Pharmacy shelves are crowded with a variety of vasoconstrictor drugs, advertising slogans promise to get rid of the runny nose, restore freedom of breathing and sense of smell. Annual sales of vasoconstrictor drugs in Russia amount to hundreds of millions of packages, and the profit from their sale is tens of billions of rubles. Let's find out whether these over-the-counter medications are so harmless and are they really necessary for us in everyday life?
Vasoconstrictor drugs (syn.: decongestants, vasoconstrictors, simatomimetics) have been widely used for many years in the treatment of diseases of the nose and paranasal sinuses. We will talk about those that are used topically, that is, in the form of nasal drops or aerosols.
Sympathomimetics are one of the most ancient drugs used in medicine. Ephedrine has been known as the active ingredient in the ancient Chinese medicine Ma Huang for over 5,000 years. Another powerful vasoconstrictor, cocaine, has been used for more than a hundred years to anesthetize and anemize the mucous membrane of the respiratory tract. Interestingly, naphazoline (the first representative of the chemical group of imidazolines, which includes most of the currently known topical decongestants) was synthesized by the German chemist Adolf Sonn in Nazi Germany. Namely, at the end of the thirties of the twentieth century in Koenigsberg. Naphazoline is a short-acting vasoconstrictor that most often causes unwanted side effects and complications. By the way, the first reports of the so-called “naphazoline addiction” appeared in medical journals very soon, already in the early forties, first in Germany and soon in Canada. Later, safer and more effective vasoconstrictors were synthesized - oxymetazoline, xylometazoline, tetrizoline, etc.
Mechanism of action. Vasoconstrictor drugs, as their name implies, cause narrowing (spasm) of blood vessels by acting on receptors in the vascular wall. In the nasal cavity, there are areas, mainly the inferior turbinates, where rich vascular plexuses are located under the mucous membrane. Decongestants, when they enter the nasal mucosa, constrict the vessels in these plexuses and the inferior turbinates decrease in size. At the same time, the lumen of the nasal cavity increases, the volume of air passing through the nose increases, and, accordingly, nasal breathing improves.
Local vasoconstrictor drugs, which are used to improve nasal breathing, are divided into two main groups, depending on which receptors of the vascular wall they act on. Those that act on α1-adrenergic receptors have a milder and shorter-lasting effect (less than 2 hours). The second group of drugs selectively acts on α2-adrenergic receptors, their vasoconstrictor effect is more pronounced (approximately 2 times higher than that of the previous group), the vasoconstrictor effect lasts longer (up to 8 hours). This group of drugs is mainly used - imidazoline derivatives, the earliest of which is naphazoline. The table shows both groups of decongestants with trade names.

Indications
Vasoconstrictors effectively improve nasal breathing in all categories of patients, regardless of the cause of the disease. They work equally well for allergic, infectious and vasomotor rhinitis. It has been proven that the administration of decongestants reduces the duration of an acute runny nose by a third - from 6 to 4 days. For allergic rhinitis, the administration of decongestants in a short course (no more than 10 days) may also be justified. By reducing swelling of the nasal mucosa, they allow antiallergic drugs (topical intranasal corticosteroids and antihistamines) to penetrate more deeply. Decongestants are often prescribed situationally, for example, during air travel in persons with rhinitis or sinusitis to prevent otitis media. Or in acute otitis media to restore the function of the auditory tube. However, this practice has not yet received scientific confirmation. Apart from restoring nasal breathing, these drugs have no effect on other symptoms of rhinitis: they do not reduce the number of sneezes, and experimental studies in animals show that when treated with vasoconstrictors, the amount of nasal discharge even increases.
Side effects
Most vasoconstrictor drugs are over-the-counter drugs—patients usually buy them without consulting a doctor. Moreover, patients often use these drugs despite doctor's warnings. However, decongestants can cause serious side effects.
