Inhaled Drug Development

Inhalation is the most effective route of drug administration for treating diseases of the respiratory tract. This route ensures that drugs are delivered directly to their site of action where they exert the required local effect.  The three main inhalation approaches include the use of metered dose inhalers (MDIs), dry powder inhalers (DPIs) and nebulisers.

CPES offers inhaled formulation development services for DPI and Nebulised formulations:
