Patent coverage: 17,872 distinct patent families (69,326 SureChEMBL compound mentions), from 3 matched compound structure(s). One matched structure accounts for 68,757 (99%) of the total. Mentions count patents naming the compound (not distinct inventions), so promiscuous / reference molecules inflate the mention figure — families are the dedup metric.

Pharmacology

Pharmacogenomics

No CPIC/DPWG dosing guideline, but PharmGKB curates 2 clinical and 14 variant annotation(s) for this drug (gene-keyed; see PharmGKB).

Molecules sharing ≥1 of this drug’s curated primary targets, merged from two biobtree sources and ranked by shared-target count, then clinical phase: ChEMBL clinical-stage candidates (development phase ≥2) and PubChem drug-class bioactivity (approved / known drugs acting on the target). Deduplicated by drug name; the drug’s own salt forms are excluded. Note: for a drug with few primary targets a shared-target match can reflect off-target / promiscuous binding rather than the same therapeutic mechanism — the phase ordering surfaces bona-fide therapeutics first.
