Barbamil (amital-natriy)

Barbamil uyqu chaqiruvchi hisoblanib, katta dozada narkoz chaqiradi. Preparat tinchlantiruvchi va tutkanoqqa qarshi qo‘llaniladi. Poroshok va tabletka xolida chiqarilib, "bromital» va "barbafen" tabletkasi tarkibiga kiradi. Organizmga tushgan barbituratni 45% metabolizmga uchrab o‘zgaradi.

Sifat reaksiyasi
Barbamil izopropilamin va kobalt tuzlari bilan binafsha rang hosil qiladi.
