Efficacy of JOINS Tablet for Lumbar Spinal Stenosis: Prospective, Randomized, Open-Label Clinical Trial.
(PubMed, Medicina (Kaunas))
- "The control group was prescribed the usual spinal stenosis medications (Naproxen, Limaprost, and Pregabalin), while the test group was prescribed JOINS tablets in addition to the usual medications...At all follow-up periods, the functional outcomes did not show statistically significant differences between the test and control groups. The significant reduction in pain suggests that JOINS tablets may be an effective adjunct for pain relief, particularly in patients at high risk of adverse effects from long-term NSAID use."

REB methodology application on topical and oral NSAIDS' therapeutic benefit evaluation on acute pain related to musculoskeletal injuries
(PubMed, Therapie)
- "According to REB methodology, topical NSAIDs, unlike oral formulations, have demonstrated efficacy in managing acute pain related to musculoskeletal injuries. These results reinforce recent meta-analyses favoring topical NSAIDs and recommending to limit the use of oral NSAIDs due to a lack of proof in this indication. Finally, NSAIDs impact on tissue healing has not been objectively studied by RCTs in humans, so further research is warranted. The use of NSAIDs in trauma care may potentially evolve as new data and knowledge emerge."

Population Pharmacokinetics of Atogepant for the Prevention of Migraine.
(PubMed, Clin Pharmacokinet)
- P3 | "The pharmacokinetics of atogepant are similar in healthy participants and patients with CM or EM. Dose adjustments owing to intrinsic factors of age, sex, race, and body weight, or owing to concomitant medications consisting of P-glycoprotein (P-gp) inhibitors, BCRP inhibitors, oral contraceptive components (ethinyl estradiol and levonorgestrel), famotidine, esomeprazole, sumatriptan, acetaminophen, and naproxen are not necessary. Atogepant's popPK model provides a valuable tool for evaluating specific questions for patients, healthcare providers, and regulatory agencies. Integration into other modeling approaches has also aided in model-informed drug development decisions."

Gel-Phase Microextraction Using Microfluidic-Directed Ultrashort Peptide Assemblies for the Determination of Drugs in Oral Fluids.
(PubMed, Int J Mol Sci)
- "The peptide fibers co-assembled successfully with 5-fluorouracil (5-FU) and naproxen (39.8 ± 1.4 nmol of 5-FU and 27.4 ± 6.6 nmol of naproxen per 112 nmol of peptide used to prepare the fiber), resulting in a molar ratio drug/peptide ratio of approximately 1:3 and 1:4, respectively, demonstrating versatility in drug entrapment...The extension of the methodology to simulated saliva samples allowed extraction of 36% of 5-FU by the fiber, as determined by 19F NMR spectroscopy on microcoils, which enabled us to work with the small volume of fluid extracted from the microfluidic device and provided clean spectra and quantitative results. These findings highlight the potential of this tripeptide hydrogel as a sorbent material for therapeutic drug monitoring and toxicological analysis via a simple, non-invasive and rapid approach for drug detection in oral fluids."

Stable Analgesia, Reduced Hepatic Burden: Pharmacokinetic and Pharmacodynamic Advantages of Transdermal Diclofenac Tape(ZICTHORU® Tape) in Personalized Oncology Care
(ASA 2025)
- "Oral NSAIDs such as naproxen and diclofenac undergo significant hepatic metabolism during the first-pass effect, potentially exacerbating existing liver dysfunction, particularly in patients receiving hepatotoxic anticancer therapies such as tyrosine kinase inhibitors and immunotherapy agents...G represents the period, including nighttime, during which the concentration remains above the dashed-line threshold when 225mg ZICTHORU® Tapes is applied once a day. These pharmacokinetic characteristics suggest that ZICTHORU®Tapes provides a more stable and sustained plasma concentration, potentially enhancing pain management while minimizing peak-related side effects."

Novel Treatment Approach That Avoids High-dose Oral Steroids in a Patient With Relapsing Polychondritis
(ATS 2025)
- "Subsequently, a naproxen taper was initiated, and she was transitioned to methotrexate (7.5 mg once weekly) with folic acid supplementation...In addition, for patients such as the one described in this case who have RPC with mild to moderate organ involvement, current treatment recommendations are to initiate prednisone (1 mg/kg daily) before transitioning to a second-line agent, such as methotrexate, with concomitant dose reduction or cessation of oral glucocorticoids. This case demonstrated that oral glucocorticoids are not always necessary to achieve symptomatic improvement and that an oral NSAID may be sufficient. In such instances, patients are spared from exposure to high-dose oral steroids and the associated potential adverse effects, including increased risk of infection, fractures, hypertension, hyperglycemia, and dyslipidemia."
