A modified ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for the quantitation of ibuprofen enantiomers in human plasma. Ibuprofen and flurbiprofen (internal standard) were extracted from human plasma at acidic pH, using a single-step liquid-liquid extraction with methyl-tert-butyl ether. The enantiomers of ibuprofen and flurbipr...

BACKGROUND Patent ductus arteriosus (PDA) is an important risk for heart failure due to left to right shunt in term neonates. OBJECTIVES In this study, we evaluated the effect of high dose ibuprofen in closure of PDA in term neonates. PATIENTS AND METHODS We used double dose ibuprofen (20 mg/kg, 10 mg/kg, and 10 mg/kg) for 3 - 30 day old term neonates with PDA who were admitted in the neona...

INTRODUCTION Preterm infants are at increased risk of having a patent arterial duct (PAD). PADs may cause congestive heart failure, respiratory distress, necrotizing enterocolitis, and renal impairment. Consequently, in some infants, it becomes necessary to attempt closure of the PAD. Surgical closure can be difficult in small infants and is not without its risks; thus, medical closure offers a...

BACKGROUND We conducted a prospective, randomized, single-masked pilot study with the principal aim of comparing efficacy and tolerance between oral and intravenous ibuprofen in early closure of patent ductus arteriosus in very low birth weight infants. The possibility of ductal closure with only 1 or 2 doses of treatment was a secondary objective. MATERIAL AND METHODS Sixty-four very low bir...

objective(s): in this research, zeolite x and zeolite y were used as vehicle to prepare intestine targeted oral delivery systems of indomethacin and ibuprofen. materials and methods: a soaking procedure was implemented to encapsulate indomethacin or ibuprofen within synthetic zeolites. gravimetric methods and ir spectra of prepared formulations were used to assess drug loading efficiencies into...

OBJECTIVE Prostaglandin E2 (PGE2) synthesis is modulated by COX2. Changes in PGE2 could be used to quantify the COX2 inhibition after ibuprofen administration. This study investigated the pharmacokinetic and pharmacodynamic relationships for COX2 inhibition according to three formulations of ibuprofen in healthy male subjects. MATERIALS AND METHODS A randomized, open-label, single-dose, three...

A randomized, controlled, double-masked clinical trial was conducted with a combination antiviral-antimediator treatment for experimental rhinovirus colds. In all, 150 healthy men and women (aged 18-51 years) were randomly assigned to 1 of 3 groups: intranasal interferon (IFN)-alpha2b (6 x 10(6) U every 12 h x 3) plus oral chlorpheniramine (12 mg extended release) and ibuprofen (400 mg) every 1...

intraventricularhemorrhage (ivh) is one of thecommon morbidities among preterm neonates. in thepresentstudy, we set out to evaluate the efficacy of two prophylactic modalities (ibuprofen and indomethacin prophylaxis) for prevention of ivh in our local setting. a prospective study was carried out in akbar-abadi hospital, tehran-iran (2013-2014). ninety-six preterm neonates who cared in closed in...
