Open the CIPO recordAbstract From the Canadian patent
A melt spinnable carrier agent such as sugar is combined with a medicament then converted into fiber form by melt spinning with "cotton candy" fabricating equipment. The as-spun product is converted to compacted individual dosage units. For certain medicaments a binding agent is added to the carrier agent. Examples are presented for oral administration, topical application, systemic and nonsystemic, intravenous and intra-muscular infusion via multicameral containers. All applications utilize the extraordinarily rapid entry into solution upon contact with a solvent.
