Main information about Ventolin
Ventolin is an irreplaceable product in the treatment of the bronchial asthma or reversible diseases of the respiratory system. It contains an active ingredient Salbutamol.
Ventolin is produced in the form of a metered aerosol for the inhalations. During the inhalations, the active ingredients penetrate into the walls of the respiratory tracts and cause a relaxation of the smooth muscles. Due to this, a dilation of bronchi and respiratory tracts happens during bronchospasm. The symptoms of asphyxia, shortness of breathing disappear, and the work of the respiratory system becomes normal.
About 10-20% of the dose of Ventolin penetrates in the blood plasma. After the penetration into the blood, Ventolin inhibits the release of leukotrienes, prostaglandins and other biologically active ingredients which take part in the inflammatory reactions and bronchospasm from the mast cells of histamine. Ventolin reduces bronchospasms not only during chronic inflammatory obstruction of the airways but also during bronchial asthma of the allergic origin.
In case of the prolonged use of Ventolin, the vital volume of the lungs, and a nutrition of the blood with oxygen are increased. Ventolin selectively acts to beta2adrenoceptors and does not influence on beta1-adrenoceptors of the heart. Therefore, using this drug, the side effects seldom appear in the cardiovascular system.
Use and dose of Ventolin
To reduce bronchospasms, Ventolin is often used in the form of aerosol for the inhalations. Aerosol has 300 doses in the bottle. Every dose (one puff) contains 100 mcg of Salbutamol. To remove an attack of the bronchospasm, Ventolin is used up to 4 times per day, 100-200 mcg (1-2 inhalations).
Ventolin isnotusedmorethan 4 timesperday. The overdose may lead to a sudden obstruction of the respiratory tracts and bronchospasm. To prevent bronchospasm related to the effect to allergen or during physical activity, it is recommended to use Ventolin 200 mcg (2 inhalations) 15-20 minutes before the interaction with an offending agent.
Recommendations for the use
- If you feel a reduced efficiency of Ventolin and a need in having the inhalations more than 4 times per day during the prolonged maintaining therapy of the bronchial asthma, go to a doctor. Perhaps, a sensitivity to the action of Salbutamol is decreased, and a medicine should be replaced
- Using Ventolin during pregnancy, there is a chance of the formation of pathologies in fetus. Therefore this medicine is prescribed during pregnancy only in an emergency, when life of a mother is at threat because of the severe bronchospasms
- Take Ventolin carefully, if you have the following chronic diseases: ischemic heart disease, heart failure, cardiac defect, arrhythmia, and hypertension
About 60% of Salbutamol is left on the mucous membrane of the mouth cavity, and therefore some side effects are possible during the use of Ventolin: dry mouth, irritation of the mucousmembraneofthe oral cavity and pharynx.
Severer side effects happen seldom: tremor, headache, and tachycardia. If side effects bother you during the use of Ventolin, consult a physician.
