Abstract:
OBJECTIVETo observe the clinical effect of Lingtong Capsule (LC) in treating primary dysmenorrhea (PD).
METHODSTotally 59 PD patients took LC, while 59 patients in the placebo group took placebo capsule, two pills immediately when they felt dysmenorrhea. Their pain levels were quantitatively classified. The pain score was assessed at an interval of 30 min using visual analogue scale/score (VAS) while taking medicine and within two h after taking medicine. It was assessed as effective when the pain level was reduced by more than or equal to 50% within 2 h.
RESULTSThe total effective rate was 69.49% (41/ 59) in the LC group and 20.34% (12/59) in the placebo group (P < 0.01). The analgesia effect was obviously superior in the LC group 60 min after taking medicine (P < 0.01). LC showed better effect in treating mild, moderate, and severe PD (P < 0.05).
CONCLUSIONLC showed obvious analgesia effect on PD.
