Albendazole


A benzimidazole broad-spectrum anthelmintic structurally related to mebendazole that is effective against many diseases. Albendazole is an anthelmintic (an-thel-MIN-tik) or anti- worm medication. It prevents newly hatched insect larvae (worms) from growing or multiplying in your body. Albendazole is used to treat certain infections caused by worms such as pork tapeworm and dog tapeworm

Albendazole should not be used during pregnancy, unless there is no alternate treatment. You may need to have a negative pregnancy test before starting this treatment.

Indication
For the treatment of parenchymal neurocysticercosis due to active lesions caused by larval forms of the pork tapeworm, Taenia solium and for the treatment of cystic hydatid disease of the liver, lung, and peritoneum, caused by the larval form of the dog tapeworm, Echinococcus granulosus

    How to use Albendazole

    Take this medication by mouth with meals as directed by your doctor, usually 1 to 2 times daily. If you or your child have trouble swallowing tablets, you may crush or chew your dose and take it with water.

    For some conditions (such as hydatid disease), your doctor may direct you to take this medication in a treatment cycle (for example, twice daily with meals for 28 days then stopping the medication for 2 weeks). Carefully follow your doctor's instructions.

    Mechanism of action
    Albendazole causes degenerative alterations in the tegument and intestinal cells of the worm by binding to the colchicine-sensitive site of tubulin, thus inhibiting its polymerization or assembly into microtubules. 

    The loss of the cytoplasmic microtubules leads to impaired uptake of glucose by the larval and adult stages of the susceptible parasites, and depletes their glycogen stores.

    Degenerative changes in the endoplasmic reticulum, the mitochondria of the germinal layer, and the subsequent release of lysosomes result in decreased production of adenosine triphosphate (ATP), which is the energy required for the survival of the helminth. Due to diminished energy production, the parasite is immobilized and eventually dies.

    Albendazole side effects
    Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
    Call your doctor at once if you have:
    • signs of bone marrow suppression--sudden weakness or ill feeling, fever, chills, sore throat, mouth sores, red or swollen gums, trouble swallowing, easy bruising or bleeding; or
    • liver problems--nausea, upper stomach pain, itching, tired feeling, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).
    Common side effects may include:
    • stomach pain, nausea, vomiting;
    • dizziness, spinning sensation;
    • headache; or
    • temporary hair loss.
