CLINICAL ASPECTS IV.1 Introduction Product profile: 4.1 Therapeutic indications Salmeterol and Fluticasone propionate pressurised inhalation suspension is indicated in the regular treatment of asthma where use of a combination product (long-acting beta-2-agonist and inhaled corticosteroid) is appropriate: - patients not adequately controlled with inhaled corticosteroids and 'as needed' inhaled short acting beta-2-agonist or - patients already adequately controlled on both inhaled corticosteroids and long-acting beta- 2-agonist. 4.2 Posology and method of administration Recommended Doses: Adults and adolescents 12 years and older: • Two inhalations of 25 micrograms salmeterol and 125 micrograms fluticasone propionate twice daily. Or • Two inhalations of 25 micrograms salmeterol and 250 micrograms fluticasone propionate twice daily. Pharmacodynamics (extracted from the Clinical overview) Fluticasone propionate Fluticasone propionate is a corticosteroid designed for topical use. It is not suitable for oral administration as it is subject to almost 100% first-pass inactivation in the liver. It has a high affinity for the glucocorticoid receptor with negligible binding to the mineralocorticoid, estrogen, progesterone, and aldosterone receptors. Fluticasone propionate potentially has the effects anticipated for any corticosteroid: increasing protein catabolism, having anti-inflammatory actions, immunosuppressant action, being diabetogenic and impairing bone metabolism, thus promoting osteoporosis. Immunosuppressant activity was demonstrated by a decline in thymus weight in dog and rat studies. In common with other intranasal and inhaled steroids, fluticasone propionate has anti-inflammatory and immunosuppressant activity. Salmeterol Salmeterol is a selective long-acting (12 hour) beta-2-adrenoceptor agonist. Salmeterol xinafoate has pharmacologic actions similar to those of other selective β2- adrenergic receptor agonists (e.g., albuterol). Salmeterol stimulates β2-adrenergic receptors and apparently has little or no effect on α-, β1-, or β3-adrenergic receptors. The principal effect following oral inhalation of salmeterol and other β2-adrenergic agonists is bronchodilation resulting from relaxation of smooth muscles of the bronchial tree. Salmeterol 4/26 produces a longer duration of bronchodilation, lasting for at least 12 hours, than recommended doses of conventional short-acting beta-2-agonists. Salmeterol, like other β2-adrenergic agonists, can produce changes in heart rate and blood pressure (dose-related increases in heart rate of 3–16 beats/minute). At higher dosages, salmeterol administration has been associated with prolongation of the QTc interval. Administration of salmeterol and other β-adrenergic agonists may cause dose-related increases in blood glucose and/or decreases in serum potassium concentrations. Pharmacokinetics (extracted from the Clinical Overview) Fluticasone propionate Systemic absorption occurs mainly through the lungs and is initially rapid followed by a prolonged phase. The remainder of the inhaled dose may be swallowed but contributes minimally to systemic exposure due to the low aqueous solubility and pre-systemic metabolism, resulting in oral availability of less than 1%. There is a linear increase in systemic exposure with increasing inhaled dose. The disposition of fluticasone propionate is characterized by high plasma clearance (1150 ml/min), a large volume of distribution at steady-state (approximately 300 L) and a terminal half-life of approximately 8 hours. Plasma protein binding is 91%. Fluticasone propionate is cleared very rapidly from the systemic circulation. The main pathway is metabolism to an inactive carboxylic acid metabolite, by the cytochrome P450 enzyme CYP3A4. Other unidentified metabolites are also found in the faeces. The renal clearance of fluticasone propionate is negligible. Less than 5% of the dose is excreted in urine, mainly as metabolites. The main part of the dose is excreted in the faeces as metabolites and unchanged drug. Salmeterol Limited data have been published on the pharmacokinetics of salmeterol. Moreover, there is no data on the extent to which inhaled salmeterol undergoes first-pass metabolism. Larger inhaled doses give approximately proportionally increased blood concentrations. Plasma salmeterol concentrations of 0.1 to 0.2 and 1 to 2 mcg/L have been attained in healthy volunteers about 5 to 15 minutes after inhalation of a single dose of 50 and 400 mcg, respectively. In patients who inhaled salmeterol 50 mcg twice daily for 10 months, a second peak concentration of 0.07 to 0.2 mcg/L occurred 45 to 90 minutes
