mobic and Pelvic-Pain

The aim of this study is to explore non-steroid anti-inflammation drugs (NSAIDs) potency for pelvic floor muscle pain by measuring local concentration in a rat model.. We used nine NSAIDs, including nabumetone, naproxen, ibuprofen, meloxicam, piroxicam, diclofenac potassium, etodolac, indomethacin, and sulindac, and 9 groups of female Wister rats. Each group of rats was fed with one kind of NSAID (2 mg/mL) for three consecutive days. Thereafter, one mL of blood and one gram of pelvic floor muscle were taken to measure drug pharmacokinetics, including partition coefficient, lipophilicity, elimination of half-life (T1/2) and muscle/plasma converting ratio (Css, muscle/Css, plasma).. Diclofenac potassium had the lowest T1/2 and the highest mean Css, muscle/Css, plasma (1.9 hours and 0.85±0.53, respectively). The mean Css, muscle/Css, plasma of sulindac, naproxen and ibuprofen were lower than other experimental NSAIDs.. Diclofenac potassium had the highest disposition in pelvic floor muscle in a rat model. The finding implies that diclofenac potassium might be the choice for pain relief in pelvic muscle.
