Chitosan/bovine serum albumin layer-by-layer assembled particles for non-invasive inhaled drug delivery to the lungs.

Layer-by-Layer (LbL) assembly of polyelectrolytes on a solid core particle is a well-established technique used to deliver drugs, proteins, regenerative medicines, combinatorial therapy, etc. It is a multifunctional delivery system which can be engineered using various core template particles and coating polymers. This study reports the development and in-vitro evaluation of LbL assembled particles for non-invasive inhaled delivery to the lungs.

Mucoadhesive chitosan-poly (lactic-co-glycolic acid) nanoparticles for intranasal delivery of quetiapine - Development & characterization in physiologically relevant 3D tissue models.

Quetiapine hemifumarate (QF) delivery to the CNS via conventional formulations is challenging due to poor solubility and lower oral bioavailability (9 %). Similarly, many other second-generation antipsychotics, such as olanzapine, clozapine, and paliperidone, have also shown low oral bioavailability of <50 %. Hence, the present work was intended to formulate QF-loaded biodegradable PLGA-NPs with appropriate surface charge modification through poloxamer-chitosan and investigate its targeting potential on RPMI-2650 cell lines to overcome the limitations of conventional therapies.

A Nanoemulgel for Nose-to-Brain delivery of Quetiapine - QbD-Enabled formulation development & in-vitro characterization.

Second-generation antipsychotics, quetiapine hemifumarate (QF), exhibited highly active against negative and positive signs of psychosis. However, contemporary reports have shown that long-term therapy with QF causes lethal thrombocytopenia and leukopenia. Hence, to circumvent the drawbacks of available therapies, the current work aimed to design a QF-loaded biodegradable nanoemulsion (QF-NE) with suitable surface charge modification by poloxamer-chitosan and evaluate its targeting efficiency against RPMI-2650 cell lines.

Updated landscape of inhaled medications to combat COVID-19.

Plain language summary The COVID-19 pandemic has overwhelmed the healthcare systems worldwide. This calls for development of medicines that work effectively to decrease the death toll and severity of the infection. These medicines should be easy to administer to maintain patient compliance.

Topical nanocarriers for management of Rheumatoid Arthritis: A review.

Rheumatoid arthritis (RA) is a systemic autoimmune disease manifested by chronic joint inflammation leading to severe disability and premature mortality. With a global prevalence of about 0.3%-1% RA is 3-5 times more prevalent in women than in men.

Design strategies and evolving role of biomaterial assisted treatment of osteosarcoma.

Osteosarcoma is the most commonly diagnosed form of bone cancer. It is characterized by a high risk of developing lung metastasis as the disease progresses. Standard treatment includes combination of surgical intervention, chemotherapy and radiotherapy.
