Anabolic Medications Make New Bone

Anabolic medication for osteoporosis actually increases bone thickness and strength!  Antiresorptive medications for osteoporosis (Fosamax, Alendronate, Actonel, Atelvia, Boniva, Evista, Reclast, Prolia) only preserve bone.

We have talked about all of the Antiresorptive medications over the last 2 months.  They are excellent treatment if slowing down the OsteoClasts (cells that eat away your bone) is sufficient.  That is not always the case.

Now it is time to talk about something completely different.  Anabolic medication stimulates the OsteoBlasts (cells that make new bone matrix).  OsteoBlasts can rebuild your bones.  If you have Fractures, your bones may need to be rebuilt.

Forteo (Teriparatide) is the only Anabolic medication for osteoporosis in the USA.  Close cousins of Forteo are available in other countries.

You may need the Anabolic, Forteo, if you have a hip fracture, multiple other fractures, or if VFA testing reveals a Vertebral Compression Fracture.  A DXA T-score well below -2.5 can be reason enough without fracture.

Glucocorticoid (Cortico-Steroid) medications (Prednisone, Steroid Inhalers) specifically supress OsteoBlasts (cells that make new bone).  Stimulating the OsteoBlasts with the Anabolic, Forteo, can offset the bone loss from Steroid medications.  Smoking also supresses OsteoBlasts, leading to bone loss.  Stopping Smoking would be best, but Forteo can help.

Not everyone needs an Anabolic, but some individuals do.  A Complete Bone Health Evaluation will tell you if an Anabolic is right for you.

More about Forteo (Teriparatide) next time.

Denosumab – Prolia – OPG Analog

Denosumab (Prolia) mimics the natural process that keeps OsteoClasts (the cells that gobble up bone) under control before menopause.  OsteoCytes release Osteoprotegrin (OPG) when Estrogen (or Testosterone) is on board.  OPG controls the formation and activation of OsteoClasts by blocking RANK-Ligand, which is necessary for OsteoClast formation and activation.  This decreases fracture risk.

Prolia mimics OPG and blocks RANK-Ligand, thus blocking bone resorption by preventing OsteoClasts.  It is a RANK-Ligand Antibody.  It is like birth control for OsteoClasts.  Prolia is given as a shot under the skin twice a year.  Prolia is very effective at first, but begins to fade by 6 months.  Without another injection , Prolia has totally lost effectiveness by 12 months after the last shot.

Acute Phase Reaction

An Acute Phase Reaction can occur the first time a person is exposed to a new class of medication.  With each subsequent dose, half as many people have the reaction.  The symptoms are like mild flu for 3 to 5 days.  The treatment is lots of fluids, and Tylenol (Acetaminophen) if needed.

Persons who have never taken any bisphosphonate before, can experience an acute phase reaction the first time they take Reclast (Zolendronate in osteoporosis dose).  This happens in about one-third of persons who have not taken Fosamax (Alendronate), Boniva (Ibandronate), Actonel (Risedronate), or Atelvia (enteric coated Risedronate) before their first dose of Reclast.  This happens in about one-sixth of persons after their second dose.  Third dose is down to one-twelfth.

Acute phase reaction is a significant nuisance.  However, a Fracture is a significant problem.  Reclast will reduce Fracture Risk by more than half compared to no osteoporosis medication at all.  See the visuals for fracture risk in women and men without osteoporosis medication.  Remember to check for good enough kidney funtion (GFR at least 45) before each dose.

It’s all about avoiding Fractures.

No GERD with Reclast

Bisphosphonates are often associated with Gastro Esophageal Reflux Disease (GERD).  When GERD cannot be adequately controlled by medication, we cannot use oral bisphosphonates.  Yet there is an advantage to taking a medication which will accumulate in bone and last well beyond the last dose.  That is where Reclast shines.

Reclast (Zolendronate in osteoporosis dose) is given IV.  Intravenous (IV) means no Gastro-Intestinal issues at all.  Therefore persons with Irritable Bowel Syndrome (IBS), or Crohn’s, or Colitis can take Reclast.  The once a year dosing is convenient.  But giving a whole year of medication all at one time requires extra care.
