Drug Classes (1)

ClassDescription
1,1-bis(phosphonic acid)Any member of the class of phosphonic acids in which a carbon atom is directly attached to two phosphonic acid groups. They are analogues of pyrophosphates (with the central oxygen atom replaced by a carbon atom) and like pyrophosphates they tend to have a strong affinity for bone, so are frequently used for their antiresorptive and hypocalcaemic properties.

Parkinson Disease
A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.
