Minocycline has been found to reduce cerebral edema secondary to cerebral hemorrhage, promote hematoma absorption, and shorten hematoma absorption time; clinical studies have been conducted to confirm the safety in the treatment, but no significant hematoma absorption effect was seen with short duration of drug use. Therefore, the investigators propose to conduct a multicenter randomized controlled clinical trial to determine its accelerating effect on hematoma absorption.

There is a significant increase in the incidence of spontaneous intracerebral hemorrhage, combined with a high mortality rate. Surgical treatment is mainly used to remove intracerebral hematoma with a supratentorial volume greater than 20ml, and most intracerebral hematomas below 20mL are left to absorb on their own, and the absorption time of such hematomas is about 4 to 6 weeks. Minocycline is a tetracycline antibiotic routinely used in clinical practice for the treatment of bacterial infection and acne.

It has been found that it can not only reduce iron overload after intracerebral hemorrhage and inhibit neuroinflammation, but also reduce secondary cerebral edema. Some animal experiments have confirmed that it can promote hematoma absorption through iron chelation and shorten hematoma absorption time; clinical studies have been conducted to confirm the safety in the treatment of intracerebral hemorrhage, but no significant effect has been seen with short duration of drug use. No clinical RCT study has been conducted to confirm its accelerating effect on the absorption of adult intracerebral hematoma. Therefore, the investigators propose to conduct a multicenter randomized controlled clinical trial to determine its accelerating effect on hematoma absorption, and this study will have important clinical practical value.
