Abstract:

      Several plant extracts and phytoconstituents, despite having excellent bioactivity in vitro, demonstrate less or no in vivo actions due to their poor lipid solubility or improper molecular size or destruction in gut. Drug delivery system for polyphenolic phytoconstituents (phytosomes) was prepared by complexing polyphenolic phytoconstituents with phospholipid mainly phosphatidylcholine which bind components to each other on a molecular level. Bioavailability is enhanced due to their capacity to cross the lipid rich bio-membranes and to protect the valuable components of the herbal extract from destruction by digestive secretions and gut bacteria. Phytosomes have the capacity to deliver the standardized plant extracts and phytoconstituents through several routes of drug administration. Only a few natural drugs have been formulated and are available in the market as phytosomes. With wide range of applications of phytosomes numerous studies are undergoing and lots more is expected in the forthcoming years. The techniques used for such formulations are patentable and highly profitable.

Phytosome- a Novel Approach for Herbal Drug Delivery

The bioavailability of some orally administered botanical extracts is erratic and poor due to limited gastro-intestinal absorption. Bioavailability can be improved by using new delivery systems which can enhance the rate and the extent of solubilization into aqueous intestinal fluids and the capacity to cross biomembranes. Phospholipids based drug delivery system have been found promising for b...

Application of Novel Drug Delivery System in Enhancing the Therapeutic Potential of Phytoconstituents

Various phytoconstituents obtained from nature have wide biological activities in chronic diseases and have wide therapeutic efficacy. The main advantage of using phytoconstituents is it provides free from adverse effects treatment where none of the medication can do. However, the physiochemical properties such as poor solubility, poor permeation, and non-targeting at the active site will creat...

Phyto-phospholipid complex: A tabular update

Phytoconstituents have been used in medicine science since ancient times due to their various pharmacological actions. But most of them (like flavanoids, terpenoids) are low in lipid solubility and have large molecular size due to complex multiple ring structure, causing poor absorption and poor bioavailability via oral route. The phytosome system of drug delivery results in increased bioavaila...

Design and Construction of Ph-Sensitive Drug Delivery System Based on Metal-Organic Framework (MOF) Nanoparticles for Cancer Treatment by Drug Delivery System Containing Curcumin

Introduction: Much research has been carried out to improve drug delivery and targeted drug delivery to the body in order to minimize side effects, provide controlled delivery of the drug to the desired location and to achieve optimal therapeutic effects. Zeolitic imidazolate-8 (ZIF-8) is a subset of MOFs that are biocompatible, stable in the aquatic environment and have adjustable porosity. In...

Phytosome-hyaluronic acid systems for ocular delivery of L-carnosine

This study reports on L-carnosine phytosomes as an alternative for the prodrug N-acetyl-L-carnosine as a novel delivery system to the lens. L-carnosine was loaded into lipid-based phytosomes and hyaluronic acid (HA)-dispersed phytosomes. L-carnosine-phospholipid complexes (PC) of different molar ratios, 1:1 and 1:2, were prepared by the solvent evaporation method. These complexes were character...
