Introduction Colloid drug delivery systems (CDDSs) are vesicular dosage forms. They include liposomes niosomes nanospheres and nanocapsules. Their size avoids any risk of embolism following intravenous injection. CDDSs were initially designed, and were studied, as drug carriers for targeting purposes. The assumption was the expected ability of CDDSs to concert the drug at the therapeutic target and/or divert if from the toxicological one. Some interesting results have been obtained with drugs possessing a narrow …showed first 75 words of 2553 total…
