Levofloxacin (1), the levo-isomer or the (5)-enantiomer of ofloxacin, received FDA approval in 1996 (Fish, 2003 Hurst et al., 2002 Mascaretti, 2003 Norrby, 1999 North et al., 1998). The initial approval covered community-acquired pneumonia, acute bacterial exacerbation of chronic bronchitis, acute maxillary sinusitis, uncomplicated skin and skin structure infections, acute pyelonephritis, and complicated urinary tract infections (North et al., 1998). Four years later, the levofloxacin indication list grew to include community-acquired pneumonia caused by penicillin-resistant Streptococcus pneumoniae. In addition, in 2002, nosocomial (hospital-acquired) pneumonia caused by methicillin-susceptible Staphylococcus aureus, Pseudomonas aeruginosa, Serratia marcescens, Haemophilus influenzae, Kliebsella pneumoniae, and Escherichia coli was added (Hurst et al., 2002). Finally in 2004, LVX was approved as a post-exposure treatment for individuals exposed to Bacillus anthracis, the microbe that causes anthrax, via inhalation (FDA, 2004). 

Otitis media, acute bronchitis, acute exacerbations of chronic bronchitis, pharyngitis, tonsillitis, and uncomplicated UTIs PO 400 mg/day as a single dose or in 2 divided doses. 

We must accept the possibility that exposure to CS of a patient with chronic bronchitis and emphysema may result In an acute bronchitis being superimposed on the chronic condition. Again this does not appear to differ from the situation when such an acute exa-... 

Most cases of acute bronchitis are viral where bacteria are responsible the usual pathogens are Streptococcus pneumoniae and/or Haemophilus influenzae. It is questionable if there is role for antimicrobials in uncomplicated acute bronchitis but... 

In comparative trials involving commonly used regimens, levofloxacin had equivalent if not greater activity in the treatment of community-acquired pneumonia, acute bacterial exacerbations of chronic bronchitis, acute bacterial sinusitis, acute pyelonephritis, and complicated urinary tract infection (5). 

Corticosteroids are anti-inflammatory drugs that can be used in asthma to reduce airway hyper-responsiveness and to decrease bronchial oedema and mucus secretion. They are effective in the late phase reaction and reduce the intensity of allergic reactions. They are used in emergency treatment of severe acute attacks, for the treatment of mild to moderate attacks and prophylactically to prevent attacks. Corticosteroids can be useful in reducing acute exacerbations of chronic bronchitis. 

Loracarbef, a synthetic beta lactam antibiotic of the car-bacephem class (200 to 400 mg p.o. q. 12 hours), is used in the treatment of secondary bacterial infections of acute bronchitis, acute bacterial exacerbations or chronic bronchitis, of pneumonia, pharyngitis, tonsillitis, sinusitis, acute otitis media, uncomplicated skin and skin-structure infections, impetigo, uncomplicated cystitis, and in uncomplicated pyelonephritis. 

Telithromycin is a ketolide, which interferes with microbial protein synthesis. It is indicated in the treatment of acute bacterial exacerbation of chronic bronchitis, acute bacterial sinusitis, and community-acquired pneumonia caused by strains of susceptible organisms. 

Moderate to high toxicity toxic route—inhalation LD50 data not available in humans, acute toxic symptoms can be bronchitis, wheezing, congestion in chest, and pulmonary edema—similar to other aromatic diisocyanates low oral toxicity LD50 intravenous (mice) 5.6 mg/kg exposure limits TLV-TWA (relative to diisocyanate) 0.0327 mg/m ... 

Actions and Uses.—Internally —In excessive doses, a narcotic-acrid poison in medicinal doses, sedative, anodyne, and antispasmodic. In whatever doses it is administered, or by whatever channel it enters the circulation, it causes dilatation of the pupil. Given in colic, acute and chronic rheumatism, bronchitis, infiuenza, and in cases of sore throat and cough which often accompany or succeed this last-named disease. 

Beta 2 adrenergic agonists Acute and chronic bronchial asthma, emphysema, bronchitis, acute hypersensitive (allergic) reaction to drugs, delays delivery in premature labor, dysmenorrhea Common drug examples ... 

The hallmark of an inflammatory response in the lung is the presence of infiltrating leukocytes. This process can occur in the context of a variety of disorders, including trauma, infection, autoimmune diseases, idiopathic interstitial pneumonias, asthma, chronic bronchitis, acute respiratory distress syndrome (ARDS), exposure to environmental/occupational noxious agents, cancer, aUograft rejection, and ischemia-reperfusion injury. The course of inflammation in these disease states is defined by the delicate balance and nature of inflammatory mediators expressed in the context of lung inflammation, and the specific leukocyte populations recmited in response to lung injury.
