Abstract
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 non-systemic, intravenous and intra-muscular infusion via multicameral containers. All applications utilize the extraordinarily rapid entry into solution upon contact with a solvent.

- 1. A spun fibrous pharmaceutical composition comprising a mass of spun fibers of a material capable of being spun into fibers that are readily water-soluble and a medicament distributed on or incorporated in said fibrous mass.
-
17. A pharmaceutical dosage unit comprising compacted spun fibers of a spinnable, readily water soluble material and an effective amount of a medicament.
- 18. A system for topical delivery of a medicament comprising a wafer containing a mass of fibers, and means for securing said wafer in contact with a dermal area to be treated, said mass of fibers, comprising a soluble fiber forming ingredient and a medicament where at least said fiber forming ingredient has been spun into fibers, and in said fiber form said ingredient has a solubility characteristic corresponding to that of spun sugar fibers in water.
- 25. A multicameral container for intravenous or intra muscular administration comprising a first compartment containing a pharmaceutically acceptable solvent, and a second compartment containing a spun fibrous pharmaceutical composition comprising a mass of spun fibers of a material capable of being spun into fibers that are readily water-soluble and a medicament distributed on or incorporated in said fibrous mass.
- 29. A spun fibrous pharmaceutical composition according to claim 29, wherein said material is methyl cellulose.
- 31. A method for preparing a pharmaceutical dosage unit for delivering a medicament, comprising producing a mass of medicament bearing spun fibers by melt spinning a composition containing said medicament.
- 36. A method for preparing a rapidly dissoluble medicinal dosage unit for administering medication comprising in combination the steps of combining a medicament with a melt spinnable compatible carrier agent to provide an intermediate product, and producing a mass of medicament bearing fibers by melt spinning said intermediate product.
- 45. A rapidly dissoluble spun fibrous medicinal dosage unit for administering medication orally, sublingually, or buccally, consisting essentially of a compacted mass of spun fibers of a carrier agent capable of being spun into fibers that are readily water-soluble which dissolve in the saliva of the mouth, said mass having an enclosed volume that is at least 30% less than the as-spun enclosed volume, said carrier agent being selected from the group consisting of sugars, sugar alcohols and mixtures thereof, and an effective amount of an orally, sublingually, or buccally effective medicament distributed within or coated on said spun carrier agent fibers.
