Dry powder inhalers: Particle size and patient-satisfaction
Inhalational route is the cornerstone for drug delivery in asthma. Dry powder inhalers efficiently deliver drug particles to lungs depending on patients' breath actuation and without using propellants. Drug delivery in lungs is dependent primarily on particle size distribution of the formulatio...
