Model Integration and Configuration for DTP Pharmacy

Data Characteristics for This Category

DTP pharmacies prepare registration and declaration documents using data primarily from pharmaceutical companies. This includes drug inserts, clinical trial reports, pharmaceutical research data, manufacturing process documents, and various approval and registration certificates. This data typically consists of unstructured or semi-structured documents in formats like PDF, Word, and Excel. Update frequency depends on drug development progress, regulatory revisions, and certificate renewals, making updates episodic and non-continuous. Document structures are rigorous, adhering to National Medical Products Administration (NMPA) template requirements, such as the declaration document items in the "Drug Registration Management Measures" appendix. Fields and units are highly specialized, including generic names, brand names, indications, dosages, adverse reactions, pharmacological and toxicological data, and units like milligrams (mg), milliliters (ml), and degrees Celsius (°C). Batch management information, such as drug batch numbers, production dates, and expiration dates, is also included.

Constraints Imposed by These Characteristics on Model Integration and Configuration

The specialized nature and structural requirements of DTP pharmacy data impose specific constraints on model integration. A high proportion of unstructured documents necessitates models with excellent text parsing and information extraction capabilities to accurately identify key fields. The non-continuous nature of data updates means models must support incremental updates and version management to ensure knowledge base timeliness. Documents adhering to NMPA templates require preprocessing or structured annotation of these templates during model training and knowledge base construction, improving model accuracy in recognizing specific sections and content. Specialized fields and units demand that models accurately understand their semantics, preventing data errors due to unit confusion. For example, recognizing dosage data requires distinguishing between adult and pediatric dosages and correctly associating units. This impacts the settings for chunk size and recall count to ensure contextual completeness and relevance.

Configuration Settings

Configuration Item	Recommended Value	Rationale for This Value
`Chunk size`	`800–1200 characters`	Registration and declaration document paragraphs are typically long. This range helps maintain contextual integrity and reduces semantic fragmentation.
`Recall count`	`Top 5–8 entries`	Ensures retrieval of enough relevant document snippets to cover multiple key information points in drug inserts.
`Similarity threshold`	`0.75–0.85`	Improves retrieval accuracy, prevents irrelevant or low-relevance document snippets from entering the context, and ensures data rigor.
`Rerank result count`	`Top 3 entries`	Performs a secondary sort based on initial recall, prioritizing the most relevant and core registration and declaration information.
`maxContext`	`4000 tokens`	Accommodates the complexity of DTP pharmacy data, providing sufficient context length for the large model to understand and generate.
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Provides ample file parsing time when processing large PDF or Word documents, preventing timeouts.

Three Common Mistakes

The model returns drug dosages or usage instructions that do not match the original text. This is due to imprecise recognition of specialized terminology and units, or a Similarity threshold set too low, introducing noisy information.
After uploading large declaration document files, the system displays a "file parsing timeout" error. This likely occurs because the PARSE_FILE_TIMEOUT_SECONDS parameter is too small to handle complex or large-volume documents.
During AI conversations, the model stops generating or cannot continuously answer follow-up questions. This happens when maxContext or max_tokens parameters are set too low, leading to context overflow.

How to Confirm Correct Configuration

Upload a typical drug insert PDF. Verify if the model correctly parses the document structure and accurately extracts key fields like generic names and indications.
For a specific drug batch number, ask for its production date and expiration date. Cross-reference the model's returned information with the original approval data and check for correct units.
Simulate a declaration document review scenario. Ask multiple consecutive questions about drug pharmacology, toxicology, and adverse reactions. Observe if the model maintains contextual coherence and provides reasonable responses. Compare these responses with human review results.
