New potential antihypoxants based on 2-ethyl-3-(N,N-dimethylcarbamoyloxy)-6-methylpyridine

It is established that succinic acid is capable of potentiating (synergism) the antihypoxic activity of 3-hydroxypyridine derivatives such as the succinate (Ia) and hydrochloride (Ib) of 3-( N , N -dimethylcarbamoyloxy)- 2-ethyl-6-methylpyridine. This effect makes it expedient to create new drugs containing a mixture of Ia or Ib and succinic acid derivatives that would possess antihypoxic, antiamnestic, and anticonvulsant activity. The antihypoxic activity of 3-hydroxypyridine drugs increases in the order emoxypin
