Formulation, Evaluation, and Characterization of Indapamide Niosomes

Niosomes, also known as nonionic surfactant vesicles, are one of the many carriers used to carry drug molecules to their target sites. They can hold both hydrophilic and hydrophobic medicines. Indapamide is an angiotensin II type 1 receptor (AT1) antagonist medication primarily used to treat high blood pressure. Niosomes containing Indapamide were created utilizing the thin film hydration process with various cholesterol concentrations and nonionic surfactants (span 60). All noisome formulations were assessed for entrapment efficiency, drug content, reproducibility, vesicular diameter, shape and size distribution microphotography, FTIR analysis, and in vitro release experiments. The results indicate that in all of the created niosomal formulations, as the surfactant content increases, the entrapment efficiency also increases. The drug content ranged between 90.06±0.57 and 96.15±0.42, with a low standard deviation. Niosomes range in size from 0.280±0.098µm to 0.299±0.044µm and have a spherical shape. The IR spectrum analysis indicated no interaction between the medication and the formulation ingredients. Membrane diffusion cells were used to study the in vitro dissolution parameters. The results demonstrate that formulation F6 had a better-controlled release action than other formulations, with an 'n' value of 0.917, indicating that the medication was released using zero-order kinetics.
