The current study was designed to develop a topical gel formulation for improved skin penetration of lornoxicam (LOR) for enhancement of its analgesic activity. Moreover, the effect of different penetration enhancers on LOR was studied. The LOR gel formulations were prepared by using hydroxylpropyl methylcellulose (HPMC) and carbopol. The carbopol gels in presence of propylene glycol (PG) and ethanol were developed. The formulated gels were characterized for pH, viscosity, and LOR release using Franz diffusion cells. Also, in vitro skin permeation of LOR was conducted. The effect of hydroxypropyl β-cyclodextrin (HP β-CD), beta-cyclodextrin (β-CD), Tween 80, and oleic acid on LOR permeation was evaluated. The optimized LOR gel formulation (LORF8) showed the highest flux (14.31 μg/cm(2)/h) with ER of 18.34 when compared to LORF3. Incorporation of PG and HP β-CD in gel formulation (LORF8) enhanced the permeation of LOR significantly. It was observed that LORF3 and LORF8 show similar analgesic activity compared to marketed LOR injection (Xefo). This work shows that LOR can be formulated into carbopol gel in presence of PG and HP β-CD and may be promising in enhancing permeation.

Pain is a dynamic and nonlinear experience shaped by injury and contextual factors, including expectations of future pain or relief . While µ opioid receptors are central to the analgesic effects of opioid drugs, the endogenous opioid neurocircuitry underlying pain and placebo analgesia remains poorly understood. The ventrolateral column of the posterior periaqueductal gray is a critical hub for nociception and endogenous analgesia mediated by opioid signaling .

Complex regional pain syndrome (CRPS) is a chronic pain disorder characterized by severe, disproportionate pain relative to an inciting event. The disorder's pathophysiology is complex, involving both central and peripheral nervous system alterations, alongside genetic, inflammatory, and psychological factors. Using data from TriNetX, this study investigated the impact of analgesic and adjuvant therapies on psychiatric outcomes in CRPS patients.

Background: In epidural anaesthesia, the addition of an adjuvant to local anaesthetics enhances the efficacy, thereby providing increased duration and intensity of blockade in lower limb surgeries. The aim was to compare the efficacy, onset, and duration of sensory and motor blockade; haemodynamic changes; and sedative and analgesic effects of nalbuphine, clonidine, and dexmedetomidine as an adjuvant to ropivacaine in epidural anaesthesia.
Methodology: A prospective, randomised, double-blind study among 90 patients after taking consent was divided into three groups (30 patients each; Group D received 15 ml of 0.

This study aims to study how gold nanoparticles (AuNPs) function in the recruitment and polarization of tumor-associated macrophages (TAMs) in hormone-sensitive prostate cancer (HSPC) and castration-resistant prostate cancer (CRPC). Phorbol ester (PMA)-treated THP-1 cells were cocultured with LNCaP or PC3 cells to simulate TAMs. Macrophage M2 polarization levels were detected using flow cytometry and M2 marker determination.
