This narrative review synthesizes how next-generation antimycobacterial strategies can be translated “from molecule to patient” by coupling potent therapeutics with delivery platforms tailored to the lesion microenvironment. We survey emerging small-molecule classes, including decaprenylphosphoryl-β-D-ribose 2′-epimerase (DprE1) inhibitors, mycobacterial membrane protein large 3 (MmpL3) inhibitors, and respiratory chain blockers, alongside optimized uses of established agents and host-directed therapies (HDTs). These are mapped to inhalable and nanocarrier systems that improve intralesional exposure, macrophage uptake, and targeted release while reducing systemic toxicity. Particular emphasis is placed on pulmonary dry powder inhalers (DPIs) and aerosols for direct lung targeting, stimuli-responsive carriers that trigger release through pH, redox, or enzymatic cues, and long-acting depots or implants that shift daily dosing to monthly or quarterly schedules to enhance adherence, safety, and access. We also outline translational enablers, including model-informed pharmacokinetic/pharmacodynamic (PK/PD) integration, device formulation co-design, manufacturability, regulatory quality frameworks, and patient-centered implementation. Overall, aligning stronger drugs with smart delivery platforms offers a practical pathway to shorter, safer, and more easily completed TB therapy, improving both individual outcomes and public health impact.</jats:p>","journal":"Pharmaceutics","year":2026,"id":634450,"datarank":0.16479184330021646,"base_score":1.0986122886681096,"endowment":1.0986122886681096,"self_citation_contribution":0.16479184330021646,"citation_network_contribution":0.0,"self_endowment_contribution":0.16479184330021646,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":2,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1645497,"name":"Eman Marzouk","orcid":"0000-0003-1699-6263","position":1,"is_corresponding":false},{"id":1645499,"name":"Adil Abalkhail","orcid":"0000-0002-2294-9837","position":2,"is_corresponding":false},{"id":1645496,"name":"Ayman Elbehiry","orcid":"0000-0001-7726-9532","position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"resolved":true,"title":"Advancing Tuberculosis Treatment with Next-Generation Drugs and Smart Delivery Systems","abstract":"<jats:p>Tuberculosis (TB) remains a leading infectious killer, increasingly complicated by multidrug-resistant (MDR) and extensively drug-resistant (XDR) disease; current regimens, although effective, are prolonged, toxic, and often fail to reach intracellular bacilli in heterogeneous lung lesions.
