Buxynil 34 is nitrate derivative from benzene compounds and presents a flukicide effect and is commonly used and the one with best spectrum from all the nitrate derivative trematocides. The mechanism of action corresponds to a respiratory metabolism interference of the helminth, blocking the energy production by mitochondrial oxidative phosphorylation. Buxynil 34 impedes to use the oxide-reduction reactions for adenosine triphosphate (ATP) production. After the use of all its energetic reserves the parasites die due to starvation.
Buxynil 34 also causes the scolex detachment of the intestinal mucosa and the proximal proglottid of the cestode. Studies realized with Buxynil 34 demonstrates that effective blood levels are reached after 5 hours of the drug's administration and with maximum peaks after 12 hours, with an activity threshold during 30 days that maximizes its antiparasitic action.
There can be noted that it is associated strongly to the plasmatic proteins favoring its distribution to the tissues and its slow elimination of the organism. The biotransformation occurs in the gastrointestinal tract and liver. The Buxynil 34 and its metabolites are eliminated by faeces through the bile route.
It is suggested that it acts inhibiting the oxidative phosphorylation. It is possible to confirm its effects over Fasciola gigantica in laboratory conditions, after adding 20 mg/ml in vitro, which induces the immediate stop of the muscular contractions, making think that acts as neuromuscular blocker, due to this the parasite dies paralyzed and with energy deficiency.
Buxynil 34 is used by parenteral route because in the rumen would suffer an efficiency reduction; the maximum plasmatic levels are acquired between 30 and 60 minutes and the mean life is 8 days; the excretion occurs through urine during 30 days approximately.
Buxynil 34 is indicated for control of Fasciolosis (larval and adult stage) caused by Fasciola hepatica and F. gigantica; gastrointestinal parasitism caused by Haemonchus spp., Bunostomum spp., Oesophagostomum spp., Oestrus spp. in cattle, sheep, goats and camel, as well as Ancylostoma spp. and Uncinaria spp.in dogs.
Buxynil 34 is developed and tested for its use in cattle, sheep, goats, camel and dogs.
