Summary:

anesthesia. Material and Methods. Decahydroquinolinyl derivative under laboratory code PAS-68 synthesized in the A. B. Bekturov Institute of Chemical Sciences under the guidance of K. D. Praliev has been studied. Benzocaine, lido-caine and tetracaine were used as the comparison drugs. Male rabbits of 2,0-3,5 kg weight were used as experimental animals. A threshold of corneal sensitivity to tactile effects (Rainier index) was determined by the standard method. Computer prognosis of PAS-68 acute toxicity also was made. Results. The local anesthetic activity of 1 %, 0,5% and 0,25% solutions of PAS-68 were identified as higher than that for lidocaine and benzocaine in similar concentrations (p <0,05) but lower than that for tetracaine (p<0,05). PAS-68 has no local irritating action. The duration of anesthesia, 0,5% and 1 % PAS 68 exceeds that for benzocaine and lidocaine at equivalent concentrations (p<0,05). By this kind of activity PAS-68 is a second to the duration of anesthesia by tetracaine (p<0,05). The latent period of anesthesia induced by PAS-68 is shorter than the latent periods induced by benzocaine, lidocaine and tetracaine. On the base of predictive analysis it was concluded that PAS-68 is of low toxicity. Conclusion. PAS-68 exceeds benzocaine and lidocaine by the local anesthetic activity and duration of anesthesia and is second only to tetracaine. The latent period of anesthesia PAC-68 is shorter than the latent period of benzocaine, lidocaine and tetracaine respectively.
