Sulfasalazine-induced drug rash with eosinophilia and systemic symptoms syndrome in a seronegative spondyloarthritis patient: A Case report.

The objectives were to evaluate drug rash with eosinophilia and systemic symptoms syndrome due to sulfasalazine and to carry out the pharmacoeconomic assessment associated with this adverse drug reaction (ADR). A 37-year woman was presented with rashes, fever, cough, and dyspnea. In the past 3 months, she was on sulfasalazine for inflammatory polyarthritis and seronegative spondyloarthritis.

High azithromycin concentration in lungs by way of bovine serum albumin microspheres as targeted drug delivery: lung targeting efficiency in albino mice.

Background: Following administration, the antibiotic travels freely through the body and also accumulates in other parts apart from the infection site. High dosage and repeated ingestion of antibiotics in the treatment of pneumonia leads to undesirable effects and inappropriate disposition of the drug. By way of targeted lung delivery, this study was intended to eliminate inappropriate azithromycin disposition and to achieve higher azithromycin concentration to treat deeper airway infections.

Improved intraocular bioavailability of ganciclovir by mucoadhesive polymer based ocular microspheres: development and simulation process in Wistar rats.

Background: The poor ocular bioavailability of the conventional eye drops is due to lack of corneal permeability, nasolacrimal drainage and metabolic degradation. To overcome this issue, drug encapsulated in mucoadhesive polymer based ocular microspheres have the advantages of improved drug stability, easy administration in liquid form, diffuse rapidly and better ocular tissue internalization.

Methods: The ganciclovir chitosan microspheres (GCM) were prepared by modified water-in-oil emulsification method.
