Storage/Stability/Compatibility - Morantel tartrate products should be stored at room temperature (15-30°C) unless otherwise instructed by the manufacturer.
Pharmacology - Like pyrantel, morantel acts as depolarizing neuromuscular blocking agent in susceptible parasites, thereby paralyzing the organism. The drug possesses nicotine-like properties and acts similarly to acetylcholine. Morantel also inhibits fumarate reductase in Haemonchus spp.. Morantel is slower than pyrantel in its onset of action, but is approximately 100 times as potent.
Pharmacokinetics - After oral administration, morantel is absorbed rapidly from the upper abomasum and small intestine. Peak levels occur about 4-6 hours after dosing. The drug is promptly metabolized in the liver. Within 96 hours of administration, 17% of the drug is excreted in the urine and the remainder in the feces.
Contraindications/Precautions - There are no absolute contraindications to using this drug. The sustained-release oral cartridges (Paratect®) are not to be used in cattle weighing less than 90 kg. Morantel is considered to be generally safe to use during pregnancy.
Adverse Effects/Warnings - At recommended doses, adverse effects are not commonly seen. For more information, see Overdosage section below.
Overdosage/Acute Toxicity - Morantel tartrate has a large safety margin. In cattle, dosages of up to 200 mg/kg (20 times recommended dose) resulted in no toxic reactions. The LD50 in mice is 5 g/kg. Symptoms of toxicity that might possibly be seen include increased respiratory rates, profuse sweating (in animals able to do so), ataxia or other cholinergic effects.
Chronic toxicity studies have been conducted in cattle and sheep. Doses of 4 times recommended were given to sheep with no detectable deleterious effects. Cattle receiving 2.5 times recommended dose for 2 weeks showed no toxic signs.
Drug Interactions - Paratect® cartridges should not be administered with mineral bullets as decreased anthelmintic efficacy can result. Because of similar mechanisms of action (and toxicity), morantel is recommended not to be used concurrently with pyrantel or levamisole. Observation for adverse effects should be intensified if used concomitantly with an organophosphate or diethylcarbamazine. Piperazine and morantel have antagonistic mechanisms of action; do not use together. Do not add to feeds containing bentonite.
