Recent Patents on Drug Delivery & Formulation - Volume 8, Issue 1, 2014

This patent review focuses exclusively on the oral delivery of mesalamine (5-ASA) and excludes oral mesalamine pro-drug and rectal delivery formulations. The formulation strategies of marketed formulations (Apriso®, Asacol®, Lialda® and Pentasa®) and non-marketed formulations are reviewed and explained by decoding formulation specifics that enable the site specific delivery for the treatment of inflammatory bowel disease.

The unique properties of carbon nanotubes (CNTs) make them a highly interesting and demandable nanocarrier in the field of nanoscience. CNTs facilitate efficient delivery of therapeutics like drugs, proteins, genes, nucleic acids, vitamins and lot more. Even though highly beneficial, the biocompatibility of CNTs is a major issue in their questioning their potential application in targeting drug delivery. Studies confirmed subd Read More

Drug delivery to the back of the eye following topical administration remains an unmet need for the scientific community. Treatment of posterior segment diseases requires localized and long-term drug delivery to the retina, choroid, and Bruch’s membrane. Until the last decade, there was limited evidence from large clinical trials that demonstrated the usefulness of pharmacotherapy compared to laser therapy or other vitr Read More

Taste masking is an important factor in the development of oral dosage forms containing bitter active pharmaceutical ingredients. Currently numerous techniques are being applied to overcome this problem. Realizing this, several researchers and pharmaceutical companies are now engaged in developing novel techniques to address the problem of taste masking evident by numerous patents filed in this area in recen Read More

The study was designed to investigate the in vitro dissolution profile and compression characteristics of colon targeted matrix tablets prepared with HPMC E15 LV in combination with pectin and Chitosan. The matrix tablets were subjected to two dissolution models in various simulated fluids such as pH 1.2, 6, 6.8, 7.2, 5.5. The fluctuations in colonic pH conditions during IBD (inflammatory bowel disease) and the nature of less fluid Read More

Spray drying has always remained an energetic field of innovation in pharmaceutical, food and flavor industry since last couple of decades. The current communication embodies an in-depth application of spray drying in pulmonary drug delivery for production of uniform and respirable size particles suitable for nebulizers, dry powder inhalers (DPI) and pressurized metered dose inhalers (pMDI). The review also highlights spra Read More
