A simple and reliable precolumn derivatization liquid chromatography method with ultraviolet detection has been developed and validated for the analysis of glucosamine (GS) in various dietary supplement formulations and raw materials. Additionally, the proposed method was used for analysis of carisoprodol (CR) found in ternary mixture with paracetamol (PR) and caffeine (CF). The linearity range...

The aim of this triple-blind full-randomized clinical trial was to quantify analgesia in masticatory muscles and temporomandibular joints after occlusal splint therapy associated with the adjuvant administration of nonsteroidal anti-inflammatory drugs (NSAID) isolated or associated with other therapeutic agents. Pain relief was also recorded. Eighteen volunteers who had been suffering from chro...

Ultraviolet-h igh performance liquid chromatographic (UV-HPLC) method was developed for the quantitation of carisoprodol and its impurities viz 2-methyl-2-propylpropane-1, 3-diyl d icarbamate (impurity-D) and N-isopropyl -2-methyl-2-propyl-3-hydroxy propyl carbamate (impurity-B) in active pharmaceutical ingredient. Validation of the method showed excellent sensitivity, selectivity, accuracy, pr...

The aim of the study was to determine drug concentration ratios between oral fluid collected with the Intercept device and whole blood. Samples of blood and oral fluid were obtained from patients admitted to acute psychiatric treatment and drivers suspected of drugged driving. Samples were analyzed for illegal drugs, benzodiazepines, opioids, carisoprodol, and meprobamate. Drugs were detected i...

Objective: To evaluate the efficacy and safety of the combination of diclofenac, paracetamol, carisoprodol, and caffeine in the treatment of acute low back pain and lumboischialgia, compared to the efficacy and safety of cyclobenzaprine. Study design: Single-center, comparative, randomized, double-blind clinical trial. Method: Drugs were administered t.i.d. for a period of 7 days. Study populat...
