Acute Symptoms of Bronchitis - All about Acute Bronchitis (Part One)
Acute bronchitis can be caused by an inflammation in the bronchial tubes. These are the passages that allow air to go to the lungs, through the windpipe. The information can appear for two reasons: an irritation, the most common one can be because of smoking, or an infection.
Coughing is the first and most obvious sign that you have acute bronchitis. There are two types of cough that can accompany acute bronchitis: a dry one, or a cough that produces sputum, a substance that is like mucus and is brought from the lungs. Besides couching, if you suffer from acute bronchitis you may also have a sore throat, chest pains, fever, always be tired and you may also have problems breathing. We have omitted irrelevant information from this composition on Bronchitis Sore Throat as we though that unnecessary information may make the reader bored of reading the composition.
- Is not very easy to prevent acute bronchitis, but there are things to do where preventing is concerned.
- For people who smoke, quitting is the first thing to do if you want to protect yourself against acute bronchitis.
- Also getting shots against the flu is another must.
- Inspiration can be considered to be one of the key ingredients to writing.
- Only if one is inspired, can one get to writing on any subject especially like Bronchitis Sore Throat.
- To diagnose acute bronchitis is a little bit difficult, because of the likeness of the symptoms to other symptoms of different diseases.
- The first thing that your doctor will ask you is you have had problems with your respiratory system in the past months. like infections.
- Then he will look for sounds that can indicate him if your airways are blocked.
- For that the doctor will listen your chest using a stethoscope.
- Another way to diagnose acute bronchitis is to test the oxygen level in your blood.
You are diagnosed with acute bronchitis, you may seek a treat meant or just let it pass for itself. Most people that have acute bronchitis can get better without treatment, although they might cough for some days after the other symptoms have disappear. In some cases, couching can last up to months, often the person has been cured from caute bronchitis, because the bronchial linings still suffer from irritation. We take pride in saying that this article on Bronchitis Dry is like a jewel of our articles. This article has been accepted by the general public as a most informative article on Bronchitis Dry.
- When you catch a cold or the flu and your respiratory system becomes ill, this is the starting point for acute bronchitis.
- The infection then travels into your airways, through your throat.
- A good thing is that acute bronchitis does not last as long as pneumonia does.
- Another thing for you to know is that acute bronchitis is usually caused by some viruses, but you can get this disease because of a bacteria as well.
- Having been given the assignment of writing an interesting presentation on Bronchitis, this is what we came up with.
- Just hope you find it interesting too!
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.
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. Writing an article on Chronic Bronchitis was our foremost priority while thinking of a topic to write on. This is because Chronic Bronchitis are interesting parts of our lives, and are needed by us.
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. The results of one reading this composition is a good understanding on the topic of Chronic Bronchitis. So do go ahead and read this to learn more about Chronic Bronchitis.
.
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.
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 Remember that it is very important to have a disciplined mode of writing when writing. This is because it is difficult to complete something started if there is no discipline in writing especially when writing on Chronic Bronchitis.
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. It is only through sheer determination that we were able to complete this composition on Chronic Bronchitis. Determination, and regular time table for writing helps in writing essays, reports and articles.
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 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. It is only because that we are rather fluent on the subject of Chronic Bronchitis that we have ventured on writing something so influential on Chronic Bronchitis like this!
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. We were furnished with so many points to include while writing about Chronic Bronchitis that we were actually lost as to which to use and which to discard!
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.
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
a major risk factor of chronic bronchitis (levofloxacin, sparfloxacin (Zagam), gatifloxacin, moxifloxacin, trovafloxacin) Community-acquired pneumonia (levofloxacin, sparfloxacin, gatifloxacin, moxifloxacin, trovafloxacin)
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.
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.
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. Although there was a lot of fluctuation in the writing styles of we independent writers, we have come up with an end product on Bronchitis worth reading!
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.
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. When a child shows a flicker of understanding when talking about Bronchitis, we feel that the objective of the meaning of Bronchitis being spread, being achieved.
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 We have written a humorous anecdote on Bronchitis to make it's reading more enjoyable and interesting to you. This way you learn there is a funny side to Bronchitis too!
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 have to be very flexible when talking to children about Bronchitis. They seem to interpret things in a different way from the way we see things!
