Interactions

Risedronate Sodium: Co-admin with calcium, antacids or oral medications containing divalent cations may affect the absorption of risedronate. May have additive calcium lowering effects when used with aminoglycosides. Calcium: Co-administration with thiazide diuretics or vit D may lead to milk-alkali syndrome and hypercalcaemia. Decreased absorption with corticosteroids. Decreases absorption of tetracyclines, atenolol, iron, quinolones, alendronate, Na fluoride, Zn and calcium-channel blockers.

Mode of Action

Risedronic acid inhibits bone resorption by inhibiting osteoclasts. It also prevents formation and dissolution of hydroxyapatite crystals, and therefore may interfere with bone mineralisation. Calcium is used to prevent or treat negative calcium balance. It also helps facilitate nerve and muscle performance as well as normal cardiac function. Bone mineral component; cofoactor in enzymatic reactions, essential for neurotransmission, muscle contraction, and many signal transduction pathways.
