Types – Within the broader application framework, therapeutic agents are classified into nucleos(t)ide analogues, interferon‑based products, and emerging entry‑inhibitors. Nucleos(t)ide analogues (e.g., tenofovir, entecavir) dominate the market, delivering >80% of prescriptions due to their oral administration, high potency, and low resistance rates. Interferon‑based therapies (standard and pegylated) represent roughly 15% of usage; they are reserved for patients seeking finite treatment courses or those contraindicated for nucleos(t)ide therapy, despite higher adverse‑event profiles. Entry‑inhibitors and other novel mechanisms, still in late‑stage development, occupy the remaining ~5% and are projected to expand as resistance patterns evolve. The distribution of these types reflects clinical decision‑making: nucleos(t)ide analogues address the bulk of chronic cases, interferons target specific subpopulations, and emerging agents aim to capture unmet needs, thereby shaping the overall market taxonomy for Hepatitis B Treatment segmentation.
