China demands evidence that traditional medicine injections really work

Better late, then never! 😊

"China is about to apply its growing scientific expertise to one of its most cherished cultural treasures: traditional medicine. Last fall, government agencies with authority over pharmaceuticals and health issued draft guidelines calling on companies that make traditional Chinese medicine (TCM) injections—many of them used for decades—to provide evidence that they are safe and effective and explain how they work. If the companies don’t comply, their products will be removed from the market. ...

will only apply to TCM products that are injected intramuscularly or intravenously, not to the remedies widely taken by mouth in China and overseas. TCM injections have been plagued by inconsistent evidence of benefits and a spotty safety record. ..."

Circadian rhythms of the liver can influence drugs’ effectiveness

Amazing stuff! Take your pills on time or your liver will not forgive it! 😊

The influence of the circadian rhythms on all kinds of bodily function has been known for decades. Here is more about it!

"Using tiny, engineered livers derived from human patients, ... researchers found that more than 300 liver genes are under circadian control. These circadian variations affect how much of a drug is available and how effectively the body can break it down. ...
The study also revealed that the liver is more susceptible to infections such as malaria at certain points in the circadian cycle, when fewer inflammatory proteins are being produced. ...
It is estimated that about 50 percent of human genes follow a circadian cycle ...
Most of these genes clustered in two groups — about 70 percent of the genes peaked together, while the remaining 30 percent were at their lowest point when the others peaked. These included genes involved in a variety of functions, including drug metabolism, glucose and lipid metabolism, and several immune processes. ..."

From the abstract:
"Critical aspects of physiology and cell function exhibit self-sustained ~24-hour variations termed circadian rhythms. In the liver, circadian rhythms play fundamental roles in maintaining organ homeostasis. Here, we established and characterized an in vitro liver experimental system in which primary human hepatocytes display self-sustained oscillations. By generating gene expression profiles of these hepatocytes over time, we demonstrated that their transcriptional state is dynamic across 24 hours and identified a set of cycling genes with functions related to inflammation, drug metabolism, and energy homeostasis. We designed and tested a treatment protocol to minimize atorvastatin- and acetaminophen-induced hepatotoxicity. Last, we documented circadian-dependent induction of pro-inflammatory cytokines when triggered by LPS, IFN-β, or Plasmodium infection in human hepatocytes. Collectively, our findings emphasize that the phase of the circadian cycle has a robust impact on the efficacy and toxicity of drugs, and we provide a test bed to study the timing and magnitude of inflammatory responses over the course of infection in human liver."

FDA Drug Approval Process Is Deeply Flawed

Posted: 7/10/2018

Vicious Cycle Of Government Intervention Since 1906

If you need an example of an almost ideal/stylized, but unfortunately, all too real vicious cycle of excessive government intervention just take the official history of drug approval by the U.S. Food And Drug Administration.


The only positive entry I could find perusing this history was: “1905 The American Medical Association (AMA) begins a voluntary program of drug approval that would last until 1955. In order to advertise in the AMA and related journals, drug companies must show proof that the drug will treat what they claim”. Without the vicious cycle of government interventions, we would probably have a much better system of private, voluntary drug testing and approval.

Thalidomide 1962

First, I am not a doctor nor am I medically trained etc.

The Thalidomide scandal of 1962 and its aftermath is a great example of a highly irrational, overreaction by our elected representatives that was never corrected. Thalidomide apparently has been an important drug. It is still used today.

In the U.S., the Thalidomide disaster was prevented thanks to “FDA inspector Frances Kelsey, who prevented the drug’s approval within the United States despite pressure from the pharmaceutical company and FDA supervisors. Kelsey felt the application for thalidomide contained incomplete and insufficient data on its safety and effectiveness. Among her concerns was the lack of data indicating whether the drug could cross the placenta, which provides nourishment to a developing fetus.” (emphasis added)

So what actually caused the breakdown of safety tests and approval for this drug? The sources below do not really tell.

It was approved as an over the counter drug in 1957 in Germany on the safety claims of the maker (what?). Did any German health authorities then approve this drug? Why was this drug so quickly promoted and sold as a morning sickness treatment for pregnant women (on the claims of the maker that it was safe for pregnant women as well)?

“Between 1958 and 1960 it was introduced in 46 different countries worldwide”. How was that possible that this drug was so fast approved and marketed worldwide?

“Around this time [1960?], Australian obstetrician Dr. William McBride discovered that the drug also alleviated morning sickness. He started recommending this off-label use of the drug to his pregnant patients, setting a worldwide trend. ” Did nobody verify this claim?

Apparently, highly advanced countries like the UK had inadequate government drug approval procedures in place up to 1962. How come?

“Until Thalidomide tragedy, the drugs were being sold by notification to health authority and NO safety, efficacy or quality data were required to be submitted prior marketing.” This was the sorry, troubling state of affairs in Western Europe.


Since The Thalidomide Scandal Drug Efficacy Needs Approval

Before Thalidomide (1962), the FDA drug approval process was only concerned with drug safety. Then, U.S. legislators rushed to pass the so called the Kefauver Harris Amendment (a.k.a. Drug Efficacy Amendment), which required drug efficacy as well. We still suffer from this incredibly misguided and short-sighted decision! This was certainly not the “finest achievement in consumer protection”, rather the opposite or everything else!

How Many Lives Were Shorted!

We will perhaps never find out how many lives were shortened since the the drug efficacy requirement came into effect in the U.S. However, I bet many more people were prematurely killed or harmed then by Thalidomide, because new and safe drugs were not speedily approved based on safety alone.
