Evidence & regulatory context
- Mechanism
- No ChEMBL mechanism_of_action record for clodronic acid. Clinically a non-nitrogenous bisphosphonate (ATC M05BA02); in the source study the liposomal formulation is used to deplete phagocytic macrophages. Co-agent rolipram resolved separately as CHEMBL63 (phosphodiesterase 4 inhibitor, target CHEMBL2093863, max_phase 2).

Model: Contusion spinal cord injury
Combined liposomal clodronate and rolipram produced the greatest neuroprotection, axonal sparing and locomotor recovery after contusion SCI.

Model: Closed articular fracture of the left tibial plateau by controlled compression (10 N pre-load then 20 N/s to fracture, indenter displacement limited to 2.7 mm); right hind limb served as uninjured contralateral control
Intra-articular macrophage depletion did not reduce synovitis or synovial macrophage numbers 7 days after fracture. Depletion of MaFIA mice 2 days before fracture significantly increased synovitis (P = 0.003) and reduced tibial metaphyseal bone mineral density (P = 0.002 in the results text, P = 0.…
