Bronchitis Antibiotika, Signs and Symptoms of Bronchitis

Bronchitis Antibiotika

The bronchi are the lining of the air tubes of the lungs. The inflammation of the bronchi is called Bronchitis. It can be the result of a cold, a sore throat or influentza. The cool air and the low temperatures in winter influence in a negative way the disease. You can be contaminated with the virus that diabetes bronchitis by breathing a polluted atmosphere or by smoking.

Another sign of chronic bronchitis is the weezing. It is produced by the bronchospasm which is represented by the contraction of the circular muscles in the wall of the bronchial tubes.If this happenes the coughing becomes less efective too. We have not included any imaginary or false information on Bronchitis Emphysema here. Everything here is true and up to the mark!

Using a microscope we can have the image of the cells in the healthy lungs. These cells looks tall, columnar and their surface is covered with cilia which are able to move creating the image of a wind blowing across a field of ripe corn. This surface covered with cilia is near the inside of the tube and it has the role to protect the lungs. This protection is possible because the movement of the cilia carry dust and other foreign materials upwards and away from the delicate air sacs from the lungs. Using our imagination has helped us create a wonderful article on Persistent Cough. Being imaginative is indeed very important when writing about Persistent Cough!

• Bronchitis takes part of the disease grouped under COPD which means chronic obstructive pulmonary disease.
  
• If the disease doesn't respond to treatment it can progress to COAD (chronic obstructive airway disease).
  
• In this case tiny lung air sacs break down to form larger air spaces.
  
• At the same time, because of this change, the surface area available for the transfer of the oxygen to the blood is much less.
  
• So the other organs are less oxygenated. the mucus block the smaller bronchial tubes which becomes inflamed.
  

The heart is also affected in Bronchitis. The right heart enlarges. There is an extra pumping power because of the increase of the resistance to blood pumped through the lungs. The consequence is the oedema which is an exaggerated accumulation of liquid in the interstitial space.

• The symptoms last for one or two weeks, but this period is longer and the Bronchitis becomes chronic in cigarette smokers.
  
• They manifest also inevitable winter flare -ups.
  
• The ciliated cells can be damaged by different external irritants such as cigarette smoke, industrial pollutants and other chemical substances.
  
• So the effect of the movement of the cilia is not giving results anymore.
  
• As a consequence the glands produce a high quantity of mucus which can't be evacuated and it is accumulated in the tubes.
  
• This is one of the causes of the persistent cough which characterizes Bronchitis.
  
• Usually this cough succeed to clear the mucus.
  
• Another way of protection of the lungs is the action of the Leucocytes whose principal role is to combat inflammatory processes.
  
• Even the beginner will get to learn more about Causes Bronchitis after reading this article.
  
• It is written in easy language so that everyone will be able to understand it.
  

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.

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.

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. Don't be surprised if you find anything unusual picture of chronic bronchitis. There has been some interesting and unusual things here worth reading. .

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.

Classification of Fluoroquinolones

As a group, the fluoroquinolones have excellent in vitro activity against a wide range of both gram-positive and gram-negative bacteria. The newest fluoroquinolones have enhanced activity against gram-positive bacteria with only a minimal decrease in activity against gram-negative bacteria. Their expanded gram-positive activity is especially important because it includes significant activity against Streptococcus pneumoniae. Having a penchant for Bronchitis led us to write all that there has been written on Bronchitis here. Hope you too develop a penchant for Bronchitis!

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. There has been an uncalculatable amount of information added in this composition on Bronchitis. Don't try counting it!

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). We would like you to leisurely go through this article on Bronchitis to get the real impact of the article. Bronchitis is a topic that has to be read clearly to be understood. .

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. Dalton state college 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 lung 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. We have included the history of Bronchitis here so that you will learn more about its history. It is only through it's history can you learn more about Bronchitis.
