Loratavel is an anti-allergic drug, H ₁ -histamine receptor blocker.

Release form and composition

The drug is produced in the form of tablets: flat-cylindrical, round, almost white or white, with a line and a chamfer (10 pieces in a blister strip, in a cardboard box 1, 2 or 3 packages; 10, 20 or 30 pieces in a polymer can, in a cardboard box 1 can and instructions for the use of Loratavel).

1 tablet contains:

• active substance: loratadine - 10 mg;
• additional substances: sodium carboxymethyl starch (sodium starch glycolate, primogel), magnesium stearate, lactose monohydrate (milk sugar), corn starch, microcrystalline cellulose, talc, colloidal silicon dioxide (aerosil).

Pharmacological properties

Pharmacodynamics

Loratadine is a tricyclic compound with a pronounced antihistamine effect and related to blockers of peripheral H ₁ -histamine receptors. The active substance has a quick and long-term antiallergic effect, starting to show an effect within the first 30 minutes after oral administration. The antihistamine effect reaches its maximum after 8-12 hours after the onset of action and lasts over 24 hours. The drug does not affect the central nervous system and does not pass through the blood-brain barrier.

When used in the recommended doses, the drug does not show sedative or anticholinergic effects - it does not affect the speed of psychomotor reactions and does not lead to drowsiness. During therapy with Loratavel, there is no prolongation of the QT interval on the electrocardiogram (ECG), provoked by the intake of the drug.

During long-term use of the drug, no clinically significant changes in physical examination data, vital signs, laboratory test results or ECG were recorded.

The active substance practically does not affect the cardiovascular system or the activity of the pacemaker and does not suppress the reuptake of norepinephrine.

Loratadine does not show significant selectivity for H ₂ -histamine receptors.

Pharmacokinetics

The drug is intensively absorbed in the gastrointestinal tract (GIT). The period of reaching the maximum concentration (T _max) of the active substance in the blood plasma is 1-1.5 hours, and its active metabolite (desloratadine) is 1.5-3.7 hours. Loratavel's intake with food does not change the maximum concentration (C _max) loratadine and desloratadine, however, leads to an increase in their T _max by 1 hour, while not affecting the therapeutic effect of the agent.

The plasma protein binding of loratadine is 97-99%, and desloratadine is 73-76%. The active metabolite of the active substance is formed with the participation of the cytochrome P450 3A4 system and, to a lesser extent, P450 2D6.

Over a period of more than 10 days, an average of 40% of the oral dose used is eliminated through the kidneys and 42% through the intestine, mainly in the form of conjugated metabolites. Approximately 27% of the dose of the drug after administration is excreted in the urine within 24 hours, while less than 1% of the active substance is unchanged.

The bioavailability of loratadine and its main metabolite is dose-dependent. The half-life (T _½) of loratadine can vary from 3 to 20 hours (mean value - 8.4 hours), and desloratadine - from 8.8 to 92 hours (mean value - 28 hours).

In patients with chronic kidney disease, _Cmax and the area under the concentration-time curve (AUC) of loratadine and desloratadine increase compared with those in patients with normal renal function. T _{½ of the} active substance and its main derivative do not differ from those of healthy volunteers. In patients from this group, hemodialysis does not affect the pharmacokinetic characteristics of loratadine and its main metabolite.

In the presence of alcoholic liver damage, C _max and AUC of loratadine and desloratadine increase by 2 times compared with these indicators in normal liver activity, T _½ increases depending on the severity of the lesion.

In elderly and younger healthy volunteers, the pharmacokinetic profiles of loratadine and its active derivative were comparable. In elderly patients, T _½ loratadine is 6.7–37 hours (average 18.2 hours), desloratadine - 11–39 hours (average 17.5 hours).

Indications for use

Loratavel is recommended for use to eliminate symptoms such as sneezing, rhinorrhea, itching of the nasal mucosa, watery eyes, itching and burning sensation in the eyes associated with the following diseases:

• age up to 3 years and body weight less than 30 kg;
• lactation period;
• glucose-galactose malabsorption, lactose intolerance, lactase deficiency;

Loratavel, instructions for use: method and dosage

Loratavel tablets are taken orally, regardless of the time of the meal.

Children from 3 to 12 years old with a body weight of more than 30 kg, adolescents over 12 years old, adults, including elderly patients, are recommended to take the drug once a day at a dose of 10 mg (1 tablet).

Side effects

In the course of clinical studies involving children 2–12 years old who received Loratavel, more often than in patients in the placebo group, there were disorders in the form of fatigue (1%), nervousness (2.3%), headache (2.7%) …

In studies involving adult patients, adverse reactions, the frequency of development of which was higher than with placebo, were recorded in 2% of patients using Loratavel. These side effects included insomnia (0.1%), headache (0.6%), increased appetite (0.5%), drowsiness (1.2%).

In addition, in the post-marketing period, there were extremely rare reports (<1/10 000) of the following adverse events: dry mouth, alopecia, fatigue, dizziness, gastrointestinal disorders, including nausea, gastritis; allergic reactions in the form of rash, anaphylaxis, including angioedema; liver dysfunctions, tachycardia, palpitations, convulsions.

Overdose

Symptoms of a loratadine overdose include: headache, drowsiness, tachycardia.

In case of suspicion of an overdose, an urgent need to consult a doctor. In this condition, symptomatic and supportive therapy is carried out, gastric lavage or intake of adsorbents (including crushed activated carbon with water) may be prescribed. With the help of hemodialysis, the drug is not excreted from the body. After carrying out all the prescribed measures, the patient should be under close supervision.

special instructions

If during the period of drug therapy it is necessary to conduct allergic skin tests, it must be stopped at least 48 hours before these tests are performed, since loratadine can affect their results.

Influence on the ability to drive vehicles and complex mechanisms

The negative impact of Loratavel on the ability to drive motor vehicles or other complex and potentially dangerous mechanisms has not been established. At the same time, when carrying out such activities against the background of therapy, caution should be exercised in view of the possible appearance of drowsiness.

Application during pregnancy and lactation

The safety of loratadine therapy in pregnant women has not been established. The use of Loratavel during pregnancy is possible only if the expected benefit for the woman significantly exceeds the possible threat to the health of the fetus.

Loratadine and desloratadine are excreted in breast milk, as a result of which, if it is necessary to treat with a drug during breastfeeding, it is necessary to transfer the child to artificial feeding.
