>Isoniazid is associated with pyridoxine (vitamin B6) deficiency because of its similar structure. Isoniazid is also associated with increased excretion of pyridoxine. Pyridoxal phosphate (a derivative of pyridoxine) is required for δ-aminolevulinic acid synthase, the enzyme responsible for the rate-limiting step in heme synthesis. Therefore, isoniazid-induced pyridoxine deficiency causes insufficient heme formation in early red blood cells, leading to sideroblastic anemia
И правда, вызывает дефицит витамина Б6 даже у человека.
>Doxylamine is used medically as doxylamine succinate, the succinate salt of doxylamine, and is available both alone and in combination with pyridoxine (a form of vitamin B6)
Хмм, в нашем донормиле он без витамина, но в зарубежных лекарствах иногда кладут Б6 вместе с доксиламином, а это явно неспроста. Найти бы еще точное подтверждение и сколько его нужно в мг.
