All about coronavirus 2019-nCoV for healthcare professionals

According to a survey conducted by ROSSTAT “Comprehensive monitoring of living conditions of the population 2018”, infectious diseases are the third reason for the independent use of medications as part of self-medication and self-prevention [1]. In such a situation, the pharmaceutical worker is actually the only qualified interlocutor of the buyer who is faced with a choice. Therefore, today, competent pharmaceutical consulting is gaining more and more importance.

The nasal mucosa is a typical “entry gate” for respiratory viruses, therefore, the temporary guidelines of the Russian Ministry of Health for the prevention, diagnosis and treatment of the new coronavirus infection (COVID-2019) dated March 27, 2020 indicate that for nonspecific prevention of coronavirus infection it is recommended to use drugs for topical use with barrier functions. Such drugs and medical devices form a physical barrier on the mucous membrane of the nasal cavity, preventing the adhesion of the virus. The compounds that form the barrier are gradually eliminated due to the work of the mucociliary apparatus. Theoretically, the protective layer will help slow the progression of the disease, since there will be fewer cells available to attack by viruses.

Directions for use and doses

Intranasally, as necessary, periodically, when visiting crowded places (to avoid airborne infection).

In adults and children (under adult supervision): 1 spray in each nasal passage 3-4 times a day (every 6-8 hours) - as a rule, the recommended dosage is sufficient for protection throughout the day.

It is recommended to repeat spraying the drug after each blowing of the nose to resume the formation of a protective film.

MEDICATIONS

The barrier function in medicinal products is performed by the substances that make up their ointment or gel base. In addition, intranasal medications also contain active ingredients: dioxotetrahydroxytetrahydronaphthalene (“Oksolin”, nasal ointment 0.25%), interferon alpha-2b (“Viferon”, ointment and gel for external and local use; “Infagel” gel for external and local use). However, the effectiveness of their use as declared antiviral agents does not have a sufficient scientific basis.

Fine powder of white or almost white color with a slight mint odor.

Use in children

The drug is not contraindicated in childhood and, after consultation with a doctor, can be used even in infants. In order for the medicine to have the expected effect, its administration into the nasal passages in children must be supervised by adults.

Action

The powder of cellulose and wild garlic extract from the dispenser enters the nasal mucosa and forms a transparent, gel-like, protective layer that does not interfere with breathing.
The gel-like layer is an effective barrier against viruses and bacteria, protecting the body from colds and ARVI. Due to its antiseptic properties, wild garlic extract inhibits the growth and neutralizes bacteria and viruses that enter the nasal mucosa with inhaled air.

Nasal spray, dosed Nazaval® PLUS is a barrier agent and does not have a systemic or local effect.

Use during pregnancy and breastfeeding

Nazaval® PLUS can be used during pregnancy and breastfeeding, since it does not have a systemic effect and does not contain preservatives.

Impact on the ability to drive vehicles and operate machinery

The use of the barrier agent Nazaval® PLUS does not affect the ability to drive vehicles and does not cause drowsiness.

MEDICAL DEVICES

"Nazaval PLUS"

“Nazaval PLUS” is a finely dispersed cellulose powder, which, when it enters the nasal cavity, binds to mucus and forms a gel-like layer on the mucous membrane that prevents viruses from entering the body. Due to wild garlic extract (allicin and ajoenes), the growth of bacteria and viruses is suppressed, and they are also neutralized [2].

The medical product “Nazaval PLUS” can be used in children and adults, as well as women during pregnancy and breastfeeding.

Emergency protection Seasonal protection
Before contact with a sick person, in crowded places, in public transport For daily protection against respiratory viruses all day long
1 injection into each nasal passage while inhaling, once (10-15 minutes before contact, visiting a public place, traveling) 1 injection into each nasal passage while inhaling 3-4 times a day (every 5-6 hours)

Natural peppermint extract included in Nazaval PLUS serves as an indicator of proper use. The appearance of a slight mint smell after injection indicates that the powder from the bottle has entered the nasal cavity.

