The Purple Pill for Reflux? Choose the Cheapest


Proton Pump inhibitors (PPI) are one of the most widely prescribed medications in the world. Why are there 5 different PPIs on the market to treat acid reflux? Is one better than the other? Is the cheaper generic (Omeprazole) as good as Prevacid? or Protonics? or Aciphex? or Nexium?

With the help of The American Family Physician Journal, let me dispel the confusion. First, there are different brands of the same drug because it is a multi million dollar market and a tiny percent of that market is real $$$. It's called market share.

In reviewing the 41 studies comparing the various PPIs that were used to treat peptic ulcers or gastroesophageal reflux disease (GERD), the authors found no differences among any of the drugs.

Let's look at the monthly price differential between these products:
Nexium 20mg --- $158
40mg --- $137
Prevacid 15mg --- $153
30mg --- $147
Protonics 20mg --- $128
40mg --- $125
Prilosec 10mg --- $115
20mg --- $136

Omeprazole (Generic Prilosec) 10mg ---$27
20mg ---$21

In summary: All PPIs are effective in equipotent doses. Go for the least expensive!

What about Zantac ? does it gives the same relief for "Gerd". This "reflux problem" seems to be getting to be a problem for more and more people. Stress maybe , and of course a diet that has too many "Hot" spices and in some cases I believe "Food Allergies"

Zantac is a little different. It is an "acid blocker" and also works for reflux and Gerd. It is over the counter and another brand is Pepsid. They can be taken PRN (as needed) for heartburn & reflux. Alcohol, smoking and large meals late at night are triggers.

You are exactly right.

Many people worry that generic drugs lack in quality because they are substantially cheaper than there brand name counterparts. Generics are required by the FDA to have the same quality, strength, purity and stability as brand-name drugs.

According to the FDA, "Generic drugs are less expensive because generic manufacturers don't have the investment costs of the developer of a new drug. New drugs are developed under patent protection. The patent protects the investment—including research, development, marketing, and promotion—by giving the company the sole right to sell the drug while it is in effect. As patents near expiration, manufacturers can apply to the FDA to sell generic versions. Because those manufacturers don't have the same development costs, they can sell their product at substantial discounts. Also, once generic drugs are approved, there is greater competition, which keeps the price down. Today, almost half of all prescriptions are filled with generic drugs."

The drug war between the anti-impotency medicines such as Viagra, Cialis and Levitra is continuously on the rise but instead of preferring the other two erectile dysfunction drugs Cialis and Levitra, impotency afflicted men are opting for viagra only, the Pfizer manufactured drug to treat erectile dysfunction. This is because Viagra if the first erectile dysfunction medication to provide men successful relief from impotency and to known more about tidbits on Viagra, please visit the website http://www.viagraforce.com

Often when one goes to seek medical attention from a health care provider, that provider usually writes a prescription for that patient for medication to either treat the symptoms of the disease that may be present.

Or, the health care provider may actually cure the disease, as with the case regarding antibiotics.

Also, the provider may prescribe medications to delay the progression of a disease that may exist with their patient.

The actual cost of that medication the patient receives from a pharmacy can vary greatly, and here is why:

More now than in the past, generic medications have been encouraged and selected by prescribers at a much higher rate.

Health care providers are aware that generic drugs are less expensive than branded drugs that are equivalent to the generic drug prescribed as far as safety and efficacy are concerned.

Nearly two thirds of all medications prescribed to patients in the United States are now for generic medications.

Generic medications are bioequivelant copies of branded medications that previously existed, yet no longer have a patent on these medications, which allows generic drug companies to produce these formally expensive drugs and a much lower cost.

Why aren’t generic medications prescribed all the time, then?

The branded drugs have their company sales representatives who leave samples of these branded medications with the health care provider, with the intention and belief that this provider will select this branded drug as a result.

Generic medications, while much less expensive than branded medications, do not have samples of these drugs to be left with health care providers.

Around 4 billion prescriptions filled every year, so cost savings is rather important.

Generic medications are about two thirds of this total pharmaceutical market with the drugs included in this market.

However, while most prescriptions are for generic medications, this still is less than 15 percent of the total money spent on prescription drugs.

With branded medications, about 75 percent of these newly approved drugs by the FDA are similar in efficacy as drugs that already exist in this market, so there is no benefit with many of these expensive branded drugs.

Roughly half of all newly approved prescription drugs have had serious side effects soon after they have been approved, so newer is clearly not always better, of course, as it relates to safety for the patient taking the drug.

Most recently, certain managed health and prescription providers have been actually paying doctors to initiate if not switch their patients from branded medications they may be taking to generic medications, if possible.

This may be due to a reaction caused by branded pharmaceutical companies offering similar inducements to health care providers to select their promoted medications.

Both financial inducements that occur are remarkably legal, overall. Yet I find financial inducements in health care inappropriate and unethical when a health care provider treats a patient with prescribing medications for them.

Not long ago, generic drugs were not prescribed that often, or produced to a great degree, because of the cost of bringing such a med to the market, which at the time required the same clinical trial protocols as branded meds.

Fast forward to 1984, as this is when the Hatch-Waxman Act was introduced.

This Act only required generic meds to demonstrate bioequivalence to the branded med that they desire to reverse engineer.

So nothing else was now required in the approval process that is mandated by branded medications to be completely developed and approved by the FDA.