Effects on the cardiovascular system
Patients often note that the use of vasoconstrictor drugs causes a deterioration in their general condition, headache, palpitations, etc. Reports in the literature also suggest that long-term, and sometimes even situational, use of decongestants, primarily naphazoline, and to a lesser extent oxymetazoline, may be accompanied by headache caused by segmental spasm of cerebral vessels, and even lead to ischemic and hemorrhagic strokes brain.
Effect on the vascular system of the nasal cavity
All topical vasoconstrictor drugs are, to one degree or another, capable of causing the development of rebound syndrome. Long-term (more than 10 days) use of topical vasoconstrictor drugs causes severe swelling of the nasal mucosa, leading to its irreversible changes and the occurrence of drug-induced rhinitis.
Short courses of treatment with topical decongestants, such as oxymetazoline and xylometazoline, do not lead to any significant functional and morphological changes in the nasal mucosa. However, in individuals with pre-existing nasal hyperreactivity (vasomotor rhinitis, vegetative-vascular dystonia), even a short-term course of treatment with nasal decongestants can lead to the formation of persistent drug dependence.
Effect on the nasal mucosa
Experimental studies have shown that the use of Naphthyzin for 6 months leads to polypous changes in the nasal mucosa, slowing down the movement of cilia and a complete loss of the protective function of the nasal mucosa.
Systemic toxicity
The systemic toxic effect of vasoconstrictors most often manifests itself in childhood. Decongestants should be administered with particular caution to children under 2 years of age because the current interval between therapeutic and toxic doses in this age group is short. Among all nasal decongestants, short-acting imidazoline derivatives (in particular, naphazoline) have the most pronounced undesirable topical and systemic effects. Poisoning with naphazoline drugs is one of the most common reasons for hospitalization of children in toxicology departments. The reasons for the development of a systemic toxic effect in children are exceeding a single dose and frequency of taking drugs, the use of drugs with a concentration adapted for older age, non-standardized methods of using decongestants, such as rinsing the nose by moving a decongestant solution, and even taking a decongestant solution orally.
In many countries, naphazoline preparations are not recommended at all for use in pediatric practice. In Russia, its use is permitted in children over 2 years of age, but it is emphasized that between the ages of 2 and 6 years, a 0.025% solution of naphazoline should be used. However, in practice, implementation of these recommendations is problematic, since official solutions of naphazoline are produced only in 0.05% and 0.1% concentrations. Considering this, the use of naphazoline and its derivatives in young children and preschoolers is inappropriate.
There is no information about the teratogenic effect of topical nasal decongestants, but due to the increased susceptibility of pregnant women to the development of tachyphylaxis syndrome, the use of vasoconstrictor drugs in them should be limited to the minimum possible doses and timing.
Decongestants: from proven remedies to improved combinations
The modern classification of rhinitis still continues to be revised [1,2]. This is due to the fact that the universal clinical signs of rhinitis can have different pathogenesis: infectious, allergic, occupational, hormonal, drug. Doctors often make a diagnosis at their own discretion, continuing to use different and mutually exclusive concepts to define the same conditions: “rhinopathy”, “rhinosinusopathy”, “vasomotor, allergic”, etc. This leads not only to errors when conducting epidemiological analysis, but and to difficulties and difficulties in interpreting the results of clinical studies. According to the report of the International Consensus on the Diagnosis and Treatment of Rhinitis (1996), rhinitis is classified as follows: allergic (seasonal and year-round), infectious (acute and chronic) and other types (idiopathic, occupational, hormonal, drug, caused by irritants, food, psychogenic, atrophic) [1]. A slightly different classification used in Russia distinguishes allergic, infectious, non-allergic eosinophilic, vasomotor, hypertrophic and atrophic rhinitis. Depending on the duration, rhinitis is divided into acute and chronic [3]. According to foreign data, rhinitis