General
For dosing below, adult is age 12 or older
Preparation
Triamcinolone (Azmacort)
Dose per puff: 100 mcg/puff
Low dose
Adult: 3-4 puffs twice daily ($140/month)
Preparation
Beclomethasone Dipropionate (QVAR)
Qvar Redihaler HFA (breath-actuated MDI) will replace the older Qvar
Inhaler
Ostensibly this patent extending change is so patients need not coordinate breath to actuation
Dose per puff: 40 mcg/puff or 80 mcg/puff
Cost: QVAR 80 is $83, QVAR 40 is 66$ (100 puffs each)
Gene
ral
QVAR 80 is same cost of 40 and can use 1/2 puffs
Small particles allow for using without spacer

Child: 160 mcg/day (e.g. 40 mcg, 2 puff bid)
Preparation
Fluticasone propionate (Flovent HFA, ArmonAir)
May have more systemic absorption than other agents
