Ibuprofen, non-steroidal anti-inflammatory drugs; NSAIDs, is a highly crystalline substance with the pharmaceutical properties of poor solubility and low bioavailability. The size reduction of ibuprofen is needed to improve the solubility. The objective of this study is to optimize the grinding condition of ibuprofen. Grinding of ibuprofen was carried out using a planetary mill. Grinding parameters were optimized using Box-Behnken experimental design method. The physical characteristics of ground ibuprofen were investigated for the particle size by particle size analyzer, for the crystal size by X-ray diffraction (XRD), and for the tensile strength by tensile/compression tester. The optimum conditions for the milling of ibuprofen were 290 rpm of the revolution number of mill, 24.6 g of the weight of sample, and 10 minutes of grinding time. The measured value of the particle size of ground ibuprofen at these optimum conditions was $13.5{\mu}m$. The results showed that the crystal size of ibuprofen was reduced by the planetary milling process. In case the relative density of the tablets formulated of ground ibuprofen was range of 0.85~0.90, the tensile strength of them was range of 1$2{\sim}14Kg_f/cm^2$.

Plantaginis seed has been applied in Chinese medicine a as well as in folk remedy. It was advocated that Plantaginis S Semeη exerts good therapeutic effects as anti-inflammatory, antitussive, obstipant and diuretic agent in some cases of alimentary, respiratory a and renal disorders. This study was carried out in order to r re-evaluate the pharmacological action, especially the hypotensive a action of Plantaginis Semen and to elucidate the mechanism of its a action, making use of Plantaginis Semen methanol extract (PME), because its basic pharmacological action, i. e., hypotensive action is n not clear. 1) PME, when administered into intravenous route, elicited the h hypotensive response dependent on the dose of PME given to the rabbit anesthetized with urethane. 2) This hypotensive response of P PME was inhibited by atropine and potentiated by physostigmine, but not influ$\varepsilon$need by vagotomization. 3) Depressor effect of PME was blocked by chlorisondamine, phentolamine, and bethanicline, while not altered by cyproheptadine, diphenhydramine and propran¬olol. 4) The secondary pressor response after blocking the depressor e effect of PME by chlorisondamine was produced, but this pressor response was deminished by atropine. 5) PME augmented the pressor e effect of norepinephrine and angiotensin, on the other hand, reduced b blood pressure elevated by carotid occlusion reflex. 6) These observa¬t tions suggest that PME may induce the hypotensive response via dual mechanisms of parasympathomimetic and sympatholytic action, that the positions of this action are cholinergic peripheral site and sympathetic ganglia respectively, and that PME may possess the pressor activity caused by stimulation of "atropine-sensitive site" which seems to existsin the sympathetic ganglia.

Objectives: This study was performed to investigate the pain relief effect of lower abdomen warmer on primary dysmenorrhea patients taking nonsteroidal anti-inflammatory drugs and whether the using of warmer can supplement or replace the drugs. Methods: 30 women with primary dysmenorrhea were assigned to treatment group (n=15) and control group (n=15). At 1st visit, the treatment group was provided with a wirless multiuse warmer and trained to use at least three times per menstrual cycle. The control group was not provided with the warmer, and both groups were provided with a menstrual diary and instructed to record their pain intensity and dose of analgesic every menstrual period. Visual Analogue Scale (VAS) were used to assess the intensity of overall pain and the most severe pain during the menstrual period. And the total number of analgesic taken during menstruation and the average number of analgesic taken during a single dose were measured. Results: There was significant pain relief in the treatment group compared to before baseline, and there was a significant difference from the control group. In addition, there was no significant difference in the frequency of taking analgesic during the menstrual period between the treatment group and the control group, but the dose of analgesic was significantly lower in the treatment group than in the control group. Conclusions: This clinical trial showed that lower abdomen warmer would helpful in relieving primary dysmenorrhea and could help reduce the use of nonsteroidal anti-inflammatory drugs.

In this paper, we present an approach for detection of adverse drug reactions from drug reviews to compensate limitations of the spontaneous adverse drug reactions reporting system. Considering negative reviews usually contain adverse drug reactions, sentiment analysis on drug reviews was performed and extracted negative reviews. After then, MedDRA dictionary and named entity recognition were applied to the negative reviews to detect adverse drug reactions. For the experiment, drug reviews of Celecoxib, Naproxen, and Ibuprofen from 5 drug review sites, and analyzed. Our results showed that detection of adverse drug reactions is able to compensate to limitation of under-reporting in the spontaneous adverse drugs reactions reporting system.

Objectives: This study was conducted to evaluate the effectiveness of acupuncture in patients with primary menstrual difficulties taking NSAIDs. Methods: 30 women with primary menstrual difficulties with NSAIDs were assigned to treatment groups (n=15) and control groups (n=15). On their first visit, both groups were provided with a menstrual diary and were required to record the intensity of pain and the dosage of painkillers during each menstrual cycle. The treatment group received two acupuncture treatments per cycle during two cycles, and the control group did not receive acupuncture. Pain strength during menstruation was evaluated using Visual Analogue Scale (VAS), and the total number of painkillers taken during menstruation and the average number of painkillers taken during a single dose was measured. Results: The treatment group had significant pain relief compared to the pre-test group and significant differences from the control group. In addition, there was a significant difference between the treatment group and the control group in the frequency of taking painkillers during the menstrual period and the dose in the test group was significantly lower than before treatment. Conclusions: This clinical trial showed that this acupuncture can help alleviate primary menstruation and reduce the use of nonsteroidal anti-inflammatory drugs.