is proposed to be classified into allergic and non-allergic, the latter being divided into subtypes not associated with allergens, infectious agents and anatomical defects - non-allergic rhinopathy (vasomotor rhinitis), non-allergic rhinitis with eosinophilia, atrophic rhinitis, drug-induced rhinitis, hormonal-induced rhinitis, including rhinitis of pregnancy, and nasal liquorrhea [4]. The most complete classification of rhinitis according to T.I. Garashchenko (1998), which divides rhinitis into 6 positions: etiology, clinical course, morphological nature of the pathological process, periods of the disease, functional state and age characteristics, but in real clinical practice it is complex and not entirely convenient. However, most current classifications are based on the etiological factor contributing to the occurrence of rhinitis and its morphological characteristics. However, the issue of classification of rhinitis still remains controversial. Thus, the morphological picture of rhinitis can undergo changes as the disease progresses: hypertrophy of the mucous membranes of the nasal turbinates can be the final stage of any form of rhinitis, except atrophic. Post-traumatic or postoperative rhinitis, found in some classifications, is almost always bacterial in nature. We should not forget that rhinitis can be a manifestation of other diseases (sinusitis, adenoiditis, liquorrhea). The exception is allergic rhinitis, for which there is the greatest certainty in both diagnosis and treatment strategy. Thus, according to the Allergic rhinitis and its impact on asthma initiative (ARIA, 2001), allergic rhinitis is classified into intermittent (seasonal) and persistent (year-round) and their severity is determined as mild, moderate or severe [5,20]. According to ICD-10, the following classification is considered for statistical processing: J00 Acute nasopharyngitis (runny nose) J30 Vasomotor and allergic rhinitis • J30.0 Vasomotor rhinitis • J30.1 Allergic rhinitis caused by pollen • J30.2 Other seasonal allergic rhinitis • J30.3 Other allergic rhinitis • J30.4 Allergic rhinitis, unspecified J31 Chronic rhinitis, nasopharyngitis and pharyngitis • J31.0 Chronic rhinitis • J31.1 Chronic nasopharyngitis • J31.2 Chronic pharyngitis. Most often, general practitioners encounter rhinitis of viral and allergic etiology. Infectious diseases of the upper respiratory tract are diagnosed year-round, with a peak incidence in the autumn-winter period and are most often associated with viral infections. According to statistics, acute respiratory viral infection (ARVI) is the most common infectious disease in developed countries. On average, an adult gets ARVI at least 2–3 times per year, and children 2–3 times more often. The duration of acute viral rhinitis is 7–10 days. The danger is posed by complications that can develop against the background of rhinitis: inflammation of the paranasal sinuses (sinusitis, frontal sinusitis, ethmoiditis) and otitis media. As for allergic rhinitis, epidemiological data indicate that it affects, to varying degrees of severity, from 10 to 30% of adults and up to 40% of children [4–7]. The importance of this problem is also due to the fact that allergic rhinitis is closely related to such very common diseases as acute and chronic sinusitis, allergic conjunctivitis, and is one of the decisive risk factors for the development of bronchial asthma or already accompanies and aggravates it. For example, of 2580 patients with bronchial asthma (62% with atopy), 80.7% had indications of seasonal rhinitis, and in 72% of cases, exacerbation of rhinitis was accompanied by worsening asthma. In cases where asthma control was achieved (40.3% of patients), most patients used drugs to treat rhinitis [8]. Regardless of the etiology, the main pathogenetic link in the vast majority of diseases of the nasal cavity, paranasal sinuses and middle ear is swelling of the mucous membrane. It is impossible to consider rhinitis and not take into account its close relationship with the paranasal sinuses and the auditory tube. Swelling of the mucous membrane and hypersecretion in the nasal cavity inevitably complicate ventilation and impair mucociliary clearance, which creates conditions for the development of acute inflammation of the middle ear and paranasal sinuses, which, as a rule, are complicated by the addition of a bacterial infection. In most cases, patients with acute inflammatory diseases of the upper respiratory tract begin treatment primarily with available, over-the-counter