Novartis Blood Pressure Medication Runs into Trouble by Gary Pepper, M.D. Editor, Metabolism.com In 2007 a new type of blood pressure lowering medication was brought to market by Novartis Pharmaceutical Company. This medication by the brand name Tekturna (aliskiran) works by blocking hormones that make up a circuit from the kidney to the blood vessels know as the RAAS system. This mechanism is distinct from all other blood pressure lowering medications available. By working via a completely novel pathway to lower blood pressure doctors were given another potent weapon in the war on high blood pressure. A second medication, Valturna, which combines an established blood pressure medication with Tekturna, was released by Novartis to the public in 2009. These drugs have been extremely popular due to their effectiveness and apparent freedom from serious side effects. A warning about this class of drug was issued by Novartis, 2 weeks ago when it was forced to end the Altitude drug study due to apparent unforeseen complications in patients using Tekturna and Valturna. The study found a small but significant increase in stroke in diabetics with renal disease who were using these drugs. Although the group of patients in the Altitude study are up to 12 times more likely to develop stroke or heart attack under normal circumstances, Novartis had no choice but to end the study and issue a warning to the health care community about limiting the use of these drugs.
In my own practice I have found Tekturna and Valturna to be extremely effective and well tolerated. A survey of my colleagues revealed the same findings. Diabetes and high blood pressure very commonly occur together and national guidelines stress the need for excellent blood pressure control for diabetics to help prevent heart, kidney and eye complications of this disease. For doctors treating diabetics who recognize these patients as particularly high risk, having to significantly cut back or eliminate the use of Tekturna and Valturna is creating major concerns. Within the past week I have had to counsel numerous individuals about these issues and the solution is far from easy. For instance, one man with diabetes and early kidney disease and heart disease, with borderline high blood pressure despite using 4 different types of blood pressure medication including Tekturna has to decide with me, which is the greatest risk, going off the medication resulting in a rise in his blood pressure or continuing a drug which may pose a risk of its own.
These discussions are going on in doctor’s offices throughout the country with no good solution in sight. The only certainty is a flood of ads by lawyers which begin, “Have you ever been on Tekturna or Valturna….”.
The mission of the The Thyroid Project is to encourage sharing of information and experience between the public and the medical community about the treatment of hypothyroidism (low thyroid function). For at least the past few decades there is a growing awareness of â€œsomething missingâ€ in the way suffers of hypothyroidism are treated for their disease.
Too many patients, as documented in an on-line study of 12,000 individuals conducted by the American Thyroid Association published in June 2018, (https://doi.org/10.1089/thy.2017.0681) , complain of persistent symptoms of hypothyroidism despite what their doctors believe is successful treatment with levothyroxine (brands include Synthroid, Unithroid, Tirosent, Levoxl). We believe something needs to be done to resolve this conflict between patients and their doctors.

Metformin has been the mainstay of diabetes treatment for 50 years with an impressive array of success stories in terms of effectiveness and affordability. On top of this, recent research points to the unexpected potential of metformin for the ability to reduce the risk of dementia and cancer and may even slow the aging process. So why is this drug so under-rated? Our review at metabolism.com digs into these intriguing questions.
