A review on orodispersible drug delivery system

Abstract

The future of drug delivery holds great promise for orally dispersible dose formulations, which make application simple since no water requirement as compared to conventional solid dosage forms which requires significant volumes of fluids for administration. The objective for development of ODF provides a substitute for pills, syrups, and tablets in treating vomiting as well as nausea, particularly in children. On the basis of transdermal patch delivery system, a novel oral films drug delivery has been introduced. Fast dissolving films disintegrates quickly when come in contact with salivary secretion in the oral mucosa and released the drug fast approximately within 3 mins. ODFs are of different types, like sustained or controlled release, oral patches and fast dissolving films. They can be manufactured using a variety of method including solvent and semi solid casting, hot melt and solid dispersion extrusion, spray drying and rolling. Among them solvent casting method is the most employed method. ODFs comprises of active ingredient, polymer, plasticizer and additives like surfactants, sweetening and coloring agents. ODFs preparation requires hydrophilic polymer which provides quick dissolution in the oral cavity. Hydrophilic polymer act as base for ODFs formulation as they impart mouth feel and mechanical properties of the ODFs also dependent of polymer type. Oral thin-film provide fast drug dissolution precise dosage in a portable, safe, and handy manner that doesn't required water or any special equipment. This review article comprises of different methods for ODFs preparations, ODFs ingredients, ODFs benefits and drawbacks and their packaging.
