Aminomux - General Information
Pamidronic acid (INN) or pamidronate disodium (USAN), marketed as pamidronate disodium pentahydrate under the brand name Aredia, is a bisphosphonate. [Wikipedia]
Pharmacology of Aminomux
Aminomux is in a class of drugs called bisphosphonates. Aminomux reduces breakdown of the bones. Aminomux is used in the treatment of Paget's disease of bone; to reduce high levels of calcium in the blood associated with malignancy (cancer); and to reduce the breakdown of bone due to metastases of breast cancer or multiple myeloma.
Aminomux for patients
Concomitant administration of a loop diuretic had no effect on the calcium-lowering action of Aredia.
Caution is indicated when Aredia is used with other potentially nephrotoxic drugs.
Also see CLINICAL PHARMACOLOGY
Aredia is contraindicated in patients with clinically significant hypersensitivity to Aredia or other bisphosphonates.

Mechanism Of Action: The mechanism of action of pamidronate is inhibition of bone resorption. Aminomux adsorbs to calcium phosphate (hydroxyapatite) crystals in bone and may directly block dissolution of this mineral component of bone. In vitro studies also suggest that inhibition of osteoclast activity contributes to inhibition of bone resorption. Aminomux also targets farnesyl pyrophosphate (FPP) synthase. Nitrogen-containing bisphosphonates (such as pamidronate, alendronate, risedronate, ibandronate and zoledronate) appear to act as analogues of isoprenoid diphosphate lipids, thereby inhibiting FPP synthase, an enzyme in the mevalonate pathway. Inhibition of this enzyme in osteoclasts prevents the biosynthesis of isoprenoid lipids (FPP and GGPP) that are essential for the post-translational farnesylation and geranylgeranylation of small GTPase signalling proteins. This activity inhibits osteoclast activity and reduces bone resorption and turnover. In postmenopausal women, it reduces the elevated rate of bone turnover, leading to, on average, a net gain in bone mass.
