Pharmacological action

Anti-allergic agent H1-histamine receptor blocker Pharmacodynamics :

Olopatadine is a potent, selective anti-allergic / antihistamine drug whose pharmacological effects develop through several different mechanisms of action. It is an antagonist of histamine (the main mediator of allergic reactions in humans) and prevents the histamine-induced release of inflammatory cytokines in conjunctival epithelial cells. The results of in vitro studies suggest inhibition of the release of pro-inflammatory mediators by conjunctival mast cells.

In patients with passable nasolacrimal ducts, topical application of olopatadine in the form of instillations into the conjunctival sac reduced the severity of nasal symptoms often associated with seasonal allergic conjunctivitis.

Olopatadine has no clinically significant effect on pupil diameter.

Pharmacokinetics:

Suction

Olopatadine undergoes systemic absorption, like other drugs intended for topical use. However, plasma concentrations of olopatadine after topical application in ophthalmology are low and range from below the level of quantitative determination ( The claimed plasma concentrations are 50-200 times lower than those with oral therapeutic doses of olopatadine.

Deduction

According to pharmacokinetic studies of oral forms of olopatadine, the half-life is from 8 to 12 hours, the drug is excreted mainly by the kidneys. 60-70% of the administered dose is excreted unchanged in the urine, and low concentrations of 2 metabolites – mono-desmethyl and n-oxide-are also detected in the urine.

Due to the fact that olopatadine is mainly excreted unchanged by the kidneys, impaired renal function leads to a change in the pharmacokinetics of olopatadine, leading to a significant (2.3 times) increase in the concentration of olopatadine in plasma in patients with severe renal insufficiency (creatinine clearance 13 ml/min). Due to the fact that the concentration of olopatadine in plasma after its topical application in the form of instillations is 50-200 times lower than with oral therapeutic doses, there is no need to change the dosage regimen in elderly patients or in patients with impaired renal function. Since the hepatic elimination pathway is not the primary route for olopatadine, no dose adjustment is required when used in patients with impaired liver function.

After oral use of 10 mg of olopatadine to patients on hemodialysis, the plasma concentration of olopatadine was significantly lower on the day of hemodialysis compared to days when hemodialysis was not performed. This indicates that the elimination of olopatadine by hemodialysis is possible.

According to the results of comparative studies of the pharmacokinetics of the oral dosage form of olopatadine at a concentration of 10 mg in young (mean age – 21 years) and elderly patients (mean age 74 years), there were no significant differences in plasma concentrations of olopatadine, plasma protein binding, and parameters of drug excretion in unchanged form and in the form of metabolites.

Indications

Treatment of seasonal allergic conjunctivitis symptoms.

Use during pregnancy and lactation

Fertility

Studies of the effect of topical olopatadine in ophthalmology on human fertility have not been conducted.

Pregnancy

Information on topical use of olopatadine in ophthalmology in pregnant women is not available or limited. In animal studies, data have been obtained on the toxic effect of olopatadine on reproductive function with systemic use. It is not recommended to use olopatadine during pregnancy and women of childbearing age who do not use contraceptive methods.

Breast-feeding period

The excretion of olopatadine in breast milk was noted when using the drug in animals. The risk for newborns and children cannot be excluded. It is not recommended to use the drug Olopatallerg during breastfeeding.

Recommendations for use

Locally.

Instill 1 drop into the conjunctival sac of the affected eye 2 times a day (with an interval of 8 hours).

The duration of treatment is up to four months.

If necessary, the drug can be used in combination with other drugs. In this case, the interval between their use should be at least 5 minutes.

Elderly people.

There is no need to adjust the dosage for elderly patients.

Children from 3 years old.

Olopatallerg can be used in the same doses as in adults.

Kidney or liver failure

No studies have been conducted in patients with renal or hepatic insufficiency regarding the use of olopatadine in the form of eye drops. However, no dose adjustment is expected to be necessary in patients with renal or hepatic insufficiency.

Do not touch the tip of the bottle to the eyelids, the skin of the periocular area and other surfaces to avoid microbial contamination of the drug. Close the lid tightly after using the product.

Contraindications

Hypersensitivity to the components of the drug, pregnancy and lactation, age up to 3 years.

With caution:

In patients with concomitant dry eye syndrome and corneal diseases.

Side effects

General information about the adverse event profile

In clinical trials involving 1,680 patients, the dosage regimen ranged from 1 to 4 drops per day, the duration of therapy was up to 4 months, and olopatadine was used both in monotherapy and in combination with loratadine at a dosage of 10 mg. The overall incidence of adverse events was about 4.5%, while discontinuation of participation in the clinical trial due to the development of adverse reactions was observed only in 1.6% of cases. In the course of clinical studies, no serious adverse events were observed either on the part of the visual organ or on the part of the body as a whole. The most common treatment-related adverse reaction was eye discomfort, which was reported in 0.7% of patients.

Tabular data about undesirable events

The following adverse events were reported during clinical trials and post-marketing use of the drug and are classified according to the following gradation of the frequency of adverse events: very common (≥1/10), common (≥1/100 to <1/10), infrequent (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1000), very rare ( Within each group, adverse events are listed in order of decreasing severity.

In very rare cases, the use of phosphate-containing drops in patients with concomitant significant corneal damage has resulted in corneal calcification.

Interaction

Interaction studies of olopatadine with other drugs have not been conducted. In vitro studies have demonstrated the absence of inhibition of metabolic reactions mediated by cytochrome P 450 isoenzymes 1A2,2C8,2C9,2C19,2D6,2E1AND 3A4. According to the results obtained, the probability of olopatadine entering into metabolic reactions when co-administered with other drugs is estimated as low.

Overdose

There is no information about the development of toxic effects if an excessive amount of the drug is accidentally introduced into the conjunctival cavity or if it is accidentally swallowed. If overdose develops due to accidental ingestion, treatment should be supportive.

Special instructions

Olopatadine hydrochloride is an anti-allergic/ antihistamine drug for topical use in ophthalmology, and, despite topical use, can be absorbed into the systemic circulation. If severe hypersensitivity reactions occur, the drug should be discontinued.

The drug contains benzalkonium chloride, which can be absorbed by soft contact lenses and cause eye irritation. It is necessary to remove contact lenses before instillation and install them again no earlier than 15 minutes after instillation of the drug. With frequent or prolonged use of the drug, benzalkonium chloride can cause the appearance of pinpoint keratitis or toxic ulcerative keratopathy in patients with dry eye syndrome or corneal pathology. Influence on the ability to drive vehicles and mechanisms:

Olopatadine does not significantly affect the ability to drive vehicles and mechanisms. If blurred vision is observed immediately after instillation, it is necessary to wait for the restoration of clarity of visual perception before driving vehicles and mechanisms.
