  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In young ovariectomized rats, rhPTH-(1-84) reduced femoral trabecular bone loss when treatment started 2 weeks after ovariectomy.

    Summary
    Thus daily subcutaneous injections of 0.6 nmol/100 g of body weight of rhPTH-(1-84) or hPTH-(1-31)NH2 into 3-month-old OVX rats for 6 weeks starting 2 weeks after OVX equally reduced the otherwise large OVX-triggered loss of femoral trabecular bone.

    Summary
    4 or 0.8 nmol/100 g of body weight of the two agents for 6 weeks also equally increased the mean thickness of the remaining femoral trabeculae in 3-month-old and 1-year-old OVX rats to 20 to 80% above the value in normal animals when started 9 weeks after ovariectomy.
