3004.49.00.20 - Anticonvulsants, hypnotics, and sedatives

This HTS category, 3004.49.00.20, encompasses medicaments primarily affecting the central nervous system that are specifically classified as anticonvulsants, hypnotics, and sedatives. These products are formulated for therapeutic or prophylactic uses, presented in measured doses or retail packaging. This subcategory focuses on substances used to prevent or control seizures (anticonvulsants), induce sleep (hypnotics), or calm or reduce anxiety and excitement (sedatives).

It is crucial to distinguish this category from its siblings. While 3004.49.00.30 covers antidepressants, tranquilizers, and other psychotherapeutic agents, this category specifically excludes those broader classifications. Similarly, 3004.49.00.40 acts as a residual category for other medicaments affecting the central nervous system that do not fit into the more specific anticonvulsant, hypnotic, or sedative classifications. The defining characteristic here is the direct action on neuronal excitability for seizure control or the induction of a state of calmness or sleep.

As this is a leaf node within the HTS, there are no further subcategories. Classification within 3004.49.00.20 is determined by the pharmacological action and intended use of the medicament, specifically its role in managing epilepsy, insomnia, or states of agitation, and its presentation in a form ready for administration to patients.
