BACKGROUND: Osteoarthritis (OA) is a degenerative joint disease produced by a cascade of events that can ultimately lead to joint damage. The aim of this study was to evaluate the effect of adelmidrol, a synthetic palmitoylethanolamide analogue, combined with hyaluronic acid on pain severity and modulation of the inflammatory response in a rat model of monosodium iodoacetate (MIA)-induced osteoarthritis. METHODS: OA was induced by intra-articular injection of MIA in the knee joint...

Leukocyte infiltration, improved levels of intercellular adhesion molecule 1 (ICAM-1), and oxidative stress in the colon are the principal factors in inflammatory bowel disease. The goal of the current study was to explore the effects of adelmidrol, an analog of the anti-inflammatory fatty acid amide signaling molecule palmitoylethanolamide, in mice subjected to experimental colitis. Additionally, to clarify whether the protective action of adelmidrol is dependent on the activation of peroxisome proliferator-activated receptors (PPARs), we investigated the effects of a PPARγ antagonist, GW9662, on adelmidrol action...

The aim of study was to examine the anti-inflammatory and analgesic effects of adelmidrol, an analogue of palmitoylethanolamide (PEA), in animal models of acute and chronic inflammation [carrageenan-induced paw edema (CAR) and collagen-induced arthritis (CIA)]. In order to elucidate whether the action of adelmidrol is related to activation of peroxisome proliferator-activated receptors (PPAR-α or PPAR-γ), we investigated the effects of PPAR-γ antagonist, GW9662 on adelmidrol mechanism. CAR induced paw edema, hyperalgesia and the activation of pro-inflammatory NF-κB pathway were markedly reduced by treatment with adelmidrol...

This study aimed to investigate potential new target(s)/mechanism(s) for the palmitoylethanolamide (PEA) analogue, adelmidrol, and its role in an in vitro model of contact allergic dermatitis. Freshly isolated canine keratinocytes, human keratinocyte (HaCaT) cells and human embryonic kidney (HEK)-293 cells, wild-type or transfected with cDNA encoding for N-acylethanolamine-hydrolysing acid amidase (NAAA), were treated with adelmidrol or azelaic acid, and the concentrations of endocannabinoids (anandamide and 2-arachidonoylglycerol) and related mediators (PEA and oleoylethanolamide) were measured...

The role of skin mast cells (MCs) in wound healing has been extensively investigated. The present study was designed to examine the effect of the aliamide adelmidrol on MCs during healing of experimental cutaneous wounds. Adelmidrol gel or the vehicle alone was applied 3 times daily on 5-mm punch biopsy wounds created on the thoracolumbar skin of 10 dogs. Wounds were allowed to heal by secondary intention. Eight-mm punch samples of the healing wounds were taken on days 1, 2, 4, 8, and 14, for histology...

AIM: The aim of this paper was to show that self-assessed anxiety in patients with pelvic visceral discomforts is reduced after the intravaginal administration of adelmidrol. MATERIAL AND METHODS: Twenty-four patients who described themselves as anxious (scoring 5 or more in a 1 to 10 scale in a self-assessment test) and who suffered from pelvic visceral discomfort (during defecation, urination, sexual intercourse and menstruation) were enrolled in the study. Pelvic visceral discomforts were assessed using a questionnaire in which patients were asked to assign a score between 1 and 10 according to intensity...

BACKGROUND: Adelmidrol is a semisynthetic derivative of azelaic acid and analogue of the anti-inflammatory compound palmitoylethanolamide (PEA). Based upon its physicochemical properties, adelmidrol is suitable for topical application. The main objective of the present study was to evaluate the efficacy of a topical adelmidrol emulsion on early and late inflammatory responses in hypersensitive dogs. Repeated intradermal injections of Ascaris suum extract were performed in both lateral thoracic areas of six conscious hypersensitive Beagle dogs, topically treated during 8 consecutive days...

Twenty client-owned dogs diagnosed with gingivitis were studied over a 45-day period in order to investigate the effect of professional dental prophylaxis combined with the use of a topical mucoadhesive gel containing adelmidrol, an aliamide. A non-intrusive papillary-marginal-gingival index (PMGI) was measured at each assessment, while the gingivitis index (GI) was measured only at the beginning and end of the study. Compared to the control group, the treated dogs had a significant decrease (P < 0.005) in the average GI index during the course of the study...

Palmitoylethanolamide (PEA) and some of its analogues have shown great efficacy in the treatment of pain and inflammation. Adelmidrol - the International Nonproprietary Name (INN) of the di-amide derivative of azelaic acid - is one of these analogues. The anti-inflammatory and analgesic effects of PEA and adelmidrol are hypothesized to be mediated, at least in part, by mast cell down-modulation. Mast cell mediators released at early stage of the inflammatory process drive the inflammatory reaction to chronicity as it happens in X-carrageenin-induced granulomatous tissue formation...

Recent studies have shown a correlation between an increased number of mast cells in patients with atopic dermatitis (AD) resulting in raised plasma levels of nerve growth factor (NGF), pointing to a possible key role of their interaction in the pathogenesis of AD. It is well known that mast cells synthesize, store and release NGF. Mast cells and NGF both appear to be involved in tissue inflammation and neuroimmune interactions, with NGF acting as a general "alert" molecule capable of recruiting and priming both local tissue and systemic defense processes following stressful events...
