Norfloxacin: Side Effects

In a double-blind, multicenter study 171 patients who had acute pyelonephritis were given intravenous cefuroxime for 2-3 days, followed by ceftibuten 200 mg bd or norfloxacin 400 mg bd for 10 days. There were fewer bacterial relapses after oral norfloxacin than ceftibuten. Adverse events were reported by 47% of the patients taking ceftibuten and by 38% of those taking norfloxacin. This difference was not significant, but diarrhea or loose stools occurred more often with ceftibuten.

Antimicrobial Regimen Selection

A generally accepted systematic approach to the selection and evaluation of an antimicrobial regimen is shown in Table Systematic Approach for Selection of Antimicrobials. An «empiric» antimicrobial regimen is begun before the offending organism is identified, while a «definitive» regimen is instituted when the causative organism is known. The use of combinations to prevent the emergence of resistance is widely applied but not often realized. The only circumstance where this has been clearly effective is in the treatment of tuberculosis.

Antimicrobial therapy: general principles

A wide variety of antimicrobial agents is available to treat established infections caused by bacteria, fungi, viruses, or parasites. This section will cover the general principles of antimicrobial therapy and will also include illustrative clinical problems to emphasize proper decision-making in using antimicrobials.

Toxicity of Antimicrobial Therapy

The mechanisms associated with common adverse reactions to antimicrobials include dose-related toxicity that occurs in a certain fraction of patients when a critical plasma concentration or total dose is exceeded, and toxicity that is unpredictable and mediated through allergic or idiosyncratic mechanisms. For example, certain classes of drugs such as the aminoglycosides are associated with dose-related toxicity.

Buy Bactrim (Co-trimoxazole) 400mg/800mg No Prescription

Co-trimoxazole is used for the treatment of urinary tract infections (UTIs) caused by susceptible strains of E. coli, Proteus (indole-positive or -negative), Klebsiella, Morganella morganii, or Enterobacter. Co-trimoxazole, given in single doses, as 3-day therapy, or for 7-10 days, is effective in the treatment of acute uncomplicated UTIs. Some clinicians consider a 3-day regimen of co-trimoxazole the treatment of choice for the empiric treatment of acute uncomplicated UTIs. Co-trimoxazole also is used for the treatment of acute complicated UTIs (e.g., UTIs associated with abnormalities of the urinary tract or neurogenic bladder), but other anti-infectives are preferred by most clinicians.

Purchase Clarithromycin (Biaxin) No Prescription 250/500mg

Clarithromycin is used orally for the treatment of pharyngitis and tonsillitis, mild to moderate respiratory tract infections (acute bacterial exacerbation of chronic bronchitis, acute maxillary sinusitis, community-acquired pneumonia), uncomplicated skin and skin structure infections, and acute otitis media caused by susceptible organisms.

Buy Azithromycin (Zithromax) Without Prescription 250/500mg

Oral azithromycin also is used for the treatment of urethritis or cervicitis caused by Chlamydia trachomatis or Neisseria gonorrhoeae, and for the treatment of chancroid caused by Haemophilus ducreyi. Azithromycin is used orally for the treatment of disseminated infections caused by Mycobacterium avium complex (MAC) in patients with human immunodeficiency virus (HIV) infection and for prevention of disseminated MAC infection (both primary and secondary prophylaxis) in HIV-infected individuals. Azithromycin is used orally in children for the treatment of acute otitis media, community-acquired pneumonia, and pharyngitis or tonsillitis caused by susceptible organisms.

Loracarbef (Lorabid Capsules 200, 400 mg)

Carbacephems are b-lactam antibiotics structurally and pharmacologically related to cephalosporins; however, carbacephems contain a methylene group instead of sulfur in the dihydrothiazine ring of the cephalosporin nucleus, resulting in a tetrahydropyridine ring. This structural modification does not affect microbiologic activity, but substantially improves stability in aqueous solution and in serum, plasma, and other body fluids. Loracarbef is the carba analog of cefaclor, a second generation cephalosporin. SumMon® (see Users Guide).

Ceftibuten

Ceftibuten is used orally for the treatment of mild to moderate respiratory tract infections (i.e., acute exacerbations of chronic bronchitis) caused by susceptible bacteria. The drug also is used orally for the treatment of acute otitis media caused by susceptible bacteria and pharyngitis and tonsillitis caused by Streptococcus pyogenes (group A b-hemolytic streptococci). Oral ceftibuten is used for the treatment of acute exacerbations of chronic bronchitis caused by susceptible Streptococcus pneumoniae (penicillin-susceptible strains only), Haemophilus influenzae (including b-lactamase-producing strains), or Moraxella (formerly Branhamella) catarrhalis (including b-lactamase-producing strains.

Buy Vantin (Cefpodoxime) Without Prescription 200mg

Cefpodoxime proxetil is used orally for the treatment of mild to moderate respiratory tract infections (i.e., acute exacerbations of chronic bronchitis, acute maxillary sinusitis, community-acquired pneumonia) caused by susceptible bacteria; the treatment of acute otitis media caused by susceptible bacteria; and the treatment of pharyngitis and tonsillitis caused by Streptococcus pyogenes (group A b-hemolytic streptococci).
