The present study aimed to explore the challenges and methods in order to increase the solubility of poorly aqueous soluble drug for improved bioavailability alongwith relative study of toxicity problems related to anti-tubercular drug.
Objective: The present research work of Amphotericin B Proniosomal gel focuses on improving patient compliance by reducing the side effects of conventional intravenous injections and minimizing the problem of physical stability and to localize drug at site of action.
Methods: Proniosomal gels are prepared by coacervation phase separation technique using different concentration of non-ionic surfactants (Span and Tween) for uniform vesicle formation, lecithin as permeation enhancer/membrane stabilizer and cholesterol as a vesicle cement providing prolonged release. Prepared gels were evaluated for their viscosity, pH, spreadability, entrapment efficiency, drug content uniformity, extrudability, in vitro drug release, permeability and stability studies.
Results: Among the nine formulations, F2 (containing 10 mg drug, 250 mg Span 60, 50 mg Soya lecithin) was found to be promising. Fourier Transform infra-red (FT-IR) spectra studies represented no interaction and physicochemical characteristics were found within the limits. The percentages of drug content and entrapment efficiency were determined to be 95.16%±0.40 and 94.20%±0.20, respectively. In vitro drug release was about 95.72%±0.30.
Conclusion: Proniosomal gel could constitute a promising approach for topical delivery of Amphotericin B by encapsulating it in non-ionic surfactant to provide patient compliance with cutaneous fungal infection, which was found to be safe, tolerable and efficacious.
Nanoemulsions are sub-micron sized emulsions that are undergoing detailed assessment as potential drug carriers for enhancing the delivery of therapeutic agents. These are to date the most developed nanoparticulate systems for the systemic delivery of active pharmaceutical for controlled drug delivery as well as targeting. These are the thermodynamically durable isotropic system, in which two incompatible liquids (water and oil) are blended to form a single homogenous phase by utilizing a required quantity of surfactants to achieve mixing with a droplet diameter approaching roughly in the range of 0.5–100 μm. They find applications in various fields such as cosmetics as well as are adopted in various routes of administration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
