Phong thap dan tablets are intended to treat low back pain. This study was carried out to evaluate the
analgesic effects of Phong thap dan tablets in experimental animals. The analgesic effects were evaluated in
three animal models: hot plate, mechanical stimulation and acetic acid-induced writhing test. Mice were divided
into 4 groups given oral water, control drug (codein phosphate in hot plate and mechanical stimulation tests or
aspirin in writhing test), Phong thap dan at 2.88 tablets (1.44 g) or 8.64 tablets (4.32 g)/kg b.w/day, respectively.
Our results showed that Phong thap dan tablets at both doses increased the reaction time to thermal stimulation,
increased the ...
