Repurposing losartan potassium against rheumatoid arthritis via transdermally-delivered leciplexes: Accentuated efficacy through modulation of angiotensin II/AT1R/AT2R axis.

ABSTRACT: Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory ailment which preferentially impacts the synovial membranes of joints and ultimately triggers cartilage and bone erosion. Angiotensin II (Ang II) participates in the pathogenesis of RA; hence, Ang II receptor blockade, accomplished through a specific inhibitor such as losartan potassium (LST), may confer an effective therapeutic avenue for RA. This study aimed to develop, optimize, and characterize LST-loaded leciplexes (LST-LPXs) to ameliorate its bioavailability and prolong its therapeutic efficacy for combating RA. To accomplish this objective, LST-LPX dispersions were assembled through a single-step process and optimized via D-optimal design for various physicochemical traits employing Design-Expert® software. Also, pharmac
