The Tardive Dyskinesia Treatment segmentation by type is anchored in two pharmacological classes: VMAT2 inhibitors and off-label alternatives. VMAT2 inhibitorsโvalbenazine and deutetrabenazineโaccount for the dominant revenue share because their selective dopamine modulation delivers proven, label-approved efficacy and favorable reimbursement. Off-label options (amantadine, clonazepam, tetrabenazine, botulinum toxin) collectively form a smaller yet strategically important slice; they are leveraged when cost, access, or comorbidity profiles restrict branded VMAT2 use, and their generic pricing keeps unit volumes comparatively high despite lower per-patient revenue.
