We have evaluated the use of high-dose intravenous ciprofloxacin as monotherapy in the empirical therapy of febrile episodes in neutropenic patients during the course of a randomized trial comparing ciprofloxacin with a standard combination regimen. Sixty-four episodes of fever were studied in a high risk population of 42 patients mostly undergoing intensive chemotherapy for leukaemia. Ciprofloxacin achieved clinical responses as follows: completely successful in 39%, partially successful in 20%, and unsuccessful in 41%. Infections were microbiologically documented in 37 (58%), with Gram-positive bacteria (of which 37% were coagulase negative staphylococci and 34% were streptococci) accounting for 81% of all organisms cultured. Responses in documented infections were as follows; completely successful in 32%, partially successful in 27%, and unsuccessful in 41%. One infection-related death occurred 30 h after starting ciprofloxacin, and a further three patients died before the resolution of neutropenia. The early death was caused by fulminant infection with a ciprofloxacin-resistant Pseudomonas aeruginosa. No other ciprofloxacin resistance was seen amongst eight Gram-negative isolates. There was no evidence of emerging ciprofloxacin resistance during the course of the study. Ciprofloxacin was associated with a low incidence of adverse events with skin rash (five cases) and nausea (one case) being reported as possibly or probably related to ciprofloxacin. We conclude that high-dose intravenous ciprofloxacin may be safely employed as monotherapy in the empirical treatment of febrile episodes in neutropenic patients. It has the additional advantages of twice daily administration, the availability of intravenous and oral presentations, and absence of cross-allergy in beta-lactam antibiotic hypersensitive patients.

Data from 1,878 courses of intravenous ciprofloxacin therapy, administered to 1,869 patients in 59 clinical trials, were analyzed for drug safety. The 985 men and 884 women had a mean age of 50 years, and more than one third were over 60 years of age. An overwhelming majority had at least one accompanying systemic illness, and the condition of more than half the patients was only fair or poor at the onset of therapy. Ciprofloxacin was administered in a unit dose of either 200 mg (68 percent of the patients) or 300 mg (28 percent) by intravenous infusion, generally over 30 minutes every 12 hours, at a mean daily dosage of 456 mg. The duration of intravenous therapy ranged from one to 57 days, with a mean of seven days; over 1,000 patients were treated for more than five days. Adverse events considered probably or possibly related to intravenous ciprofloxacin were reported in 15.8 percent of the courses; therapy was discontinued prematurely in 3 percent. Local reactions at the site of infusion were the most common, occurring in 4.4 percent of the courses. Changes in blood chemistry values (4.1 percent) included increases in alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Reports of adverse effects referable to the gastrointestinal tract (3.0 percent) were primarily nausea and diarrhea. Central nervous system reactions (1.8 percent) included convulsive seizures, headache, and dizziness. In comparative trials, events considered probably or possibly drug related were reported for 17.3 and 13.6 percent of the ciprofloxacin- and ceftazidime-treated patients, respectively. The incidence of adverse events other than local reactions at the infusion site was not significantly different between the ciprofloxacin- and ceftazidime-treated patients (12.7 percent versus 11.0 percent, p greater than 0.2).

Twenty-seven patients with chronic osteomyelitis were treated with oral ciprofloxacin, 500 mg (13 patients) or 750 mg (13) twice daily and one patient was treated with 300 mg twice daily intravenously. Treatment was given for 17-189 days (mean 69). Twenty-three patients had prosthetic implants, 16 patients had infections caused by one bacterium and 11 had polymicrobial infections. The predominant organisms were strains of Enterobacteriaceae, Pseudomonas aeruginosa and Staphylococcus aureus. Cure was obtained in 20 patients and improvement in four. Three patients failed to respond to therapy. Concentrations of ciprofloxacin, measured in pus 1 h after 500 mg orally ranged from 0.6-1.3 mg/l, whilst 2 h after 750 mg orally concentrations of 2.4-6.8 mg/l were found. Sterilization of pus and closure of infected wounds or draining sinuses were observed within four weeks of treatment in the majority of patients. Ciprofloxacin was well tolerated in 26 patients, whilst one had severe nausea after oral administration.

