Bristol-Myers Squibb Company announced  that TEQUIN, a quinolone antibiotic, reached the  one million new  prescription mark in the United States in its first ten months on the market.  Approved by the U.S. Food and Drug Administration on  December 17,1999,  TEQUIN is the only  quinolone antibiotic to achieve this milestone during the first ten  months on the market, according to audited  data (October, 2000) from IMS Ltd. Previously, the ten-month new prescription record for quinolones was held by Levaquin(R) (levofloxacin,  Ortho-McNeil).

WASHINGTON, April 18 (UPI) -- Johnson and Johnson's first quarter earnings soundly beat Wall Street's expectations, but analysts expressed concern about the company going forward due to the safety issues revolving around anemia and stent products…Global Levaquin sales rose 18 percent to $475 million, including a 50- percent increase outside of the United States to $15 million.


Avelox was first approved in 1999 in both Europe and the United States. As of March 2003 there have been nearly 17 million prescriptions in more than 80 countries worldwide.

There have been more than 300 million prescriptions worldwide for Ciprofloxacin. Which exceeds the total population of the United States in 2005


Ciprofloxacin and Levofloxacin together command 65% ($3.3 billion) of global sales.

It has been estimated that more than 10% of the ENTIRE world population has been prescribed a fluoroquinolone and at a bare minimum more than 13 million such patients had experienced an adverse reaction that was not recognized, reported or treated by the physician. However it is strongly suspected that the number of untreated patients to be much greater than this. These numbers continue to increase on a daily basis due to the ignorance and arrogance of the treating physician, as well as rampant scripting abuses.


Despite many published case reports and approximately 3500 cases of tendinopathy that has been reported to the World Health Organization Collaborating Centre for Drug Monitoring, little is known about the mechanisms behind this fluoroquinolone-specific toxicity. Even though such events have been reported for over thirty years the treating physician still to this day, maintains that tendon rupture is not a known adverse drug reaction to the fluoroquinolones.


Between 1995 and 2002, fluoroquinolones became the most commonly prescribed class of antibiotics to adults in the United States. Forty-two percent of fluoroquinolone prescriptions were for non approved diagnoses. Among patients receiving antibiotics, non-approved fluoroquinolone was very common with such prescribing increasing over time. Fluoroquinolone prescribing increased threefold in outpatient clinics and emergency departments in the United States from 1995 to 2002.


Fluoroquinolones became the most commonly prescribed class of antibiotics to adults in 2002.


"… The Nancy (France) pharmacovigilance centre studied the frequency of adverse drug reaction reports per 100,000 patients of rheumatological adverse effects of fluoroquinolone antibiotics such as joint pain and tendon damage using three different methods. Method one was traditional spontaneous reporting. This is the same system used in the U.S. If an adverse reaction is suspected by a health professional the reaction is hopefully reported to the FDA Method two was "encouraged" reporting in which prescribers were asked by Nancy pharmacovigilance centre if they had observed rheumatological side effects with fluoroquinolones. Method three was termed "reinforced" reporting. Prescribers of fluoroquinolones were identified using prescription records and were asked the same questions about fluoroquinolones by social security authorities.  The reporting of adverse rheumatological effects  from fluoroquinolones  varied enormously between the three  methods. The traditional  spontaneous reporting  system produced 1 report per 100,000 patients; "encouraged" reporting  18 per 100,000; and the "reinforced" method 342 reports of adverse rheumatological effects -- including joint pain and tendon damage--per  100,000 patients. Thus,  the rate of reports of these adverse reactions to fluoroquinolones was 342 times higher in the group of doctors identified as having prescribed the  drugs and specifically asked if they had  observed these adverse reactions."

 "..However, postmarketing surveillance has revealed significant hepatotoxicity  with trovafloxacin…. In  perspective, rare but  serious hepatotoxicity has been reported with other  fluoroquinolones and the  overall incidence of trovafloxacin hepatotoxicity is not dissimilar to that reported with flucloxacillin  and amoxicillin-clavulanic acid… rare but serious hepatotoxicity has been reported with other fluoroquinolones…. Prolongation of the QTc interval is also a class effect,… Tendinitis and rupture, usually of the Achilles tendon, are rare, class-effects of fluoroquinolones,… (Note that this was stated over SIX YEARS AGO by two of the quinolones "head cheerleaders")

 "…the development of  severe neuropsychiatric problems including hallucinations and  psychosis were reported. The reactions occurred predominantly in the  elderly... (Ball, 1989; Jungst &  Mohr, 1988). "

A systematical and comprehensive evaluation of all reports on adverse drug reactions ascribed to ofloxacin since this antibiotic was launched (1985) until October 1988 shows that severe adverse drug reactions are more often reported spontaneously than in the course of clinical trials. In particular, severe reductions of white blood cell counts, shock and shock fragments, and impairment of sensory organs and renal functions have for the first time been detected by spontaneous case reports. The results demonstrate exemplarily the potency of the spontaneous reporting system as superior to that of clinical trials in providing information on rare adverse drug reactions.

"Widespread antibiotic use in animals is suspected to have led to the development of resistance in humans and many regulatory authorities, including Australia, are moving to severely restrict or ban their use. From January 1, 2006 Europe will ban the routine prophylactic use of antibiotics in animal feed. The US has already banned fluoroquinolones and while they are moving more slowly than Europe, fast food organizations and other customers in the US are already causing producers to adapt and find alternatives."

Of note, fluoroquinolone  use in the 18- to 44-year age group more than doubled from 2000 to 2002 (14% to 30%). Among fluoroquinolones prescribed over all years of the study, 74% were for levofloxacin; 51% of levofloxacin prescriptions were considered inappropriate-These findings suggest that those prescribing antimicrobial drugs may be increasingly using fluoroquinolones as a "one-size-fits-all"  regimen without accounting for differences due to age and other risk factors


 Zithromax and Levaquin were the top-selling antibiotics in the United States in 2004 with about

 $1.7 billion in sales. No  other antibiotic exceeded  $800 million.

The scripting abuse continues unimpeded and the number of clueless victims continues to grow accordingly.
