Ventolin is a selective beta-2-adrenergic receptor agonist. In therapeutic doses, it affects the β2-adrenoreceptors of the bronchial muscles. Ventolin® has a short duration of action (from 4 to 6 hours) and a rapid onset of action (about 5 minutes from the moment of application).
Indications for use
As part of complex therapy:
- for the relief and prevention of the development of bronchospasm in patients with reversible airway obstruction (asthma, chronic bronchitis, emphysema)
- to relieve the symptoms of a bronchial asthma attack or to prevent them before contact with a known trigger (allergen).
Bronchodilators should not be the only or main component of the treatment of bronchial asthma. If the asthma patient does not respond to salbutamol therapy, it is recommended to use inhaled corticosteroids to achieve and maintain symptom control.
Insufficient response to salbutamol therapy may be a signal for urgent medical intervention/therapy.
Method of administration and dosage
Ventolin in the form of an aerosol is used only for inhalation by inhaling the aerosol through the mouth.
The duration of action of the drug Ventolin in most patients is 4-6 hours.
Patients who have difficulties with the coordination of inhalation and release of the drug from the inhaler can take Ventolin in the form of a spacer.
Use of the inhaler
The effect of the drug may be weakened if the inhaler is cold. When cooling the can, it is recommended to take it out of the plastic case and warm it with your hands for a few minutes. The can cannot be disassembled, pierced and thrown into the fire, even if it is empty.
- Remove the protective cap from the mouthpiece of the inhaler. Check the inside and outside of the inhaler, including the mouthpiece, for cleanliness and dryness, as well as for the presence of loose parts of the device.
- Shake the inhaler vigorously to evenly mix the contents of the inhaler, as well as to remove all loose parts from the surface of the device.
- Place the inhaler vertically between the thumb and index finger, placing the thumb on the base, below the mouthpiece.
- Take a deep (as far as possible) exhale. Then place the mouthpiece between your teeth (without biting it) and tightly wrap your lips around it.
- Take a deep breath through your mouth. While continuing to take a deep breath, press on the top of the inhaler.
- Hold your breath, remove the inhaler from your mouth and remove your index finger from the top of the inhaler. Continue to hold your breath as much as possible.
- If it is necessary to continue the inhalation, you should wait for about half a minute, holding the inhaler vertically, and then repeat the steps from the 2nd to the 6th.
- After inhalation, carefully put a dust cap on the mouthpiece.
