OBJECTIVES Carbon nanotubes (CNTs) have attracted much attention by researchers worldwide in recent years for their small dimensions and unique architecture, and for having immense potential in nanomedicine as biocompatible and supportive substrates, as a novel tool for the delivery of therapeutic molecules including peptides, RNA and DNA, and also as(More)
The work investigates the development and optimization of fenugreek (Trigonella foenum-graecum L.) seed mucilage (FSM)-alginate mucoadhesive beads containing metformin HCl through ionotropic gelation using 3(2) factorial design. The effect of polymer-blend ratio (sodium alginate to FSM) and cross-linker (CaCl(2)) concentration on the drug encapsulation(More)
The present study deals with preparation, optimization and in-vitro drug release study of hydroxyapatite (HAp)- ofloxacin for bone-implantable delivery in osteomyelitis treatment. The effect of drug amount added, and orthophosphoric acid addition rate as process parameters on the drug loading into HAp-system by precipitation method was optimized by using 32(More)
The paper describes development of aceclofenac-loaded pectinate-poly(vinyl pyrrolidone) [PVP] beads through ionotropic-gelation. Effects of amount of pectin and PVP on drug encapsulation efficiency (DEE), and cumulative drug release at 6h (R6h) were optimized by using response surface methodology. The optimized beads showed DEE of 96.58 ± 4.15% and R6h of(More)
For the determination of lenalidomide using carbamazepine as an internal standard, an ultra-fast stability indicating LC-MS/MS method was developed, validated and optimized to support clinical advancement. The samples were prepared by solid-phase extraction. The calibration range was 2-1000 ng mL(-1), for which a quadratic regression (1/x(2)) was best(More)
BACKGROUND Tuberculosis is considered as one of the deadliest diseases of human existence. Since ancient age the treatment of tuberculosis has been highly challenging primarily owing to the pathogenic nature of the Mycobacterium and its diverse spots of localization in human body including lungs, liver, spleen, eye, meninges and lymph nodes. METHODS The(More)
Zinc (Zn(2+))-ion induced diclofenac sodium (DS)-loaded alginate-okra (Hibiscus esculentus) gum (OG) blend beads was successfully formulated through Zn(2+)-ion induced ionic-gelation cross-linking method in a complete aqueous environment. Effects of polymer-blend ratio and cross-linker concentration on drug encapsulation efficiency (DEE) and cumulative drug(More)
The present work was employing the Quality by Design approach for the development and validation of a LC-MS-MS method to support the clinical advancement in determination of sildenafil in human plasma using lorazepam as an internal standard. Sample preparation involved solid phase extraction and calibration range observed between 3 and 1,700 ng/mL. The(More)
Alginate-based bipolymeric-nanobioceramic composite matrices for sustained drug release were developed through incorporation of nano-hydroxyapatite [nHAp] powders within ionotropically-gelled calcium ion-induced alginate-poly (vinyl pyrrolidone) blends polymeric systems. nHAp powders were synthesized by precipitation technique using calcium hydroxide(More)
PURPOSE For the determination of desloratadine (DES) and 3-OH desloratadine (3-OHD) in human plasma using deutrated desloratadine (DESD5) as internal standard (IS), a novel stability indicating liquid chromatography-tandem mass spectrometric method was developed and validated to support the clinical advancement. MATERIALS AND METHODS The solid-phase(More)
