4.2 Drug Indication

Optruma is indicated for the treatment and prevention of osteoporosis in post-menopausal women. A significant reduction in the incidence of vertebral, but not hip fractures has been demonstrated. When determining the choice of Optruma or other therapies, including oestrogens, for an individual postmenopausal woman, consideration should be given to menopausal symptoms, effects on uterine and breast tissues, and cardiovascular risks and benefits (see section 5. 1).


Evista is indicated for the treatment and prevention of osteoporosis in post-menopausal women. A significant reduction in the incidence of vertebral, but not hip fractures has been demonstrated. When determining the choice of Evista or other therapies, including oestrogens, for an individual postmenopausal woman, consideration should be given to menopausal symptoms, effects on uterine and breast tissues, and cardiovascular risks and benefits.


Raloxifene is indicated for the treatment and prevention of osteoporosis in postmenopausal women. A significant reduction in the incidence of vertebral, but not hip fractures has been demonstrated.

When determining the choice of raloxifene or other therapies, including oestrogens, for an individual postmenopausal woman, consideration should be given to menopausal symptoms, effects on uterine and breast tissues, and cardiovascular risks and benefits.


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Selective Estrogen Receptor Modulators

A structurally diverse group of compounds distinguished from ESTROGENS by their ability to bind and activate ESTROGEN RECEPTORS but act as either an agonist or antagonist depending on the tissue type and hormonal milieu. They are classified as either first generation because they demonstrate estrogen agonist properties in the ENDOMETRIUM or second generation based on their patterns of tissue specificity. (Horm Res 1997;48:155-63) (See all compounds classified as Selective Estrogen Receptor Modulators.)


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.)


Estrogen Antagonists

Compounds which inhibit or antagonize the action or biosynthesis of estrogenic compounds. (See all compounds classified as Estrogen Antagonists.)
