Terapijska i neuroprotektivna djelotvornost profilakse i primjene protuotrova u lijeÄenju akutnog otrovanja tabunom odnosno somanom s posebnim osvrtom na profilaksu PANPAL-om
A good knowledge of the basic mechanisms of acute toxicity of organophosphorus compounds has lead to the development of specific antidotes able to counteract their acute toxic effects. Unfortunately, there are still some highly toxic organophosphorus compounds, called nerve agents, that are resistant to standard antidotal treatment. Relatively unsatisfactory antidotal treatment of acute poisonings with some nerve agents has prompted studies of pretreatment possibilities that would increase the resistance of organisms exposed to nerve agents. Current protection against nerve agent poisoning is pyridostigmine, but its prophylactic efficacy is rather limited. To increase the effectiveness of pharmacological pretreatment of soman or tabun poisoning, a prophylactic mixture called PANPAL and consisting of pyridostigmine and two anticholinergic drugs ā benactyzine and trihexyphenidyle was developed, produced and introduced into the Czech Army to protect soldiers against nerve agent exposure. This review describes the evaluation of the potency of PANPAL to counteract acute soman or tabun poisoning and to increase the therapeutic and neuroprotective efficacy of current post-exposure antidotal treatment in comparison with pyridostigmine given alone as pretreatment.Uvid u osnovne mehanizme akutnog otrovanja organofosfornim spojevima omoguÄio je razvoj specifiÄnih protuotrova koji su u stanju poniÅ”titi akutno toksiÄno djelovanje otrova. Nažalost joÅ” postoje veoma toksiÄni organofosforni spojevi poznati kao živÄani otrovi, a koji su otporni na lijeÄenje standardnim protuotrovima. Relativno slabi rezultati dosadaÅ”njeg lijeÄenja akutnog otrovanja živÄanim otrovima potaknuli su istraživanje moguÄnosti profilakse koja bi poveÄala otpornost izloženih organizama. Dosada se u te svrhe rabio piridostigmin, ali je njegovo profilaktiÄko djelovanje priliÄno ograniÄeno. Kako bi se poveÄala djelotvornost profilakse protiv trovanja somanom odnosno tabunom, u oružanim snagama ÄeÅ”ke Republike razvijena je kombinirana profilaksa pod nazivom PANPAL, a koja obuhvaÄa piridostigmin i dva antikolinergika, benaktizin i triheksifenidil. Svrha joj je bolje zaÅ”tititi vojnike kod izlaganja živÄanim otrovima. Ovaj pregledni rad opisuje testiranje djelotvornosti PANPAL-a protiv akutnog otrovanja somanom odnosno tabunom te poboljÅ”anje terapijskoga i neuroprotektivnog djelovanja kod akutnog otrovanja tabunom odnosno somanom u odnosu na iskljuÄivu primjenu piridostigmina kao uobiÄajene profilakse kod trovanja živÄanim agensima
