First Signs Bronchitis: Fluoroquinolone Antibiotics

The fluoroquinolones are a relatively new group of antibiotics. Fluoroquinolones were first introduced in 1986, but they are really modified quinolones, a class of antibiotics, whose accidental discovery occurred in the early 1960.

Because of their expanded antimicrobial spectrum, third-generation fluoroquinolones are useful in the treatment of community-acquired pneumonia, acute sinusitis and acute exacerbations of chronic bronchitis, which are their primary FDA-labeled indications. The third-generation fluoroquinolones include levofloxacin, gatifloxacin, moxifloxacin and sparfloxacin. The length of an article is rather immaterial about its response from people. People are more interested in the matter about Chronic Bronchitis, and not length. Rolling Eyes

Fluoroquinolones Advantages:

Ease of administration Daily or twice daily dosing Excellent oral absorption Excellent tissue penetration Prolonged half-lives Significant entry into phagocytic cells Efficacy Overall safety This article has been written with the intention of showing some illumination to the meaning of Chronic Bronchitis. This is so that those who don't know much about Chronic Bronchitis can learn more about it.

Fluoroquinolones disadvantages: Tendonitis or tendon rupture Multiple drug interactions Not used in children Newer quinolones produce additional toxicities to the heart that were not found with the older agents Evil or Very Mad

Side Effects

The fluoroquinolones as a class are generally well tolerated. Most adverse effects are mild in severity, self-limited, and rarely result in treatment discontinuation. However, they can have serious adverse effects. The more interesting an article, the more takers there are for the article. So we have made it a point to make this article on Bronchitis as interesting as possible! Very Happy.

Gastrointestinal Effects

The most common adverse events experienced with fluoroquinolone administration are gastrointestinal (nausea, vomiting, diarrhea, constipation, and abdominal pain), which occur in 1 to 5% of patients. CNS effects. Headache, dizziness, and drowsiness have been reported with all fluoroquinolones. Insomnia was reported in 3-7% of patients with ofloxacin. Severe CNS effects, including seizures, have been reported in patients receiving trovafloxacin. Seizures may develop within 3 to 4 days of therapy but resolve with drug discontinuation. Although seizures are infrequent, fluoroquinolones should be avoided in patients with a history of convulsion, cerebral trauma, or anoxia. No seizures have been reported with levofloxacin, moxifloxacin, gatifloxacin, and gemifloxacin. With the older non-fluorinated quinolones neurotoxic symptoms such as dizziness occurred in about 50% of the patients. Phototoxicity. Exposure to ultraviolet A rays from direct or indirect sunlight should be avoided during treatment and several days (5 days with sparfloxacin) after the use of the drug. The degree of phototoxic potential of fluoroquinolones is as follows: lomefloxacin > sparfloxacin > ciprofloxacin > norfloxacin = ofloxacin = levofloxacin = gatifloxacin = moxifloxacin. Musculoskeletal effects. Concern about the development of musculoskeletal effects, evident in animal studies, has led to the contraindication of fluoroquinolones for routine use in children and in women who are pregnant or lactating. Tendon damage (tendinitis and tendon rupture). Although fluoroquinolone-related tendinitis generally resolves within one week of discontinuation of therapy, spontaneous ruptures have been reported as long as nine months after cessation of fluoroquinolone use. Potential risk factors for tendinopathy include age >50 years, male gender, and concomitant use of corticosteroids. Hepatoxicity. Trovafloxacin use has been associated with rare liver damage, which prompted the withdrawal of the oral preparations from the U.S. market. However, the IV preparation is still available for treatment of infections so serious that the benefits outweigh the risks. Cardiovascular effects. The newer quinolones have been found to produce additional toxicities to the heart that were not found with the older compounds. Evidence suggests that sparfloxacin and grepafloxacin may have the most cardiotoxic potential. Hypoglycemia/Hyperglycemia. Recently, rare cases of hypoglycemia have been reported with gatifloxacin and ciprofloxacin in patients also receiving oral diabetic medications, primarily sulfonylureas. Although hypoglycemia has been reported with other fluoroquinolones (levofloxacin and moxifloxacin), the effects have been mild. Hypersensitivity. Hypersensitivity reactions occur only occasionally during quinolone therapy and are generally mild to moderate in severity, and usually resolve after treatment is stopped.

