Recebido: 31.10.2011- Aceito para publicação: 20.04.2012 RESUMO Bromidrato de fenoterol é um agente agonista adrenérgico β2-seletivo utilizado para tratamento de asma e doenças pulmonares crônicas obstrutivas. A metodologia analítica por cromatografia líquida de alta eficiência (CLAE) foi desenvolvida e validada para a determinação quantitativa de bromidrato de fenoterol. A condição analítica empregada incluiu coluna em fase reversa C18 (150 mm × 3,9 mm d.i., 5 µm) Thermo®, fase móvel composta de mistura de acetonitrila e água (30:70, v/v) com 0,1% de trietilamina e pH ajustado para 5,0 com ácido fórmico, vazão de 1,0 mL.min-1 e detecção em UV a 276 nm. A faixa de linearidade foi de 0,025 a 0,15 mg.mL-1; a curva analítica mostrou coeficiente de correlação > 0,999. O limite de detecção (LD) foi de 0,003 mg.mL-1 e o limite de quantificação de 0,012 mg.mL-1.

    The study listed may include approved and non-approved uses, formulations or treatment regimens. The results reported in any single study may not reflect the overall results obtained on studies of a product. Before prescribing any product mentioned in this Register, healthcare professionals should consult prescribing information for the product approved in their country. Study No.: SAM 30020 Title: Efficacy and tolerability of the salmeterol/fluticasone 50/100 mcg combination Diskus, inhaled once daily in the evening, in comparison to the p.r.n. inhalation from the reproterol/sodium cromoglycate 0.5/ 1 mg combination MDI, as initial therapy for patients with mild asthma – a multicentre, randomised, open, parallel trial Rationale: The reproterol/sodium cromoglycate 0.5/ 1 mg combination is still widely used for the treatment of mild asthmatics. Usually, patients inhale the combination product from an MDI, and they adjust the dosage according to their asthma symptoms. Anti-inflammatory medication with an inhaled corticosteroid such as fluticasone is an alternative therapeutic option, and long-acting beta agonists can be used as bronchodilatory treatment. The study aimed to investigate whether the efficacy of the salmeterol/fluticasone 50/100-mcg combination (SFC), inhaled from the Diskus once daily in the evening, is superior to that of the PRN inhalation of the reproterol/sodium cromoglycate 0.5/ 1 mg combination (RS) from the metered dose inhaler. Phase: IV Study Period: 13 June 2002 to 27 June 2003 Study Design: This randomised, prospective, open, parallel group study had a total duration of ten weeks. There were two study periods: a run-in period of two weeks, and a treatment period of 8 weeks.

  • Short-Acting Inhaled B2-Agonists: Why, Whom, What, How?
    REVIEW Andrzej Emeryk1, Justyna Emeryk-Maksymiuk2 1Department of Pediatric Pulmonology and Rheumatology Medical University in Lublin, Poland 2Chair of Internal Medicine and Department of Internal Medicine in Nursing Medical University in Lublin, Poland Short-acting inhaled b2-agonists: why, whom, what, how? Abstract We showed the present data about the efficacy and safety of inhaled short-acting b2-agonists (SABA), such as salbutamol and fenoterol, in the management of obstructive diseases in children and adults. Our work discusses major mechanisms of action, clinical effects, possible side effects and indications of inhaled SABA. We presented current recommendations for the position of SABA in the therapy of obstructive diseases in children and adults, particularly in asthma and chronic obstructive pulmonary disease. Key words: short-acting b2-agonist, salbutamol, fenoterol, inhalation, nebulization, asthma, COPD Adv Respir Med. 2020; 88: 443–449 Introduction after administration of inhaled salbutamol, but the duration of action does not exceed 4–6 hours Short-acting b2-agonists (SABA) stimulate (Figure 1) [8]. b2-adrenergic receptor (b2-AR).
