The human eye has an interesting and complex structure. The operation of the visual apparatus directly depends on how carefully a person monitors his health. If you do not turn to a specialist in time, postpone the visit to the doctor "in the long box" in case of discomfort, you can seriously damage the visual system.
In the era of progress, when almost every workplace has a computer, and at home in all rooms there are TVs, eyes are subjected to a huge load. Constant tension and continuous contact with a bright screen leads to drying out of the mucous membrane of the eye. The main symptom of a violation of the secretion of the lacrimal glands is a burning sensation, a feeling of sand under the eyelids.
To avoid dire consequences, ophthalmologists advise the use of tear fluid substitutes . They include the gel "Vidisik."
High molecular weight polyacrylate in ophthalmology
Along with drugs that relieve inflammatory processes, doctors began to prescribe the drug "Vidisik". Instructions for use of the gel indicate that this dosage form is used to protect the mucous membranes of the eye, as replacement therapy.
Due to its interesting composition, the Vidisik gel interacts with mucins of the mucous glands of the eye, forming a thin film that protects the sclera from external irritants.
Carbomer or carbopol, is the main active ingredient, as well as a derivative of acrylic acid. To obtain a gel-like mass, the polymer is specially prepared in pharmaceutical factories. The resulting paste is used for the preparation of drugs on a soft basis.
What is it for?
The main specificity of all drugs used in ophthalmic practice is considered to be in full compliance with the physiological characteristics of the mucosa. The film obtained during application becomes an excellent tool for people suffering from dry eye syndrome, mucosal irritation and inflammatory conjunctival diseases.
In addition, "Vidisik" gel is an aid in case of violations of the production of tear fluid, to restore the mucosa after injuries.
Method of use
The interaction period of the carbomer and the cornea is one and a half hours. It can be used up to five times a day, or even more, one or two drops in each eye. Before going to bed, it is advisable to carry out the procedure half an hour before bedtime.
But do not forget that the duration of treatment depends on the problem, and the gel is prescribed by the attending ophthalmologist.
Overdose and side effects
There was no information about an overdose of this drug, since the active substance in the gel is in small quantities.
But there is a likelihood of a temporary worsening of symptoms: burning, pain. This is due to the presence of a preservative, which, with prolonged use, can give a similar result in the form of irritation, damage to epithelial cells on the mucous membrane of the eye.
The manufacturer advises people who constantly use moisturizing preparations to change it to a dosage form without preservatives.
Interaction
As you know, any barrier agent affects the ability to be absorbed in other substances. Vidisik is no exception. Given its ability to retain moisture, it can prolong the action of drugs used in the treatment of "eye" diseases.
Therefore, the interval in the administration of various drops along with the Vidisik gel in the instructions for use is indicated for at least five minutes. Ideally, fifteen. Highlights : The gel is applied last.
Pregnant, lactating and children
Expectant mothers can apply Vidisik gel. The instructions for use say that its use is possible if the expected benefit outweighs the risk to the fetus. Although the composition of the drug includes substances that almost do not affect the functioning of internal organs and systems.
Clinical studies in this category of the population have not been conducted, but taking into account the chemical properties of the substance, after consultation with a doctor and under his supervision, admission is possible.
If there is no "Vidisik" in the pharmacy
Few people have not encountered such a situation when they came to the pharmacy and were not able to purchase the right drug, and there simply is no time to search for it. You can buy an analog that resembles Vidisik in pharmacological properties. The pharmacy sells various products that can partially or completely replace the gel.
All preparations containing carbomer are produced in Europe and America, therefore the quality standards of these dosage forms are at their best.
Full analogs of the Vidisik gel should contain only carbomer, have a gel-like consistency. These include:
- Sikapos. German-made eye gel in a small tube weighing ten grams. Contains carbomer. Used up to five times a day, from one to three drops. The peculiarity of the tool is that when interacting with a tear fluid, the base dissolves under the action of salts, and the sclera is moistened with the active substance, removing inflammation and irritation of the mucous membrane.
- Oftagel. The difference between this tool and others is that in addition to carbomer, in a larger amount (2.5 mg per gram of the drug), it contains benzalkonium chloride, which is not recommended for use with contact lenses. Before instillation of the lens, it is advisable to remove, and after the procedure, wait fifteen minutes. It is used one to four times a day for the treatment of "dry eye syndrome", inflammation of the conjunctiva and cornea of the eye. It is made in Finland. If there are no full analogues in the pharmacy, then you can replace it with other means that do not differ from the Vidisik gel indications, but which include hypromellose.
- "Artificial tear." It is produced by the Belgian company Alkon, which has long been known in the pharmaceutical market as a company dealing exclusively with eye preparations. The composition includes hypromellose, which, when interacting with the mucosa, forms a thin protective barrier and helps retain moisture in the cornea of the eye. Since the product has only barrier properties, it can be used by pregnant and lactating, as well as with caution, children. It is prescribed for dry mucous membranes, burning sensation, discomfort and pain. Adults are prescribed one or two drops if necessary.
Secret to the whole world
If a few years ago, the prescribed eye gel could cause a lot of questions, today manufacturers can enjoy the popularity of this drug. Many patients who have tried it continue to use Vidisik gel. Instructions for use help to understand how to use it correctly, in what dosage.
The main reason why this dosage form is loved by ordinary people is a convenient form of release. Due to its thick consistency, it is easy to drip it by squeezing a couple of drops per eyelid, without worrying about spoiled makeup or profuse tearing after use.
In addition, consumers noted a convenient dropper dispenser. When you press the tube, a small amount of gel in the form of a pea comes out of the dispenser.
The downside is infrequent, but still allergic reactions. Their appearance is associated with the presence of cetrimide, a preservative and an antiseptic in the composition, contact with which adversely affects the tissues of the eye.
Reviews about the gel "Vidisik" almost all positive. The main advantage is the long shelf life of the gel, which allows you to use it to the last drop.
