איזו תרופה ניתן לשקול בחולים עם אסתמה אאוזינופילית מעל גיל 12
Mepolizumab- step 6
What are the medications for the 6 step approch of asthma menegment?
- SABA
- low dose ICS
- Medium dose ICS or Low dose ICS + LABA/LATRA
- medium dose ICS + LABA /LTRA / theophylline (for age > 4 )
- High dose ICS+ LABA /LTRA / theophylline age > 6 - consider omalizumab if allergic
- High dose ICS+ LABA /LTRA / theophylline + OCS + age > 12 - consider mepolizumab if eosinophils or omalizumab
from Step 4 only 0-4 could change LABA in LTRA
