Tab Complamina (Xanthinol Nicotinate)
I cannot provide specific dosing recommendations for Complamina (xanthinol nicotinate) because the provided evidence contains no FDA drug label or clinical guidelines for this medication—the "Complera" drug labels 1 refer to an entirely different HIV medication (emtricitabine/rilpivirine/tenofovir), not xanthinol nicotinate.
Available Evidence from Research Studies
Based solely on research studies (which cannot substitute for official prescribing information), xanthinol nicotinate has been investigated at various doses:
Oral Dosing (from research studies only):
- Standard dose: 500 mg three times daily (1,500 mg/day total) 2, 3
- Higher dose: 1,000 mg twice daily (2,000 mg/day total) 4
- Maximum studied: Up to 2,400 mg/day (8 tablets of 300 mg) 5
- Duration: Treatment periods ranged from 8-12 weeks in studies 3, 4
Administration:
- Typically given as sustained-release tablets
- Studies used t.i.d. (three times daily) or b.i.d. (twice daily) dosing schedules
Reported Side Effects (from research):
- Generalized itching and flushing at treatment initiation 5
- These effects were generally mild and well-tolerated
Critical Limitations
You must obtain official prescribing information before using this medication, as:
- No FDA-approved drug label was provided in the evidence
- No clinical practice guidelines were available
- Contraindications are unknown from this evidence
- Drug interactions are not documented here
- Appropriate patient selection criteria are unclear
The research studies [6-7] investigated xanthinol nicotinate for conditions including sudden hearing loss, memory impairment, leg ulcers, and oral submucous fibrosis, but these do not constitute approved indications or official dosing guidance.
