Use of corrected retention indices based on 1-nitroalkane and alkyl arylketone scales for HPLC identification of basic drugs.

Sixteen basic drugs were examined by HPLC (gradient elution in acetonitrile/phosphate buffer, pH 3.2, containing 0.05% nonylamine) with six different ODS-silica columns. The retention indices (RI) were calculated with alkyl arylketone and 1-nitroalkane scales and were subjected to correction, which enabled comparison of results from commercially different column packing materials. The correction procedure was successful for the 1-nitroalkane scale. The scale based on alkyl arylketones was of less use for basic drugs, because some of them eluted earlier than the first reference homologue. This made impossible the proper calculation and correction of RI values for drugs such as cocaine, diphenhydramine, doxepin, and promethazine. The correction procedure of RI values calculated against the series of 1-nitroalkanes is recommended as a method of standardization of HPLC data.

Pesticide-drug interaction in rats.
Fenyvesi G, Botos M, Ivan J.
The possible interactions between a fungicide, thiram, and some drugs acting on the central nervous system were investigated in rats by means of behavioral methods. Potentiation was found after combined treatment with thiram and promethazine, and after thiram and meprobamate. In the case of trihexyphenidyl, an additive interaction was observed. It is presumed that these observations will be of practical toxicological significance.

Does promethazine (Atosil) influence the human's early acoustically evoked potentials in the same way as the late potential N1?
Zollner C, Karnahl T, Stange G.
In a former investigation the effect of promethazine (Atosil) on the late acoustically evoked potential component N1 was examined. Now the cochlear and the brain-stem potentials were registered by the earlobe-vertex pick-up with i.m. application of 0.8 mg/kg (body weight) promethazine. There was no influence of promethazine either on the compound action potential (NAP) or on the brain-stem potentials (Pot. II-V), but sedation improves significantly the signal-to-noise ratio, therefore we sedate all patients when registering the five early acoustically evoked potentials.
