Biological Activity
| ln Vivo |
A single oral dose of Albendazole at 2.5–10 mg/kg in naturally or artificially infected sheep and cattle eliminated 94–100% of gastrointestinal nematodes (Haemonchus, Ostertagia, Trichostrongylus in abomasum; Strongyloides, Nematodirus, Cooperia, Bunostomum, Trichostrongylus, Capillaria, Oesophagostomum, Chabertia in intestines) and reduced Trichuris by 85% at 10 mg/kg. A single oral dose of 5 mg/kg in sheep and cattle artificially infected with lung nematodes (Dictyocaulus) eliminated 84–100% of the worms. A single oral dose of 10 mg/kg in sheep naturally infected with tapeworms (Moniezia) reduced the worm burden by 100%. A single oral dose of 10 mg/kg in sheep artificially infected with Fasciola hepatica metacercariae eliminated 99% of the liver flukes. Preliminary experiments indicated comparable low doses were effective against various helminths in pigs, horses, and chickens. In mice prophylactically fed Albendazole at 0.05% of the diet for 11 days after oral infection with Ascaris suum ova, the drug protected against the lethal effects of migrating larvae. In dogs, a single oral dose of 250 mg/kg was extremely active against Toxocara canis but only slightly active against Ancylostoma caninum. Administration at 50 mg/kg for 3 days was fully effective against both worms. [1] |
| Animal Protocol |
Sheep and cattle, naturally or artificially infected with various helminths, were given a single oral dose of Albendazole suspended in an unspecified vehicle at doses ranging from 2.5 to 10 mg/kg for gastrointestinal nematodes, 5 mg/kg for lung nematodes (Dictyocaulus), and 10 mg/kg for tapeworms (Moniezia) and liver flukes (Fasciola hepatica). Sheep artificially infected with Fasciola hepatica metacercariae were treated with a single oral dose of 10 mg/kg after the infection became patent. Mice were orally infected with 50,000 embryonated Ascaris suum ova per day for 2 days and then fed a diet containing 0.05% Albendazole for 11 days prophylactically. Dogs were given a single oral dose of 250 mg/kg or 50 mg/kg/day for 3 days for evaluation against Toxocara canis and Ancylostoma caninum. Efficacy was assessed by worm count reduction at necropsy.

| Toxicity/Toxicokinetics |
The oral LD50 of Albendazole in rats was determined to be 2.40 g/kg (95% confidence limits: 1.55 to 3.25 g/kg). No untoward effects were observed in sheep dosed orally with up to 100 mg/kg. A single dose of 500 mg/kg was not tolerated in sheep. Studies on the toxic and teratogenic potential of the compound were stated to be underway. [1] |

| Additional Infomation |
Albendazole is a new derivative of the benzimidazole group of anthelmintics, chemically described as methyl [5-(propylthio)-1H-benzimidazol-2-yl]carbamate. It is a stable, white, odorless powder melting at 214–215°C with decomposition. It is insoluble in water and only slightly soluble in most organic solvents. It was reported as the first anthelmintic with promising useful activity against all major types of helminth parasites (nematodes, cestodes, trematodes) threatening domestic animals. [1] |
Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.
