Why this discipline needs its own guide
Background
Pharmacology and pharmaceutical sciences merge academic research with commercial regulatory requirements. Contributions must fulfill both publishing standards (NISO CRediT) and GxP standards (Good Laboratory Practice [GLP], Good Clinical Practice [GCP], and Good Manufacturing Practice [GMP]).
Attributing CRediT contributor roles in pharmacology ensures that compound synthesis, bioanalytical assay validation, pharmacokinetics/pharmacodynamics (PK/PD) modeling, preclinical toxicology, and the preparation of regulatory dossiers are credited with high accuracy.
Key considerations
How to assign the roles
- Distinguish chemical synthesis (Resources or Investigation) from chemical design, quantitative structure-activity relationship (QSAR) design, or retrosynthetic discovery strategies (Conceptualization or Methodology).
- Writing custom mathematical modeling scripts (e.g., in R, MATLAB, WinNonlin, or Phoenix) belongs to Software. Executing the simulations and calculating parameter estimations maps to Formal Analysis.
- Sourcing and maintaining validated cell cultures or animal strains maps to Resources. Performing dosing, physical observations, or organ extractions maps to Investigation.
- Managing, organizing, and formatting submission files for Investigational New Drug (IND) or Clinical Trial Applications (CTA) maps to Project Administration.
- Independent audit of raw bioanalytical datasets against standard operating procedures (SOPs) belongs under Validation.
Reporting Guideline Integration
Preclinical Pharmacology to CRediT Crosswalk
Mapping Preclinical Evaluation, Assays, and Pharmacokinetics to CRediT Roles
Preclinical pharmaceutical development demands strict compliance with GLP and rigorous reporting. This crosswalk aligns core preclinical evaluation elements with standard NISO CRediT contributor roles.
| Checklist Item / Phase | Mapped CRediT Role(s) | Guidance & Practical Allocation |
|---|---|---|
| 1. Compound Synthesis & CharacterizationDesigning, synthesizing, and validating the chemical purity of therapeutic molecules. | ResourcesValidation | Synthesizing or providing the test compound is Resources. Verifying structural purity and quality (e.g., NMR, HPLC, MS) maps to Validation. |
| 2. In Vitro Receptor AssaysExecuting ligand-binding, enzyme inhibition, and cell-based activity assays. | MethodologyInvestigation | Developing the bioassay protocol is Methodology. Performing the cell culture and instrument measurements is Investigation. |
| 3. Preclinical Animal DosingAdministering compound treatments, setting dose groups, and monitoring preclinical physiological safety. | InvestigationResources | Executing drug administration, blood sampling, and clinical observations is Investigation. Breeding and housing animal cohorts is Resources. |
| 4. Bioanalytical Method ValidationDeveloping and validating quantitative bioanalytical assays in biological matrices (plasma, tissue). | MethodologyValidationInvestigation | Optimizing and validating the assay (e.g., FDA bioanalytical guidelines) is Methodology. Independent audit of calibration curves is Validation. Running matrix extractions and LC-MS/MS analyses is Investigation. |
| 5. PK/PD Modeling & SimulationMathematical modeling of concentration-time profiles and pharmacodynamic responses. | Formal AnalysisSoftware | Fitting compartment or non-compartment models and calculating PK parameters is Formal Analysis. Writing custom analytical programs or simulation code is Software. |
| 6. Safety & Histology ToxicologyBlinded microscopic evaluation of tissue sections, biochemical marker testing, and toxicity grading. | InvestigationValidation | Slicing organ tissues and preparing histology slides is Investigation. Performing blinded pathological evaluation and score validation maps to Validation. |
| 7. Regulatory Dossier AssemblyDrafting, reviewing, and assembling Investigator Brochures (IB) and IND/NDA modules. | Project AdministrationWriting – Original DraftWriting – Review & Editing | Synthesizing scientific findings into regulatory modules is Writing – Original Draft. Managing document version control and scheduling submission timelines is Project Administration. |

Common questions
Frequently asked
Does PK/PD compartment modeling belong to Software or Formal Analysis?
It involves both: writing custom scripting pipelines or model frameworks belongs under Software, while running fitting algorithms, extracting parameter estimates, and calculating confidence intervals belongs under Formal Analysis.
How are clinical research monitors and quality assurance officers credited?
Quality assurance (QA) auditors who verify clinical data fidelity and confirm protocol compliance map to Validation and Project Administration.
Is preparation of Investigational New Drug (IND) regulatory submissions covered by CRediT?
Yes. Writing the regulatory sections is Writing – Original Draft, while overall management of the IND dossier submission, timeline, and document assembly is Project Administration.
