Drug induced liver injury is a common cause of acute liver failure (ALF). While most of these cases are due to dose dependent hepatotoxicity with acetaminophen, idiosyncratic drug-induced liver injury (DILI) is responsible for about 15% cases of ALF. Antibiotics are the most common cause of idiosyncratic DILI as well as DILI induced ALF. Etodolac is a selective cycloxygenase- 2 (COX -2) inhibitor non-steroidal anti-inflammatory drug used as an analgesic and anti-inflammatory in musculoskeletal diseases. Severe liver impairment is extremely rare...

  The removal of organic matter and etodolac (an anti-inflammatory pharmaceutical) from a real process wastewater by using powdered activated carbon (PAC) adsorption before and after Fenton oxidation has been studied. The wastewater sample is collected from the final stage of chemical synthesis of a pharmaceutical (etodolac). Fenton oxidation resulted with decrease in chemical oxygen demand (84% removal) and etodolac concentration was reduced to 0.7 mg L-1. Optimum adsorption equilibrium conditions were found as t = 16 hours, and m = 10 g L-1...

INTRODUCTION: Heterotopic ossification (HO) after hip surgery is the formation of bone in non-skeletal tissue, usually between the muscle and the joint capsule. HO after hip surgery may be associated with clinical sequelae such as pain, impingement and decreased range of motion, compromising surgical outcomes. CASE REPORT: A 20-year-old basketball player presented with a 2-year duration of the left groin pain after a basketball-related injury. Due to continued disability and failure of conservative management the patient underwent hip arthroscopy...

Context: Biochemical weakening of the amnion is a major factor preceding preterm premature rupture of membranes (PPROMs), leading to preterm birth. Activation of matrix metalloproteinases (MMPs) is known to play a key role in collagen degradation of the amnion; however, epithelial to mesenchymal transition (EMT) that is also induced by MMP activation has not been investigated as a mechanism for amnion weakening. Objective: To measure amniotic EMT associated with vaginal delivery (VD) compared with unlabored cesarean sections (CSs), and to assess changes in amniotic mechanical strength with pharmacologic inhibitors and inducers of EMT, thus testing the hypothesis that EMT is a key biochemical event that promotes amniotic rupture...

Combinational therapy has become increasingly popular in recent times due to various advantages like greater therapeutic effect, reduced number of prescriptions, lower administrative costs, and an increase in patient compliance. Drug-drug multicomponent adducts could help in combination of drugs at supramolecular level. Two drug-drug eutectics of etodolac with paracetamol (EP) and etodolac with propranolol hydrochloride (EPHC) were successfully designed and synthesized for the first time. These eutectics significantly improved dissolution and material properties...

Non-steroidal anti-inflammatory drugs (NSAIDs) were differentiated from steroidal anti-inflammatory medicines to help clinicians who needed to use anti-inflammatory agents that were safer than steroids. With market entry of rofecoxib in 1999, NSAIDs were then further classified into traditional NSAIDs and cyclooxygenase (COX)-2 inhibitors (coxibs), the latter posing potentially fewer gastrointestinal risks. In 2005, rofecoxib was withdrawn from the market because of concerns about the risk of heart attack and stroke with long-term use, and clinical practice began focusing more on the cardiovascular versus gastrointestinal safety of coxibs...

BACKGROUND: It is well known that radiation exposure to the heart and the use of non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of myocardial infarction (MI). Some NSAIDs are also known to act synergistically with ionizing radiation and have radio-sensitizing effects in radiotherapy. These evidences suggest that NSAIDs may affect the risk of MI after radiation exposure to the heart. In the present study, we investigated effects of NSAIDs on radiation-induced expression of cell adhesion molecules and COX-2, which are associated with inflammation and an increased risk of MI, in human endothelial cells...

Etodolac, a member of non steroidal anti-inflammatory drugs (NSAIDs), has a poor aqueous solubility. Long term administration of etodolac causes severe gastrointestinal disturbances such as peptic ulcer and bleeding. These disturbances could be overcome by alternative routes such as a topical administration. In the present study, pluronic lecithin organogels (PLOs) were prepared by simple mixing of pluronic solution with lecithin solution. Etodolac was loaded into the prepared gels or added during the gel formation...
