Secondary Osteoporosis is the demineralisation and subsequent weakening of the bones causes by medical conditions, procedures and medications. These are characterised by causing bone loss, increasing fracture risk, directly affecting bone remodelling, indirectly affecting bone remodelling or interfering with the attainment of peak bone mass in younger individuals.

Medications

The table below is adapted from the International Osteoporosis Foundation and summarises things nicely:

Drug Class Loss of Bone Mineral Density (BMD) Examples
Androgen deprivation therapy (ADT) BMD declines by 2-5% during the first year of ADT. oserelin, triptorelin, buserelin and leuprolide
Aromatase inhibitors (AI) Approx increase in loss of BMD of 0.5-1% per year anastrozole, exemestane and letrozole
Glucocorticoids (GC) All patients at increased risk of bone loss betamethasone, prednisolone, cortisone
Selective serotonin reuptake inhibitors (SSRI) Still under review but increased fracture risk citalopram, sertraline, fluoxetine
Thiazolidinediones (TZD) Reduce bone formation and increase reabsorption Pioglitazone (can also be combined with metformin)

Chemotherapy drugs, lithium and methotrexate are also linked with increased risk of osteoporosis and should also be considered.