This reduced cost of generic manufacturing and approval allowed for more of these meds to saturate the pharmaceutical market, and doctors started prescribing more generic meds as a result.

Branded pharmaceutical companies were not pleased in large part with this new act.

So some drug companies devised schemes to extent the patents of their branded meds through such tactics as altering their existing branded medication by combining it with another generic drug from another class of medications.

This tactic is referred to as evergreening, and the tactic extends the patent life of their branded drug of concern.

Additional branded drug company tactics include frivolous patent infringement lawsuits, which delays generic availability for a longer period because of these lawsuits.

Also, branded pharmaceutical companies have been known to actually pay generic manufacturers to not release the equivalent of a branded medication they wish to continue to promote.

The pharmacies that fill the prescriptions for the patients written by the health care providers support generic use, as pharmacies make more money off of generic prescriptions they fill for others compared with branded drugs.

Generics seem to remain a concern to branded companies in spite of their efforts of avoiding their access into a market they believe to own.

Recently, branded pharmaceutical companies have either purchased smaller generic drug companies, or have started to produce generic medications on their own.

This is due to the progressive impact generic drugs are having on the business of branded drug companies.

Also, other reasons for increased generic prescribing may be due to the awareness and clinical experience of the previous branded med that has now been replicated by the generic medication.

Again, newer drugs at times are not a desirable choice of treatment for patients because of understandable concerns by the prescriber.

One particular concern is safety that has not fully established with a new medication.

The familiarity of the generic drug accessible to them after the patent expiration of a branded medication the prescriber has utilized often in the past with treatment success for their patients allows the prescriber to utilize the generic equivalent not that it is available often.

Many clinical studies have proven that generics are as effective compared with branded medications for particular disease states.

The cardiovascular disease trial called the ALLHAT trial showed this. In this trial, with surprise to many, the old class of drugs called diuretics showed equivalence if not superiority over the branded medication utilized in this trial.

This comparative effectiveness trial lasted over four years, and was funded mostly by the NIH.

Most encouraging for even greater use of generic meds is that at least one company has created vending devices for doctor’s offices for dispensing both generic and over the counter drugs.

This may discourage the use of branded equivalent drugs at a greater amount with generic samples available with this method.

In addition, and in some cases, doctors can order generic samples from the manufacturers directly.

Both mechanisms for obtaining samples of generic drugs by a health care provider remain quite rare, however.

Then there are some health care providers who insist that you get what you pay for, so they are convinced that branded drugs are always more efficacious and tolerable than generic medications.

This misconception is largely a fallacy, as both are determined to be bioequivalent, since the generic drug has to show this in order for the drug to be authorized for use by prescribers.

Efficacy differences may exist, but are thought to be minimal.

I’m sure it’s possible others have encouraged such doctors to take such a stance that is absent of evidence.

In the U.S. Health Care System, cost is a rather large concern for members of the public health, and those who attempt to restore their health as it needs to be at times.

Generic medications provide financial relief for patients in need of drugs to improve their health.

And both the health care provider as well as the patient can be assured that a generic drug prescribed to, and taken by, a patient will provide the efficacy needed to address the medical problems of the patient.

More importantly, the patient saves money, without compromising their safety,

I read with interest the comment by Quiact in which he took pains to explain that generic drugs are required to be the equivalent of the original, "Innovator" versions. But I looked in vain for any mention of the fact that the FDA allows generic drugs to vary in their potency plus or minus 20% from the original (hardly the same formulation if that is the case).

Referring to the Hatch-Waxman Act of 1984, Quiact states that "This Act only required generic meds to demonstrate bioequivalence to the branded med that they desire to reverse engineer."

A closer look at the act shows the standards for determing "bioequivalence" are very broad.

In fact, according to the "Overview of the Hatch-Waxman Act and Its Impact on the Drug Development Process", by Gerald J. Mossinghoff,

"The FDA still uses the plus-or-minus-twenty-percent test to determine blood serum bioavailability (i.e., the amount of active ingredient in the blood over a period of time has to come within plus-or-minus twenty percent of that which is observed when the innovator’s drug is ingested). Twenty percent is a fairly good margin, and many medical professionals believe that for drugs that have a wide index of tolerance, twenty percent is not important at all; in such instances, twice as much or half as much of the active ingredient in a generic product will still work. For drugs where there is a very narrow therapeutic band, for example, where a patient gets antiseizure medication, plus-or-minus twenty percent may not be appropriate."

And given that the "non-active" ingredients can also vary by a 40% total range, their effects can also vary widely and unexpectedly.

I know of a number of instances where a pharmacy substituted a generic "equivalent"--or even switched generics--without notifying the customer or the doctor. As a result blood tests to determine any changes in the drug's effects could not be ordered, and often undesirable results were experienced without any warning, due simply to the change in the dosage in an "equivalent" generic.

The complete overview document is available at various websites (some of them charging for it), including a free link at

http://www.fdli.org/pubs/Journal%20Online/54_2/art2.pdf

Looks like generics are not necessarily the same after all!

I've been hearing a lot about this medication, and I think we need more information and ads about, and O.K. it is the most important because the pump actively transports protons from the matrix of the mitochondrion into the space between the inner and outer mitochondrial membranes but we can't understand the main processes behind all this explanations. 2j3j
