title: Diclofenac sodium injection (akis(®), dicloin (®)): a review of its use in the management of pain.
abstract: A novel formulation of diclofenac sodium suitable for subcutaneous or intramuscular injection (Akis(®), Dicloin(®)) has been developed using the complexing agent hydroxypropyl-β-cyclodextrin (HPβCD) as a solubility enhancer. Diclofenac HPβCD is available in several European countries, where it is indicated for use in adults with acute forms of pain, including postoperative pain. Clinical trials have demonstrated the analgesic efficacy of diclofenac HPβCD in terms of relieving moderate to severe postoperative pain in patients undergoing dental surgery or minor orthopaedic surgery. Subcutaneous diclofenac HPβCD also effectively relieved moderate to severe neuropathic pain, related to cancer or not. Diclofenac HPβCD was generally well tolerated in clinical trials, with injection-site reactions among the most commonly reported adverse events. The local tolerability of diclofenac HPβCD was consistently rated as 'good' or 'excellent' across all studies. Subcutaneous administration of diclofenac is a valid alternative to intramuscular delivery, with the advantages of easier administration, the availability of additional body sites suitable for injection and the potential for self-administration. Thus, diclofenac HPβCD 25, 50 or 75 mg/mL solution for subcutaneous or intramuscular injection extends the treatment options available for use in the management of pain in adults.
