Frequently Prescribed Diabetic Medication from Thomas Smith, “Insulin: Our
Silent Killer
The following
diabetic medication or diabetic drugs are widely prescribed for Type 2 diabetes. For those who prefer
to understand what the doctor is really doing we include this section.
The
information contained in this section is the reason the writer of this article
refused
orthodox treatment. The oral hypoglycemic agents in wide use, fall into the
following five diabetic classes of diabetic drugs.
These diabetic classifications are defined according to their bio-physical mode of
action. These diabetic classes are: Biguanides, Glucosidase inhibitor, Meglitinides,
Sulfonylureas & Thiazolidinediones.
In addition to these synthetic diabetic drugs, the
physician has available to him a number of different forms of insulin. We will
look at all of these agents in this section.
As mentioned earlier, none of the diabetic
medications offered by the “drug company-physician axis” cures either Type 2
diabetes or Hyperinsulinemia.
So, recognize that, as we proceed through this
section, all that we are really discussing is how to alleviate the
characteristic high blood sugar symptom. Note that some of these diabetic
drugs increase
the insulin level in patients that likely already have too much insulin in their
blood stream.
Diabetic
Medications
1.
Biguanides
Currently this oral glycemic category has one diabetic drug listed; it is:
Glucophage. This is a popular drug manufactured by Bristol Meyers Squibb
Company. Its active agent is “Metaformin”. It is packaged in small white
tablets containing 500mg and 850mg dosages. It acts, in ways that were not
clear in the PDR1, to lower blood glucose levels by three mechanisms. They are:
- it decreases hepatic glucose secretion
- it decreases intestinal absorption
of glucose and
- it increases peripheral uptake of glucose.
Its main positive
claims seem to be that it does not stimulate insulin production from the
pancreas, it does not seem to be metabolized by the liver and it does not
cause hypoglycemia.
However the PDR states that there were no studies made on
people with hepatic (liver) disfunction. Excretion is by the kidneys; it is
contraindicated for people with kidney disease.
This drug is prescribed for Type
2 diabetes.
Diabetic Medication side effects include: a small percentage risk of possible lactic
acidosis, caused by metaformin accumulation in the system; this is fatal to 50%
of those who experience it, however. The UGDP study3, which was referenced in
the PDR, found increased cardiovascular mortality with this product. It often
removes vitamin B12 from the system. Other side effects include, Ketoacidosis,
Hyperventilation, Myalgia, Malaise, unusual Somnolence, Diarrhea, Nausea,
Vomiting, Bloating, Flatulence and Anorexia.
This category of drug contained only one diabetic drug, Precose. It is
manufactured by the Rx. Pharmaceutical Division of Bayer Corporation. Its
active ingredient is Acarbose. It comes in 50mg and 100mg tablets.
In its
mode of action, it causes a competitive, reversible inhibition of the
digestive enzyme Alpha Amylase. This means that it interferes with the operation
of an important pancreatic enzyme that digests carbohydrates.
By this
mechanism it slows the digestion of carbohydrates and thereby reduces post
prandial blood sugar. It is recommended as adjunctive therapy with a
Sulfonylurea for Type 2 diabetes.
Diabetic Medication side effects of this drug include, elevated
Serum Transanimase and Hyperbilinemia. Both of these are characteristic of liver
involvement in the metabolism of the drug.
It lowers serum calcium and vitamin
B6. It is not recommended for those with kidney impairment. Its safety in
pregnancy has not been evaluated; the drug appears in breast milk when the drug
is taken by the mother and may affect the nursing infant.
Other diabetic drug side effects
include, Abdominal pain, Diarrhea and Flatulence.

“Endocrine function’’ 3 A study of oral hypoglycemic agents by the
“University Group Diabetes Program”
Again this category includes only
one drug, Prandin. Prandin is manufactured by Pfizer. It comes in yellow
tablets of 1mg and red tablets of 2mg. Its active ingredient is
Repaglinide.
Its mode of action is to stimulate the pancreas to produce
insulin. It is metabolized by the liver. The principal pathways are direct
oxidative transformation and by conjugation via the glucuronic pathway.
Metabolism requires a fully functional cytochrome P450 system. (For a
good
introductory discussion of how these pathways work see: “Encyclopedia of natural
medicine”, Michael Murray, N.D and Joseph Pizzorno, N.D. Rev 2nd Ed. 1998,
pp!04-125)
Some of the prominent liver metabolites are:
This drug is not recommended for
those with kidney or liver impairment. This drug appears in breast milk when the
drug is taken by nursing mothers.
