4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Bone Density Conservation Agents

Agents that inhibit BONE RESORPTION and/or favor BONE MINERALIZATION and BONE REGENERATION. They are used to heal BONE FRACTURES and to treat METABOLIC BONE DISEASES such as OSTEOPOROSIS. (See all compounds classified as Bone Density Conservation Agents.)


Calcium-Regulating Hormones and Agents

Hormones and molecules with calcium-regulating hormone-like actions that modulate OSTEOLYSIS and other extra-skeletal activities to maintain calcium homeostasis. (See all compounds classified as Calcium-Regulating Hormones and Agents.)


Vitamins

Organic substances that are required in small amounts for maintenance and growth, but which cannot be manufactured by the human body. (See all compounds classified as Vitamins.)
