Pseudomonas Aeruginosa

The genus Pseudomonas consists of a number of human pathogens, the most important of which is Pseudomonas aeruginosa. P aeruginosa is an opportunistic pathogen found widely in soil, water, and organic material, reflecting its limited nutritional requirements. A moist environment is favored. Human colonization in the community is rare, and, when it occurs, the skin, gut, and upper or lower airway are colonized.

Infection in Patients With Aids

Paeruginosa infections may occur in patients with AIDS. Risk factors for infection include a CD4 count of < 100 cells/mL3, neutropenia or functional neutrophil defects, intravascular catheterization, hospitalization, and prior use of antibiotics including ciprofloxacin or trimethoprim-sulfamethoxazole. Many cases are community acquired. Bacteremia is common, and the lung or an intravenous catheter is the most frequent portal of entry.

Ear, Nose & Throat Infections

P aeruginosa infection of the external auditory canal may be acute or may be a chronic serious infection called malignant otitis externa. Acute diffuse otitis externa is often referred to as swimmer’s ear. P aeruginosa may be part of the normal flora of the external auditory canal or may colonize the canal as a result of exposure to water.

Buy Generic Noroxin (Norfloxacin) No Prescription 400mg

Adverse effects have occurred in about 7% of patients receiving a single 800-mg oral dose of norfloxacin for the treatment of uncomplicated gonorrhea. Dizziness, nausea, and abdominal cramping are the adverse effects reported most frequently in patients receiving this single-dose regimen, and these effects have been reported in 2-3.5% of patients.

Lomefloxacin HCl

Lomefloxacin is used orally in adults for the treatment of mild to moderate lower respiratory tract infections (acute bacterial exacerbations of chronic bronchitis) and uncomplicated or complicated urinary tract infections caused by susceptible organisms. The drug also is used orally for perioperative prophylaxis in patients undergoing transrectal prostate biopsy or transurethral surgical procedures.

Order Ciloxan (Ciprofloxacin HCl) No Prescription 0.3%-5ml

Ciprofloxacin generally is well tolerated, and adverse effects of the drug are similar to those reported with other quinolone anti-infectives (e.g., norfloxacin, ofloxacin). Adverse effects have been reported in 5-14% of patients receiving ciprofloxacin, and have been severe enough to require discontinuance in 2-3.5% of patients.


Like other parenteral third generation cephalosporins (cefoperazone, cefotaxime, ceftizoxime, ceftriaxone), ceftazidime is less active than first and second generation cephalosporins against some gram-positive bacteria (e.g., staphylococci) and generally should not be used in the treatment of infections caused by these organisms when a penicillin or first or second generation cephalosporin could be used.

Cephalosporins: Cefaclor, Cefadroxil, Cefazolin, Cefdinir, and Other

Cephalosporins are semisynthetic b-lactam antibiotics that are structurally and pharmacologically related to penicillins, carbacephems (e.g., loracarbef), and cephamycins (e.g., cefotetan, cefoxitin). Cephalosporins generally are divided into 4 groups (“generations”) based on their spectra of activity. Cefaclor, cefadroxil, cefdinir, cefditoren pivoxil, cefpodoxime proxetil, cefprozil, ceftibuten, cefuroxime axetil, cephalexin, and cephradine also are used orally for the treatment of mild to moderate skin and skin structure infections caused by susceptible staphylococci or streptococci.

Lomefloxacin Hydrochloride

Lomefloxacin is a fluoroquinolone antibacterial with actions and uses similar to those of ciprofloxacin. It is given orally for the treatment of susceptible infections, including bronchitis due to Haemophilus influenzae or Moraxella catarrhalis (Branhamella catarrhalis), and urinary-tract infections.
