Did you know that Boring, Oregon and Dull, Scotland – yes these
are real localities- have bonded to promote tourism?
There is a slight difference in size but neither is a metropolis.
Boring’s population is about 8000; Dull north of Glasgow has 20 houses and 80
residents. Dull has no sidewalks to take in at night.
I hope that my little rants about the state of health care are
neither “dull” or “boring” but informative.
One of the health care scams being promulgated on the public
is the half truth that generics and brand name drugs are equal; implied is that
there is no difference except cost.
Those who are seeking all routes in lowering the costs
especially the insurance companies and government in their benefit programs are
the protagonists for generic use. The drug
chains like them because even though there is a great difference in retail
price their profit margins for the generic are much better.
It would be un-American the to legislated limits on percent markups
over costs on medicines and procedures excluding the professional component. Yet everyone approves of mandated fee
schedules by Insurers as well as Medicare and Medicaid which are often below
the breakeven point in a practice. Obviously that means that an equitable
income cannot be reached.
To get back to the generics; the blanket statement that all
generics and brand name drugs are equal is false.
All medicines with the same chemical formulation have the
same active ingredient. Milligram to milligram they are the same. But, the standard
of variation in therapeutic potency which may depend on actual amount of active
ingredient in the tablet or capsule of medicine differs for brand name drugs
and their generics.
Even if the chemical formula for a drug is the same there
can be a variation in therapeutically response. This can be applicable to identical
brand name drugs as well as generics.
This can have no relationship to any manufacturing variations in the
amount of “drug” in the pill.
One of the most famous examples year ago had to do with two
brand name levothyroxin products; Synthroid and Levoxol. Too many physicians’
surprise it turned out that the two brands were not interchangeable; a switch
from one to the other resulted in a therapeutic difference in the patient. The
possibility of this happening with generics is greater.
The brand name drugs are held to a narrow variation range in
amount of the active ingredient in the tablets. The generic manufactures are
permitted greater variation above or below the stated amount. There also is difference
in the fillers that must be taken into account.
This is from MedicineNets description of the drug:
GENERIC NAME: levothyroxine sodium
BRAND NAME: Synthroid,
Levoxyl, Levothroid, Unithroid, Tirosint, Levo-T
DRUG CLASS AND MECHANISM: Levothyroxine is a
synthetic (man-made) version of the principle thyroid hormone, thyroxine (T4)
that is made and released by the thyroid gland. Thyroid hormone increases the
metabolic rate of cells of all tissues in the body. In the fetus and newborn,
thyroid hormone is important for the growth and development of all tissues
including bones and the brain. In adults, thyroid hormone helps to maintain
brain function, utilization of food, and body temperature, among other effects.
GENERIC AVAILABLE: Yes. Generic and branded tablets
of levothyroxine may differ: in the
amount of levothyroxine they contain, in the absorption of the levothyroxine into the body, and the distribution of levothyroxine
throughout the body.
This means that ingestion of 1 mg of generic levothyroxine
may not have the same effect on the body as 1 mg of another generic or branded
levothyroxine. Practically speaking, this means that when changing between
levothyroxine manufactured by different pharmaceutical companies, a change in
dose may be necessary to maintain the desired effect or to prevent toxicity. When switching between brands or generics,
it is important to ensure that both preparations are equivalent or to check
blood thyroid levels weekly.
One of the compounding problems with generics is that the
pharmacy May change manufacturers due to a better price without notification to
the consumer.
This problem is applicable to all medicines. Recently the
FDA approved generic alternatives for an effective anti-glaucoma eye drops. Ophthalmologists
have reported variations in eye pressure which had been stable for years. It is
possible that damage could happen to an unsuspecting patient who knew his medicine was
controlling his disease.
The point that I am making is that there always is a chance
that a switch to a generic will mean that the impact on your body may change.
This does not mean that you should not use generics but be advised that not all
will respond exactly like your brand drug. If you are on a generic and doing
well stick with it but check the manufactures name to be sure that there has
not been a change in you medicine.
