Abstract: Addiction is increasingly understood as a disorder of maladaptive synaptic learning, where drug exposure recruits silent synapses and strengthens pathological circuits that drive craving and relapse. Neuropeptides such as orexin, CRF, and dynorphin strongly modulate these circuits, yet their interaction with silent synapse biology remains underexplored. This article proposes Neuropeptidergic Silent Synapse Remodelling Therapy (NSSRT), a conceptual framework that integrates neuropeptide modulation with targeted synaptic plasticity to weaken or re‑silence drug‑linked connections. The model outlines a staged approach: stabilising dysregulated neuropeptide systems, safely activating addiction‑related circuits, and biasing plasticity toward AMPA receptor removal to restore NMDA‑only silent synapse proportions. Drawing on evidence from rodent cocaine studies, neuropeptide pharmacology, and BDNF‑dependent plasticity, NSSRT predicts a substantial reduction in cue‑ and stress‑induced relapse vulnerability. Although theoretical, this framework highlights a mechanistic pathway for circuit‑level intervention and suggests broader relevance for disorders characterised by maladaptive plasticity, including PTSD and Alzheimer’s disease.
