Controlled Release Ammonio Methacrylate Copolymer-Based Microspheres of Oxypentifylline

The objective of this work was to formulate and evaluate a controlled-release Oxypentifylline microspheres that fulfill the requirements for extended release medications using Ammonio Methacrylate Copolymer RS100 as polymeric material. The microsphere were prepared by quasiemulsion solvent diffusion technique. The effect of process variables such as drug to polymer ratio, stirring rate, and con...

Block Copolymer Micelles as Nanocontainers for Controlled Release of Proteins from Biocompatible Oil Phases

Biocompatible oils are used in a variety of medical applications ranging from vaccine adjuvants to vehicles for oral drug delivery. To enable such nonpolar organic phases to serve as reservoirs for delivery of hydrophilic compounds, we explored the ability of block copolymer micelles in organic solvents to sequester proteins for sustained release across an oil-water interface. Self-assembly of ...

Release of macromolecules from albumin-heparin microspheres

Hydrophilic microspheres based on albumin-heparin conjugates have been prepared as a macromolecular delivery system. The soluble albumin-heparin conjugate was synthesized and crosslinked in a water-in-oil emulsion with glutaraldehyde to form microspheres in the same manner as for albumin microsphere preparation. The microspheres were characterized in terms of their size and swelling properties....

Development and Characterization of Controlled Release Ketoprofen Microspheres

Microspheres ketoprofen (KP) were prepared by o/w emulsion solvent evaporation technique using EudragitRS100 as a polymeric material. The effect of process variables such as drug: polymer ratio, stirring rate, emulsifier concentration, internal organic solvent and dispersing medium volumes were examined. The prepared formulations were characterized for particle size distribution, percent yield,...

Controlled Release of Drugs from Microparticles Produced by Ultrasonic Assisted Atomization Based on Biocompatible Polymers

Microencapsulation of active molecules in biocompatible polymers is a matter of great interest in pharmaceutical sciences. Ultrasonic assisted atomization as a new technique to produce microencapsulated systems seems to offer several advantages (low level of mechanical stress in materials, reduced energy request, reduced apparatuses size) with respect to more conventional techniques. In this wo...
