Mehanizem delovanja

[uredi | uredi kodo]

Glede na mehanizem delovanja jih lahko razdelimo na:[1][2]

  • fizikalna protisredstva – delujejo kot adsorbent in pospešijo odstranitev neabsorbiranih škodljivih snovi iz prebavil (npr. aktivno oglje)
  • fiziološka protisredstva
  • kemična protisredstva – tvorijo s strupom inertno obliko spojine oziroma komplekse strup-protisredtvo, ki se nepresnovljeni izločajo iz organizma (npr. kelatorji težkih kovin: dimerkaprol, dinatrij-kalcijev EDTA ali deferoksamin)