Ciprofloxacin was administered orally to 48 patients with 24 Pseudomonas aeruginosa infections and 13 other infections caused by cephalothin-resistant gram-negative bacilli. The types of infections treated included those of skin or skin structure, bone, urinary tract, and respiratory tract. In 83% of P. aeruginosa infections, a favorable clinical outcome occurred, compared with 85% for all infections. Failure to achieve a cure correlated with the emergence of resistant P. aeruginosa and Acinetobacter calcoaceticus strains in four instances and superinfection with Candida (two cases) and Streptococcus (two cases) species. Therapy was discontinued in three patients because of the development of nausea. Ciprofloxacin appears to be safe and effective in the therapy of infections caused by resistant gram-negative bacilli.

One hundred and sixty-four male patients suffering from urethral gonorrhoea were treated in an open randomised trial with either 250 mg (n = 85) or 500 mg (n = 79) ciprofloxacin administered in one tablet. Cure rates in both groups were 100%. Postgonococcal urethritis was observed in 31 of 85 (36%) patients in the first group, and in 21 of 79 patients (27%) in the second group. Side-effects were minor, occurring in four patients in the 250 mg group (4.7%) and in seven in the 500 mg group (8.9%). The side-effects consisted of nausea, diarrhoea and headache. Ciprofloxacin would appear to be a very effective drug in the treatment of urethral gonorrhoea in males.

The clinical efficacy and the safety of ciprofloxacin was studied in 92 patients (aged 26 to 83 years; mean 57.5 years) affected by urinary tract infections (UTI) and respiratory tract infections (RTI) suffering also with various liver diseases. Ciprofloxacin was given orally at different dose regimens: 500 mg b.i.d. (22 cases), 250 mg b.i.d. (20 cases), 500 mg s.i.d. (20 cases) for the treatment of UTIs; 500 mg b.i.d. (ten cases) and 250 mg b.i.d. (20 cases) for the treatment of RTIs. The doses were not correlated to the severity of the infections. Patients were treated for five to 15 days. All the bacteria isolated from sputum or urine before treatment were sensitive to ciprofloxacin (MIC range less than or equal to 0.015 mg/l to 8 mg/l). The clinical and bacteriological responses were favourable in a high percentage of patients both for RTIs and UTIs, irrespective of the dose. Side effects were infrequent (7%) and mild (nausea, gastralgia, oral candidosis), never requiring the interruption of the treatment. No change in the blood chemistry tests was observed at any dose.

Ciprofloxacin is a new fluorinated quinolone antibiotic with high activity against a wide spectrum of gram-positive and gram-negative bacteria, including methicillin-resistant Staphylococcus aureus, Enterobacteriaceae, and Pseudomonas aeruginosa. Clinical trials using the oral preparation of ciprofloxacin have demonstrated its effectiveness in a wide variety of infections. In addition, extensive clinical trials with the intravenous preparation are underway. In vitro and in vivo studies with ciprofloxacin have reported the incidence of resistant organisms to be very low. In addition, the incidence of ciprofloxacin-related side effects throughout its clinical trials has been minimal. Most reports of side effects have been related to the gastrointestinal tract, such as nausea or vomiting. The incidence of adverse experiences in worldwide clinical trials has been reported to be approximately 6.4 percent.

Thirty two patients with proven chronic bacterial prostatitis were treated with ciprofloxacin 500 mg twice daily orally for four weeks. The causative organisms, cultured from prostatic fluid were Enterobacteriaceae (19 patients), enterococci (9), staphylococci (4), streptococci (3), non-fermentative Gram-negative rods (2) and anaerobic bacteria (9). Nineteen patients had pure cultures, 13 mixed cultures. The susceptibility of all organisms to ciprofloxacin, sulfamethoxazole, trimethoprim and doxycyclin was determined by agar dilution. The effect of therapy was measured by clinical parameters and by repeated cultures of prostatic fluid during and after therapy up to six months. Clinical cure (at one month after therapy) was obtained in 22 patients, improvement in seven; two patients did not respond, one patient had to stop during therapy because of severe nausea. No other side effects were noted. Ciprofloxacin may be a useful alternative drug in the treatment of prostatitis.

