Objective: The study was carried out with an objective to achieve a potential sustained release oral drug delivery system of an antihypertensive drug, Perindopril which is a ACE inhibitor having half life of 2 hours. Perindopril is water soluble drug, so we can control or delay the release rate of drug by using release retarding polymers. This may also decrease the toxic side effects by preventing the high initial concentration in the blood.Method: Microcapsules were prepared by solvent evaporation technique using Eudragit L100 and Ethyl cellulose as a retarding agent to control the release rate and magnesium stearate as an inert dispersing carrier to decrease the interfacial tension between lipophilic and hydrophilic phase. Results: Prepared microcapsules were evaluated for the particle size, percentage yield, drug entrapment efficiency, flow property and in vitro drug release for 12 h. Results indicated that the percentage yield, mean particle size, drug entrapment efficiency and the micrometric properties of the microcapsules was influenced by various drug: polymer ratio. The release rate of microcapsules could be controlled as desired by adjusting the combination ratio of dispersing agents to retarding agents.Conclusion:Perindopril microcapsules can be successfully designed to develop sustained drug delivery, that reduces the dosing frequency and their by one can increase the patient compliance.

Aim: Because of its many actions, curcumin, a plant-derived polyphenolic substance found naturally in turmeric (Curcuma longa), has been the focus of a significant investigation. The utilization of safe, useful, and highly functional chemicals obtained from natural sources in human nutrition/prevention/therapy needs some modifications to achieve multifunctionality, enhance the bioavailability, and delivery methods, all to enhance their efficacy. Curcumin's limited water solubility, fast metabolism and removal from the body, and hence low bioavailability, are significant obstacles to its use. To address these issues, a variety of new drug delivery systems with multiple routes of administration have evolved. Encapsulating the medication in vesicular structures is one such technique that, if successful in enabling selective absorption, can be predicted to extend the drug's life in systemic circulation and reduce toxicity. As a result, several vesicular drug delivery methods, including liposomes, niosomes, transfersomes, and pharmacosomes, have been developed. Since then, developments in vesicular drug delivery have resulted in the creation of systems that enable drug targeting as well as the prolonged or controlled release of traditional medications. The present study aimed to develop and characterize curcumin-loaded niosomes. Design of Study: In present study 32 factorial method was used to formulate different formulations of niosomes containing curcumin. Place and Duration of Study: Department of Pharmacy, IFTM University Moradabad, From December to May 2021. Methodology: Various niosomal formulations of curcumin were developed by using surfactant and cholesterol by thin-film hydration technique. Total 9 formulations were developed and characterized (32 factorial designs). Results: Formulation N7 was considered as an optimized formulation since formulation F7 has maximum drug entrapment and a prolonged drug release rate. The present study suggests that the concentration of surfactant and cholesterol affects % drug loading efficiency of niosomes. The percentage entrapment efficiency of niosomes increases on the increasing concentration of surfactant (Span 60) and cholesterol but above a certain concentration of cholesterol further increment in cholesterol concentration reduces drug entrapment efficiency of niosomes.

The term “Phyto” means plant and “some” means cell It is also mentioned as herbosomes this is a new patented technology, where standardized plant extracts or water soluble phytoconstituents are complexed with phospholipids to produce lipid compatible molecular complexes, there by greatly increasing absorption and bioavailability. The recent development and conducted works of various researchers have been studied thoroughly to establish the transdermal route as a potential way to deliver phytoconstituents. Plant derived products or plant extracts are increasingly receiving attention as dietary supplements for the homeostatic management of inflammation, toxicities, cancers, weight loss and other chronic or acute degenerative disorders. But these products frequently face stability and bioavailability problems. Plant products after their isolation become prone to instability and are potentially unfit to cross the bio membrane as such. The phytosome technique reduces these tasks to reasonable extents. The phytosome or Herbosome technique increases the hydrophilicity of highly lipophilic drug there by making it suitable for drug delivery and increases the lipophilicity of hydrophilic phytoconstituents adequately to cross biological membrane. The topical application of phytosomes for cosmetic purpose has already been proven. This review also contains a comparative account of liposomes and phytosomes along with recent advancements in the field of phytosome technology with a special concern to transdermal drug delivery. The poor oral bioavailability of polyphenolic compound can be enhanced through the incorporation of them into phospholipid based self-assembled delivery system, i.e. popularly known as phytosome. There are number of products available in the market that contains phytosomal drug delivery system such as Ginkgo biloba, Silybum marianum, and Camellia sinensis.
