Maryland Rep. Kweisi Mfume and Sen. Angela Alsobrooks are advancing legislation designed to bring down the soaring cost of inhalers, nebulizers and other essential respiratory treatments. Their proposal would cap monthly expenses for insured and uninsured patients alike, expanding Medicare coverage and easing the financial strain on families managing asthma. The lawmakers say the measure is urgently needed as hospitalizations and racial disparities in respiratory illness continue to climb.
