Abstract: A therapeutic sustained delivery vehicle (TSDV) includes a plurality of microparticles with pirfenidone (PFD) within a poly(lactic-co-glycolic acid) (PLGA) matrix, where the microparticles are suspended in a hyaluronic acid (HA) solution. This suspension of microparticles are useful for injection into a joint that suffers from osteoarthritis (OA) inflammation and pain. The microparticles are microspheres formed by forming a solution of PDF and PLGA in a water insoluble organic solvent that is emulsified with an aqueous solution. Upon evaporation of the organic solvent the resulting microspheres are separated from the suspension. The microspheres are suspended in a HA solution. An OA treatment is a periodic injection protocol that provides a long-term in vivo controlled-release PFD to modulate and attenuate the OA progression.
