Biodegradable microtablets made of low molecular weight polyglycolic acid: Bioabbaubare Mikrotabletten aus niedermolekularer Polyglycolsäure

1991

Research work in developing pharmaceutical dosage forms with biodegradable polymers seldom dealt with polyglycolic acid (PGA)1,2. This because of difficult processing procedures and low solubility of PGA in common organic solvents2,3. The only licensed product of the homoplymer in medical use is the sufgical suture Dexon®4

Iontophoresis: electrorepulsion and electroosmosis.

2000

Over the last 10-15 years, the electrical enhancement of drug delivery across the skin has undergone intense investigation. During this period, considerable amounts of experimental data have been generated, and the successful enhancement of a diverse array of molecules has been achieved. Indeed, the commercial exploitation of the method can be envisaged within the next few years. Despite this progress, however, the mechanistic understanding of iontophoresis remains a challenging scientific question that is yet to be fully resolved. The routes of permeation under the influence of an applied electrical potential, and the molecular interactions of the transporting drug with these pathways, hav…
