Approved drug Immunopharmacology Ligand
clodronic acid is an approved drug (UK (1999))
Compound class: Synthetic organic
Comment: Clodronic acid is a first generation (non-nitrogenous) bisphosphonate drug. Clinically used drugs can contain sodium clodronate tetrahydrate, sodium clodronate, disodium clodronate tetrahydrate or disodium clodronate.

Kato et al. (2017) report that clodronic acid-mediated inhibition of the vesicular nucleotide transporter (VNUT, SLC17A9) suggests that this drug has potential as a transporter-targeted (and notably, non-opioid) analgesic drug for the treatment of chronic neuropathic and inflammatory pain [1]. In this study clodronic acid was selective for VNUT compared to other vesicular transporters tested.
