A comparative evaluation of diclofenac sodium transdermal patch, oral diclofenac sodium with intramuscular injections of diclofenac sodium in patients suffering from oral pain: A randomized control trial

Efficacy of Diclofenac Transdermal Patch in Therapeutic Extractions: A Literature Review

Diclofenac sodium is a nonsteroidal anti-inflammatory drug that effectively manages pain following therapeutic extractions. Post-extraction pain is commonly treated with non-steroidal anti-inflammatory drugs (NSAIDs). In addition to their high bioavailability and long duration of action, transdermal NSAIDS have several other advantages. The review tries to understand and elucidate the use of transdermal patches, here Diclofenac, as a postoperative pain management modality. Drug delivery is one of the essential aspects of drug administration where transdermal patches are to be found equally effective when compared to oral administration of drugs. Various analgesics can be administered as patches, for example, ketoprofen, diclofenac, etc. There are also comparative studies between diclofenac and ketoprofen to see and understand the efficacy of transdermal patches compared with oral administration. Compared to oral administration, transdermal patches offer numerous benefits. These include avoidance of first-pass metabolism, sustained and non-rapid absorption, steady plasma levels that remain for prolonged periods, lack of patient dependence on drugs, prevention of gastric distress, and flexibility of stopping delivery of medications by simply removing the patch. This review aims to examine the diclofenac transdermal patch's effectiveness in reducing postoperative pain after orthodontic extraction.

Photo-assisted peroxymonosulfate activation via 2D/2D heterostructure of Ti3C2/g-C3N4 for degradation of diclofenac

In this paper, a two dimensional/two dimensional (2D/2D) heterostructure of Ti₃C₂/g-C₃N₄ (T/CN) was constructed and used to activate peroxymonosulfate (PMS) for the degradation of diclofenac (DCF) in water in the presence of light illumination. Compared with single photocatalytic process by T/CN (0.040/min) and with pure g-C₃N₄ nanosheets in PMS system (0.071/min), 5.0 and 3.0 times enhanced activities were achieved in the T/CN-PMS system at optimum Ti₃C₂ (1.0 wt%) loading under light illumination (0.21/min). Moreover, the decomposing processes of DCF in T/CN-PMS system were applicable in a wide initial pH range (3∼14), therefore, overcoming the limitation of pH dependence in traditional PMS system. Based on the synergistic effect of photocatalysis and PMS oxidation processes, the ¹O₂ was generated as primary reactive species for the removal of DCF in T/CN-PMS system. The DCF degradation mechanism was further proposed through the results of liquid chromatography-mass spectrometry (LC-MS) and density functional theory (DFT) calculations.
