Abstract

The use of herbal remedies is still a trend in the world, especially Indonesia as the second largest country after Brazil is rich in medicinal plants, in addition to having many pharmacological properties also have low side effects. The most common problems with biopharmaceutically related natural substances are low drug solubility, low biopharmaceutics, stability problems and active substance absorption. Bioavailability is an important factor in achieving the effects of drug therapy. Low bioavailability may occur due to low water solubility, instability in the digestion, and difficulty passing through the membrane. To overcome the problem of bioavaibility of natural material compounds should be made efforts to improve it, one of them with solid dispersion method. The solid dispersion is the dispersion of one or more active ingredients in an inert solid carrier. Technique of Dispersion in the carrier can be by way of hot spin mixing, co-evaporation, co-precipttion, freeze-drying, spray drying and HME. Techniques that are still rarely used in Indonesia is hot melt extrusion (HME). This study aims to explore characteristics of the chemical properties of natural materials, efforts to increase the bioavailability of natural compounds, and solid dispersion techniques.Keywords: Bioavailability, Natural compounds, solid dispersion, hot melt extrusion

Abstract

Hot Melt Extrusion (HME) at the beginning appeared widely used in the plastic industry and food industry, but in the last few decades, many researchers have succeeded in applying the HME method as a drug delivery system and determining various dosage forms in the pharmaceutical industry. The challenges that arise in the pharmaceutical are related to the solubility, dissolution rate, and bioavailability of drugs, especially for drugs that have low solubility in water. The low solubility and bioavailability will reduce the pharmacological effect of a drug. Solid dispersion using HME method succeeded in answering this challenge by distributing the drug evenly in the hydrophilic polymer during the extrusion process and changing the crystalline form to the amorphous form while maintaining drug stability. This review will examine the polymers are suitable for the HME method, Mechanism for solid dispersion using HME method, Steps must be taken to prepare solid dispersions using HME and characterization of solid dispersion resulting from HME and determinants of success of solid dispersions Keywords: Polymer, Solid Dispersion, hot-melt extrusion, Mechanism of solid dispersion, Step HME.
