Poly (DL-lactide-co-glycolide) nanoparticle-based inhalable sustained drug delivery system for experimental tuberculosis.
OBJECTIVES To improve the bioavailability of antitubercular drugs (ATDs) as well as to assess the feasibility of administering ATDs via the respiratory route, this study reports the formulation of three frontline ATDs, i.e. rifampicin, isoniazid and pyrazinamide encapsulated in poly (DL-lactide-co-glycolide) nanoparticles suitable for nebulization. METHODS Drug-loaded nanoparticles were prepa...
متن کاملPoly-DL-lactide-co-glycolide microspheres as a controlled release antigen delivery system.
Successful vaccine application means maximum protection with minimal number of administrations. A rational development of vaccines involves studies of the nature of the antigen as well as of the adjuvant to be used to improve the immune responses. This has provided the impetus for studies to design the degradable devices and for different approaches to antigen delivery by different routes of ad...
متن کاملAngiogenic and Osteogenic Coupling Effects of Deferoxamine-Loaded Poly(lactide-co-glycolide)-Poly(ethylene glycol)-Poly(lactide-co-glycolide) Nanoparticles
Angiogenesis and osteogenesis coupling processes are essential for bone regeneration, and human bone marrow stromal cells (hBMSCs) along with endothelial cells (ECs) are crucial participants. Deferoxamine (DFO), a hypoxia-mimetic agent, could activate the hypoxia-inducible factor (HIF)-1α signaling pathway and trigger angiogenic and osteogenic effects in these cells. However, the lifetime of DF...
متن کاملevaluation of polymer concentration effect on doxycycline hyclate drug release from in situforming system based on poly(lactide-co-glycolide)
in this study, doxycycline hyclate release behavior from in situ forming drug delivery systems investigated. these systems based on poly()lactide-co-glycolide)(50:50 dissolved in n-methyl-2-pyrrolidone that were evaluated in different concentrations. these systems are useful for local treatment of periodontal diseases. uv spectroscopy is used to determine drug concentration in release medium. a...
متن کاملPoly(D, L-lactide-co-glycolide)/Poly(ethylenimine) Blend Matrix System for pH Sensitive Drug Delivery
Poly(d,l-lactide-co-glycolide) (PLGA) and poly(ethylenimine) (PEI) were blended and found to form a homogeneous pH sensitive matrix for drug release. Differential scanning calorimetry (DSC) studies of the PLGA/PEI blends showed a single glass transition temperature at all compositions. Fourier transform infrared spectroscopy (FTIR) demonstrated that the PLGA carbonyl peak at 1760 cm 1 shifted t...
