A high dose rapidly dispersing three-dimensionally printed dosage form comprising a high dose of water soluble drug in a porous matrix that disperses in water within a period of less than about 15 seconds is disclosed. Also disclosed are methods of preparing the dosage form and of treating a condition, disease or disorder that is therapeutically responsive to the drug.

Rapid disperse dosage form

A taste-masked rapidly dispersible dosage form of topiramate is provided. Wax coated particles of topiramate are included within a porous bound matrix. The topiramate retains its taste-masked form after dispersion in the mouth of a subject even though the particles are not coated with a polymeric material. The dosage form disperses in saliva or water in less than 2 min even though it has a high content of wax. It can be used to treat diseases or disorders that are therapeutically responsive to topiramate or a derivative thereof.

Rapidly dispersible dosage form of topiramate

A high dose orodispersible dosage form of oxcarbazepine is provided. Drug-containing particles of oxcarbazepine are included within a porous bound matrix. The dosage form disperses in saliva or water in less than 15 sec and it has sufficient hardness to withstand handling and storage. It can be used to treat diseases or disorders that are therapeutically responsive to oxcarbazepine or a derivative thereof.

Rapidly dispersible dosage form of oxcarbazepine

The present invention is directed to pharmaceutical compositions that allow for once-daily or alternate day dosage forms of topiramate. The proposed delayed/extended release single dosage form is equivalent to the immediate-release multiple dose daily regimen, and upon administration, provides steady state blood levels of topiramate. Formulations with increased bioavailability and improved pharmacokinetics are disclosed. A once-a-day administration of topiramate is advantageous over the multiple dose regimen both in terms of patient compliance and reduced adverse events, thus providing better treatment of the conditions for which the topiramate is indicated.

Topiramate compositions and methods of enhancing its bioavailability

A high dose rapidly dispersing three-dimensionally printed dosage form comprising a high dose of levetiracetam in a porous matrix that disperses in water within a period of less than about 15 seconds is disclosed. Also disclosed are methods of preparing the dosage form and of treating a condition, disease or disorder that is therapeutically responsive to levetiracetam.

Rapid disperse dosage form containing levetiracetam

A high dose rapidly dispersing three-dimensionally printed dosage form comprising a high dose of levetiracetam in a porous matrix that disperses in water within a period of less than about 10 seconds is disclosed. Also disclosed are methods of preparing the dosage form and of treating a condition, disease or disorder that is therapeutically responsive to levetiracetam.

Polymers and compositions, collectively 'bioadhesive materials', with improved bioadhesive properties have been developed. One or more compounds comprising: a) an aromatic moiety comprising two or more hydroxyl substituents, methoxy substituents, substituents hydrolyzable to hydroxyl substituents, or a combination thereof, and b) a primary or secondary amino moiety are either covalently attached to a polymer or are physically mixed with a polymer to form a bioadhesive material. These bioadhesive materials can be used, for example, to fabricate new drug delivery or diagnostic systems with increased residence time at tissue surfaces, and consequently increase the bioavailability of a drug or a diagnostic agent.

Bioadhesive polymers

A process is provided for making dry, micronized particles of an agent, such as a drug. The method includes (a) dissolving a macromolecular material, preferably a polymer, in an effective amount of a solvent, to form a solution; (b) dissolving or dispersing the agent in the solution to form a mixture; (c) freezing the mixture; and (d) drying by vacuum the mixture to form solid particles of the agent dispersed in solid macromolecular material. The micronization in this process occurs directly in a macromolecular matrix and hardening of the particles of agent by solvent removal takes place by lyophilization of the bulk matrix, which stabilizes the drug particles during hardening and prevents coalesence, thereby resulting in smaller final drug particles. The method is particularly preferred for protein agents. The process can be used in conjunction with a standard microencapsulation technique, typically following separation of the agent from the macromolecular matrix. The process yields microparticles having a homogenous size distribution, preferably less than 2 &#x3bc;m, and more preferably less than 1 &#x3bc;m, in size. The microparticles have well defined, predictable properties, which is particularly critical in drug delivery applications.

Micronized freeze-dried particles

Methods for inducing a thermoplastic polymer, which can be non-mesogenic, to exhibit liquid crystalline properties have been developed. The method includes the steps of (a) heating the polymer from an initial temperature below its glass transition temperature (Tg) to a temperature greater than its Tg and below its melting temperature (Tm); (b) exposing the polymer to a pressure greater than about 2 metric tons/in , preferably between about 2 and 10 metric tons/in , preferably for at least about one minute, while maintaining the temperature greater than its Tg; and (c) cooling the polymer below the Tg while maintaining the elevated pressure. Unlike many prior art transition processes which are reversible, this process provides a liquid crystal state that can be maintained for years at ambient conditions. In a preferred embodiment, the plastics are bioerodible thermoplastic polymers, such as polyanhydrides, some polyesters, polyamides, and polyaromatics. The liquid crystalline polymers can be used in the controlled release or retention of substances encapsulated in the polymers. The polymer can be in a variety of forms including films, film laminants, and microparticles. In a preferred embodiment, the LC polymers are used to encapsulate therapeutic, diagnostic, or prophylactic agents for use in medical or pharmaceutical applications.

Liquid crystalline polymers

The invention involves methods and products for oral gene therapy. Genes under the control of promoters are protectively contained in microparticles and delivered to cells in operative form, thereby obtaining noninvasive gene delivery for gene therapy.

Method for gene therapy using nucleic acid loaded polymeric microparticles

A process for preparing nanoparticles and microparticles is provided. The process involves forming a mixture of a polymer and a solvent, wherein the solvent is present in a continuous phase and introducing the mixture into an effective amount of a nonsolvent to cause the spontaneous formation of microparticles.
