چکیده

2014 Long-acting β-agonists (LABAs) are the standard of care for chronic obstructive pulmonary disease (COPD) patients with advanced disease, those with mild to moderate disease and frequent exacerbations or those with significant dyspnea. Currently available LABAs include salmeterol, formoterol, indacaterol, vilanterol and olodaterol. The bronchodilatory effect of LABAs is mediated via the binding and ligation of the β2–adrenergic receptor and the lipophilic nature of the LABA compound accounts for their long duration of action. LABAs are available as hand held devices, either as a single agent or combined with a corticosteroid. Proper inhaler technique is necessary for adequate drug delivery but is often difficult to achieve in older patients with significant impairment in cognition, dexterity or ability to generate adequate inspiratory flow rates. Arformoterol, which is an (R,R) enantiomer of formoterol, is available as a nebulized solution and is clinically equivalent to formoterol or salmeterol. Arformoterol as a nebulized solution provides an alternative to device-based LABAs in select patients.

pharmacotherapy of chronic Obstructive pulmonary Disease: Focus on Arformoterol Tartrate

Arformoterol tartrate is a newly developed long-acting ssβ2-agonist with both acute and prolonged bronchodilator effects. It is formed of 2 isomers (R,R/R,R) which distinguishes it from the more commonly used racemic formoterol (R,R/S,S). The active isomer is the (R,R) and in vitro arformoterol may have more potent anti-inflammatory effects than formoterol. It can only be given by a nebulizer. ...

Role of arformoterol in the management of COPD

Formoterol is a beta2-agonist that has both short and long acting bronchodilator effects. Beta2-agonists used as bronchodilators have been synthesized as racemates that comprise (R,R) and (S,S)-enantiomers. Compounds that are beta2-selective derive their bronchodilator effect from an interaction between the (R,R)-enantiomer and the beta2-adrenoceptor. Arformoterol is the (R,R)-enantiomer and is...

Hospital readmissions following initiation of nebulized arformoterol tartrate or nebulized short-acting beta-agonists among inpatients treated for COPD

BACKGROUND Inpatient admissions for chronic obstructive pulmonary disease (COPD) represent a significant economic burden, accounting for over half of direct medical costs. Reducing 30-day readmissions could save health care resources while improving patient care. Recently, the Patient Protection and Affordable Care Act authorized reduced Medicare payments to hospitals with excess readmissions f...

The influence of breathing pattern during nebulization on the delivery of arformoterol using a breath simulator.

BACKGROUND Patients with obstructive airway conditions, including chronic obstructive pulmonary disease (COPD), use nebulizers for drug delivery. Tidal breathing patterns employed by patients during nebulized drug delivery may vary. It is unclear whether different breathing patterns affect the emitted quantity of nebulized drug. This in vitro study evaluated whether different tidal breathing pa...

Long-term health-related quality-of-life and symptom response profiles with arformoterol in COPD: results from a 52-week trial

Background Symptom severity is the largest factor in determining subjective health in COPD. Symptoms (eg, chronic cough, dyspnea) are associated with decreased health-related quality of life (HRQoL). We evaluated the impact of arformoterol on HRQoL in COPD patients, measured by St George's Respiratory Questionnaire (SGRQ). Post hoc growth mixture model (GMM) analysis examined symptom response p...
