Vision problems significantly impair the quality of life. This makes people in every possible way look for means to solve these troubles. Today, medicine has made a significant leap, and many eye diseases are treated by surgery in just a few minutes. However, even with such apparent simplicity, preparation for an operation involves several steps. And the most important of these is a diagnostic examination. And it is impossible without certain drugs that allow the specialist to carry out a series of manipulations with the eyeball.
Most often, ophthalmologists use Irifrin eye drops as such a means. They are widely used in the treatment of eye diseases, as well as to lower intraocular pressure. In the article we will carefully consider the eye drops "Irifrin": reviews, price, analogues and instructions for use. In addition, we will talk about the rules of using the drug for children. In such cases, the treatment regimen for eye drops "Irifrin" depends on the disease that is recorded on the outpatient card of a small patient.
General information about the drug
Briefly, the Irifrin eye drops (we will talk about analogues and patient reviews a little later) cause vasoconstriction in the eyeball. A similar effect is simply necessary when conducting various kinds of diagnostic tests and preparing for surgery. For a number of pathologies of the vascular system of the eye, ophthalmologists prescribe a course of treatment with Irifrin eye drops. It is noteworthy that they are prescribed for children. This significantly expands the possibilities of using this drug.
The instructions for eye drops "Irifrin" (analogues are usually not indicated in it) mention that the tool can only be used topically. The main effect of the drug is expressed in a decrease in intraocular pressure due to narrowing of blood vessels and dilated pupil. In addition to these effects, drops significantly and quickly remove eye swelling. In certain diseases, the drug is prescribed in order to regulate the outflow of intraocular fluid.
Irifrin eye drops were developed in India. Until now, the drug enters the Russian drug market from this country. The manufacturer of the drug is the company "Centiss Pharma". Sometimes in pharmacies drops may be found produced by the Russian pharmaceutical company ProMed.
In the instructions for eye drops "Irifrin" prices and analogues of the funds are never indicated. However, many patients are very concerned about the cost of their prescribed medication and the ability to replace it with a similar, but cheaper, if necessary. On average, the price of Irifrin eye drops (we will talk about analogues in one of the following sections of the article) ranges from five hundred to six hundred rubles. The cost of packaging depends on the manufacturer. Therefore, in large cities there is a high probability of finding a drug at a low price. In St. Petersburg, Irifrin eye drops, for example, can be found for four hundred rubles. Experts note that the price does not affect the quality of the product.
The composition of the drug
Before starting treatment, it is necessary to study the instructions for eye drops "Irifrin" (we already talked about the price of the drug above). Since it is very important to understand due to which substance the necessary effect of the drug arises.
Naturally, drops have in their composition an active component and a number of excipients. The main component is the substance phenylephrine. It is upon contact with the eyeball that acts on the capillaries and constricts the vessels. It is important to understand that the drug equally effectively affects small and large vessels. As a result, the patient's pupil narrows.
This phenomenon occurs some time after application. Typically, the therapeutic effect becomes noticeable in the interval from thirty to sixty minutes. In this case, the components of the drug are not absorbed into the bloodstream and are quite easily excreted from the body.
Additional substances in the composition of the drug are indicated in its instructions. Eye drops "Irifrin" (the price makes the drug quite affordable for most patients) contains the following components:
- water for injections;
- lemon acid;
- sodium hydroxide;
- benzalkonium chloride.
The color of the drops is usually light yellow, in some bottles they are completely transparent. Both options are the norm.
Release form and dosage
The instructions for eye drops "Irifrin" (a lot of information can be found on the price and analogues in patient reviews) indicates that the drug exists only in the form of drops. However, their dosage may be different.
Most often, ophthalmologists prescribe eye drops in a dosage of 2.5% to their patients. In such a preparation, in one milliliter of liquid contains twenty-five milligrams of the active substance.
In addition, in pharmacies there is a 10% drop (Irifrin BK). In them, per milliliter of medicine - one hundred milligrams of phenylephrine. This form is usually used by specialists in medical institutions. It is noteworthy that such drops contain more auxiliary components in the composition than another form of release.