Method of application:

Step 1. Before use, if necessary, hygienically clean the nasal cavity or blow your nose.

Step 2. Gently shake the bottle. When using for the first time, it is recommended to make 2 test injections into the air.

Step 3. Pinch one nasal passage with your finger, inhale the powder into the opposite nasal passage, pressing INTENSIVELY on the walls of the bottle. Repeat the same procedure on the other side.

It is recommended to reuse after each cleansing of the nasal cavity to restore the protective layer.

If it is necessary to use it together with other nasal medications, Nazaval PLUS should be used no earlier than 30 minutes after their use, having previously cleaned the nasal passages. It is not recommended to use Nazaval PLUS after using nasal ointments and oil-based nasal drops.

Also among buyers, the demand for medical products used to protect the nasal mucosa from aeroallergens has increased significantly, since the principle of action is the same.

pharmachologic effect

GCS for intranasal use. It has a pronounced anti-inflammatory and antiallergic effect. When used in therapeutic doses, it has virtually no resorptive effect. It does not have mineralocorticoid activity and is well tolerated during long-term treatment. The drug has an inhibitory effect on the release of mediators of the inflammatory response, increases the synthesis of anti-inflammatory proteins, reduces the number of mast cells and eosinophilic granulocytes. Budesonide reduces the release of toxic proteins from eosinophils, free radicals from macrophages and lymphokines from lymphocytes. It also reduces the binding of adhesion molecules to endothelial cells, thus reducing the flow of leukocytes to the site of allergic inflammation. Budesonide increases the number of β-adrenergic receptors in smooth muscle. The drug inhibits the activity of phospholipase 2A, which leads to inhibition of the synthesis of prostaglandins, leukotrienes and PAF, which induce an inflammatory response. Budesonide also inhibits histamine synthesis, which leads to a decrease in histamine levels in mast cells.

Tafen® nasal reduces the severity of symptoms in allergic rhinitis, suppresses the late and early phases of the allergic reaction and reduces inflammation in the upper respiratory tract. Improvement in condition is observed 2-3 days after the start of treatment.

Pharmacokinetics

Suction

After inhalation of 400 mcg of budesonide, Cmax in plasma is achieved within 0.7 hours and is 1 nmol/l.

Only about 20% of the intranasally administered dose enters the systemic circulation.

Distribution

Due to good distribution in tissues and binding to plasma proteins, Vd is 301 l.

Metabolism

Systemic bioavailability of budesonide is low because more than 90% of the absorbed drug is inactivated in the process of one-step metabolism in the liver. Glucocorticoid activity of metabolites does not exceed 1%.

Removal

Metabolites are excreted mainly in urine (70%) and feces. T1/2 is 2-3 hours.

Indications

– prevention and treatment of seasonal and year-round allergic rhinitis,

- non-allergic rhinitis,

- nasal polyps.

ICD-10 codes

Dosage regimen

At the beginning of therapy, adults and children over 6 years of age are prescribed 2 doses (50 mcg of budesonide) in each nostril 2 times a day. The usual maintenance dose is 1 dose in each nostril 2 times a day or 2 doses in each nostril 1 time a day, in the morning. The maintenance dose should be the lowest effective dose to relieve rhinitis symptoms.

The maximum single dose is 200 mcg (100 mcg in each nostril), the maximum daily dose is 400 mcg for no more than 3 months.

For full therapeutic effect, regular and correct use is required.

If a dose is missed, it should be taken as soon as possible, but not less than 1 hour before taking the next regular dose.

Side effect

From the respiratory system: irritation of the mucous membrane of the nose and throat, nosebleeds, cough, less often dry nasal mucosa, sneezing.

Dermatological reactions: dermatitis, urticaria, rash are noted.

Other: fatigue, dizziness.

In exceptional cases, when using nasal corticosteroids, perforation of the nasal septum, angioedema, loss of smell, tachycardia, and growth retardation were observed.

When using the drug, side effects develop very rarely and are transient.
