Psoriasis is a chronic autoimmune skin disorder characterized by excessive epidermis thickening, keratinocyte proliferation, and angiogenesis, driven by the PI3K/Akt/mTORC1, one of the key signalling axis of psoriasis. Corticosteroids used for treatment have limited efficacy and numerous side effects, thereby necessitating the development of safer, targeted therapeutic options for improved disease management and patient outcomes. Here we address this problem by encapsulating the PI3K/Akt/mTORC1 inhibitor Rapamycin in lipid-polymeric conjugated hybrid nanoparticles (RPMN) and incorporating these particles in a carbopol-based hydrogel system (RPMNGel), with enhanced release kinetics, long-term stability, better spreadability over reported literature for the treatment of psoriasis, and skin residence time. Using an in-vivo imiquimod-induced psoriatic model, in comparison to free drug-loaded gels, RPMNGel showed increased accumulation and deeper epidermal penetration, and slower diffusion within the psoriatic skin without causing any side effects to normal skin. The cumulative psoriasis area severity index score reduced from 10.5 to 5. 1 at day 7 in the group treated with RPMNGel. Overall, our studies establish the efficacy of RPMNGel for improved psoriasis treatment and management through enhanced drug penetration, prolonged drug release and reduced systemic toxicity.
