Mannich bases of albendazole
Mannich bases of albendazole and fenbendazole were prepared by Dhaneshwar et al., Indian drugs, 28(1), 24-26, 1990, using various secondary amines such as dimethylamine, dipropylamine, pyrrolidine, piperazine, etc. Further Mannich bases are described in Garst et al. (U.S. Pat. No. 6,093,734). However, actual activity has not been demonstrated for the Mannich bases, and these derivative show very low stability in water.
A water soluble prodrug of albendazole manufacturer exists, namely netobimin. But although netobimin is water soluble, it has been reported to cause embryonal toxicity.
In WO9312124 another class of benzimidazoles is discussed, namely substituted 2-[[(3,4-dialkoxy-2-pyridinyl)-methyl]sulfonyl]-1(H)-benzimi dazole-1-yl compounds. These benzimidazoles are gastric acid secretion inhibitors (proton pump inhibitors) and structurally resemble well-known gastric acid secretion inhibitors like omeprazole and lansoprazole. In contrast to the benzimidazole carbamates, which are practically insoluble in water, the benzimidazole proton pump inhibitors are markedly more soluble in water. For example, omeprazole has a solubility of 500 μg/mL Unfortunately, there are a number of side effects associated with using albendazole. Some of these side effects include nausea, stomach pain, vomiting, temporary hair loss, dizziness, headache, unusual weakness, easy bruising and bleeding, sore throat, fever, skin rash, body aches, flu-like symptoms and severe skin blistering. While these are considered the most common side effects associated with this drug, they only affect a small amount of users.
If you are allergic to albendazole or mebendazole, you should not use this medication as it can cause severe internal damage to some users. This medication has been known to lower the body's ability to fight infection and it is recommended that users stay away from anyone with an illness or disease until they have completed treatment. Regular blood tests will be required to ensure that your blood-cell levels remain at a healthy level throughout the course of your treatment, so consult with your doctor about an appropriate schedule.The compounds of the invention are highly soluble and stable in water. For example, a mixture of (5- and 6-phenylsulfanyl-1-phosphonooxymethyl-1(H)-benzoimidazol-2-y l)-carbamic acid methyl esters di-sodium salts has a solubility in water of 132 mM (67 g/L). Furthermore, other compounds according to the invention such as N-phosphonooxymethyl substituted albendazole, mebendazole, flubendazole and luxabendazole sodium salts have aqueous solubilities of at least 50 mM.
Always use albendazole tablets exactly as it was prescribed by your doctor and never in dosages larger than what has been recommended on the label. The medication is administered in tablet form and should be taken with food and a full glass of water. Alebendazole is sometimes used as a cycled medication, meaning that treatment may occur for four weeks followed directly by two weeks of non-treatment. Store this medication away from sources of moisture and at room temperature for the best results.If you experience any of the above side effects, contact your doctor immediately.
If an overdose is suspected, contact the poison control center at (800) 222-1222 and head directly to the nearest emergency room.
Albendazole is meant in the treatment of the above ailments only and should not be used for any other medical purpose unless specifically prescribed by a doctor.
