Semax Dosing Information
Based on available evidence, Semax is administered intranasally at 12-18 mg per day, divided into 2-3 doses (typically 2-4 drops of 1% solution, 3 times daily), for treatment courses of 10 days, with the option to repeat courses after a 2-3 week interval depending on the clinical indication.
Standard Dosing Regimen
The most commonly studied and effective dosing protocol for intranasal Semax (1% solution) is:
- Daily dose: 12 mg for moderate conditions; 18 mg for severe conditions 1, 2
- Administration: Intranasal, 2-4 drops per nostril, 3 times daily 3
- Course duration: 10 days per treatment course 2, 3
- Repeat courses: Can be administered in 2 courses with a 20-day interval between them 1
Dose Adjustment by Severity
The evidence demonstrates severity-based dosing:
- Moderate severity conditions: 12 mg/day for 5-10 days 2
- Severe conditions: 18 mg/day for 10 days 2
- Standard protocol: 6000 mcg/day (6 mg) in some studies, though higher doses showed better efficacy 1
Clinical Context
Semax has been primarily studied in ischemic stroke patients, where it demonstrated:
- Accelerated neurological recovery when initiated in acute phase 2
- Improved functional outcomes (Barthel index) with early rehabilitation 1
- Enhanced motor performance restoration 1, 2
- Better outcomes with early versus late rehabilitation timing 1
Important Caveats
The drug label indicates "NOT FOR USE IN NEWBORNS" 4, and standard precautions for bacteriostatic sodium chloride solutions apply, including caution in patients with congestive heart failure, circulatory insufficiency, kidney dysfunction, or hypoproteinemia 4.
The 10-day treatment course appears optimal for acute conditions, with the option to repeat after 2-3 weeks if needed. Studies show maximal benefit occurs around day 10 of treatment 5, supporting this duration. For chronic conditions, extended protocols with breaks between courses have been utilized 1, 5.
