At a glance
Thiamine Hydrochloride (Vitamin B1) is an essential water-soluble vitamin used for beriberi, Wernicke's encephalopathy, pregnancy-associated neuritis, and pellagra.
Indications
- Beriberi
- Wernicke's encephalopathy
- Pregnancy-associated neuritis
- Pellagra
- Thiamine deficiency (poor dietary intake, impaired GI absorption, pregnancy, high-carbohydrate diet)
Pharmacology
Thiamine Hydrochloride is absorbed from the GI tract and distributed to most body tissues, with excess excreted in urine. It is converted to thiamine pyrophosphate (TPP), an essential coenzyme in carbohydrate and amino acid metabolism. TPP is vital for pyruvic acid decarboxylation and the citric acid cycle.
Dosage
Adult Dose (Oral/Parenteral):
- Mild chronic deficiency: 10-25 mg/day (single or divided)
- Thiamine deficiency: 100-300 mg/day
- Wernicke-Korsakoff syndrome: Initially 100 mg slow IV over 10 min; then 50-100 mg/day IM/IV until oral intake possible
Pediatric Dose (Oral/Parenteral):
- Thiamine deficiency: 10-50 mg/day (divided)
- Beriberi: 10-25 mg IV/IM/day (critically ill) or 10-50 mg/dose PO/day for ≥2 weeks, then 5-10 mg/day PO for 1 month