and “harmless” symptomatic drugs. The share of medicines aimed at treating runny nose and cough in Russia is about 30% of the entire medicine market (according to DSM Group). Research shows that for 70–80% of patients the greatest problem that worsens the quality of life is the feeling of nasal congestion [8,13,14], so an important task is to restore nasal breathing. And this is due not only to the discomfort that rhinitis causes, but also to the fact that swelling, hypersecretion and a sharp decrease in the activity of the ciliated epithelium create ideal conditions for the attachment of infectious agents. In this regard, it is necessary to facilitate nasal breathing and elimination of secretions from the nasal cavity by prescribing local vasoconstrictors. Rhinorrhea and nasal congestion are natural stages of the inflammatory process, and therefore the rate at which this condition progresses depends on the effectiveness of anti-inflammatory treatment. However, in practice, anti-inflammatory nasal drugs are not often used, because in each case, an individual choice of drug is required depending on the etiology of rhinitis, which presents certain difficulties. Unfortunately, there are no universal anti-inflammatory drugs. At the same time, vasoconstrictor over-the-counter nasal medications, which are suitable for a wide range of patients, quickly alleviate the patient’s condition, although they do not affect the nature of the inflammation. The use of local therapy allows you to quickly stop the pathological process, avoid complications that accompany rhinitis and, in some cases, abandon the use of antibiotics, mucolytics and systemic anti-inflammatory drugs. Local therapy has a number of huge advantages: a quick effect, a direct effect on the mucous membrane, the creation of a high concentration of the drug in the area of inflammation, the ability to use small concentrations of the drug, the absence of a systemic effect. The form of release of the drug is also of great importance. Nasal drops are difficult to dose, since most of the instilled drug flows down the bottom of the nasal cavity into the pharynx. In this case, the required therapeutic effect is not achieved, and there is a risk of overdose. Therefore, it is more preferable to use nasal sprays that allow uniform irrigation of the nasal mucosa in small concentrations [15]. There are a huge variety of decongestants on the domestic market: “Naftizin”, “Xymelin”, “Nazol”, “Dlyanos”, “Tizin”, “Nazivin”, “Otrivin”. They all differ in composition, duration of action, and have advantages and disadvantages, but the mechanism of action of all drugs is fundamentally the same. Decongestants, being α-adrenergic agonists, constrict the vessels of the nasal mucosa, as a result of which swelling and hyperproduction of mucus by goblet cells are reduced. All drugs according to their duration of action can be divided into short-acting, medium-acting and long-acting. Short-acting derivatives include naphazoline and tetrizoline derivatives - their effect lasts no more than 4-6 hours, which requires their use 4 times. They negatively affect the ciliated epithelium of the nasal cavity. Medium-lasting decongestants (up to 8–10 hours) include xylometazoline derivatives. Oxymetazoline derivatives are long-acting vasoconstrictor drugs - 10-12 hours. Thanks to this, it is enough to use them 2-3 times a day. The long-term effect of these α2-adrenergic agonists is explained by their slow elimination from the nasal cavity due to a decrease in blood flow in the mucous membrane. The severity of the anti-edematous effect of all imidazoline derivatives is approximately the same. In 20 minutes. after their use, approximately 60% of their maximum effect develops, which manifests itself after 40 minutes. However, the duration of their action is very different: after 4 hours, the decongestant effect of indanazoline, naphazoline and tetrizoline is no longer present, but is retained by xylometazoline, oxymetazoline, and tramazoline. 