Bioadhesive nanoparticles show promise for drug delivery

Improved i.p. drug delivery with bioadhesive nanoparticles.

The i.p. administration of chemotherapy in ovarian and uterine serous carcinoma patients by biodegradable nanoparticles may represent a highly effective way to suppress peritoneal carcinomatosis. However, the efficacy of nanoparticles loaded with chemotherapeutic agents is currently hampered by their fast clearance by lymphatic drainage. Here, we show that a unique formulation of bioadhesive na...

Cyclodextrin-gantrez Nanoparticles as Bioadhesive Carriers for Oral Drug Delivery

Introduction Oral delivery is the most convenient and desired way for drug delivery. The major factor determinant for bioavailability of orally administered drug is the membrane permeability and drug solubility in the intestinal lumen. Many drugs show bioavailability problems due to their low water solubility, slow dissolution rate and instability in the gastrointestinal tract. One possibility ...

Bioadhesive Microspheres for Tuberculosis Drug Delivery

Tuberculosis (TB) is an infectious disease that mainly affects the lungs. For the treatment of tuberculosis, conventional drug delivery system fails to achieve efficient drug delivery system fails to achieve efficient drug delivery at the target site. Today, bioadhesive microspheres became a topic of great interest as a novel carrier for drug delivery. Bioadhesive microspheres offers longer ret...

Bioadhesive Mini-Tablets for Vaginal Drug Delivery

Different non-ionic cellulose ethers (methyl cellulose, MC; hydroxyethyl cellulose, HEC; hydroxypropyl cellulose, HPC; hydroxypropylmethyl cellulose, HPMC) and microcrystalline cellulose (MCC) were investigated as matrix formers for preparation of mini-tablets targeting vaginal drug delivery. Hexyl aminolevulinat hydrochloridum (HAL) was used as a model drug. The mini-tablets were characterized...
