Erroneous introduction of femoral venous catheter into a broad ligament varicose vein causing hemoperitoneum in a woman with postpartum thrombotic microangiopathy.

Femoral venous catheterization is a common procedure in critical care patients. Pregnant women and those in the postpartum period are at risk of various complications such as shock, acute kidney injury, and thrombotic microangiopathic syndromes requiring hemodialysis and plasma exchange, which may necessitate central venous catheterization. Femoral vein catheters may also sometimes be needed.

QbD approach of rapid disintegrating tablets incorporating indomethacin solid dispersion.

The development of rapid disintegrating tablets (RDT) requires the use of highly soluble components to support the intended use of these products. In an attempt to prepare RDT of indomethacin, its solid dispersion with polyvinyl pyrrolidone K25 (PVP) was incorporated in a fast disintegrating matrix. Drug polymer interactions were investigated using X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR).

Effect of some formulation parameters on flurbiprofen encapsulation and release rates of niosomes prepared from proniosomes.

Proniosomal gels or solutions of flurbiprofen were developed based on span 20 (Sp 20), span 40 (Sp 40), span 60 (Sp 60), and span 80 (Sp 80) without and with cholesterol. Nonionic surfactant vesicles (niosomes) formed immediately upon hydrating proniosomal formulae. The entrapment efficiency (EE%) of flurbiprofen (a poorly soluble drug) was either determined by exhaustive dialysis of freshly prepared niosomes or centrifugation of freeze-thawed vesicles.

Quality by design: understanding the formulation variables of a cyclosporine A self-nanoemulsified drug delivery systems by Box-Behnken design and desirability function.

Quality by design (QBD) refers to the achievement of certain predictable quality with desired and predetermined specifications. A very useful component of the QBD is the understanding of factors and their interaction effects by a desired set of experiments. The present project deals with a case study to understand the effect of formulation variables of nanoemulsified particles of a model drug, cyclosporine A (CyA).

Formulation of anastrozole microparticles as biodegradable anticancer drug carriers.

The purpose of this study was to develop poly(d,l-lactic-co-glycolic acid) (PLGA)-based anastrozole microparticles for treatment of breast cancer. An emulsion/extraction method was used to prepare anastrozole sustained-release PLGA-based biodegradable microspheres. Gas chromatography with mass spectroscopy detection was used for the quantitation of the drug throughout the studies.

Formulation and optimization of mouth dissolve tablets containing rofecoxib solid dispersion.

The purpose of the present investigation was to increase the solubility and dissolution rate of rofecoxib by the preparation of its solid dispersion with polyvinyl pyrrolidone K30 (PVP K30) using solvent evaporation method. Drug-polymer interactions were investigated using differential scanning calorimetry (DSC), x-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). For the preparation of rofecoxib mouth dissolve tablets, its 1:9 solid dispersion with PVP K30 was used with various disintegrants and sublimable materials.
