“May all be happy, may all be healed, may all be at peace and may no one ever suffer."
Salmeterol Xinafoate is a selective, long acting beta-2 agonist used in the treatment of asthma and other forms of diffuse airways obstruction. Fluticasone Propionate is a corticosteroid with mainly glucocorticoid activity. Fluticasone Propionate is stated to exert a topical effect on the lungs without systematic effects at usual dose.
Salmeterol protects against symptoms, Fluticasone Propionate improves lung function and prevents exacerbations of the condition. This preparation can offer a more convenient regime for patients on concurrent β-agonist and inhaled corticosteroid therapy. The respective mechanisms of action of both drugs are discussed below:
Salmeterol: Salmeterol is a selective long-acting (12 hour) beta-2-adrenoceptor agonist with a long side chain which binds to the exo-site of the receptor.
Fluticasone Propionate: Fluticasone Propionate given by inhalation at recommended doses has a potent glucocorticoid anti-inflammatory action within the lungs, resulting in reduced symptoms and exacerbaions of asthma, without the adverse effects observed when corticosteroids are administered systemically.
This is indicated in the regular treatment of asthma where use of a combination product (long-acting β2-agonist and inhaled corticosteroid) is appropriate:
Inhalation Aerosol:
Inhalation Powder in Capsule (For Asthma):
Inhalation Powder in Capsule (For COPD): Salmeterol 50 µg & Fluticasone 250 µg twice daily (morning and evening, approximately 12 hours apart). Rinsing the mouth after each inhalation is advised.
Inhalation Powder in Maxhaler (For Asthma): This is a moulded plastic device containing a foil strip with 60 regularly placed blisters containing pre-dispensed inhalation powder. Patients should be made aware that Maxhaler must be used daily for optimum benefit, even when asymptomatic.
Adults and Adolescents (12 years and older)-
Children (4 years and older)-
Inhalation Powder in Maxhaler (For COPD):
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):
Instructions for Cleaning Inhaler: Clean your Inhaler at least once a week. Remove canister and rinse the plastic actuator and cap in warm water but do not put the metal canister into water. Dry the actuator and cap thoroughly and gently replace the metal canister into the actuator with a twisting motion. Put the cap on the mouthpiece.
This is contraindicated in patients with a history of hypersensitivity to any of the ingredients.
As this preparation contains Salmeterol and Fluticasone Propionate, the type and severity of adverse reactions associated with each of the compounds may be expected. There is no incidence of additional adverse events following concurrent administration of the two compounds. Adverse events, which have been associated with Salmeterol or Fluticasone Propionate, are given below.
Salmeterol: The pharmacological side effects of beta-2-agonist treatment, such as tremor, subjective palpitations and headache, have been reported, but tend to be transient and reduce with regular therapy. Cardiac arrhythmia (including atrial fibrillation, supraventricular tachycardia and extra systoles) may occur, usually in susceptible patients. There have been reports of arthralgia and hypersensitivity reactions, including rash, oedema and angioedema. There have been reports of oropharyngeal irritation. There have been rare reports of muscle cramps.
Fluticasone propionate: Hoarseness and candidiasis (thrush) of the mouth and throat can occur in some patients. Cutaneous hypersensitivity reactions have been reported. Rare cases of facial and oropharyngeal oedema have been reported. Both hoarseness and incidence of candidiasis may be relieved by gargling with water after use of Salmeterol/ Fluticasone Propionate Inhaler.
Consideration should be given to additional corticosteroid therapies, and to including administration of antibiotics if an infection is present. As with all inhaled medication containing corticosteroids, this preparation should be administered with caution in patients with active or quiescent pulmonary tuberculosis. This preparation should be administered with caution in patients with thyrotoxicosis.
Use in Special Populations
Orally inhaled corticosteroids may cause a reduction in growth velocity when administered to paediatric patients. The long-term effects of this reduction including the impact of final adult height are unknown.
Pregnancy & Lactation
Administration of drugs during pregnancy and lactation should only be considered if the expected benefit to the mother is greater than any possible risk to the foetus or child. There is insufficient experience of the use of Salmeterol Xinafoate and Fluticasone Propionate in human pregnancy and lactation. There are no data available for human breast milk.
