Mucoadhesive Films For Treatment Of Local Oral Disorders: Development, Characterization And In Vivo Testing, Sandeep K. Ramineni
Mucoadhesive Films For Treatment Of Local Oral Disorders: Development, Characterization And In Vivo Testing, Sandeep K. Ramineni
Theses and Dissertations--Biomedical Engineering
Mucoadhesive drug delivery systems which are being used from 1980’s to avoid first pass metabolism of drugs, commercially exist for only systemic drug delivery with fast erosion times (15-60 min), that may not be appropriate for local oral disorders. The goal of this research was to develop and characterize mucoadhesive films with flexibility of carrying different drugs and proteins and provide sustained release for local treatment of oral disorders.
Mucoadhesive films composed of polyvinylpyrrolidone (PVP) and carboxymethlycellulose (CMC) were formulated with imiquimod, an immune response modifier. Problems such as solubilization of imiquimod to increase drug loading, uniformity in films and …
Microsphere Spray System For Wound Coverage, Nicholas J. Andersen
Microsphere Spray System For Wound Coverage, Nicholas J. Andersen
Theses and Dissertations--Biomedical Engineering
Spinal fusion is used to treat diseases or disorders of the spine by fusing together two or more vertebrae. Two associated risks with spinal fusion are infection and blood loss. Administration of tranexamic acid is used to prevent blood loss, and transfusions are given following blood loss. Surgical site infections are prevented with vancomycin powder spread into the surgical wound, while established infections are treated by debridement and delivery of antibiotics for 4 to 6 weeks. The present research explored an alternate method to prevent and treat blood loss or infection in spinal fusion. Poly(lactic-co-glycolic acid) (PLGA) microspheres was used …
Development Of A Moldable Composite Bone Graft Substitute Releasing Antibacterial And Osteogenic Drugs, Matthew E. Brown
Development Of A Moldable Composite Bone Graft Substitute Releasing Antibacterial And Osteogenic Drugs, Matthew E. Brown
Theses and Dissertations--Biomedical Engineering
Large infected bone defects (IBD) are very complicated to treat due to their high variability; they often require multiple procedures. Bone autografts are the gold standard for treatment but have several drawbacks, such as a need for a second surgery site, limited grafting material, and donor site morbidity. The objective of this research was to develop a moldable synthetic bone grafting material capable of releasing both antimicrobial and osteogenic drugs over a clinically relevant time course for the treatment of IBDs. Current treatment methods for large IBDs require two separate procedures to treat the bone defect and the infection.

Bioerodible Calcium Sulfate Bone Grafting Substitutes With Tailored Drug Delivery Capabilities, Bryan R. Orellana
Bioerodible Calcium Sulfate Bone Grafting Substitutes With Tailored Drug Delivery Capabilities, Bryan R. Orellana
Theses and Dissertations--Biomedical Engineering
Bone regeneration or augmentation is often required prior to or concomitant with implant placement. With the limitations of many existing technologies, a biologically compatible synthetic bone grafting substitute that is osteogenic, bioerodible, and provides spacing-making functionality while acting as a drug delivery vehicle for bioactive molecules could provide an alternative to ‘gold standard’ techniques.
In the first part of this work, calcium sulfate (CS) space-making synthetic bone grafts with uniformly embedded poly(β-amino ester) (PBAE) biodegradable hydrogel particles was developed to allow controlled release of bioactive agents. The embedded gel particles’ influence on the physical and chemical characteristics of CS was …
Additives To Control Mechanical Properties And Drug Delivery Of Injectable Polymeric Scaffolds, Paul Fisher
Additives To Control Mechanical Properties And Drug Delivery Of Injectable Polymeric Scaffolds, Paul Fisher
Theses and Dissertations--Biomedical Engineering
In situ forming implants (ISIs) are popular due to their ease of use and local drug delivery potential, but they suffer from high initial drug burst, and release behavior is tied closely to solvent exchange and polymer properties. Additionally, such systems are traditionally viewed purely as drug delivery devices rather than potential scaffold materials due to their poor mechanical properties and minimal porosity. The aim of this research was to develop an injectable ISI with drug release, mechanical, and microstructural properties controlled by micro- and nanoparticle additives.
First, an injectable ISI was developed with appropriate drug release kinetics for orthopedic …
