Non-steroidal anti-inflammatory drugs (NSAIDs), i.e. indomethacin used for rheumatoid arthritis and non-rheumatoid inflammatory diseases, are known for their injurious actions on the gastrointestinal (GI) tract. Mucosal damage can be avoided by using nanoscale systems composed by a combination of liposomes and biodegradable natural polymer, i.e. chitosan, for enhancing drug activity. Aim of this study was to prepare chitosan-lipid hybrid delivery systems for indomethacin dosage through a novel continuous method based on microfluidic principles...

Preterm birth is the major challenge in obstetrics affecting ~10% of pregnancies. Pan-prostaglandin synthesis inhibitors (NSAID) prevent preterm labor and prolong pregnancy but raise concerns about fetal renal and cardiovascular safety. We conducted preclinical studies examining the tocolytic effect and fetal safety of the oral prodrug candidate OBE022 and its parent OBE002, both potent and highly selective antagonist of the contractile PGF2α prostaglandin receptor (FP). Efficacy of OBE022 and OBE002, alone and in combination with other tocolytics, was assessed in human tissues and pregnant animal models for inhibition of uterine contraction and delay of parturition...

Ischemia/reperfusion injury holds a key position in many pathological conditions such as acute kidney injury and in the transition to chronic stages of renal damage. We hypothesized that besides a reported disproportional activation of vasoconstrictor response, hypoxia/reoxygenation (H/R) adversely affects endothelial dilatory systems and impairs relaxation in renal arteries. Rat renal interlobar arteries were studied under isometric conditions. Hypoxia was induced by application of 95% N2 , 5% CO2 for 60 min to the bath solution, followed by a 10 min period of reoxygenation (95% O2 , 5% CO2 )...

A useful animal model of intestinal injury is pivotal for studying its pathogenesis and developing nutritional interventions (e.g., amino acid supplementation). Here, we propose the use of indomethacin (IDMT) to induce intestinal inflammation in neonatal pigs. Fourteen-day-old piglets fed a milk replacer diet receive intraperitoneal administration of IDMT (5 mg/kg body weight) for 3 consecutive days. On day 4, blood and intestinal samples are obtained for physiological and biochemical analyses. IDMT increases blood DAO activity, I-FABP concentration, neutrophil and eosinophil numbers; intestinal MMP3 mRNA levels, MPO activity, and MDA concentration; but reduces the plasma concentration of citrulline (synthesized exclusively by enterocytes of the small intestine), intestinal GSH-Px activity, and mRNA levels for villin , I-FABP , TRPV6 , AQP10 , and KCNJ13 ...

Vapor-phase deposited polymer coatings are applied on thin indomethacin films to modify the drug release. Hydrogel-forming co-polymers of 2-hydroxyethyl methacrylate and ethylene glycol dimethacrylate were prepared directly on top of solution cast indomethacin thin films by initiated Chemical Vapor Deposition (iCVD). This technique allows for solvent-free processing under mild conditions, thus minimizing a potential impact on the pharmaceutical. The drug release behavior, among other properties, was evaluated for polymers of different compositions and at different temperatures...

REVIEW
Sanjay Prakash, Bansi Adroja
Hemicrania continua (HC) is an indomethacin responsive primary chronic headache disorder which is currently classified as a subtype of trigeminal autonomic cephalalgias (TACs). It is not very uncommon. There are >1000 cases of HC in the literature, and it constitutes 1.7% of total headache in the clinic settings. Misdiagnosis for HC is very common at all clinical settings. A diagnosis of HC is missed even by neurologists and headache specialists. It is characterized by a continuous strictly unilateral headache with superimposed exacerbations...
