[Long-term tolerability of formoterol in chronic obstructive bronchopathies].
Formoterol aerosol, a long-acting new beta 2-mimetic was administered over a year at a dose of 12 micrograms twice daily, to 62 chronic obstructive bronchitics of mean age 66 +/- 6 years and of whom the basal VEMS was at 12,801 +/- 0.59. Clinical tolerance of the product was good with undesirable effects in 13 patients, the most frequent being shaking. No untoward effect was seen on systolic or diastolic arterial pressure, or the heart rate over successive visits at 1, 3, 6, 9 months and one year. Electrocardiographic surveillance found in only four patients electrical abnormalities that may be due to Formoterol, these were patients without previous cardiac problems but of advanced mean age. Functionally, a significant improvement of basal VEMS was noticed from the 6th month. The VEMS improved significantly after administration of 12 micrograms on successive visits, without tachyphylactic signs. Well tolerated, with functional benefits, Formoterol is a promising product amongst the long-acting beta 2-mimetics. Its usefulness and limitations in the basic treatment of these chronic bronchopathies remains to be defined.
