BACKGROUND: Use of dipyrone (metamizole) in perioperative and ICU pain therapy remains controversial due to a lack of solid evidence weighing dipyrone benefit against its potential life-threatening complications. Although dipyrone has known analgesic and antipyretic properties, its mechanisms of actions are incompletely understood. Although dipyrone effects on renal vasodilator prostaglandin synthesis are documented, little is known about its potential renal side effects, especially in the critical care environment...

Preclinical Research Metformin-dependent mechanisms have been implicated in the antinociceptive effect of some non-steroidal anti-inflammatory drugs (NSAIDs). In this study, the effect of local peripheral or systemic administration of metformin on the local peripheral or systemic antinociception induced by indomethacin, ketorolac and metamizole was assessed in the rat carrageenan-induced thermal hyperalgesia model. Rats were injected with carrageenan (1%, 50 µl) into the right hindpaw which reduced paw withdrawal latency, a measure of thermal hyperalgesia...

Metamizole can be used in both short- and long-term pain relief therapies and has a relatively favourable safety profile compared with classic NSAIDs. Metamizole is also infamous because of its potential fatal adverse drug reaction, agranulocytosis. Although this risk varies, it is estimated to occur in less than one million metamizole prescriptions. We describe a case of a 68-year-old patient who developed leukopenia after using metamizole.

We report on a 77-year-old male patient with neutropenic fever as a result of a newly diagnosed agranulocytosis. The patient was taking metamizole, which is a well known cause of agranulocytosis. The diagnosis of metamizole-induced agranulocytosis as an underestimated side-effect of metamizole could be confirmed by a bone marrow biopsy. The bone marrow and the blood count recovered completely after stopping the therapy with metamizole and administration of granulocyte colony-stimulating factor (G-CSF).

OBJECTIVE: To investigate the relationship between metamizol pharmacokinetics and the antinociceptive effect produced after subcutaneous administration of metamizol (177.8 mg/kg) alone or in combination with morphine (3.2 mg/kg), under acute and chronic treatments. METHODS: Antinociception was assessed using the pain-induced functional impairment model in rat (PIFIR). Serial blood samples were collected from the same animals to study the pharmacokinetics of metamizol...

Dipyrone (metamizole), a powerful drug, is widely used as an analgesic and antipyretic; however, the safety of its use during lactation and the potential impact on the offspring are not well established. This study aimed to determine the effect of maternal dipyrone treatment during lactation on offspring development and emotional behavior and on the dam's maternal behavior. Hence, on postnatal day (PND) 2, drinking water only or drinking water containing dipyrone at doses of 100, 300, and 500mg/kg/day, were offered to lactating mothers up to PND9...

BACKGROUND AND OBJECTIVES: Individuals who develop drug hypersensitivity reactions (DHRs) to chemically unrelated nonsteroidal anti-inflammatory drugs (NSAIDs) are considered cross-hypersensitive. The hallmark for this classification is that the patient presents a reaction after intake of or challenge with acetylsalicylic acid (ASA). Whether patients react to 2 or more NSAIDs while tolerating ASA remains to be studied (selective reactions, SRs). Objective: To identify patients with SRs to 2 or more NSAIDs including strong COX-1 inhibitors...

Metamizole (dipyrone) is a first-line, non-opioid analgesic used for postoperative pain management. Clinical data and animal experiments indicate a possible vasodilator action of this drug. We investigated the effects of metamizole on human artery and vein tone in an ex vivo model to assess potential contributions to venous pooling. Excess segments of bypass grafts were harvested during coronary artery bypass grafting procedures. Tensions were measured in an organ bath for 120 min after adding metamizole to the preconstricted vessels...

One third of operations are performed on an outpatient basis in Germany, but methods of postoperative pain therapy are less studied. We observed 126 patients with ambulatory and planned surgery in the field of orthopedics and trauma surgery. They were treated with the analgesic metamizole intra- and postoperatively and completed the patients' questionnaire QUIPS on the first postoperative day. In all, 79 patients (61.7%) reported current pain ≥4 on the numerical rating scale (NRS); 84 (66.6%) had restrictions in mobility, 48 (38...

BACKGROUND: Morphine, and analgesics other than morphine (AOM), are commonly used to treat postoperative pain after major surgery. However, which AOM provides the best efficacy-safety profile remains unclear. METHODS: Randomized trials of any AOM alone or any combination of AOM compared with placebo or another AOM in adults undergoing major surgery and receiving morphine patient-controlled analgesia were included in a network meta-analysis. The outcomes were morphine consumption, pain, incidence of nausea, vomiting at 24 h and severe adverse effects...

BACKGROUND: Nonopioid analgesic drugs may interfere with platelet inhibition by aspirin. Recent in vitro and clinical studies in patients with cardiovascular disease have suggested that this pharmacodynamic interaction may also occur with dipyrone, a nonopioid analgesic popular in Europe, Asia and South America. OBJECTIVE: Dipyrone is used extensively in acute and chronic pain. This study was undertaken to provide clinical data, so far missing, on its interactions in this group of patients...

BACKGROUND: This study investigates whether ultrasound-guided thoracic paravertebral blocks would improve postoperative analgesia in patients undergoing bilateral reduction mammaplasty. METHODS: After obtaining ethics committee approval, data of 70 patients who underwent bilateral reduction mammaplasty were reviewed. Sixty-four patients' data were evaluable; 30 were in the general anesthesia group and 34 were in the thoracic paravertebral block group. Data such as time to first pain, intraoperative fentanyl requirement, postoperative numeric rating scale scores, number of patients who required tramadol in the postoperative care unit, and rescue analgesic consumption through the first 2 postoperative days were analyzed...

BACKGROUND: Dipyrone (MET, metamizole) is a non-steroidal anti-inflammatory drug commonly used both in human and in veterinary medicine. After oral administration, is broken down rapidly to metabolites which largely retain the activity of the parent drug. Its metabolites have analgesic, antipyretic and anti-inflammatory effects. RESULTS: The subjects were eight healthy male Large White post-suckling piglets, weighing between 5.0 to 7.4 kg, of ages 35 ± 10 days...

RATIONALE: Oral anticoagulants and painkillers, some with an additional effect on the coagulation system, are widely used and are therefore prone to abuse and (intentional) overdose. We report the case of a patient with a massive mixed anticoagulant intoxication. PATIENT CONCERNS: The patient had ingested 1960 mg rivaroxaban, 31.5 mg phenprocoumon, 1425 mg diclofenac, and 21,000 mg metamizole in suicidal intention. DIAGNOSES: Massive mixed anticoagulant overdose...
