Patients who have difficulties with dispensing a pressurized inhaler can be used for inhalation volumetric chamber with SEREVENT Inhaler
For full therapeutic result , regular use of salmeterol in the treatment of airway obstruction caused by asthma and COPD. The onset of bronchodilation effective ( more than 15 % improvement of FE01 ) occurs 10-20 min after drug administration in patients with asthma . The maximum effect of treatment is achieved after administration of several doses of the drug . The bronchodilator effect of salmeterol lasts 12 hours. It is particularly preferred for the treatment of nocturnal asthma symptoms in COPD , as well as to effort provoked symptoms of asthma .
Patients should be instructed need to treat the symptoms of the disease should not take extra doses of the drug and to take fast-acting inhaled B2 - agonist.
Since the application of this class of drugs in high doses may be adverse effects , the dosage and frequency of administration of SEREVENT should only be increased on medical advice .
 
adults
Treatment of asthma and COPD ( chronic bronchitis and pulmonary emphysema ): Two inhalations (2 x 25 mCg salmeterol) twice daily.

4.3 . Contraindications
Hypersensitivity to any component of the product.
 
 
4.4 . Special warnings and precautions for use
Treatment of asthma should normally follow a pattern and course of disease symptoms should be evaluated clinically and by lung function tests.
SEREVENT should not be used in patients with significantly worsening or acutely progressive asthma.
Sudden and progressive deterioration in asthma is potentially life threatening . Bronchodilators should not be the sole or primary treatment for patients with severe and unstable asthma. Severe asthma requires constant medical supervision and assessment as death may occur . Patients with severe asthma have constant symptoms and frequent exacerbations , with limited breathing capacity. The value of peak expiratory flow ( PEF ) is below 60 % of the expected baseline values by more than 30 % variation and does not reach the normal values after administration of a bronchodilator . These patients require higher doses of inhaled corticosteroids (e.g., more than 1 mg per day, beclomethasone dipropionate) or oral corticosteroids . Symptomatic treatment with adjunctive SEREVENT may be combined with an optimized background corticosteroid therapy. Sudden worsening of symptoms of the disease require increased corticosteroid dosage which should be done urgently under medical supervision.
Increased use of bronchodilators , especially short-acting inhaled B2 - agonists indicates deterioration of asthma control . If the patient is ascertained that the treatment with short-acting bronchodilators is less effective, or if they need more inhalations than usual, it is necessary to pay attention to the physician. In these cases, patients should be re-evaluated and the doctor eventually increase the dose of anti-inflammatory drugs (eg higher doses of inhaled corticosteroids or a course of oral corticosteroids ) . Severe exacerbations of asthma must be treated in the normal way.
Treatment with twice daily SEREVENT replaces , short ( 4 hours) of inhaled bronchodilator (eg salbutamol), when more than one admission per day or oral bronchodilators (eg salbutamol, theophylline).
SEREVENT not replace treatment with oral and inhaled corticosteroids .
Treatment with its complement treatment with corticosteroids. The patient should be warned not to stop treatment with corticosteroids and not to reduce consumption dose without a doctor even if you feel better from the application of SEREVENT. If the patient is taking anti-inflammatory therapy , early treatment with salmeterol should be discussed and its initiation.
Because the action will occur more slowly ( 10-20 min ), SEREVENT should not be used in an acute asthma attack , wherein the appropriate application of short-acting bronchodilators onset within 5 minutes ( eg salbutamol ) . Patients should be advised to have such drugs.
You need to check the way in which the patient inhales the drug. To achieve optimal drug to the lungs to be synchronized breathing and injection salmeterol.
SEREVENT should be used with caution in patients with thyrotoxicosis , coronary insufficiency , arrhythmias and uncontrolled hypertension .
 
 
4.5 . Interactions
Should avoid the use of beta- receptor blockers ( both non-selective and selective ) in patients with obstructive airway disease , unless there is an overriding need for their application .
 
 
4.6 . Pregnancy and lactation
Studies in animals have shown some effects on the fetus , typical of B2 -agonists occur at doses greatly in excess of the therapeutic . Extensive studies of other B2 agonists showed no evidence of such effects in women receiving therapeutic doses.
Experience of the use of salmeterol during pregnancy is limited.
As with any drug use in pregnant women is justified only if the expected benefit of its use outweighs the potential risk to the fetus.
Plasma levels of salmeterol after inhalation at therapeutic doses is negligible , so it is assumed that the amount excreted in breast milk is relatively low . However, because the experience in the use of salmeterol in nursing mothers is small , it should not be used by them only when the expected benefit outweighs the potential risk to the fetus.
Animal studies confirm that the amount of salmeterol, separation breast milk is negligible .
 
 
4.7 . Effects on ability to drive and use machines
No data available.
 
