Codeine HCL: Incomplete Evidence Pack — Drug Repurposing Evaluation Not Possible

One-Sentence Summary

Codeine HCL is a well-known opioid analgesic and antitussive agent used for pain management and cough suppression. The TxGNN model returned no predicted indications for this candidate, most likely because the DrugBank ID could not be resolved, preventing the drug from being matched to the knowledge graph. The current Evidence Pack contains multiple critical data gaps that block a complete repurposing evaluation.

Quick Overview

Item	Content
Original Indication	Not available
Predicted New Indication	None returned by TxGNN
TxGNN Prediction Score	N/A
Evidence Level	N/A
South Africa Market Status	Not marketed
Number of SAHPRA Registrations	0
Recommended Decision	Hold

Safety Considerations

Please refer to the SAHPRA-approved Professional Information (PI) for safety information. Report adverse drug reactions to SAHPRA.

Conclusion and Next Steps

Decision: Hold

Rationale: The TxGNN knowledge graph pipeline could not generate any repurposing predictions for Codeine HCL because the DrugBank ID was not resolved, meaning the drug could not be linked to the knowledge graph. Without predictions, a repurposing evaluation cannot proceed. Additionally, the drug has no current SAHPRA registrations on record, and all safety data fields carry unresolved data gaps.

To proceed, the following is needed:

Resolve DrugBank ID — Search DrugBank for “codeine” (likely DB00318) and confirm the correct entry for Codeine HCL; update the candidate record with the verified drugbank_id.
Re-run TxGNN prediction pipeline — Once the DrugBank ID is confirmed, re-run the KG and DL prediction steps to generate repurposing candidates with scored indications.
Retrieve MOA data — Query the DrugBank API for mechanism of action (opioid receptor agonism) to populate the original_moa field and enable mechanistic reasoning.
Obtain SAHPRA PI / safety data — Confirm whether Codeine HCL is registered in South Africa under a combination product (e.g., with paracetamol or ibuprofen); download the approved Professional Information (PI) to extract warnings and contraindications.
Verify market status — Codeine-containing products are commonly registered as combination medicines in many markets; a targeted SAHPRA database search under combination product names is recommended before concluding the drug is entirely absent from the South African market.