Ciprofloxacin is a new quinolone antimicrobial agent with activity against a broad spectrum of gram-negative and gram-positive organisms, including Pseudomonas aeruginosa and methicillin-resistant strains of staphylococci. The efficacy and safety results of 80 clinical studies of the oral form of ciprofloxacin are reported. Drug safety was assessed in 2236 courses in 2203 adult patients treated primarily in the United States. Data from 1676 courses were suitable for analysis of drug efficacy. The unit dose for most patients ranged from 250 mg to 750 mg (median, 500 mg), usually given every 12 hours. The duration of treatment ranged from 3 to 231 days (median, 10 days). Predominant among 1722 infections were those of the urinary tract (43%), skin structures (29%), and respiratory tract (19%); the remainder were bone and joint infections (5%), bacteremias (2%), and intra-abdominal (1%), gastrointestinal (1%), and pelvic infections (less than 1%). Signs and symptoms of infection resolved in 79% of all cases; a further 15% improved, and 5% failed to improve. Pathogens were eradicated in 89% of urinary tract infections and persisted in 5%; 80% of patients still had sterile urine at the 3-to 6-week follow-up. In 81% of nonurinary tract infections, pathogens were eradicated; they persisted in 11%, and superinfection occurred in less than 5%. After treatment, 89% of the 2253 causative organisms were eradicated and 2% were reduced to clinically insignificant counts; 8% persisted. Of 411 isolates of P. aeruginosa, 77% were eradicated, as were 97% of 421 Escherichia coli and 80% of 248 Staphylococcus aureus isolates. Also eradicated were 95% of 166 Klebsiella, 96% of 139 Proteus mirabilis, 100% of 20 other Proteus, 94% of 123 Enterobacter, 100% of 68 Haemophilus influenzae, 96% of 49 Citrobacter, 89% of 45 Serratia, 95% of 41 Streptococcus pneumoniae, 91% of 43 Salmonella, 100% of 38 Morganella morganii, and 100% of 35 Providencia isolates. Adverse reactions were judged probably or possibly drug-related in 14.8% of courses; drug treatment had to be stopped prematurely in 3.5%. The most frequent reactions were gastrointestinal complaints (chiefly nausea, diarrhea, and vomiting), metabolic disorders (elevated SGOT, SGPT, serum creatinine, or blood urea nitrogen), and nervous system effects (dizziness, light-headedness, restlessness, tremor, and headache). Crystalluria, judged to be related to ciprofloxacin, occurred in two patients.(ABSTRACT TRUNCATED AT 400 WORDS)

This review summarizes adverse reactions probably or possibly attributable to oral ciprofloxacin therapy in worldwide clinical experience involving over 6500 patients. In Europe and Japan the overall incidence of adverse reactions amongst patients receiving ciprofloxacin is reported to be 3.0% and 6.5%, respectively. An increased incidence (13.4%) has been reported from the U.S.A., possibly relating to the use of higher dosages. Very few reactions have necessitated withdrawal of treatment. The most common adverse effects involve the gastro-intestinal system (2-8% of patients treated) and usually comprise nausea, vomiting, diarrhoea and abdominal discomfort. CNS effects are seen in 1-4% of patients but are usually minor dizziness or mild headache only. Hypersensitivity reactions, most commonly skin rashes or pruritus, affect about 1% of patients. There is little evidence of significant haematological or biochemical toxicity, other than a few reports of transient neutropenia and the finding, in a minority of clinical studies, of equally transient, usually trivial and invariably reversible elevations of serum aminotransferases. Serious, ciprofloxacin-related toxicity has been observed in only three patients: one who developed pseudomembranous colitis, another who developed interstitial nephritis and a third who had a grand-mal convulsion during concomitant administration of theophylline. Ciprofloxacin appears to have an excellent safety profile.