 
4.8 . Undesirable effects
Adverse reactions are presented by system frequency.
Common and uncommon events were generally determined from clinical trial data . Placebo responses are not taken into account. Very rare adverse events in a large part is determined by the post-marketing data .
The following adverse reactions have been observed at the standard dose OT_50_mcg twice daily. The frequency at higher doses of 100 mcg twice daily were also taken
account, where appropriate.
 
Disorders Immune system
Hypersensitivity reactions :
Uncommon : Rash .
Very rare: edema and angioedema
 Disorders of the nervous system
Common: Tremor and headache.
Side effects such as tremor and headache observed during treatment with B2
agonists are transient and reduce with regular therapy. Tremor was observed more frequently when administered at higher doses of 50 mcg twice daily.
Disorders of the cardiovascular system part
Common: Palpitations .
Side effects such as subjective palpitations that occur during treatment with B2
agonists are transient and reduce with regular therapy.
Uncommon : tachycardia.
Tachycardia occurs more commonly when administered at higher doses of 50 mcg twice daily.
Very rare : Cardiac arrhythmias (including atrial fibrillation , supraventricular tachycardia and extrasystoles ) .
Disorders of respiratory , thoracic and mediastinal disorders
Very rare: Oropharyngeal irritation and paradoxical bronchospasm .
As in treatment with other inhaled medicines may appear paradoxical bronchospasm , which is manifested by an increase in wheezing immediately after dosing of the drug. It should be treated immediately with a fast-acting inhaled bronchodilator . Inhaler treatment with SEREVENT should be discontinued immediately and the patient to undergo a re-evaluation , and, if necessary, be an alternative treatment .
Violations by the locomotor system
Common: Muscle spasms
Very rare: Arthralgia .
 
 
4.9 . overdose
Symptoms of salmeterol overdose are tremor, headache and tachycardia. treatment
The preferred antidote for overdosage with salmetereol is a cardioselective beta blocker. Cardio -selective beta- blockers should be used with caution in patients with a history of bronchospasm.
 
5 . Pharmacological
Pharmacotherapeutic group : Adrenergics and other anti-asthmatics
ATC code : R03AC12
 
 
5.1. Pharmacodynamic properties
Mechanism of action
SEREVENT selective B2 -adrenoceptor agonist with a long 12 hours) operation , with a long side chain , which is associated with the outer surface of the receptor.
These pharmacological properties of salmeterol permit more effective protection against histamine - induced bronchoconstriction and provide long lasting ( at least 12 hour ) bronchodilation compared to kratkotraynodeystvashtite B2 - agonists. In vitro studies show that salmeterol is a potent long-acting inhibitor of mast cell mediators , such as histamine , leukotrienes and prostaglandin D2, released from human lung .
In humans, salmeterol inhibits the early and late phase response to inhaled allergens. Late phase persists more than 30 hours after taking a dose of spray when the bronchodilator effect has already been terminated . Single dose salmeterol attenuates bronchial hyper . These properties indicate that there is an additional non-bronchodilator SEREVENT activity, but the clinical significance is not yet clear . Its mechanism of action is different from the anti-inflammatory effect of corticosteroids , which should not be suspended or reduced , when the prescribed SEREVENT.
SEREVENT been studied in the treatment of conditions associated with COPD and the results of treatment have shown that its use improves lung function and quality of life of the patient. As p2 - agonist salmeterol acts on the reversible component of the disease. In vitro salmeterol increased the mucociliary clearance of human bronchial epithelial cells. Also reduces the toxic effect of the acid of the toxin of Pseudomonas to epithelial bronchial mucosa in patients with cystic fibrosis.
 
 
5.2 . pharmacokinetics
Salmeterol acts locally in the lung, which gives grounds to assume that plasma levels do not determine the therapeutic effect . There are few data on the pharmacokinetics of salmeterol because of the technical difficulties associated with the determination of the drug in plasma, as after inhalation of the drug plasma concentration is very low (approximately 200 pg / ml or less) .
After inhalation of salmeterol xinafoate, in the bloodstream can be found hydroxynaphtoic acid, reaching equilibrium concentrations of about 100 ng / ml. These concentrations were 1000 -fold lower than the levels observed in the toxicity studies .
These concentrations after prolonged use (more than 12 months) in patients with pulmonary obstruction disease do not cause change.
 
 
5.3 . Preclinical safety data
In reproduction studies in animals at very high doses , the fetus were observed some effects typical of B2 - agonist.
Salmeterol xinafoate did not show genotoxicity, which is confirmed by in vivo or in vitro studies with cell prokaryotic or eukaryotic systems in rats .
Long-term studies with salmeterol xinafoate indicate the occurrence of benign tumors of the smooth muscle of rats and mezovariuma uterus of mice. Literature and our pharmacological studies confirm that these effects are very specific for this type and occur in clinical use .
