This is Master of Pharmacy project on "solubility and dissolution enhancement of anti-diabetic drug using a noval surftab system" and describes an approach to enhance the Solubility of gliclazide by using solid dispersions (SDs) in polyethylene glycol 4000 (PEG 4000). Effective Date 3/3/2003 For More Information Call In Case of Emergency Call 856−423−6300. What is it? Polyethylene glycol, referred to as PEG, is used as an inactive ingredient in the pharmaceutical industry as a solvent, plasticizer, surfactant, ointment and suppository base, and tablet and capsule lubricant. particles with high water solubility [4]. It can be blended with other PEG molecular weights to achieve the desired properties, i. The dissolution test shows a 4. CARBOWAX™ Polyethylene Glycol 300 by Dow Chemical is a polyethylene glycol (PEG) liquid. can be transformed by a number of procedures: the lithium acetate/single-stranded carrier DNA/polyethylene glycol (LiAc/SS-Carrier DNA/PEG) method, 1-3 elec- troporation, 4-6 agitation with glass beads, 7 and bombardment with DNA-coated microprojectiles. Potassium maintains intracellular tonicity, is required for nerve conduction, cardiac, skeletal and smooth muscle contraction, production of energy, the synthesis of nucleic acids, maintenance of blood pressure and normal renal function.
