RESUMEN
OBJECTIVE: The aim of the present study was to determine the cost-utility of single inhaler combination inhaled corticosteroid and a long-acting ß2-agonist (ICS/LABAs) as both maintenance and reliever (SMART) compared with a step-up maintenance treatment with a fixed medium to high dose of ICS combined with LABA and a short-acting ß2-agonist (SABA) as reliever (ICS-LABA maintenance plus SABA) among patients aged 12 years or more with poorly controlled asthma in Colombia. METHODS: A Markov-type model was developed to estimate the costs and health outcomes of a simulated cohort of patients aged 12 years or more with uncontrolled asthma treated for 12 months. The main effectiveness data were obtained from a recent meta-analysis. The main outcome was the variable ''quality-adjusted life-years'' (QALYs). RESULTS: The base-case analysis showed that the budesonide/formoterol (BUD/FORM) SMART strategy was associated with lower overall treatment costs (US $3,062.37 vs. $4,462.02 average cost per patient over 12 months) and the greatest gain in QALYs (0.8511 vs. 0.8258 QALYs on average per patient over 12 months) compared with ICS-LABA maintenance plus SABA at step 4, thus leading to dominance. CONCLUSIONS: In patients aged 12 years or more with uncontrolled asthma at GINA step 3 or 4, the BUD/FORM SMART strategy at either step 3 or 4 is cost-effective compared with the ICS-LABA maintenance plus SABA at step 4 strategy, because it shows a greater gain in QALYs at lower total treatment costs.
RESUMEN
Los broncodilatadores beta 2 agonistas (B2A), forman parte muy importante en la farmacoterapia del asma bronquial, enfermedad que avanza en el mundo, de manera epidémica. Los B2A, son prescritos a millones de personas en el mundo, por consiguiente; los aspectos de seguridad son de interés público. Los broncodilatadores B2A de acción corta (Short-Acting B2 Agonists o SABA) como salbutamol inhalatorio, según las evidencias actuales, confirman su seguridad, en su uso como fármaco de rescate o a demanda. Los broncodilatadores B2A de acción prolongada (Long-Acting B2 Agonists o LABA), se utilizan asociados a corticoides inhalatorios, como medicamentos controladores de exacerbaciones de accesos asmáticos, por razones de seguridad los LABAs se usan asociados a corticoides inhalatorios...
Beta 2 agonist bronchodilators (B2A) are very important part in the pharmaco therapy of bronchial asthma, a disease that progresses in the world in an epidemic way. The B2A are prescribed to millions of people around the world, there fore the safety aspects is of public interest. Short-Acting B2 Agonists (SABAs), such as albuterol inhaler, according to current evidence, have confirmed their safety when used as a quick-relief or rescue medication. The long-acting B2 agonists (LABAs) are used associated with inhaled corticosteroids as controller drugs for asthma exacerbations, for safety reasons LABAs are used associated with inhaled corticoid...
