This study used the United States Forces Korea Prescription form (Annex A-Over-The-Counter Prescription) and Alice Rich’s Pain scale with robax platinum, robaxacet including narproxen. The IBM SPSS statics version 24 was used to calculate the data. The combined methocarbamol 500 mg, acetaminophen 325 mg tablet, and ibuprofen 200 mg (or naproxen) tablet can work as well as the combined methocarbamol 500 mg tablet with acetaminophen 325 mg tablet with stretches. Both methods were successful in managing pain. The drug combination of methocarbamol 500 mg, acetaminophen 325 mg and Corresponding author: Seung-Min Yeom ibuprofen 200 mg tablets yielded similar benefits as the methocarbamol 500 mg and USFK, Army 2nd Infantry Division, Camp Hovey acetaminophen 325 mg tablets paired with physical stretching exercises regarding managing Combined Troops Medical Aid Station, 2557 Pyeonghwa-ro, Dongducheon 11311, Korea overall pain.

As part of personalized medicine, such as military service members are directly exposed to targeted treatment is necessary as one of the important musculoskeletal disorders. In case of muscle pain, the ways to alleviate pain. To avoid overdose and prevent each more various pains occur, the more personalized medicine toxicity, various types of pain treatments such as www.kjcls.org Korean J Clin Lab Sci.

If the dose-dependent perturbations in urinary metabolite patients take amount of over the counter, they could concentrations caused by naproxen toxicity. These were possibly be overdosage. As part of targeted treatment, the investigated by using 1H NMR spectroscopy coupled with following results are considered to be one of the important multivariate statistical analysis [3].

The resultant metabolic NMR test, each 600-MHz spectrum represents one time profiles demonstrate that the naproxen-induced gastric point after dosing for each toxic compound [1]. It can damage exhibited energy metabolism perturbations that show the toxicity on xenobiotics relatively affect specific elevated their urinary levels of citrate, cis–aconitate, regions within the organs (depicted in the figure by shaded creatine, and creatine phosphate.

Therefore, it’s necessary to treat patients based on treatment is necessary as various types of pain treatments. patient’s underlying diseases. For instance, prescription including stretches can be used In case of another chemical tracking [3], we could see to treat patients are at risk of over dosage. Not only prescribed drugs but also over the counter drugs have to be considered in case of treatment for patients who have a various musculoskeletal pains on individual underlying diseases for a long term. According to previous study about hydrocodone with ibuprofen [7], it can show analgesic combination can be much effective than single analgesic. MATERIALS AND METHODS 1.

Anti-inflammatory drugs can interfere in the pathophysiological process of inflammation, to minimize tissue damage and provide greater comfort to the patient. Therefore, it is important to note that due to the existence of a large number of species available for research, the successful development of new naturally occurring anti-inflammatory drugs depends mainly on a multidisciplinary effort to find new molecules.
