Common antibiotic could help stroke patients recover

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age between 18 and 80 years; 2. Patients with acute ischaemic stroke confirmed by CT or MRI; 3. Having received or planning to receive intravenous thrombolysis within 4.5 hours of onset or within an extended window of 4.5-24 hours based on guideline recommendations (The intravenous thrombolytic drugs include: alteplase, tenecteplase, reteplase or recombinant human prourokinase); 4. The study drug can be applied before intravenous thrombolysis or within 2 hours after the initiation of intravenous thrombolysis; 5. 6≤NIHSS≤25, and Ia≤1; 6. Signed informed consent. Exclusion Criteria: 1. mRS score ≥ 2 prior to onset of the current stroke; 2. History of pseudomembranous colitis or antibiotic-associated colitis; 3. Known allergy or intolerance to tetracycline antibiotics or any component of minocycline; 4. Known resistance to other tetracyclines; 5. Use of tetracycline antibiotics within the past 7 days; 6. Presence of a known community-acquired bacterial infection (e.g., pneumonia, urinary tract infection) or any other concurrent infection requiring antibiotic treatment; 7. History of intracranial hemorrhagic disease within the past 3 months, for example, parenchymal hemorrhage, intraventricular hemorrhage, subarachnoid hemorrhage, subdural or epidural hematoma. 8. Malformation, tumor, abscess, or other major non-ischaemic brain diseases (e.g., multiple sclerosis, other intracranial space-occupying lesions) on baseline cranial CT or MRI; 9.

Use of tretinoin, androgen or antiandrogen treatment (e.g., anabolic steroids, spironolactone) within the past 3 months; 13. Pregnant, breastfeeding, or of childbearing potential who are unwilling to use effective contraception throughout the study; 14. Presence of a severe non-cardio-cerebrovascular disease with a life expectancy of less than 6 months; 15. Participation in any other clinical trial within the past 30 days; 16.
