৳ 200.00
Indications
Inhaled Seravent exerts a significant bronchodilating effect within 10 to 20 minutes of single-dose administration with asthma and this effect lasts for up to 12 hours or more.
Seravent has a beneficial effect on airway mucociliary clearance that will reduce the incidence of respiratory tract infections.
Seravent produces a significant protective effect against Exercise Induced Asthma (EIA) for up to 9 to 12 hours in both adolescents and adults.
Seravent improves the overnight PEFR (Peak Expiratory Flow Rate) and controls the symptoms of the patients with nocturnal asthma. The use of Seravent avoids exposure of children to theophylline or high-dose corticosteroid, with their attendants risks.
Addition of Seravent to inhaled corticosteroid therapy is significantly more effective in terms of an improvement in lung function, symptom control and a reduction in the use of rescue bronchodilator therapy (use of short acting beta2-agonist).
Addition of Seravent to inhaled corticosteroid therapy also significantly reduces the use of inhaled corticosteroids

Pharmacology
Salmeterol stimulates intracellular adenyl cyclase, the enzyme that catalyses the conversion of ATP to cyclic-3',5'-adenosine monophosphate (cAMP) resulting in relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from mast cells.

Administration
Using an Inhaler seems simple, but most patients do not know how to use it in the right way. If the Inhaler is used in the wrong way, less medicine can reach the lungs. Correct and regular use of the Inhaler will prevent or lessen the severity of asthma attacks.
Following simple steps can help to use Inhaler effectively (According to "National Asthma Guidelines for Medical Practitioners" published by Asthma Association):
Following simple steps can help to use Inhaler effectively (According to "National Asthma Guidelines for Medical Practitioners" published by Asthma Association):
- Take off the cap.
- Shake the inhaler (at least six times) vigorously before each use.
- If the inhaler is new or if it has not been used for a week or more, shake it well and release one puff into the air to make sure that it works.
- Breathe out as full as comfortably possible & hold the inhaler upright.
- Place the actuator into mouth between the teeth and close lips around the mouthpiece.
- While breathing deeply and slowly through the mouth, press down firmly add fully on the canister to release medicine.
- Remove the inhaler from mouth. Continue holding breath for at least for 10 seconds or as long as it is comfortable.
- If doctor has prescribed more than one inhalation per treatment, wait 1 minute between puffs (inhalations). Shake the inhaler well and repeat steps 4 to 7.
- After use, replace the cap on the mouthpiece. After each treatment, rinse mouth with water.
- Check your technique in front of a mirror from time to time, if you see a white mist during the inhalation, you may not have closed your lips properly around mouthpiece, or you may not be breathing in as you press the can. This indicates failure of technique. If this happens, repeat the procedure from step 4 carefully.
