The study aimed to improve the transdermal permeation of IBU utilizing menthosomes as a vesicular carrier. IBU-loaded menthosomes were formulated by thin film hydration & optimized using 2³ factorial designs (Design Expert® version 13 software). In vitro & ex vivo skin permeation analysis of IBU-encapsulated menthosomes was studied across the rat skin sample. In vivo pharmacodynamic activity was studied in an arthritis rat model. The optimized IBU-loaded menthosomes exhibited an optimum vesicle size of 214.2 ± 2.96 nm, Zeta potential of -21.1 ± 2.72 mV, (PDI) Polydispersity Index of 0.267 ± 0.018 with Entrapment efficiency (EE%) of 78.7 ± 2.73 %. The in vitro & ex vivo skin penetration study displayed enhanced release of drug of 77.02 ± 1.0 % and 40.91 ± 0.81 % respectively, compared to conventional liposomes. In vivo pharmacodynamic study on carrageenan-induced paw edema in Wistar albino rats demonstrated superior anti-inflammatory activity of the optimized IBU-encapsulated menthosomes (**p < 0.01) and effective inhibition of paw edema (34.04 ± 0.155 %). The formalin test indicated a significant analgesic effect of optimized formulation during the chronic phase of analgesia (*p < 0.05) compared to the control group. Thus, the developed and optimized drug-loaded menthosomes could serve as a suitable vesicular delivery carrier in enhancing the transdermal delivery of other NSAID drugs.

BACKGROUNDHeterotopic ossification (HO) is a relatively common complication after total hip arthroplasty (THA) and can range from a radiographic observation only to severely disabling and requiring revision surgery. Prophylaxis is recommended for high-risk patients, though the ideal method and targeted population are open to debate. Tranexamic acid (TXA) is a medication increasingly being used to reduce blood loss associated with orthopaedic surgeries, including THA.METHODSA retrospective review of 357 patients undergoing THA from November 2020 through December 2023 was conducted. The patients were grouped based on whether they received intravenous TXA perioperatively or not, and their propensity score matched 2:1 TXA to no TXA on age, body mass index, sex, Charlson Comorbidity Index, and perioperative celecoxib use. Univariate and multivariate analyses were performed.RESULTSAfter propensity score matching, the only significant differences between groups were American Society of Anesthesiologists (ASA) scores and preoperative celecoxib use between groups, as the TXA group had fewer patients who had an ASA of 3 or more (38.9 versus 58.5%, P < 0.001) and more patients who had taken celecoxib preoperatively (16.3 versus 5.9%, P = 0.010). Perioperatively, patients were more likely to undergo THA using the anterior approach (74.5 versus 57.6%, P = 0.002) and were more likely to receive postoperative celecoxib prescriptions (44.8 versus 31.4%, P = 0.021), but there was no difference in other nonsteroidal anti-inflammatory drug (NSAID) usage postoperatively. Postoperatively, patients who received TXA had a lower rate of HO on the last postoperative x-ray (20.1 versus 33.9%, P = 0.007). Multivariable logistic regression, to assess predictors of HO, found that patients who had TXA were 42% less likely to have visible HO (OR [odds ratio] = 0.58, P = 0.047), while holding surgical approach, American Society of Anesthesiologists score, preoperative and postoperative celecoxib use, and postoperative other nonsteroidal anti-inflammatory drug use constant.CONCLUSIONSThe use of TXA in patients undergoing primary THA results in a decreased likelihood ofHO formation on postoperative x-rays.

Treatment Patterns and Persistence Among Patients Newly Diagnosed With Migraine in South Korea: A Retrospective Analysis of Health Claims Data

BACKGROUND AND PURPOSEMigraine is one of the most common chronic neurological diseases worldwide. Although diverse treatment regimens have been recommended, there is insufficient evidence for which treatment patterns to apply in routine clinical settings.METHODSWe used nationwide claims data from South Korea for 2015-2021 to identify incident migraine patients with at least one prescription for migraine. Patients were categorized according to their initial treatment classes and followed up from the date of treatment initiation. Treatment regimens included prophylactic treatments (antidepressants, anticonvulsants, beta blockers, calcium-channel blockers, and renin-angiotensin-aldosterone system [RAAS] inhibitors) and acute treatments (acetaminophen, antiemetics, aspirin, ergotamine, nonsteroidal anti-inflammatory drugs [NSAIDs], opioids, and triptans). The treatment patterns of migraine were evaluated until the end of the study period, including the secular trends, prevalence, persistence, and changes in migraine treatment.RESULTSAmong the 761,350 included patients who received migraine treatment, the most frequently prescribed acute treatment was an NSAID (69.9%), followed by acetaminophen (50.0%). The most-prescribed prophylactic treatment was flunarizine (36.9%), followed by propranolol (24.4%). Among the patients, 54.8% received acute treatment, 13.5% received prophylactic treatment, and 31.6% received both treatment types. However, 65.7% of the patients discontinued their treatment within 3 months. The 3-month persistence rate was highest for triptans (25.2%) among the acute treatments and for RAAS inhibitors (62.0%) among the prophylactic treatments.CONCLUSIONSWhile the prevalence rates of medication use were found to align with current migraine guidelines, frequent switching and rapid discontinuation of drugs were observed in routine clinical settings.