Second-generation agents include ciprofloxacin, enoxacin, lomefloxacin, norfloxacin and ofloxacin. Ciprofloxacin is the most potent fluoroquinolone against P. aeruginosa. Ciprofloxacin and ofloxacin are the most widely used second-generation quinolones because of their availability in oral and intravenous formulations and their broad set of FDA-labeled indications.

Third Generation

The third-generation fluoroquinolones are separated into a third class because of their expanded activity against gram-positive organisms, particularly penicillin-sensitive and penicillin-resistant S. pneumoniae, and atypical pathogens such as Mycoplasma pneumoniae and Chlamydia pneumoniae. Although the third-generation agents retain broad gram-negative coverage, they are less active than ciprofloxacin against Pseudomonas species.

The newer fluoroquinolones have a wider clinical use and a broader spectrum of antibacterial activity including gram-positive and gram-negative aerobic and anaerobic organisms. Some of the newer fluoroquinolones have an important role in the treatment of community-acquired pneumonia and intra-abdominal infections. As we got to writing on Bronchitis, we found that the time we were given to write was inadequate to write all that there is to write about Bronchitis! So vast are its resources.

First Generation

The first-generation agents include cinoxacin and nalidixic acid, which are the oldest and least often used quinolones. These drugs had poor systemic distribution and limited activity and were used primarily for gram-negative urinary tract infections. Cinoxacin and nalidixic acid require more frequent dosing than the newer quinolones, and they are more susceptible to the development of bacterial resistance. People are inclined to think that some matter found here that is pertaining to Chronic Bronchitis is false. However, rest is assured, all that is written here is true!

Conditions Treated With Fluoroquinolones: Indications and Uses

The newer fluoroquinolones have a wider clinical use and a broader spectrum of antibacterial activity including gram-positive and gram-negative aerobic and anaerobic organisms. Some of the newer fluoroquinolones have an important role in the treatment of community-acquired pneumonia and intra-abdominal infections. The serum elimination half-life of the fluoroquinolones range from 3 -20 hours, allowing for once or twice daily dosing. A lot of imagination is required in writing. People may think that writing on Chronic Bronchitis is very easy; on the contrary, knowledge and imagination has to be merged to create an interesting composition.

Fluoroquinolones are Approved for Use Only in People Older Than 18

They can affect the growth of bones, teeth, and cartilage in a child or fetus. The FDA has assigned fluoroquinolones to pregnancy risk category C, indicating that these drugs have the potential to cause teratogenic or embryocidal effects. Giving fluoroquinolones during pregnancy is not recommended unless the benefits justify the potential risks to the fetus. These agents are also excreted in breast milk and should be avoided during breast-feeding if at all possible. With people wanting to learn more 6 ways to cure bronchitis, it has provided the necessary incentive for us to write this interesting article on Bronchitis! Very Happy.

The fluoroquinolones are a family of synthetic, broad-spectrum antibacterial agents with bactericidal activity. The parent of the group is nalidixic acid, discovered in 1962 by Lescher and colleagues. The first fluoroquinolones were widely used because they were the only orally administered agents available for the treatment of serious infections caused by gram-negative organisms, including Pseudomonas species. Very Happy.

Fourth Generation

The fourth-generation fluoroquinolones add significant antimicrobial activity against anaerobes while maintaining the gram-positive and gram-negative activity of the third-generation drugs. They also retain activity against Pseudomonas species comparable to that of ciprofloxacin. The fourth-generation fluoroquinolones include trovafloxacin (Trovan). Wink

Urinary tract infections (norfloxacin, lomefloxacin, enoxacin, ofloxacin, ciprofloxacin, levofloxacin, gatifloxacin, trovafloxacin) Lower respiratory tract infections (lomefloxacin, ofloxacin, ciprofloxacin, trovafloxacin) Skin and skin-structure infections (ofloxacin, ciprofloxacin, levofloxacin, trovafloxacin) Urethral and cervical gonococcal infections (norfloxacin, enoxacin, ofloxacin, ciprofloxacin, gatifloxacin, trovafloxacin) Prostatitis (norfloxacin, ofloxacin, trovafloxacin) Acute sinusitis (ciprofloxacin, levofloxacin, gatifloxacin, moxifloxacin (Avelox), trovafloxacin) Acute exacerbations of chronic bronchitis (levofloxacin, sparfloxacin (Zagam), gatifloxacin, moxifloxacin, trovafloxacin) Community-acquired pneumonia (levofloxacin, sparfloxacin, gatifloxacin, moxifloxacin, trovafloxacin)