Diabetic Medication side effects include, severe Hypoglycemia,
increased risk for Cardio-Vascular Mortality, Upper Respiratory Infection,
Sinusitis, Nausea, Diarrhea and Headaches.
4.
Sulfonylureas This class had six drugs listed. They are:
| Amaryl |
Diabeta |
Diabinese |
| Glucotrol |
Glynase |
Micronase |
Since the drugs
within a class share a similar mode of action and generally differ in only minor
ways, we selected one of the most popular for a closer look.
The one we selected
is Diabinase.
This drug is manufactured by Pfizer in l00mg and 250mg tablets.
Its active ingredient is Chlorpropamide. Its mode of action is to stimulate the
pancreas to secrete insulin.
This PDR (Physicians Desk Reference. 53 edition.
1999) sheet was noteworthy in that it contained some statements, which if
correctly understood, would encourage people to refuse this drug. I quote:
”This
diabetic drug is indicated for use as a secondary adjunct to diet for effective glycemic
control” and also ”Controlling the blood sugar alone has not been established to
be effective at preventing the long term cardio-vascular or neural complications
of diabetes.”
Before proceeding, we will stop and translate those two statements
in the PDR sheet for this sulfonylurea drug.
The first
statement tells us that this diabetic drug will not cure our diabetes and if we ever want
to achieve glycemic control we must control our appetite for the food that
causes Type 2 diabetes.
The second statement comes closer than anything I have
seen outside of research circles, to tell us that excess insulin is the
precursor to Atherosclerosis and Cardio-Vascular events.
This diabetic drug, of course,
elevates insulin levels in a patient that most probably already has excess
ineffective insulin. Very seldom does the physician check the insulin levels
before prescribing this drug.
For example, my physician prescribed this drug
without doing a GITT on me. This diabetic drug is contra-indicated if Ketoacidosis is
evident; insulin is recommended instead.
Loss of blood sugar control, even with
this diabetic drug, will occur under conditions of stress.
There is a
serious warning regarding increased risk of Cardio-Vascular events. This means
“Heart Attacks”.
Nursing mothers will pass this drug to their babies; the babies
will, as a result, suffer reversible Hypoglycemia. This drug is famous for
causing Hypoglycemia.
The diabetic medication side effects and adverse reactions that have been
experienced with this drug read like a list of the possible diseases that we
can acquire. They include, Hypoglycemia, Cholestatic, Jaundice, Nausea,
Diarrhea, Vomiting, Anorexia, Hunger, Pruritis, Uticaria,
Maculopopular Eruptions, Porphyria, Cutanatarda, Hepatic Porphyria,
Photosensitivity, Anemia, Exfoliative, Dermatitis, Leukopenia, Eosinophila,
and Water Retention.
The actual list is longer than this. I
list here just
enough to illustrate the idea.
This class lists only one drug, but it is a beauty. It is called
Rezulin. This drug is manufactured by Parke-Davis. Its active ingredient is
Troglitazone.
It does not act to increase pancreatic secretion of insulin. It
does not act to interfere with the digestive process.
Its mode of action is to
decrease hepatic glucose secretion and to increase glucose disposal in the
skeletal muscle.
It reputedly reduces Hyperglycemia, Hyperinsulinemia and
Hypertriglycerdemia. It is used for Type II diabetes.
This diabetic drug is metabolized
in the liver by the sulfate and glucuronidation pathways. It requires a healthy
cytochrome P450 liver detoxification system.
This diabetic medication is said to be compatible
with the Sulfony urea class of oral hypoglycemics discussed above and for
adjunctive use with insulin for Type 2 diabetes patients.
It is contra-indicated
for pregnant or breast feeding women, for patients with impaired liver function
and for patients with heart problems. Among the adverse reactions listed are:
Hypoglycemia, Reversible Jaundice, Hepatic Disfunction, Hepatitis, Nausea,
Vomiting, Abdominal Pain, Fatigue, Anorexia, Dark Urine, and Abnormal Liver
Function.
This diabetic drug may
render oral contraceptives ineffective. This drug may stimulate ovulation
in premenopausal women.
Some time ago, The Denver Post reprinted an article
from the Los Angeles Times about this particular drug Rezulin. The Rezulin
manufacturer mentioned in the article was Warner-Lambert although our more
recent PDR information lists Parke-Davis as the manufacturer.
The headline was:
Fast-track Diabetes drug tied to at least 33 deaths.
The article went on to
explain that this drug has been removed from the British market by their
counterpart to our PDA.
This diabetic
medication was rejected by a veteran PDA medical officer
assigned to review it because it was seriously damaging to the liver.
