BACKGROUND: Zinc is known as an anti-inflammatory agent. Recent studies demonstrated the usage of zinc ions for enhancing the anti-inflammatory effect of Non-Steroidal Anti-inflammatory Drugs (NSAIDs). METHODS: This study compares the influence of chronic administration of zinc oxide nanoparticles (ZnO-NPs) and zinc oxide standard form (ZnO-S) on the anti-inflammatory and gastric activity of ketoprofen in rats. Both ZnO-S and ZnO-NPs were administered at doses of 7 or 14mg/kg (intraperitoneally (ip) and per os (po)) for 2 weeks followed by single po ketoprofen administration (in three doses: 5, 10, and 20mg/kg)...

Dexamethasone (DEX), a widely prescribed corticosteroid (CS), has long been the cornerstone for the treatment of inflammation and immunological dysfunctions in Rheumatoid Arthritis (RA). The CS are frequently used in combination with other anti-rheumatic agents such as nonsteroidal anti-inflammatory drugs (NSAIDs) and disease-modifying anti-rheumatic drugs (DMARDs) to mitigate disease symptoms and minimize unwanted effects. The steroid dose-sparing potential of the NSAID naproxen (NPX) was explored with in vitro and in vivo studies...

Most of non-steroidal anti-inflammatory drugs (NSAIDs) including ibuprofen at more than 1200 mg/day may generate gastrointestinal and cardiovascular side effects. Bilayer or multiparticulate devices have been developed for controlled release in order to prevent undesired side effects. A new "two release rate (2RR) monolithic tablets" approach is now proposed for controlled release of poorly soluble drugs, particularly NSAIDs. Ibuprofen was used as model drug. This concept is based on a calcium carboxymethyl-starch (CaCMS) complex as a novel, low-cost excipient for monolithic dosage forms easy to manufacture by direct compaction...

Naproxen (NPX) is a frequently used nonsteroidal anti-inflammatory drug for rheumatoid arthritis (RA). Lack of quantitative information about the drug exposure-response relationship has resulted in empirical dosage regimens for use of NPX in RA. Few studies to date have included sex as a factor, although RA predominates in women. A pharmacokinetic, pharmacodynamic, and disease progression model described the anti-inflammatory effects of NPX in collagen-induced arthritic (CIA) male and female rats. Three groups of rats were included for each sex: healthy animals, CIA controls, and CIA rats given a single 50-mg/kg dose of NPX intraperitoneally...

BACKGROUND: Ketorolac tromethamine is a non-steroidal anti-inflammatory drug (NSAIDs) that is widely used in the emergency department (ED) for the treatment of moderate-to-severe pain. Ketorolac, like other NSAIDs, exhibits an analgesic ceiling effect and previous research suggests that 10 mg is possibly the ceiling dose. Do the patterns of ketorolac dosing by emergency physicians follow its analgesic ceiling dose? METHODS: This was a single center retrospective, descriptive study to characterize patterns of ketorolac administration in ED patients...

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery is a safe and effective procedure for patients with severe obesity. One potential complication of LRYGB is the development of marginal ulcers (MUs). Nonsteroidal anti-inflammatory drugs (NSAIDs) are known to significantly increase the likelihood of developing marginal ulcers after surgery. However, the risk associated with low-dose aspirin consumption is not well defined. We examined the impact of daily low-dose aspirin (81 mg) on the development of marginal ulcers following LRYGB...

Combined administration of certain doses of opioid compounds with a non-steroidal anti-inflammatory drug can produce additive or supra-additive effects while reducing unwanted effects. We have recently reported that co-administration of metamizol with tramadol produces antinociceptive effect potentiation, after acute treatment. However, none information about the effect produced by the combination after chronic or repeated dose administration exists. The aims of this study were to investigate whether the antinociceptive synergism produced by the combination of metamizol and tramadol (177...

BACKGROUND: Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoinflammatory disease, which lacks an infectious genesis and predominantly involves the metaphysis of long bones. Common treatments range from nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids at first onset of disease, to immunosuppressive drugs and bisphosphonates in cases of insufficient remission. The therapeutic use of low-dose radiotherapy for CRMO constitutes a novelty. CASE REPORT: A 67-year-old female patient presented with radiologically proven CRMO affecting the right tibia/talus and no response to immunosuppressive therapy...
