Normatin (timolol) eye drops 0.5% 5 ml. vial


Increased intraocular pressure of various origins( open-angle glaucoma, aphakic glaucoma, secondary glaucoma); angle-closure glaucoma in combination with myotic agents; ocular hypertension.



Normatin composition
Main active ingredient: timolol.
Excipients: sodium phosphate monobasic, sodium phosphate disubstituted, benzalkonium chloride solution, sodium hydroxide, water for injection.

Release form
It is produced in the form of eye drops, it is sold in pharmacy sales in dropper bottles with a volume of 5 ml, in dosages of 5 mg of timolol per 1 ml of solution.

Pharmacological properties
This ophthalmic preparation Normatin belongs to antiglaucoma drugs.
The main active ingredient is timolol, a non-selective beta-blocker.
Its use leads to a decrease in both increased and normal intraocular pressure due to the mechanism of action, which is associated with the ability to reduce the release (secretion) of aqueous humor and improve its outflow from the eyes.
Does not cause changes in pupil size and does not affect the ability of the eyes to accommodate.
It has the property of inhibiting beta receptors (β1), which are localized mainly in the muscles of the heart. Also has a blocking effect on β2 receptors. As a result of a decrease in the stimulating effect of catecholamines on the myocardium, the conduction of atrioventicular blockade slows down. As a result, the frequency of contractions of the heart muscle decreases, and then the minute volume of the myocardium.
The use of this drug Normatin also causes sensitization of the upper and lower airways.
Has no sympathomimetic or local anesthetic effect.
Long-term use can cause the development of resistance to timolol.

This Normatin ophthalmic solution is used to treat:

  • increased intraocular pressure (glaucoma, or ocular hypertension, including congenital);
  • chronic open-angle glaucoma, in combination with miotic drugs;
  • glaucoma, which is a consequence of lens removal (glaucoma in aphakia).

The specified drug is not used if the patient has (or has ever been observed before) a hypersensitivity (allergy) reaction to the use of timolol or one of the other components of the drug.
Also contraindicated for:

  • bronchial hyperreactivity;
  • bronchial asthma, incl. in the anamnesis;
  • chronic obstructive airways disease;
  • sinus bradycardia;
  • sick sinus syndrome, including sinoauricular block;
  • atrioventricular block II or III degree, which is not controlled by a pacemaker;
  • severe heart failure;
  • high degree of atrioventricular block;
  • congestive heart failure;
  • cardiogenic shock.

Care should be taken when prescribing to patients who have severe peripheral circulatory disorders (in particular, Raynaud’s syndrome).

Application during pregnancy and lactation
Treatment of pregnant women is extremely undesirable, only for serious reasons.
Breastfeeding should be suspended during treatment.

Method of administration and dosage
These Normatin drops are intended only for instillation into the conjunctival region of the eye.
The initial dose is 1 drop 2 times a day, in a dosage of 2.5 mg of timolol per 1 ml of the drug.
If this dosage was sufficient, it is worth reducing the dosage before using 1 drop 1 time per day. The pressure is assessed 4 weeks after the start of timolol therapy.
With an increase in pressure, the dose of the drug also increases (1 drop at a dosage of 5 mg of timolol 2 times a day).
The patient should remember that with glaucoma, regular monitoring of intraocular pressure is necessary. The course of treatment can be long.
Patients with a highly pigmented iris should take into account that their pressure reduction will be less effective.

Overdose with this drug usually does not cause any particular adverse events due to its low toxicity.
In rare cases, with prolonged significant excess of the dosage, the following were observed:

  • lowering blood pressure;
  • congestive heart failure, cardiogenic shock;
  • bradycardia, cardiac arrest;
  • respiratory disorders, in particular, bronchospasm;
  • gastrointestinal disorders;
  • confusion of consciousness;
  • convulsions.

In case of an overdose, atropine, glucagon, diazepam, beta-sympathomimetics are recommended. The use of pacemakers is recommended.

  • angioedema, allergic urticaria, rash, itching, anaphylactic reactions, facial edema, redness;
