  • Objectives : The aim of this study is to evaluate the efficacy of a topical herbal gel application for the treatment of chronic shoulder pain. Methods : We compared the effects of Dapureo gel, which contains several herbal medicines known to improve shoulder pain, with those of placebo gel by double-blind method. 30 participants were randomized - 15 were assigned to treatment group and the other 15 were assigned to control group. Either Dapureo gel(treatment group) or placebo gel(control group) was applied topically by themselves, once a day for 2 weeks. Primary outcome was daily visual analogue scale(VAS) changes for shoulder pain which was self-reported for 2 weeks. Secondary outcome was the difference in the total shoulder pain and disability index(SPADI) which was measured at a baseline and 2 weeks after the treatment. Results : Primary outcome: Subjects of treatment group showed statistically significant improvement in VAS compared to control subjects continuously from the second day(p <0.05) to the fifteenth day(p <0.001). The treatment group showed 31% of pain reduction on the fifteenth day, while the control group showed only 7%. Secondary outcome: In terms of SPADI changes, the treatment group showed improvement compared to the control group(p <0.01). Conclusions : These results suggest that the topical herbal gel treatment used in this study is effective in improving chronic shoulder pain.

  • The present study was aimed at preparing microemulsion-based hydrogel (MBH) for the skin delivery of itraconazole. Microemulsion prepared with Transcutol as a surfactant, benzyl alcohol as an oil and the mixture of ethanol and phasphatidyl choline (3:2) as a cosurfactant were characterized by solubility, phase diagram, particle size. MBHs were prepared using 0.7 % of xanthan gum (F1-1) or carbopol 940 (F1-2) as gelling agents and characterized by viscosity studies. The in vitro permeation data obtained by using the Franz diffusion cells and hairless mouse skin showed that the optimized microemulsion (F1) consisting of itraconazole (1% w/w), benzyl alcohol (10% w/w), Transcutol (10% w/w) and the mixture of ethanol and phospahtidylcholine (3:2) (10% w/w) and water (49% w/w) showed significant difference in the flux (${\sim}1{\mu}g/cm^2/h$) with their corresponding MBHs (0.25-0.64 ${\mu}g/cm^2/h$). However, the in vitro skin drug content showed no significant difference between F1 and F1-1, while F1-2 showed significantly low skin drug content. The effect of the amount of drug loading (0.02, 1 and 1.5% w/w) on the optimized MBH (F1-2) showed that the permeation and skin drug content increased with higher drug loading (1.5%). The in vivo study of the optimized MBH (F1-2 with1.5% w/w drug loading) showed that this formulation could be used as a potential topical formulation for itraconazole.

Anti-inflammatory Effects of Hydrogels Containing Piroxicam and Hydrolyzed Products of Scutellariae Radix on Collagen-induced Arthritis (콜라겐으로 유발된 관절염에 대한 피록시캄 및 황금 가수분해물 복합 히드로겔의 항염 효과)

  • In order to access the suppressive effects of piroxicam (PX) and hydrolyzed products of Scutellariae Radix (PSH) on arthritis, we investigated whether PSH gel could suppress the progression of collagen-induced arthritis. PX, one of nonsteroidal anti-inflammatory drugs has been used in the systemic and topical treatment in a variety of inflammatory conditions. Scutellariae Radix, one of the herbal medicines, was used for the purpose of anti-inflammatory and anti-bacterials. For the purpose of transdermal absorption of the hydrogel preparations, two classes of hydrogels (PX, PSH) were formulated with carbomer 940, diethylene glycol monoethyl ether, polyethylene glycol-8-glyceryl caprylate/caprate and triethanolamine. In carrageenan-induced edema in rat hind paws, inhibition of foot swelling was more increased in PSH than PX hydrogel. Rheumatoid factors including serum IgG, IgM and collagen specific antibody were present much lower in PSH gel treated mice than control. Histological examination revealed that PSH hydrogel inhibited infiltration of inflammatory cells into affected paw joint, compared with control. The PSH hydrogel would be a suitable preparation to increase transdermal treatment for anti-inflammatory effects on collagen-induced arthritis.
