In this study, our aim was to develop solid drug-cyclodextrin inclusion complex system having nanofibrous morphology in order to have fast-dissolving property and enhanced water-solubility of poorly water-soluble drug. Here, we prepared a highly concentrated aqueous solution of inclusion complex between sulfisoxazole and sulfobutyl ether7-beta-cyclodextrin (SBE7-β-CD, Captisol®), and then, with...

BACKGROUND Indirubin, isolated from the leaves of the Chinese herb Isatis tinctoria L, is a protein kinase inhibitor and promising antitumor agent. However, the poor water solubility of indirubin has limited its application. In this study, a supersaturatable self-microemulsifying drug delivery system (S-SMEDDS) was developed to improve the oral bioavailability of indirubin. METHODS A prototyp...

the supersaturatable self-microemulsifying drug delivery system (s-smedds) represents a new thermodynamically stable formulation approach wherein it is designed to contain a reduced amount of surfactant and a water-soluble polymer (precipitation inhibitor or supersaturated promoter) to prevent precipitation of the drug by generating and maintaining a supersaturated state in-vivo. the supersatur...

The poorly water soluble antidiabetic drug gliclazide was selected to study the effect of excipients on dissolution rate enhancement. Ordered mixtures of micronized gliclazide with lactose, mannitol, sorbitol, maltitol and sodium chloride were prepared by manual shaking of glass vials containing the drug and excipient(s). Different water soluble excipients, addition of surfactant and superdisin...

Background The FDA approved drug Efavirenz is a Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) successful first line drug of choice in Highly Active Anti-Retroviral Therapy (HAART) for treatment of HIV and AIDS. It is poorly water soluble drug (10 g/ml) with 40-45% of bioavailability and administered as high doses 600-800 mg/day. Increase in solubility can enhance bioavailability; provi...

Poorly water soluble molecules are typically formulated for improving their dissolution rate and storage stability by increasing active drug surface area that come in the contact with the dissolution medium [4]. Most important characteristics of nanosuspensions are their exhibited particle size; polydispersity index, drug saturation solubility, physical stability, dissolution rate and bioavaila...

The purpose of preparing Self microemulsifying drug delivery system in this work is to enhance the solubility and oral bioavailability of poorly water soluble drug, Glimepiride. SMEDDS are the isotropic mixture of surfactant, co-surfactant and oil incorporated with drug. In the aqueous media, gastro intestinal motility emulsification takes place. Glimepiride was undergone solubility studies in ...

Oral administration is the most commonly used and readily accepted form of drug delivery; however, it is find that many drugs are difficult to attain enough bioavailability when administered via this route. Polymeric micelles (PMs) can overcome some limitations of the oral delivery acting as carriers able to enhance drug absorption, by providing (1) protection of the loaded drug from the harsh ...
