Aims and Scope

Mission Statement
TJPLS is an international, double-blind peer-reviewed, open-access journal dedicated to accelerating pharmaceutical innovation for tropical and subtropical populations. The journal provides a rigorously vetted platform for research that translates bench discoveries into affordable, stable, and clinically relevant therapies for diseases of regional and global health importance.

Vision
To be recognized among indexed international journals as a leading source of evidence-based pharmaceutical research that addresses therapeutic gaps in tropical regions, while adhering to the highest standards of publication ethics and scientific transparency as defined by COPE, ICMJE, and ICH.

Aims
Advance Science: Publish original, methodologically robust studies that contribute new knowledge to pharmaceutical sciences.
Regional Relevance: Prioritize research on disease burden, drug stability, and formulation challenges specific to ICH climatic zones III and IV.
Bridge Gaps: Connect academic research with regulatory, industrial, and clinical practice in resource-constrained settings.
Capacity Building: Encourage submissions from early-career researchers and institutions in low- and middle-income countries through transparent, supportive peer review.
Ethical Publishing: Maintain zero tolerance for plagiarism, data fabrication, and unethical authorship, with all content screened by iThenticate and archived via Portico.

Scope
TJPLS considers manuscripts that report substantial experimental, theoretical, or clinical advances in the following thematic areas. All submissions must articulate clear pharmaceutical or therapeutic significance. Manuscripts lacking direct drug or health relevance will be returned without review.

Thematic Area 1: Pharmaceutical Technology & Advanced Drug Delivery Systems
Formulation design and evaluation of conventional and novel systems: solid dispersions, nanoparticles, liposomes, niosomes, microspheres, microemulsions, self-nanoemulsifying systems, transdermal films, ocular inserts, buccal patches, gastroretentive systems, and 3D-printed dosage forms. Studies on Quality by Design, Process Analytical Technology, scale-up, and stability testing under tropical conditions per ICH Q1A-Q1F are especially encouraged.

Thematic Area 2: Pharmacognosy, Phytochemistry & Herbal Technology
Ethnopharmacological surveys with quantitative data, isolation and structural elucidation of bioactive compounds from tropical flora, development and standardization of AYUSH and herbal formulations, monograph development, HPTLC/HPLC fingerprinting, herb-drug and herb-herb interaction studies, and in-vitro/in-vivo correlation of traditional claims.

Thematic Area 3: Pharmacology, Toxicology & Therapeutics
Mechanistic preclinical studies on tropical and lifestyle diseases including malaria, dengue, chikungunya, tuberculosis, leishmaniasis, diabetes mellitus, hypertension, and neurodegenerative disorders. Papers on neuropharmacology, cardiovascular pharmacology, immunopharmacology, safety pharmacology per ICH S7A/S7B, and OECD-compliant acute/sub-chronic toxicity are within scope.

Thematic Area 4: Pharmaceutical & Medicinal Chemistry
Design, synthesis, and biological evaluation of new chemical entities; computational chemistry including molecular docking, QSAR, pharmacophore modeling with experimental validation; development and validation of analytical methods per ICH Q2(R2); impurity profiling, metabolite identification, and stability-indicating assays.

Thematic Area 5: Biopharmaceutics, Pharmacokinetics & Pharmacometrics
BCS/BDDCS classification studies, dissolution method development, bioavailability and bioequivalence, IVIVC, population pharmacokinetics, PK-PD modeling, and application of modeling & simulation in dose optimization for tropical populations.

Thematic Area 6: Clinical Pharmacy, Social Pharmacy & Public Health
Pharmacovigilance studies, medication therapy management, drug utilization research, antimicrobial stewardship, pharmacoepidemiology, and health-outcomes research focused on tropical disease management and rational drug use in hospital and community settings.

Thematic Area 7: Pharmaceutical Biotechnology & Biopharmaceuticals
Plant cell and tissue culture for production of secondary metabolites, microbial fermentation, development and characterization of biosimilars and vaccines for neglected tropical diseases, and regulatory aspects of biologics.

Geographic Focus
TJPLS particularly welcomes research addressing pharmaceutical needs of South Asia, Southeast Asia, Sub-Saharan Africa, and Latin America. Studies must comply with international ethical standards irrespective of region.