Usually in the package is one bottle of dark glass or plastic. Each contains five milliliters of the drug. If the package contains a glass bottle, then a dropper should go to it. The plastic form of the package has already been originally made in such a way as to dispense the product.
Pharmacology
In each instruction for eye drops "Irifrin" its pharmacokinetics and pharmacodynamics are described in detail. We will talk about them in this section of the article.
When applied topically, the drug penetrates very easily and quickly into the tissues of the eye. It reaches its maximum concentration in plasma after ten to twenty minutes. If before its use the doctor used anesthetics, then the effect of the expansion of the pupil will last a little longer than usual. The drug is excreted with urine.
The drug has a very high activity, but does not have any significant effect on the central nervous system of the patient, subject to the dosage specified in the instructions.
Irifrin eye drops may slightly affect the cardiovascular system. This effect must be taken into account by doctors when prescribing a drug to patients.
When instilling the drug with a concentration of 2.5% for two hours, the pupil will be in an expanded state. When using a 10% solution, the effect will last much longer - from three to six hours.
Options for the use of "Irifrina" with other drugs
In the instructions for eye drops "Irifrin BK" (the price of a medicine, by the way, varies not only depending on the manufacturer, but also on the dosage), an item on interaction with other drugs is highlighted.
First of all, you can not use drops in parallel with atropine. Both substances in the interaction several times reinforce each other. As a result, the patient begins to experience rare attacks of tachycardia. With further treatment, they can become regular and cause heart disease.
The possibility of using drops with beta-blockers raises many questions. Doctors often refuse to combine such drugs. However, it is possible, but it is important to consider the pressure of the patient. If he suffers from arterial hypertension, then Irifrin cannot be combined with treatment with beta-blockers.
The vasoconstrictor effect of the drug can be enhanced by various drugs. Every patient who is prescribed Irifrin eye drops should know about them. In the instructions for use, these funds are not listed, but we will definitely give them in the article. This group includes antidepressants (tricyclics) and propranolol. Guanethidine and reserpine can also be included here.
Indications for use
The use of Irifrin eye drops is indicated for various vision problems. The drug is prescribed before surgery on the eye. In this case, medical intervention can be surgical and laser. In any case, the patient should use Irifrin.
Often starting vision problems are very difficult to diagnose. Especially when it comes to a disease such as angle-closure glaucoma. If it is suspected, the ophthalmologist prescribes a series of tests that are impossible to do without eye drops.
Also, the drug is prescribed for patients complaining of constant redness of the eyes. If the diagnosis did not reveal any serious diseases, then usually the course of treatment with "Irifrin" removes this problem.
Diagnosis of blood vessels of the organs of vision is impossible to carry out without the drug described by us. It is included in the preparation for the examination and in the adaptation period after it.
Inflammations of the iris and cornea of the eye are rather unpleasant diseases that can take a chronic form and provoke a number of other vision problems. Therefore, inflammation must be neutralized at the initial stage. Eye drops "Irifrin" do a good job of this (reviews about the analogues of this product do not contain such information).
The drug is also indicated for glaucomyclic crises. It is especially important to start using drops if the problem is accompanied by an increase in intraocular pressure.
A medication is also prescribed in cases of occurrence of accommodation spasms. In this situation, drops must be used according to a special scheme.
Contraindications
The drug has a number of contraindications, however, compared with other similar means, it is not too wide. It is strictly forbidden to conduct treatment or diagnostic procedures with the help of "Irifrin" for people with glaucoma of any degree and impaired eye integrity.
In some patients, intolerance to the components of the drug occurs. In this case, the risks of developing an allergic reaction are high, which can provoke serious vision problems in the future.
You should not use these eye drops with increased thyroid activity and various diseases of the cardiovascular system. If this recommendation is not followed, the patient may first feel a general deterioration in well-being, and then, for example, tachycardia and other problems with the heart muscle.
If a patient has cerebrovascular accidents, then treatment with Irifrin is also contraindicated.
Instructions for use
The treatment regimen for the drug depends on the disease that is diagnosed in the patient and the medical procedures shown to him.
