ABSTRACT
AIM:
The present work is focus on development of anti-psoriasis activity of Karanjin (isolated from Pongamia pinnata seed oil) loaded liposome based lotion for enhancement of skin permeation and retention.METHOD:
Karanjin was isolated using liquid-liquid extraction method and characterised by HPLC analysis and partition coefficient. Further, isolated Karanjin was loaded into liposomes using thin-film hydration technique and optimised by Box-Behnken design. Selected optimised batch was characterised their mean diameter, PDI, zeta potential, and entrapment efficiency, morphology (by TEM), FTIR and ex-vivo skin retention. Additionally, Karanjin loaded liposomes were formulated into lotion and characterise their rheological, spreadability, texture, ex-vivo skin permeation & retention, stability and anti-psoriatic activity in mouse tail model.RESULT:
The yield of Karanjin from seed oil was 0.1% w/v and have lipophilic nature. The optimised liposomal formulation showed 195 ± 1.8 nm mean diameter, 0.271 ± 0.02 PDI, -27.0 ± 2.1 mV zeta potential and 61.97 ± 2.5% EE. TEM image revel the spherical shap of liposome surrounded by single phospholipid bilayer and no interection between drug and excipients. Further, lotion was prepared by 0.1% w/v carbopol and found to 615 mPa.sec viscosity, good thixotropic behaviour, spreadability and texture. There was 22.44% increase in drug permeation for Karanjin loaded liposomal lotion compared to pure Karanjin lotion, confirm by ex-vivo permeation and retention. While, in-vivo study revel the liposomal lotion of Karanjin was found to have 16.09% higher drug activity then 5% w/w conventional Karanjin lotion.CONCLUSION:
Karanjin loaded liposomal lotion have an effective anti-psoriatic agent and showed better skin permeation and retention than the conventional Karanjin lotion.Palavras-chave
