Research Excerpts

Overview

Morantel does not bind to the canonical ACh binding sites. Dihydro-beta-erythroidine inhibits morantel-evoked currents noncompetitively.

ExcerptReferenceRelevance
"Morantel is a very weak agonist alone, but we show that the classic competitive antagonist dihydro-beta-erythroidine inhibits morantel-evoked currents noncompetitively, indicating that morantel does not bind to the canonical ACh binding sites."( Morantel allosterically enhances channel gating of neuronal nicotinic acetylcholine alpha 3 beta 2 receptors.

Treatment

Morantel treated cattle grew significantly faster than the ivermectin treated group during the period of treatment. Morantel tartrate treatment (8 mg kg-1) was efficient in reducing the gastrointestinal nematode egg output and fenbendazole treatment (15 mg kg/day) was effective in reducing small lungworm larvae faecal output.

Dosage Studied

At therapeutic dosage rates albendazole was 32,5% effective against the adult stage of Ostertagia spp. Eleven lactating cows of various ages, periods of lactation, and known milk production were orally dosed with the bolus formulation of morantel tartrate.
