Injectable drug delivery systems R. Dinarvand, PhD Professor of Pharmaceutics
Injection routes • Intravenous (I.V.) • Immediate availability of drugs • Constant level difficult • Size limitation • RES uptake • Intramascular (I.M.) • Very common • Slow release • Subcutaneous (S.C.) • Similar to I.M. • Slower release
Injectable systems • Traditional formulations • Oil solvents • Less soluble salts • Particulate systems • Lipid based • Liposomes • Polymeric systems • Nanoparticles • microparticles • In situ gel forming systems • Erythrocytes • Bioconjugates
Polymeric systems • Biodegradable polymers • Nano for IV administration • Less as drug depo • Mainly as targeting agents • Surface treatment • MAB • PEG • Folate • Transferin
Conjugates • Albumin • Hyalorunic • PLGA • PEG • MAB
