Pharmacological properties
Pharmacodynamics
Oxymetazoline belongs to the group of alpha-agonists for topical use. Has a vasoconstrictor effect. When administered intranasally, it reduces swelling of the mucous membrane of the upper respiratory tract and nasal discharge. Restores nasal breathing.
Elimination of swelling of the nasal mucosa helps restore aeration of the paranasal sinuses and middle ear cavity, which reduces the likelihood of bacterial complications (sinusitis, sinusitis, otitis media). When used locally intranasally in therapeutic concentrations, it does not irritate or cause hyperemia of the nasal mucosa.
Oxymetazoline begins to act from 25 seconds. The duration of action of the drug is up to 12 hours.
Pharmacokinetics
When administered locally intranasally, oxymetazoline does not have a systemic effect. The half-life of oxymetazoline when administered intranasally is 35 hours. 2.1% of oxymetazoline is excreted by the kidneys and about 1.1% through the intestines.

system and the central nervous system. In these cases, it is recommended to be careful when driving vehicles and engaging in other potentially hazardous activities that require increased concentration and speed of psychomotor reactions.
Directions for use and doses

In rare cases: after the effect of the drug wears off, a feeling of “stuffiness” in the nose (reactive hyperemia).
Frequency unknown: dryness of the mucous membranes of the mouth and throat, increased volume of secretions released from the nose.
Side effects caused by the systemic action of the drug:
Uncommon: Quincke's edema, itching.
Rarely: increased blood pressure, headache, dizziness, palpitations, tachycardia, anxiety, irritability, sleep disturbance (in children), nausea, insomnia, exanthema, blurred vision (if it gets in the eyes).
Very rare: restlessness, fatigue, drowsiness, sedation, hallucinations, convulsions, respiratory arrest (in infants).
Long-term continuous use of vasoconstrictor drugs can lead to tachyphylaxis, atrophy of the nasal mucosa and recurrent swelling of the nasal mucosa (rhinitis medicamentosa).

Clinical signs of intoxication with imidazole derivatives can be nonspecific and unclear, since phases of hyperactivity are replaced by phases of depression of the central nervous system, cardiovascular and respiratory systems.
Symptoms: anxiety, restlessness, hallucinations, convulsions, decreased body temperature, lethargy, drowsiness, coma, constriction or dilation of pupils, fever, sweating, pallor, cyanosis, palpitations, bradycardia, arrhythmia, cardiac arrest, increased blood pressure, decreased blood pressure , nausea, vomiting, respiratory depression, respiratory arrest.

Interaction with other drugs
When used concomitantly with monoamine oxidase inhibitors (during the previous 2 weeks and within 2 weeks after their discontinuation), tricyclic antidepressants or other drugs that increase blood pressure, an increase in blood pressure may occur. The drug slows down the absorption of local anesthetic drugs and prolongs their effect.
Co-administration of other vasoconstrictor drugs increases the risk of side effects.
