, but he never complained about his health. If you suddenly have a headache, you just drank anesthetic and continued to do your own thing.

However, about six months ago he felt very bad: the headache was so severe that he had to call an ambulance. The doctor recorded high blood pressure, injected something, and the husband fell asleep. After that, we went to the polyclinic, and he was diagnosed with hypertension.

The doctor prescribed a bunch of medications, among which was Captopril From pressure. As it turned out, my mother also was treated with this remedy. He says it helps very well and quickly reduces blood pressure.

Now my husband also takes Captopril and it is much easier for him. Even with a sharp change in the weather, the pressure does not jump much, although earlier in such periods he was sick.

Review No.4

Now even young people may have problems with pressure. I'm 27 years old, but I periodically suffer from such attacks. Especially strongly the body reacts to changing weather conditions. I discovered a cheap and very effective tool - Captopril.

Only for 20 rubles you can buy a package, in which 40 tablets. Constantly and even as a prophylaxis I do not accept, only when the pressure rises. It helps quickly: about 20 minutes after taking it, I already feel much better.

No side effects found during this time, it is easily transferred. The only time when this tool did not help me, the pressure jumped to 180. Then I had to call an ambulance. In general, Captopril always helps me out.
