Systematic Approach in the Development of Chitosan Functionalized Iloperidone Nanoemulsions for Transnasal Delivery, In Vitro and In Vivo Studies.

Iloperidone, a second-generation USFDA approved antipsychotic and BCS class II drug shows poor oral bioavailability of 28%. The present research deals with optimization of transnasal nanoemulsions of Iloperidone using Design Expert (Version 11) and further surface functionalization with chitosan for potentiating nose to brain delivery. Chitosan functionalized transnasal Iloperidone nanoemulsions were developed using oleic acid, charge inducer, Tween 80, Transcutol HP and chitosan using ultrasonication technique and evaluated.

Topical delivery of mupirocin calcium nanostructured lipid carriers using a full-thickness excision wound healing model.

Objective: Treatment of contaminated wounds represents a significant challenge in healthcare and there is a need to develop approaches maximising skin retention to maintain therapeutic concentrations of anti-infectives at the wound site. The objective of the present study was to develop and evaluate mupirocin calcium nanolipid emulgels to enhance wound healing performance and patient acceptability.

Methods: Nanostructured lipid carriers (NLCs) of mupirocin calcium were prepared by the phase inversion temperature method using Precirol ATO 5 (Gattefosse, India) and oleic acid as lipids and Kolliphor RH 40 (BASF, India) as surfactant and further incorporated into a gel base for topical delivery.

A Review on Recent Advances in Mannose-Functionalized Targeted Nanocarrier Delivery Systems in Cancer and Infective Therapeutics.

Unmodified nanocarriers used in the chemotherapy of cancers and various infectious diseases exhibit prolonged blood circulation time, prevent enzymatic degradation and increase chemical stability of encapsulated therapeutics. However, off-target effect and lack of specificity associated with unmodified nanoparticles (NPs) limit their applications in the health care system. Mannose (Man) receptors with significant overexpression on antigen-presenting cells and macrophages are among the most admired targets for cancer and anti-infective therapeutics.

Borneol: a Promising Monoterpenoid in Enhancing Drug Delivery Across Various Physiological Barriers.

Incorporation of permeation enhancers is one of the most widely employed approaches for delivering drugs across biological membranes. Permeation enhancers aid in delivering drugs across various physiological barriers such as brain capillary endothelium, stratum corneum, corneal epithelium, and mucosal membranes that pose resistance to the entry of a majority of drugs. Borneol is a natural, plant-derived, lipophilic, volatile, bicyclic monoterpenoid belonging to the class of camphene.

Nanolipid Gel of an Antimycotic Drug for Treating Vulvovaginal Candidiasis-Development and Evaluation.

This paper focuses on the development and evaluation of mucoadhesive vaginal gel of fluconazole using nanolipid carriers to enhance tissue deposition in treating vulvovaginal candidiasis. Treatment of vulvovaginal candidiasis includes antimycotic agents prescribed for 1 to 7 days or longer, in relapse either orally or topically. The delivery of fluconazole as nanolipid carriers in vaginal gel can be proposed as suitable alternative to the existing conventional formulations to improve the patient acceptability, compliance and localized drug action.

Studies on Solubility Enhancement of Poorly Soluble NSAID Using Dual Approach of Micro-environmental pH Modulation and Melt Granulation.

Background: The present work describes the role of melt granulation and microenviron-mental pH modulation technique in solubility enhancement of a poorly water soluble NSAID, Aceclofenac (ACL). ACL is a BCS Class II drug showing dissolution rate limited absorption and pH dependent solubility, with higher solubility at alkaline pH. The limited solubility of ACL affects drug absorption and hence, therapeutic effect as the drug is indicated in conditions of pain where rapid onset of action is desired.

Self nanoemulsifying granules (SNEGs) of meloxicam: preparation, characterization, molecular modeling and evaluation of in vivo anti-inflammatory activity.

Meloxicam, a BCS class II drug belonging to the class of NSAIDs is indicated in conditions of rheumatoid arthritis, ankylosing spondylitis and osteoarthritis in which rapid onset of drug action is desired to reduce inflammation and pain. The objective of the study was to thus develop Self Nanoemulsifying Granules (SNEGs) of Meloxicam (MLX) for enhancement of solubility; and subsequently dissolution rate, thus aiming for a faster onset of action. Preliminary studies along with molecular modeling studies were carried out for selection of appropriate lipids, surfactants and cosurfactants for the development of MLX-loaded Self Nanoemulsifying preconcentrate (SNEP).

Stability Indicating HPTLC Determination of Meloxicam.

A simple, selective, precise and stability-indicating high-performance thin layer chromatographic method of analysis of meloxicam both as a bulk drug and in formulation has been developed. The mobile phase selected was ethyl acetate:cyclohexane:glacial acetic acid (6.5:3.
