shockry parasites Flashcards
5 MOA’s of antiparasitic drugs
- inhibition of NM blockers
- inhibition of nueronal system
- inhibiton of energy metabolism
- damaage membrane integrity
- inhibition of reproduction
competitive NM blockers
piperazine
Depolarizing NM blockers
levamisole
pyrantal

cholinesterase inhibitors
dichlorvos
trichlorfon
Activates G-protein couples R in LAT-1 and LAT-2 at NM junction increase release or inhibitory neuropeptides causing paralysis of somatic muscles and pharngeal pump resulting in death of parasite
emodepside..combo with praziquantail as spot on
inhibition of Neuronal system- bind to GABA and/or glutamate-gated Cl channels which
- increase cl membrane causing flaciid paralysis of somathic muscles
- inhibits egg production of parasite
MACROCYTIC LACTONES
- avermectins
- milbemycins
inhibit enegy metabolism by:
- bind to tubulin of parasite disrupting cell division
- deplete glycogen reserves tue to inhibit fumurate reductase and block mitchondrial function- parasitic death

damage membrane integrity by:
1. release Ca+ from parasite muscle cell storage
- ionic changes
