VALPROATE SEMISODIUM Meaning and
Definition
-
Valproate semisodium is a pharmaceutical drug that belongs to the class of anticonvulsant medications. It is primarily used in the treatment of epilepsy, particularly in preventing or managing certain types of seizures. Valproate semisodium is chemically known as sodium valproate semisodium or sodium valproate hemisodium.
Valproate semisodium works by increasing the levels of gamma-aminobutyric acid (GABA) in the brain, which is a neurotransmitter that helps to regulate the transmission of nerve signals. By enhancing the inhibitory effect of GABA, the drug helps to reduce the overactivity of electrical signals in the brain that may lead to seizures.
This medication is available in the form of tablets or extended-release tablets to be taken by mouth. The dosage and frequency of valproate semisodium depend on various factors such as the patient's age, weight, response to treatment, and the type of seizure being treated. It is important to strictly follow the prescribed dosage, as sudden discontinuation or changes in dosage may increase the risk of seizures.
While valproate semisodium has proven to be effective in managing seizures, it is associated with certain side effects. Common side effects may include drowsiness, dizziness, nausea, and weight gain. More serious side effects like liver problems, pancreatitis, or low platelet count may occur but are less common. It is crucial for patients to discuss any concerns or side effects with their healthcare provider.
In conclusion, valproate semisodium is an anticonvulsant medication used in the treatment of epilepsy. It works by increasing the levels of GABA in the brain to reduce seizures. Proper dosage and monitoring are essential to ensure efficacy and minimize potential side effects.
Etymology of VALPROATE SEMISODIUM
The word "valproate" is derived from the chemical name of the compound, valeric acid, combined with the suffix "-ate". Valeric acid itself is named after the plant valerian, from which it was first isolated.
The term "semisodium" refers to a salt form of the compound. In this case, it indicates that valproate is combined with sodium, with only a partial replacement of one of the sodium ions in the salt.
Therefore, the term "valproate semisodium" describes a salt form of valproate, combined with sodium. It is the name given to a specific pharmaceutical formulation of the drug.
