Abstract
Purpose: To prepare solid lipid nanopaticles (SLNs) of Ketoprofen (KP) using microwave method. Ketoprofen (KP) is 2-(3-benzolphenyl) propionic acid with anti-inflammatory, analgesic and antipyretic property. The drug has short half-life of 120 mins. It belongs to BCS Class II drug. Gastric irritation is a major limitation for delivery because of acidic nature of the drug. Development of solid lipid nanoparticles with its transdermal drug delivery was the aim of present work.
Methods: Microwave-assisted microemulsion technique was used for the development of solid lipid nanoparticles. Stearic acid was used as lipid and tween 80 was used as surfactant. By varying the type of lipid and input energy watt, batches were formulated. SLNs were evaluated for zeta potential, drug entrapment, particle size and in-vitro drug release. Crystallinity behaviour was determined by differential scanning calorimetry and powder X-ray diffraction. Anti-inflammatory activity was evaluated for batch M4 of SLNs. The gel was prepared for M4 batch. It was evaluated for viscosity, pH, drug content, in-vitro and ex-vivo diffusion study.
Results: SLN were developed successfully. Based on the size, entrapment efficiency, stability and drug release, batch M4 was selected. SLNs showed 74.8% entrapment efficiency. Forty-fold improvement was observed in the solubility. The particle size was of 682.9 nm and average size of 1047 nm. PDI was 0.685. Zeta potential was -29.5 mV. M4 SLNs batch of gel showed burst release followed by a controlled release for 8 hrs in in-vitro drug release.
Conclusion: SLNs were successfully prepared by Microwave-assisted microemulsion technique. SLNs with anti-inflammatory activity was successfully developed with its transdermal delivery.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
