Dry powder inhalable formulations
Stable dry powder formulations engineered for pulmonary delivery with controlled particle morphology and aerodynamic size for deep lung uptake, intended as needle-free alternatives to injectables.
Sublingual wafers and buccal dissolvable formulations
Powder-processed wafers and tablets formulated to dissolve under the tongue or buccal mucosa to enable direct systemic absorption and reduce first-pass hepatic metabolism.
Nasal powder formulations
Powder formulations optimized for nasal mucosa delivery to support assisted delivery for children, elderly or patients with compromised lung capacity.
Topical powder formulations
Formulations designed for topical application to promote rapid local absorption or treat surface wounds and lacerations.
Device-compatible powder product prototypes
Pre-formulation and prototype powders tailored for compatibility with single-dose DPIs, multi-dose blister DPIs and pressurized metered-dose inhalers to ensure consistent metering and dispersibility.
