The study aimed to develop and evaluate elastic liposomal gel formulations for the effective delivery of therapeutic agents to treat skin diseases. Various formulations of elastic liposomes were prepared, and their vesicle size, entrapment efficiency, and stability were assessed. The optimized formulation (F4) exhibited the smallest vesicle size (135.25 nm) and the highest entrapment efficiency (76.65%). Additionally, the corresponding elastic liposomal gel formulation (ELG2) was evaluated for drug content, pH, spreadability, and viscosity. ELG2 exhibited good drug content (98.85%), skin-friendly pH (6.82), and desirable spreadability (12.65 gm.cm/sec.). In-vitro drug release studies revealed that ELG2 demonstrated a sustained release profile, with 96.65% of the drug released at 10 hours. The release kinetics followed zero-order and Korsmeyer-Peppas models, indicating a controlled release mechanism. Stability studies confirmed the long-term stability of ELG2, with minimal changes in drug content and viscosity at both 4°C and 28°C. These results highlight the potential of the developed elastic liposomal gel for effective and stable drug delivery, making it a promising formulation for the treatment of dermatological conditions.
