💬In plain words
What the trial is, and whether it could suit you
The goal of this clinical trial is to learn if Zhixuan Analgesic Tablet works to treat frequent episodic tension-type headache in adults aged 18-60 years. It will also learn about the safety of Zhixuan Analgesic Tablet.
The main questions it aims to answer are:
* Does Zhixuan Analgesic Tablet reduce the number of headache days compared with placebo within each 4-week interval during the 12-week treatment period?
* What medical problems do participants have when taking Zhixuan Analgesic Tablet? Researchers will compare Zhixuan Analgesic Tablet (4 tablets per dose, 3 times per day) to a matching placebo (a look-alike tablet that contains no active drug) to see if Zhixuan Analgesic Tablet reduces overall headache burden - including headache days, the amount of acute analgesic medication needed, the duration and severity of headaches, and the impact of headache on daily life.