Second Generation

The second-generation fluoroquinolones have increased gram-negative activity, as well as some gram-positive and atypical pathogen coverage. Compared with first-generation quinolones, these drugs have broader clinical applications in the treatment of complicated urinary tract infections and pyelonephritis, sexually transmitted diseases, selected pneumonias and skin infections.

Because of concern about hepatotoxicity, trovafloxacin therapy should be reserved for life- or limb-threatening infections requiring inpatient treatment (hospital or long-term care facility), and the drug should be taken for no longer than 14 days. Surprised

All of the fluoroquinolones are effective in treating urinary tract infections caused by susceptible organisms. They are the first-line treatment of acute uncomplicated cystitis in patients who cannot tolerate sulfonamides or TMP, who live in geographic areas with known resistance > 10% to 20% to TMP-SMX, or who have risk factors for such resistance. We have not actually resorted to roundabout means of getting our message on Bronchitis through to you. All the matter here is genuine and to the point.

Anything Chronic is Considered to be a Persistent, Recurrent and Lasting Condition

While chronic bronchitis has often been associated with allergies and/or asthma, there are many other causes that can trigger a bronchial infection. Asthma as we know is a lung disease that is characterized by asthmatic events triggered by a variety of factors which cause a constriction of the bronchial tubes and air passages.

According to the Mayo Clinic, a well regarded medical facility, bronchitis and the resulting cough can also be caused from stomach acid irritating for food pipe or esophagus. This is better known as acid reflux disease.

Exposure to chemical fumes and odors may compromise an otherwise healthy respiratory system. This in turn can lead to sensitivity to other environmental factors like dust, but also both primary and secondary tobacco smoke. While the validity of the effects of secondhand smoke are continue to be debated, it has been shown to be an important breathing factor for those with a compromised respiratory system. All of these factors can contribute to the chronic cough experienced by many asthma, allergy and bronchitis sufferers. Quality is better than quantity. It is of no use writing numerous pages of nonsense for the reader. Instead, it is better to write a short, and informative article on specific subjects like Bronchitis Causes. People tend to enjoy it more.

Chronic cough, wheezing, breathing difficulties and a tight chest have also been associated with the common smoker's cough. This is unfortunate as there are many environmental factors that can contribute to an infection and caused these types of symptoms. What are the real causes of bronchitis? was written with the intention of making it very memorable to its reader. Only then is an article considered to have reached it's objective. Surprised.

One Such Environmental Factor is Dust

While dust is a common substance found everywhere, it's especially problematic for those of us who may have a compromised respiratory system. A less than ideal breathing tract is found in people suffering with asthma, many allergies and yes even smokers. What's been ignored in many cases however, is that exposure to chemicals can cause a sensitivity to environmental factors such as dust. We have used clear and concise words in this article on Chronic Bronchitis informatioin any misunderstandings and confusions that can be caused due to difficult words.

Acid Reflux can Now be Successfully Treated With Many Medications

If you think that someone you know may be suffering from a chronic cough caused by bronchitis or possibly asthma, it's important to understand the lifestyle implications this may involve. The primary focus however, should be to get an accurate diagnosis from a qualified respiratory or pulmonary medical professional.

Has Long Been Known that Smoking and Lung Cancer are Causally Linked

After having discovered this association though, much has been made of the heightened incidence of other forms of cancer caused by of smoking. I am going to highlight the data that reiterates the claims and suggest that the evidence is not so strong for other forms of cancer being causally linked with smoking. The evidence is analysed from the mortality statistics for the UK in 2002. Idea

All in all, there were over 114,000 premature deaths in 2002 from cigarette smoking, mostly from cancer, but also from heart disease and pulmonary (lung) disease. The best way to improve ones chances of not suffering from a shortened life and succumbing to one of the diseases mentioned in this article is by quitting smoking once and for all. Benefits have been clearly documented and the sooner smokers quit, the bigger the benefits of quitting become on their life expectancy. Indeed, smokers who quit before they reach thirty, statistically negate virtually all the ill health effect of smoking and can generally expect to live as long as a non-smoking contemporary.