According
to this article, this officer, Dr. John L. Gueriguian, was subsequently removed
from the review process by his administrative superiors. After the first few
deaths attributed to this drug, another PDA medical officer, Dr. Robert I.
Misbin, estimated that more than 12,000 Rezulin users would experience liver
damage.
He advised his superiors that 2,000 of these patients were likely
to die from liver failure unless they were carefully monitored by their
doctors. This drug went on to achieve fast track approval by the FDA and is
currently being prescribed to American diabetes patients.
As this report
was being finalized for the printer we came upon two recent news items regarding
this drug Rezulin.
According to Dr. John J Brooks, the FDA has just recalled
this drug from the American marketplace because of its link with liver cancer
(JJ Brooks. M.D.. “Alternative Medicine research”. Vol. No 9. 3-26-00).
A
Minnesota law firm (Law offices of Charles H Johnson & Associates, Toll
free: 1 (800) 535-5727 as of April 26. 2000) is apparently preparing a major
law suit against the Rezulin manufacturers.
They, the law firm, ran an ad in the
Denver Rocky Mountain newspaper on April 25, 2000 in which they asked former
Rezulin users to call them to discuss possible damage compensation. One cannot
help but wonder about the connection, if any, between the law suit and the
recall of the drug.
Although injectable insulin is usually
thought to be useful primarily for the Type 1 diabetic, it is selectively
used for Type 2 diabetes as well.
Insulin was first isolated by Banting, Best
and Macleod, a Nobel prize winning team of Canadian researchers (JAC Brown,
M.B.. B. Chir.: “Pears medical encyclopedia, illustrated” , 1971, p250).
They
saved the life of a 14 year old girl who was dying in Toronto general hospital
of “diabetes.” This was in 1922.
The injectable insulin therapy, which had been
the object of intensive search since 1889 worked for the first time.
The therapy
worked because, unbeknown to the physician, the “diabetes” being treated was
what we now know as Type I diabetes.
At that time Type 2
diabetes was just
beginning to surface as a major epidemic and it was not recognised as the
entirely different disease that we now know it to be.
During this period
diabetes exploded from the relatively rare Type I to include a huge population
of not clearly recognized Type II diabetics.
This was when the
medical profession began to realize the connection between the disease and the
diet in the control of this epidemic. This, because insulin was proving not to
be the universal pancea touted by the drug company.
Later, when the distinction
was made between the two types of diabetes, this problem disappeared. Today
insulin is made from pork pancreas or beef pancreas; and, it is made with
recombinant gene technology.
Insulin is a protein; it consists of a unique chain
of amino acids. The pork and beef derived insulins differ from human insulin by
one or more amino acids.
The injection of what the body sees as a foreign
protein, sometimes causes an allergic response.
Insulin made with genetic
techniques from bacteria is claimed to be identical to human insulin and
minimizes the potential for allergic reaction.
There are a wide
variety of insulins available. They are classified by their mode of manufacture
and they are classified by their speed of action.
Some contain preservatives;
some indicate that they do not contain preservatives.
They fall into
three groups according to how long after injection the hypoglycemic effect
occurs (R Berkow M.D.; Editor in Chief, “Merck Manual of Medical Information”,
1997, p721):
Rapid
acting - Starts in 20 minutes, maximizes at about 2 to 4 hours, lasts 6
to 8 hours.
Intermediate acting - Starts in Ho3 hours, maximizes in
6 to 10 hours. Lasts 18 to 26 hours.
Long
acting - Starts in 6 hours, lasts 28 to 36 hours.
Manufacturers mix
and match insulin of the above three basic types to obtain a finer control on
the time and dose response of the patient.
When insulin was
isolated in 1922 it quickly gained a reputation for saving lives
because without insulin the diabetic, at some point, went into diabetic shock
and died.
The fact that the patient had to continue to take the insulin was
considered to be a major disadvantage of the treatment. It was used only because
it saved lives.
Many wanted a treatment that would cure the disease without the
need for continuing treatment. However, it is obvious that no economic
incentive exists within the medical community, as it is presently structured, to
find a real cure or to eliminate continuous treatment.
This
“disadvantage” was widely discussed in the medical community. By 1955, when oral
hypoglycemics first started to appear, the diabetic community was no longer
troubled by the continuing dependence on a drug for glycemic control.
Thus with
the disappearance of pressure to find a better medication, none was sought.
Today everyone is
acclimated to the idea of continuous treatment with no cure is sight. Indeed
this “c” word is no longer even in the medical vocabulary.
Today all
orthodox diabetic medications are of the type that must be
continually administered.
