valproate bismuth

**Valproate bismuth** is a discrete bismuth(III) salt of valproic acid, consisting of one bismuth cation coordinated with three valproate anions. It is also called **bismuth dipropylacetate** and is the medicinal ingredient in the Canadian non-prescription rectal suppository **Neo-Laryngobis**. Neo-Laryngobis contains 135 mg bismuth dipropylacetate per suppository and is marketed for symptomatic relief associated with pharyngitis, laryngitis, tonsillitis, sore throat, and loss of voice. Its product-specific pharmacological target and mechanism in throat disorders are not established in the identified sources; the well-known central nervous system actions of valproic acid should not be assumed to describe this bismuth-valproate salt or its local throat indication.
