[Effect of immunomodulator AM3 on the exacerbations in patients with chronic bronchitis: a systematic review of controlled trials].
Analyze the effect of AM3, an oral immunomodulator, on the exacerbations and on the use of antibiotics in patients with chronic obstructive pulmonary disease (COPD). ⋯ The results of this systematic review show that AM3 has a clinical effect in the prevention of exacerbations of COPD patients because reduces significantly their number. This could be related to a slowing in the progression of the deterioration in the respiratory function with a potential impact on the quality of life of the patients. Furthermore, these data imply a positive therapeutic result and a possible decline in development of bacterial resistances secondary to the frequent and indiscriminate use of antibiotics in these patients.