For vision problems, doctors often prescribe an examination such as ophthalmoscopy. For its implementation, it is necessary that the pupil is in an expanded state. This is achieved by digging drops of "Irifrin" into the eye. Usually, a 2.5% solution of the drug is used for such purposes, but in rare cases, a 10% solution is used. To dilate the pupil, one drop of medicine is enough. The desired effect is achieved in about half an hour. It lasts from one to three hours. If you plan to diagnose longer, then the instillation must be repeated after one hour.
Inflammation of the iris is treated with a 2.5% or 10% solution of the drug. Usually, the doctor prescribes one drop in each eye three times a day. The duration of treatment is determined by the ophthalmologist, but in most cases it does not exceed a week.
You can relieve the spasm of accommodation in about four weeks. Throughout this time, the patient should drip one drop of the drug overnight. Most often, a 2.5% solution of the drug is prescribed. If the expected effect does not occur, then an ophthalmologist may recommend a drug with a different dosage.
As a preparation for surgical intervention, "Irifrin" is used once. It is instilled approximately one hour before the procedure. During the operation, the use of this medication is impossible, since the integrity of the shell of the eye is violated.
Glaucomocyclic crisis requires treatment with a 10% solution of the drug. It must be instilled one drop three times a day. The course of treatment is calculated individually and ends when all symptoms of the disease are eliminated.
When conducting various tests, eye drops are used in different ways. For example, in cases of suspected angle-closure glaucoma, intraocular pressure is measured before and after instillation of "Irifrin." If the difference in indicators reaches five millimeters of mercury, then the disease can be considered confirmed.
The use of eye drops "Irifrin" children
Ophthalmologists in certain situations prescribe the drug to their small patients. However, parents should consider that for children, Irifrin eye drops can only be used when they are six years old. Younger children require the selection of other medicines.
If you refer to the instructions for use and parental reviews, for children, Irifrin eye drops can be used only at a dosage of 2.5%. This concentration is suitable in the treatment of accommodation spasm, ophthalmoscopy and other manipulations.
At a dosage of 10%, Irifrin eye drops for children (in parental reviews these data are often mentioned) are used only after reaching the age of twelve. Subject to all medical recommendations, the drug will be safe for the child and will relieve all unpleasant symptoms. Usually, the course of treatment for children does not exceed seven days. In rare cases, it can drag on for fourteen days.
Analogs of eye drops "Irifrin"
This drug has a lot of similar drugs. They can be prescribed if any contraindications to the original drops are detected. The most popular analogues of Irifrin eye drops are listed in the following list:
- Mesaton. This drug is prescribed for the treatment of inflammation of the cornea and for diagnostic procedures.
- Cyclomed. When the drug enters the eyeball, the muscles relax, which are responsible for changing the size of the pupil. As a result, it expands. Doctors say that Cyclomed is very quickly absorbed into the mucous membrane and then removed from the body as soon as possible. It is proved that a small amount of the drug enters the circulatory system.
- Midriacil. This drug has virtually no side effects. It is well tolerated by all age groups of patients. He is often assigned to children under the age of six. In addition to the direct expansion of the pupil, necessary during examinations, the medicine is prescribed for various eye diseases. For example, it is very effective for false myopia.
- Visofrin. Its action is as close as possible to "Irifrin." Therefore, the spectrum of its use is almost identical to the eye drops we describe.
The price category of all of these analogues in most Russian cities does not exceed six hundred rubles.
Drug Reviews
Many patients, before starting treatment with Irifrin, carefully study the reviews posted on the Internet. They are quite numerous and give a complete picture of how the drug affects the body.
Even a cursory glance at the comments makes it clear that the medicine is very well tolerated. Therefore, it is often dripped even with tired eyes. Many patients write that after a day at work at the computer they experience unpleasant sensations. After applying Irifrin, they disappear, and the eyes become rested.
Despite the fact that in most reviews the drug is considered effective, some patients write that it caused them discomfort. They note that after instillation, the eyes turn red and the burning sensation persists for a long time. Therefore, children are usually naughty when treated with Irifrin.
Often in reviews it is written that after two weeks of treatment, improvements become noticeable. Those who had previously seen only the eighth line at the ophthalmologist’s appointment began to see the sixth. At the same time, vision continued to recover after the end of treatment. In such cases, "Irifrin" is prescribed for the prevention of relapse once every six months.
