Drops from eye pressure: classification of drugs

Drops from eye pressure are the means of first aid in case of appearance of such diseases as glaucoma. This pathology is characterized by violation of the outflow of intraocular fluid, which can increase intraocular pressure. Pressure fluctuations, which in no way affect the eyesight, don’t need medical treatment. But in cases of elevated intraocular pressure drops to its normalization perfectly cope with the task.

 

All medicines for lowering intraocular pressure are divided into several groups:

  • Substances that inhibit carbonic anhydrase. Medicines in this group help to reduce production of intraocular fluid. These drugs have some side effects: burning and itching after use, the redness of the protein shell of the eye, bitter taste.
  • Medicines prostaglandin series increase the excretion of aqueous fluid from blood vessels. Their side effect is the possible darkening of the iris or lengthening lashes.
  • Beta-receptorul have action which is directed on decrease in production of intraocular fluid. It often happens that the medicinal substances of this group are assigned in combination with prostaglandins. These drugs can have a direct effect on the cardiovascular system because of the placement of the beta-receptors in cardiomyocytes.

    Inhibitors of carbonic anhydrase

    These funds have several advantages in comparison with drugs of other groups. They are high effectiveness, no side effects, which occur when effects on the cardiovascular or respiratory system. Medicines of this group must be careful not be taken by people who suffer from diseases of the genitourinary system. Often these drugs are recommended for use twice a day, it should be noted that the carbonic anhydrase inhibitors cannot be assigned in the complex therapy with beta-blockers or prostaglandins.

    The most common drug is Diacarb, which can be used to reduce intraocular pressure or the treatment of acute and subacute glaucoma.

    Analogues of drugs are prostaglandin series

    Prostaglandins are effective drugs against glaucoma, which have the highest safety profile compared to other drops for glaucoma. But it is worth noting that a significant effect when using this group of drugs comes only after two hours of use, maximum effect is reached after twelve hours.

    The list of drugs is quite wide — it is Travatan, Xalatan, Tafluprost, etc., although on the pharmaceutical market they appeared in so long ago. But thanks to the high efficiency of drugs and the prolonged duration of their action, they are major drugs against glaucoma. The main advantage is frequency of use: one instillation per day would be sufficient.

    The mechanism of action of drugs prostaglandin series is based on improving the outflow of intraocular fluid. The acceleration of the outflow is ensured by the involvement of an additional pathway of excretion of liquid.
    But like all drugs, prostaglandins have a number of side effects, that still does not make them ideal:

    • There is a slight redness of the eyes due to the fact that the expanded mesh surface capillary vessels.
    • It is possible to change the iris. Usually, its color becomes darker.
    • Due to the fact that prostaglandins are biologically active substances, which are formed enzymatically, they can influence some of the processes. When used as tools for glaucoma may increase the growth of eyelashes: they become longer, thicker and can change color to darker. However, this side effect few people upset, which is why prostaglandins took pride of place in some cosmetic companies.

    The use of beta-blockers in the treatment of glaucoma

    This group of pharmacological drugs that unlike other substances aimed at the treatment of glaucoma can reduce the production of intraocular fluid. Beta-blockers have a rapid effect, which starts to occur after 20-30 minutes after applying the drug. The maximum effect is reached two hours after instillation, so often the drug is used more than twice a day. Beta-blockers can be used in combination with prostaglandins to increase the duration of therapeutic effects, which in turn will contribute to reducing the number of instillation.

    Drops intraocular pressure in this group are fairly common. It might be Timolol, Okumed, AKUMAL, etc. depending on financial possibilities, you can choose any means, especially because almost all of them there is one active ingredient.

    The main disadvantage of these pharmaceutical drugs is many side effects associated with their indirect effects on the cardiovascular and respiratory system. So medicinal substances in this group are not recommended for patients with certain heart diseases, presence of asthma or chronic obstructive pulmonary disease.

    The combined funds against glaucoma

    To summarize the drug the therapeutic effects of several drug groups are created by their combination. There are also for the treatment of elevated intraocular pressure:

  • Drug Xalacom is a complex of beta-blocker and prostaglandin at the expense of latanoprost and timolol. The main advantage of this drug is a double effect which manifests itself in a long action and reducing the secretion of intraocular fluid.
  • Drops fotil — a combination of Pilocarpine and timolol. It has a similar effect of the previous drug because of the combination of almost the same active ingredients.
