The evaluation of isotretinoin induced adverse drug reactions
Adverse drug reactions (ADRs) are a major cause of morbidity and mortality and have become one of the major health problems. So assessment, detection and monitoring of ADRs allow us to prevent and manage ADRs. Currently, isotretinoin is the effective therapy for the treatment of severe recalcitrant nodular acne unresponsive to conventional therapy. It can cause severe adverse reactions and teratogenic effects. So,...

Design, formulation, optimization and evaluation of sustained release tablets of domperidone
Domperidone is widely used in the management of gastric disorders, particularly gastro esophageal reflux disorder and peptic ulcer. But the short half-life of domperidone leads to poor compliance and adverse reactions; that is why domperidone in sustained release dosage form is needed to achieve better therapeutic effects and to improve patient compliance. For this purpose sustained release tablets of domperidone...

Effect of ciprofloxacin and levofloxacin on some oxidative stress parameters in brain regions of male albino rats
The present study aimed to investigate the possibility of involved oxidative stress due to the oral administration of either ciprofloxacin or levofloxacin (under therapeutic level) in the three brain regions, cerebral cortex, hippocampus and striatum of male albino rats weighing (100 ± 20 g). The ciprofloxacin and levofloxacin administered groups exhibited significant elevation in lipid peroxidation (LPO), nitric...

Stability of anionic liposomes in serum and plasma
It is well-known that serum components destabilize liposomal membranes. Therefore, mostin-vitro transfection protocols avoid serum, which make the extrapolation to in-vivo situations difficult. In this study, we investigated the stability of different anionic liposomal formulations including artificial viral envelopes (AVEs) in 100% fetal calf serum (FCS), human serum (HS) and human plasma (HP) by...