8 hours after application to the mucous membrane, only oxymetazoline retains a pronounced effect [16]. The undoubted advantages of oxymetazoline are the absence of toxic effects on ciliated epithelial cells, which preserves mucociliary clearance [17,18]. All decongestants have class-specific undesirable effects: burning sensation, sneezing, congestion (reactive hyperemia), dry mucous membranes. The development of reactive hyperemia and dry mucosa can be avoided by using additional components in decongestants, such as menthol, camphor, and eucalyptol. These natural components not only have moisturizing and anti-inflammatory effects, but also contribute to a more uniform distribution of the main vasoconstrictor drug and are perfectly combined with it. An additional benefit is the anti-inflammatory effects of these substances. Thus, eucalyptol is a strong inhibitor of the production of cytokines such as TNF-α and interleukin-1, and thus reduces excess secretion of the mucous membranes of the respiratory tract, which enhances the effect of the main substance - oxymetazoline [19]. In addition, eucalyptol and camphor have antimicrobial and antifungal activity, in particular against Cl. perfringens and C. albicans [21]. As for the evidence base for the effectiveness of decongestants, Taverner D. et al. The meta-analysis included 7 randomized placebo-controlled studies assessing the effectiveness of oral and local decongestants in adults and children for ARVI (The Cochrane Library, MEDLINE, OLDMEDLINE, EMBASE). A statistically significant 6% reduction in nasal congestion was demonstrated after a single dose of decongestants compared to placebo. With repeated use of vasoconstrictors, the reduction in nasal congestion was reduced to 4%. Two studies demonstrated safety and few side effects. The authors concluded that a single dose provided relief of nasal breathing with continued effectiveness for 3–5 days. No studies have been conducted in children [9]. Previously, the same authors showed that 286 patients significantly - by 13% - noted a subjective decrease in symptoms of nasal congestion after using decongestants compared to placebo; with repeated use, the effect decreased slightly [10,11]. In the EPOS guidelines, the category of evidence for the use of decongestants for acute sinusitis is assessed as Ib(–), and the strength of recommendation is assessed as D (evidence category IV, the lowest). Therefore, topical corticosteroids are recommended as primary therapy (recommendation A). However, this cannot be excluded, and in the case of a purulent form, the simultaneous administration of decongestants is actively recommended [12]. According to the ARIA concept, decongestants are indicated for any form and severity of allergic rhinitis as symptomatic therapy, but not more than 10 days [5]. Today, Noxprey has appeared on the market - oxymetazoline in combination with eucalyptol, camphor, menthol in the form of a spray and characterized by all the advantages of its constituent substances: the duration of action of oxymetazoline along with a minimal toxic effect on the function of the ciliated epithelium, antimicrobial and immunostimulating properties of essential oils, preservation of natural moisture of the nasal mucosa. Noxprey is available in the form of a spray that evenly irrigates the nasal cavity and eliminates accidental overdose and can be used only 2 times a day. Currently, in the arsenal of general practitioners and otorhinolaryngologists there is a sufficient number of effective and safe pathogenetic drugs for the treatment of diseases of the upper respiratory tract. The main goals of such therapy are not only to alleviate the patient’s condition and shorten the duration of the disease, but also to prevent the development of complications. When choosing a drug intended for the symptomatic treatment of rhinitis, sinusitis, otitis, preference should be given to drugs with a good safety profile, long-term action and additional auxiliary effects.

How to reduce the risk of side effects
An important role is played by the choice of the form of release of the drug, with the most unsuccessful form being nasal drops. In the absence of a dispenser, simply infusing the drug with a pipette does not provide any way to control the amount of drug introduced into the nasal cavity, since most of it immediately enters the nasopharynx and is swallowed. This not only reduces the effectiveness of the drug, but also significantly increases the risk of systemic side effects. Studies have shown that xylometazoline metered spray with a pump is significantly more effective at improving nasal breathing than regular spray and drops.
The concentration of the solution used is equally important. Studies have shown that 0.1% and 0.05% solutions of xylometazoline have approximately the same vasoconstrictor effect, so it is preferable to start treatment with a lower concentration of the drug (intended for children) and only if its effectiveness is insufficient, switch to the standard adult form.
