File contents

SIDER - Side Effect Resource

Category: Drug-centric | Type: DB | Subcategory: Adverse Drug Reaction (ADR)
Link: http://sideeffects.embl.de/ | Paper: https://doi.org/10.1093/nar/gkv1075

SIDER contains marketed medicines and their recorded adverse drug reactions, mined from public documents and package inserts.

Entity Type Auto-Detection

Input Pattern	Detected As	Example
`CIDxxxxxxxxx`	STITCH ID	`CID100000085`
`Cxxxxxxx` (8-char, digits after C)	UMLS CUI	`C0011849`
`X##XX##` (7-char ATC pattern)	ATC code	`N05BA01`
anything else	free text	`aspirin`, `headache`

Free text first attempts exact/substring match on drug names; if no drug is matched, it searches side-effect and indication names.

API

Function	Input	Returns
`search(entity)`	single entity string	`dict` with drug_name, stitch_ids, atc_codes, side_effects, indications, freq
`search_batch(entities)`	list of entity strings	`dict[str, dict]`
`summarize(result)`	one result dict	compact text string
`to_json(result)`	one result dict	same dict (pipeline passthrough)

Usage

from 14_SIDER import search, search_batch, summarize

# Single query — drug name
result = search("aspirin")
print(summarize(result))

# Single query — STITCH ID
result = search("CID100000085")
print(summarize(result))

# Single query — side-effect text
result = search("headache")
print(summarize(result))

# Batch query — mixed entity types
results = search_batch(["metformin", "ibuprofen", "C0011849"])
for entity, r in results.items():
    print(summarize(r))

Data Files

All pre-downloaded and extracted under:

File	Content
