Metformin is one of the most commonly used medications in endocrinology. It is the preferred first-line oral blood glucose-lowering medicine to manage type 2 diabetes. It is also used in the treatment of polycystic ovary syndrome. Sometimes it is used, along with other medications, to treat infertility.
The journal Diabetologia dedicated a special issue this month to Metformin, which is celebrating 60 years of clinical use.
Most people don’t know that metformin has been in use for sixty years! The effectiveness of the plant from which metformin is derived has been known since 1918. The plant Gallegos officinalis (goat’s rue, also known as French lilac or Italian fitch) was noted to have sugar-reducing properties then. Initial experiments with metformin went well, but the discovery of human insulin for the treatment of diabetes put metformin on the back-burner. Metformin was rediscovered in the 1940s. The French physician Jean Sterne was the first to pursue the glucose-lowering effect of metformin. He reported the use of metformin to treat diabetes in 1957.
Over the years, the ability of metformin to improve the way the body processes and responds to insulin was appreciated more and more through Europe. After intensive research, metformin was introduced into the USA in 1995.
Long-term benefits on heart health were identified by the UK Prospective Diabetes Study (UKPDS) in 1998. This provided yet another reason for metformin to become first-line treatment for diabetes.
Sixty years after its introduction, metformin has become the most prescribed sugar-lowering medicine worldwide with the potential for other uses.

The Food and Drug Administration (FDA) has approved Tymlos (abaloparatide) injection for the treatment of postmenopausal women with osteoporosis at high risk for fracture. High risk for fracture is defined as history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, Tymlos reduces the risk of vertebral and nonvertebral fractures.
The FDA’s approval of Tymlos was based on results from the ACTIVE trial and an extension of this trial. These studies demonstrated significant reductions in the risk of vertebral and nonvertebral fractures regardless of age, years since menopause, presence or absence of prior fracture and bone mineral density (BMD) at baseline. In clinical studies, Tymlos reduced the incidence of new vertebral and nonvertebral fractures, and increased bone mineral density (BMD).
The results from the ACTIVE trial were published in the Journal of the American Medical Association in August of 2016, and the results of the first six months of ACTIVExtend were published in the Mayo Clinic Proceedings in February 2017.
Specifically, in the ACTIVE trial, TYMLOS demonstrated significant reductions in the relative risk of new vertebral and nonvertebral fractures compared to placebo in the ACTIVE trial of:
- 86% in new vertebral fractures
- 43% in nonvertebral fractures
The absolute risk reductions were 3.6% and 2.0%, respectively.
Abaloparatide caused a dose-dependent increase in the incidence of osteosarcoma (a malignant bone tumor) in male and female rats. The effect was observed at systemic exposures to abaloparatide ranging from 4 to 28 times the exposure in humans receiving the 80 mcg dose. It is unknown if Tymlos will cause osteosarcoma in humans.
For this reason, the use of Tymlos is not recommended in patients at increased risk of osteosarcoma including those with Paget’s disease of bone or unexplained elevations of alkaline phosphatase, open epiphyses, bone metastases or skeletal malignancies, hereditary disorders predisposing to osteosarcoma, or prior external beam or implant radiation therapy involving the skeleton.
Adverse Reactions: The most common adverse reactions (incidence ≥2%) are hypercalcemia, hypercalciuria, dizziness, nausea, headache, palpitations, fatigue, upper abdominal pain and vertigo.
Reminders About Osteoporosis
Osteoporosis is a silent disease, often displaying no signs or symptoms until a fracture occurs, leaving the majority of people with osteoporosis undiagnosed and untreated. Osteoporotic fractures create a significant healthcare burden. An estimated two million osteoporotic fractures occur annually in the United States, and this number is projected to grow to three million by 2025.
The National Osteoporosis Foundation (NOF) has estimated that eight million women already have osteoporosis, and another approximately 44 million may have low bone mass placing them at increased risk for osteoporosis
Screening is key to diagnose osteoporosis. Once osteoporosis is diagnosed, it is very important to undergo a thorough evaluation to look at secondary factors that can contribute to osteoporosis. Once the evaluation is complete, you and your physician can review the best treatment plan for you.

Texas Diabetes & Endocrinology was excited about one the world’s largest endocrinology conferences being in Austin this year. The Annual Scientific & Clinical Congress of the American Association of Clinical Endocrinologists was held in Downtown Austin between May 3rd and 7th. This is a world-renowned meeting which highlights the latest technological and medical advances in endocrinology. The program included expert speakers covering the latest developments and workshops presenting cutting-edge research to practitioners from around the world.
The most recent developments in diabetes treatment received extensive coverage at the conference. Dr. Thomas Blevins from Texas Diabetes & Endocrinology presented our clinic’s early experience with the new closed-loop insulin pump system in patients with type 1 diabetes.
In other sessions, attendees learned about recent developments in diabetes care. A special workshop reviewed data from recent studies evaluating the impact of diabetes medications on heart health.
One of the messages was that good sugar level control can have a significant impact on heart health. A study published in Diabetologia, showed that about 2.5% of patients with type 2 diabetes had known heart failure. Further detailed evaluation showed that up to 27.7% of patients had early signs or findings of heart failure. Importantly, by using medications that are known to reduce the risk of heart disease in patients with diabetes we can prevent the development and progression of these early stages of heart problems.
The special session also touched on different diabetes medications and their effects on heart function. The EMPA-REG outcome study which showed a significant reduction in heart disease and stroke-related deaths with the use of empagliflozin was reviewed. Another agent, liraglutide also reduced cardiovascular deaths, and the study that demonstrated this finding was the LEADER study.
The meeting was a major success overall, and it was a great opportunity for Texas Diabetes & Endocrinology providers to show off their city to colleagues from around the world!

The Endocrine Society recently issued a Clinical Practice Guideline recommending continuous glucose monitors (CGMs) as the gold standard of care for adults with Type 1 diabetes. Here at Texas Diabetes & Endocrinology, we provide comprehensive training and support for continuous glucose monitoring.
The guideline, titled “Diabetes Technology—Continuous Subcutaneous Insulin Infusion Therapy and Continuous Glucose Monitoring in Adults: An Endocrine Society Clinical Practice Guideline,” was published online and also appeared in the November 2016 print issue of The Journal of Clinical Endocrinology & Metabolism (JCEM), a publication of the Endocrine Society.
Continuous glucose monitors (CGMs) are primarily used to help in the management of Type 1 diabetes, although the devices can be useful for people with type 2 diabetes, as well.
Studies have found that people with Type 1 diabetes who use CGMs are able to maintain better control of their blood sugar without increasing episodes of hypoglycemia when blood sugar drops to dangerous levels, compared to those who self-monitor blood glucose with periodic fingersticks,” said Anne L. Peters, MD, of the University of Southern California’s Keck School of Medicine in Los Angeles, CA, and chair of the task force that authored the guideline. “Scientific evidence supports the use of CGM technology in individuals with Type 1 diabetes whose blood sugar is above the targeted level as well as those whose blood glucose is well managed.”
