Title: Hexobarbital freeze-dried ampoules - contain hexobarbital sodium lyophilisate produced by freeze drying its aq. soln.
Inventor: RUPP ROLAND DR
IPC: A61K31/515
Filed: 1977-07-16
Abstract: New stable hexobarbital sodium medicinal preparations contain the active substance in ampoules in solid form and in accurate dosage. In the prodn. of sterile hexobarbital sodium medicinal preparations, an aq. soln. of hexobarbital sodium is filled into ampoules, and the soln. is freeze-dried after freezing while rotating in a horizontal position in a cold-bath. Use of an aq. soln. of hexobarbital sodium avoids the instability that occurs if organic solns. are used. Freeze-drying by the Shelling method (i.e. freezing while rotating the ampoule in a horizontal position) prevents foaming of the soln.
