PURPOSE: Eperisone is an oral muscle relaxant used in musculoskeletal disorders causing muscle spasm and pain. For more effective pain control, eperisone is usually prescribed together with nonsteroidal anti-inflammatory drugs (NSAIDs). As such, eperisone may have been overlooked as the cause of anaphylaxis compared with NSAIDs. This study aimed to analyze the adverse drug reaction (ADR) reported in Korea and suggest an appropriate diagnostic approach for eperisone-induced anaphylaxis...

OBJECTIVE: Eperisone hydrochloride is used in the treatment of musculoskeletal disorders as a muscle relaxant via blocking of calcium channels. In this study, we aimed to investigate the within-subject variability (CVwR ) of reference eperisone formulation for highly-variable drugs and to perform bioequivalence study of two oral formulations (sugar- and film-coated tablets) of eperisone hydrochloride 50 mg in healthy subjects by reference-replicated crossover study. MATERIALS AND METHODS: 36 healthy Korean male subjects were recruited, and 33 subjects completed the study...

Genetic variation in Cdk5 Regulatory Associated Protein 1-Like 1 (CDKAL1) is associated with the development of type 2 diabetes (T2D). Dysfunction of CDKAL1 impairs the translation of proinsulin, which leads to glucose intolerance. Eperisone, an antispasmodic agent, has been shown to ameliorate glucose intolerance in Cdkal1-deficient mice. We have launched a phase II clinical study to investigate the potential anti-diabetic effect of eperisone in T2D patients carrying risk or non-risk alleles of CDKAL1. The primary endpoint is the change of hemoglobin A1c (HbA1c) levels...

Dissociative convulsions or pseudoseizures are a difficult to treat common psychiatric condition. In a subset of these patients, the chief complaint is clenching of teeth with apparent nonresponsiveness alone. Neither drugs nor psychotherapeutic interventions have been found to be of much help in its management. Report of two such subsets of cases is presented, in which patients with dissociative convulsions showed sudden, dramatic, and sustained good response to the addition of a muscle relaxant eperisone.

Eperisone hydrochloride (EH) is widely used as a muscle relaxant for patients with muscular contracture, low back pain, or spasticity. Human serum albumin (HSA) is a highly soluble negatively charged, endogenous and abundant plasma protein ascribed with the ligand binding and transport properties. The current study was undertaken to explore the interaction between EH and the serum transport protein, HSA. Study of the interaction between HSA and EH was carried by UV-vis, fluorescence quenching, circular dichroism (CD), Fourier transform infrared (FTIR) spectroscopy, Förster's resonance energy transfer, isothermal titration calorimetry and differential scanning calorimetry...

PURPOSE: Pelubiprofen is a novel nonsteroidal anti-inflammatory, analgesic, and antipyretic drug with at least similar efficacy and better tolerability compared with other nonsteroidal anti-inflammatory, analgesic, and antipyretic drugs such as naproxen and aceclofenac. Eperisone hydrochloride is a centrally acting muscle relaxant that performs by blocking calcium channels. The combined use of pelubiprofen and eperisone hydrochloride is increasingly anticipated to promote the clinical effectiveness of pelubiprofen in relieving musculoskeletal symptoms of osteoarthritis, rheumatoid arthritis, and low back pain...

Here, we report a case of a 30-year-old male who was prescribed eperisone hydrochloride for body pain and loose stools after which he developed severe maculopapular rash. Eperisone hydrochloride is an analgesic and antispastic drug used for spastic diseases such as spastic paralysis in cerebrovascular diseases, cervical spondylosis, and periarthritis. The drug is marketed in most of the Asian countries including India, but it is not licensed. Studies show the history of hypersensitivity in other countries, but this is the first reported case in India...

This paper reports the validation of a quantitative high performance liquid chromatography-photodiode array (HPLC-PDA) method for the simultaneous analysis, in mouse plasma, of eperisone hydrochloride and paracetamol by protein precipitation using zinc sulphate-methanol-acetonitrile. The analytes were resolved on a Gemini C18 column (4.6 mm × 250 mm; 5 μm particle size) using a gradient elution mode with a run time of 15 min, comprising re-equilibration, at 60°C (± 1°C). The method was validated over the concentration range from 0...

A method was developed for rapid toxicological analysis of eperisone, tolperisone, and tizanidine in human serum using a MonoSpin® C18 extraction column and LC/MS/MS. The method was validated for LOD, linearity, precision, and extraction recovery. This method was rapid with an LOD of 0.5 ng/mL, linearity range 1-500.0 ng/mL (r2 = 0.999), and RSD value below 14.6%. Extraction recovery from the sample was greater than 98.6, 98.8, and 88.5% for eperisone, tolperisone, and tizanidine, respectively. Results showed that combination of the MonoSpin C18 extraction column and LC/MS/MS is a simple and rapid method for the analysis of these three analytes, and a method is described for simultaneous quantitative determination of the analytes in human serum by LC/MSIMS...