Emphysema is the destruction of the lung leading to loss of surface area, alveoli (air sacks in the lungs) and the loss of elasticity. Chronic bronchitis manifests itself through swollen bronchii and over production of mucus within the lung. It is characterised by daily coughing, bringing up sputum. Both emphysema and bronchitis lead to slow, debilitating and frustrating deaths for their victims. Delaware state university this end product on Emphysema Bronchitis. It was really worth the hard work and effort in writing so much on Emphysema Bronchitis.



  • Kidney cancer is another cancer where smokers are seen less frequently than non-smokers in the statistics.
  • The next disease we shall look at is the non-cancerous, chronic obstructive pulmonary disease or COPD.
  • The disease manifests itself mainly in two forms, being emphysema and chronic bronchitis.



Oesophageal cancer deaths numbered just under 5,000 and the deceased were found to be 66% smokers, 71% and 65% men to women respectively; again another clear link that smoking and oesophageal cancer are linked. Enhancing your vocabulary is our intention with the writing of this article on Bronchitis Emphysema. We have used new and interesting words to achieve this. Very Happy.


Will work through the statistics because 26% of the population are smokers and so one might reasonably assume that any incidence of cancer where less than 26% of sufferers are smokers may have other more prevalent causes than smoking. We have not included any imaginary or false information on Chronic Bronchitis Emphysema here. Everything here is true and up to the mark!


Deaths from COPD in 2002 in the UK numbered 28,500 of which 84% were smokers demonstrating a clear link between the inhalation of tobacco smoke and the disease as is the case with lung cancer. Using our imagination has helped us create a wonderful article on Emphysema Chronic Bronchitis. Being imaginative is indeed very important when writing about Emphysema Chronic Bronchitis! Embarassed

Pediatric Antibiotic Use: a Focused Review of Fluoroquinolones and





Some sources suggest that pneumonia is more likely to kill in smokers but only 17% of the 36,000 fatal pneumonia cases were found in smokers suggesting this is not the case. Aiming high is our motto when writing about any topic. In this way, we tend to add whatever matter there is about Chronic Bronchitis Emphysema, rather than drop any topic.

Death from cancer of the upper respiratory tract was found at a rate of 66% in smokers, nearly three times the percentage of smokers. Note though that women sufferers represented half of their cohort compared with three quarters of men, suggesting upper respiratory cancer is more likely in men than in women smokers. Even the beginner will get to learn more about Chronic Bronchitis after reading this article. It is written in easy language so that everyone will be able to understand it.



  • Stomach cancer took 1,650 lives in 2002 but is found in 35% of men compared with only 11% of female smokers.
  • It is reasonable therefore to draw the same conclusion about the causes as for bladder cancer between men and women.
  • Suppressing our knowledge on Bronchitis Emphysema is not our intention here.
  • In fact, we mean to let everyone know more about Bronchitis Emphysema after reading this! Wink



Firstly, we will deal with the cancer doane college get underway with the 33,600 deaths from lung cancer. 84% of these deaths were in smokers. This means that the average 26% of the smoking population yielded more than three times the proportion of deaths ' a clear link. Wink



  • Pancreatic cancer is another cancer that is less prevalent in smokers than the general population.
  • Indeed 20% of men and 26% of women dying from the disease in 2002 were smokers, suggesting parity with women and a disparity with men.
  • It may be reasonable therefore to assume that there are other contributory factors in male pancreatic cancers.
  • This is a dependable source of information on Emphysema Bronchitis.
  • All that has to be done to verify its authenticity is to read it!



Next, bladder cancer takes over 1,800 lives per year of which 37% are found to be smokers. However, only 19% of female cases were smokers compared with 47% of male cases. It is fair to assume that there are other factors more prevalent in female bladder cancer other than smoking but the link is clear in men. We have avoided adding flimsy points on Bronchitis, as we find that the addition of such points have no effect on Bronchitis.
