background microencapsulation is a useful method to prolong a drug release from dosage forms and to reduce its adverse effect (1) among various available methods. the microencapsulation of hydrophilic active ingredients requires the use of a polar dispersing phase such as a mineral oil. acetone/paraffin systems are conventionally used. objectives the current study aimed to investigate two diffe...

Colloidal drug carrier is one of the most important entities essentially required for successful transport of loaded drugs. They are drug vectors, which sequester, transport and retain the active drug en route, while they elute or deliver it within or in the vicinity of target. Targeting the drug to the desired site of action would not only improve the therapeutic efficacy but also enable a red...

solid lipid carriers – NLC. Particulate lipid matrices in the form of lipid pellets are known from the textbooks since many years, products are on the market (e. g. Mucosolvan retard, Boehringer-Ingelheim). After these lipid pellets as the first generation, P. Speiser developed so-called “lipid nanopellets for oral administration” in the middle of the eighties [1]. This system was not further d...

Liposomes are artificially prepared vesicles made of lipid bilayer. Liposomes can be filled with drugs, and used to deliver drugs for cancer and other diseases. Amongst the various carrier, few drug carrier reached the stages of clinical trails where phospholipid vesicles (liposome) show strong potential for effective drug delivery to the site of action. Liposomes can be composed of naturally-d...
