Levaveto 75%
Levaveto 75% Uses, Dosage, Side Effects, Food Interaction and all others data.
Levaveto 75% is the active laevo-isomer of tetramisole. It works by paralysing susceptible intestinal worms which are then excreted from the intestines. Levaveto 75% also enhances cellular immune responses in humans.
Levaveto 75% is a synthetic imidazothiazole derivative that has been widely used in treatment of worm infestations in both humans and animals. As an anthelmintic, it probably works by targeting the nematode nicotinergic acetylcholine receptor. As an immunomodulator, it appears that Levaveto 75% is an immunostimulant which has been shown to increase NK cells and activated T-cells in patients receiving this adjuvantly along with 5FU for Stage III colon cancer.

Uses
Levaveto 75% is a fast acting drug which acts on nematode nerve ganglia paralysing the worm’s musculature within seconds of contact. Unable to maintain their position, the worms are then ejected by normal peristaltic movement, usually within 24 hours of levamisole administration. Although it is certain that levamisole primarily influences the neuromuscular system of nematodes, it is possible that in some helminthes the inhibition of the fumarate reductase system contributes to the anthelmintic efficacy of levamisole. Levaveto 75% is used for the treatment of infections by the following gastrointestinal wormspecies:
- Ascaris lumbricoides: Roundworm
- Necator americanus: Hookworm
- Ancylostoma duodenal: Hookworm
- E nterobius vermicularis: Pinworm
- Trichuris trichuria: Whipworm
- Strongyloides stercoralis: Threadworm
- Trichostrongylus colubriformis
Levaveto 75% is also used to associated treatment for these conditions: Adenocarcinoma of Colon, Ancylostoma duodenale infection, Ascaris lumbricoides infection, Carcinoma, Colorectal, Enterobius vermicularis infection, Necatoriasis due to necator americanus, Strongyloides Stercoralis Infection, Trichuris Infection
How Levaveto 75% works
The mechanism of action of levamisole as an antiparasitic agent appears to be tied to its agnositic activity towards the L-subtype nicotinic acetylcholine receptors in nematode muscles. This agonistic action reduces the capacity of the males to control their reproductive muscles and limits their ability to copulate. The mechanism of action of Levaveto 75% as an anticancer drug in combination with fluorouracil is unknown. The effects of levamisole on the immune system are complex. The drug appears to restore depressed immune function rather than to stimulate response to above-normal levels. Levaveto 75% can stimulate formation of antibodies to various antigens, enhance T-cell responses by stimulating T-cell activation and proliferation, potentiate monocyte and macrophage functions including phagocytosis and chemotaxis, and increase neutrophil mobility, adherence, and chemotaxis.
Dosage
Levaveto 75% dosage
The following doses of Levaveto 75% are given as a single administration, preferably after a light meal.
- Age 1-4 year: 1 Tablets or5 mlSyrup
- Age 5-15 year: 2 Tablets or10 mlSyrup
- Age 16year and over: 3 Tablets or 15 mlSyrup
In cases of severe hookworm infection it is suggested that a second standard dose be given one or seven days after the first, whichever timing is feasible.
Side Effects
Side-effects are infrequent. They are usually mild and transient and include nausea, vomiting, abdominal pain, giddiness(dizziness) and headache. An encephalopathylike syndrome has been reported to have occurred in a few patients two or three weeks after treatment.
Toxicity
LD50 = 40 mg/kg (Pigs, subcutaneous); LD50 = 180 mg/kg (rat, oral)
Precaution
Effect on ability to drive or operate machinery: There is no evidence to suggest that Levaveto 75% , used for anthelmintic purpose, will produce sedation. Mild and transient giddiness is an infrequent side-effect of treatment. No precautions are suggested concerning the ability to drive or operate machinery.
In case of concurrent microfilaraemia transient fever may occur.
Interaction
May increase toxicity of phenytoin. Increases bioavailability of ivermectin; decreases bioavailability of albendazole. Alcohol causes disulfiram-like reaction.
Food Interaction
- Take on an empty stomach.
Levaveto 75% Alcohol interaction
[Moderate] GENERALLY AVOID:
Case histories have suggested that levamisole is associated with some side effects (including headache, fever, shivers, and dizziness) that suggest an disulfiram-like interaction with alcohol.
These side effects could be alleviated by total abstinence from alcohol.
No mechanism has been established for this interaction.
Patients receiving levamisole should avoid alcohol.
