- auxiliary components: benzalkonium chloride, sodium chloride, disodium phosphate dodecahydrate, concentrated hydrochloric acid and / or sodium hydroxide (for pH adjustment), purified water.
Pharmacological properties
Pharmacodynamics
Olopatadin - the active substance of Opatanol, belongs to the selective inhibitors of histamine H1 receptors. It inhibits the release of inflammatory mediators from mast cells, thereby exerting a pronounced antiallergic effect.
Olopatadine has no effect on dopamine, α-adrenergic, serotonin, and muscarinic acetylcholine receptors of types 1 and 2.
Pharmacokinetics
Systemic absorption of olopatadine when applied topically is low. The level of the maximum concentration of the substance in the blood plasma is in the range from 0.5 or less to 1.3 ng / ml and is reached within 2 hours.
The plasma half-life is approximately 3 hours. Olopatadin is excreted mainly in the urine, from 60 to 70% - unchanged.
Indications for use
Opatanol eye drops are used to treat symptoms of seasonal allergic conjunctivitis.
Contraindications

Overdose
With topical application of Opatanol, an overdose is unlikely.
In case of contact with the eyes, an excessive amount of solution is recommended to rinse them abundantly with warm water.
special instructions
With the development of allergic reactions, treatment with olopatadine should be discontinued.
Since benzalkonium chloride can be absorbed by eye contact lenses, lenses must be removed before instillation. They should be installed back no earlier than 20 minutes after instillation of the drug.
To avoid contamination of the dropper bottle and its contents, do not allow the pipette tip to touch any surfaces.
The bottle must be closed after each use.
In the case of prolonged / frequent use of Opatanol in patients with corneal pathologies or dry eye syndrome, the preservative benzalkonium chloride contained in the preparation can lead to superficial punctate keratitis or toxic ulcerative keratopathy.
Influence on the ability to drive vehicles and complex mechanisms
If, after using Opatanol, the patient feels a short-term decrease in vision clarity, it is not recommended to drive vehicles and perform work that requires a quick psychomotor reaction and high concentration of attention until vision is completely restored.
Application during pregnancy and lactation
In preclinical studies, no genotoxic, teratogenic, reproductive toxic or potential carcinogenic effects of olopatadin have been identified. Clinical study data are not available.
Due to the lack of sufficient experience on the use of Opatanol in pregnant and lactating women, it can be used in patients of this category when the expected therapeutic effect for the mother is higher than the potential risk for the fetus / child.
Pediatric use
It is not recommended to prescribe the drug to children under 3 years of age due to insufficient experience of use.

Opatanol reviews
Opatanol reviews are contradictory. For many users, the drug helps with exacerbation of seasonal allergic conjunctivitis, relieves puffiness, redness and inflammation of the eyes, and reduces lacrimation. In this case, the effect appears quickly and with minimal use of eye drops.
But some patients indicate the absence of any positive result from the use of Opatanol. Moreover, some of them note a worsening of the condition and the appearance of side reactions in the form of increased redness of the eyes, rhinitis, pharyngitis and dryness of the nasal mucosa.
Opatanol price in pharmacies
The price of Opatanol eye drops for a 5 ml bottle is approximately 490 rubles.
