Trimecaine which we used compounds based on N-ethoxyethylpiperidine, trimecaine and in our research as a parent compound nowadays has been piromecaine, obtained via N-alkylation with alkyl halides. The applied as a local anesthetic and antiarrhythmic and in cardio combination of piperidine ring, secondary amine group, trimecaine and piromecaine in form of a base with different surgery [8], [9]. Piromecaine also shows local anesthetic and alkyl radicals bring to molecule new biological activity and/or antiarrhythmic activity [10], [11]. To define the range of reduce toxic effects of parent compounds. The potential biological activity of new synthesized compounds we used pharmacological activity and potential toxic effects of the Pass online service (Prediction of Activity Spectra for obtained compounds were predicted with PASS online service Substances) [12], which helps to predict biological and (Prediction of Activity Spectra for Substances) showing pharmacological effects, action mechanisms and also toxicity cardiotonic, antiarrhythmic and spasmolytic potential activities.

Local Anaesthetic Infiltration for Peri-Operative Pain Control in Total
Marques et al. BMC Musculoskeletal Disorders 2014, 15:220 http://www.biomedcentral.com/1471-2474/15/220 RESEARCH ARTICLE Open Access Local anaesthetic infiltration for peri-operative pain control in total hip and knee replacement: systematic review and meta-analyses of short- and long-term effectiveness Elsa MR Marques1*, Hayley E Jones1, Karen T Elvers2, Mark Pyke3, Ashley W Blom2 and Andrew D Beswick2 Abstract Background: Surgical pain is managed with multi-modal anaesthesia in total hip replacement (THR) and total knee replacement (TKR). It is unclear whether including local anaesthetic infiltration before wound closure provides additional pain control. Methods: We performed a systematic review of randomised controlled trials of local anaesthetic infiltration in patients receiving THR or TKR. We searched MEDLINE, Embase and Cochrane CENTRAL to December 2012. Two reviewers screened abstracts, extracted data, and contacted authors for unpublished outcomes and data. Outcomes collected were post-operative pain at rest and during activity after 24 and 48 hours, opioid requirement, mobilisation, hospital stay and complications. When feasible, we estimated pooled treatment effects using random effects meta-analyses. Results: In 13 studies including 909 patients undergoing THR, patients receiving local anaesthetic infiltration experienced a greater reduction in pain at 24 hours at rest by standardised mean difference (SMD) −0.61 (95% CI −1.05, −0.16; p = 0.008) and by SMD −0.43 (95% CI −0.78 −0.09; p = 0.014) at 48 hours during activity. In TKR, diverse multi-modal regimens were reported. In 23 studies including 1439 patients undergoing TKR, local anaesthetic infiltration reduced pain on average by SMD −0.40 (95% CI −0.58, −0.22; p < 0.001) at 24 hours at rest and by SMD −0.27 (95% CI −0.50, −0.05; p = 0.018) at 48 hours during activity, compared with patients receiving no infiltration or placebo. -

Most of the compounds demonstrated surface anaesthetic activity higher than that of lidocaine, ropivacaine and bupivacaine. We established that the local anaesthetic activity was sensitive to structural variations in the substitution pattern at the aromatic ring and the type of alkyl group at the proline nitrogen atom. -

Comparison of Effects of Selected Local Anesthetics on Sodium and Potassium Channels in Mammalian Neuron
Gen. Physiol. Biophys. (1988), 7,177—189 177 Comparison of Effects of Selected Local Anesthetics on Sodium and Potassium Channels in Mammalian Neuron S. ŠTOLC Institute of Experimental Pharmacology, Centre of Physiological Sciences, Slovak Academy of Sciences, 842 16 Bratislava, Czechoslovakia Abstract. Effects of procaine, trimecaine, and a new carbanilate local anesthetic, carbizocaine, on early sodium inward current and fast and slow components of potassium outward current in the membrane of the rat dorsal root ganglion neuron were studied using the internal dialysis and potential clamp techniques. All the currents studied were depressed in the presence of the drugs tested. However, for inhibition of the inward current concentrations lower by ap proximately one to more than two orders were sufficient compared to those required for similar inhibition of the outward currents. Carbizocaine was the most effective, procaine the least effective drug. Almost identical ratios of the negative logarithms of mean effective concentrations for blocking the inward and the outward current respectively, were found for each of the drugs tested. None of the drugs could be characterized as a specific blocker of sodium or potassium channels. It is concluded that the mechanisms of action of these three local anesthetics in all the three types of ion channels studied in the neuronal membrane are very similar regardless of both the type of the chemical bond in the intermediary chain of the molecules (ester, anilide, carbanilate) and the structure of the aromatic moiety, or the absolute potency of the drug. Key words: Local anesthetics — Sodium ion channels — Potassium ion channels — Potential clamp technique — Isolated neuron dialysis Introduction It is generally accepted that the block of conduction of action potential in excitable cells elicited by common local anesthetics is mainly due to inhibition of activation of sodium channels (Shanes 1958; Strichartz 1976; Covino and The paper is dedicated to Prof.
