This case report presents a 52-year-old Caucasian female patient with osteopenia who experienced an unexpected 15.9% increase in lumbar spine BMD within two years after enrolling in a clinical trial involving low-dose rapamycin and subsequently starting low-dose naltrexone. This case potentially opens novel treatment strategies for bone density improvement in aging populations.
Osteoporosis is caused by the failure to differentiate osteoblasts. I am not sure whether Osteopenia is essentially the same or not. That links to the energy levels of the cells which is an aging thing. As Rapamyin fixes that issue it is probably Rapamycin rather than naltrexone. I am not aware of what effects naltrexone would have in this situation.
