Chitosan nanoparticles as a promising approach for pulmonary delivery of bedaquiline.

The purpose of the present research work was to explore chitosan nanoparticles (NPs) of a novel anti-tubercular drug, bedaquiline (BDQ) in order to reduce dose and side effects associated with oral BDQ formulation. The NPs were fabricated using ionic gelation method and evaluated for particle size, zeta potential, entrapment efficiency and drug loading. Plackett Burman was used as screening design.

Chitosan Nanoparticles of Gamma-Oryzanol: Formulation, Optimization, and In vivo Evaluation of Anti-hyperlipidemic Activity.

The elevated blood levels of cholesterol and low-density lipoproteins result in hyperlipidemia. The available expensive prophylactic treatments are kindred with severe side effects. Therefore, we fabricated the polymeric nanoparticles of gamma-oryzanol to achieving the improved efficacy of drug.

Dry-Powder Inhaler Formulation of Rifampicin: An Improved Targeted Delivery System for Alveolar Tuberculosis.

Background: The delivery of antitubercular drugs through direct lung targeting can lead to reduction in the dose as well as side effects of the drug. In the present investigation, carrier (lactose)-based dry-powder inhaler of rifampicin was prepared to achieve direct targeting of the drug into the lungs.

Methods: The dry powder inhaler formulation was prepared by simply mixing micronized rifampicin with coarse and fine lactose preblend.

Rifampicin loaded chitosan nanoparticle dry powder presents an improved therapeutic approach for alveolar tuberculosis.

Current treatment therapeutic approach for tuberculosis is the administration of first line drugs in the form of tablets and capsules for 4-6 months. However, this approach leads to severe adverse effects. Therefore, present study was designed to achieving local and sustained targeting of anti-tubercular drugs in order to reduce dose and frequency.

Combating Tuberculosis Infection: A Forbidding Challenge.

After 50 years drought, several drugs are looming from the pipeline to combat tuberculosis. They will serve as a boon to the field that has been burdened with primitive, inadequate treatments and drug-resistant bacterial strains. From the decades, due to lack of interest and resources, the field has suffered a lot.
