Abstract

Fluoroquinolones are bactericidal agents that exhibit AUC/MIC dependent killing. In general, they are effective against Gram-negative organisms and some mycobacteria. Ciprofloxacin is the members of this group and its bactericidal action involves the impeding of enzyme topoisomerase II and IV. In human beings, this drug is recommended for a variety of infections including typhoid fever,chronic bacterial prostatitis, lower respiratory tract infections, skin infections, urinary tract infections, acute exacerbations of chronic bronchitis, complicated intra-abdominal infections, infectious diarrhea, and uncomplicated cervical as well as urethral gonorrhea.The drug is as effective in animals as in humans, and is therefore used in animals as well. According to European health law and National Office of Animal Health (NOAH), UK, the statutory withdrawal period for veterinary medicinal products must not be less than 28 days for meat from poultry. The chicken used for meat purpose usually is of the age between 6 to 8 weeks, therefore the use of the drug must be discontinued by the age of 2 weeks. Whereas the age of chick at which it usually develops indicated diseases, is 3 weeks. In this situation, it is not possible to attain a withdrawal period of 28 days. Based on these observations, ciprofloxacin use may not be recommended in poultry for treatment of diseases as it may cause unnecessary exposure to humans while utilizing poultry meat and may lead to the development of drug resistance

ABSTRACT… Fluoroquinolones are bactericidal agents that exhibit AUC/MIC dependent
killing. In general, they are effective against Gram-negative organisms and some mycobacteria.
Ciprooxacin is the members of this group and its bactericidal action involves the impeding of
enzyme topoisomerase II and IV. In human beings, this drug is recommended for a variety of
infections including typhoid fever,chronic bacterial prostatitis, lower respiratory tract infections,
skin infections, urinary tract infections, acute exacerbations of chronic bronchitis, complicated
intra-abdominal infections, infectious diarrhea, and uncomplicated cervical as well as urethral
gonorrhea.The drug is as effective in animals as in humans, and is therefore used in animals
as well. According to European health law and National Ofce of Animal Health (NOAH), UK,
the statutory withdrawal period for veterinary medicinal products must not be less than 28 days
for meat from poultry. The chicken used for meat purpose usually is of the age between 6 to 8
weeks, therefore the use of the drug must be discontinued by the age of 2 weeks. Whereas the
age of chick at which it usually develops indicated diseases, is 3 weeks. In this situation, it is not
possible to attain a withdrawal period of 28 days. Based on these observations, ciprooxacin
use may not be recommended in poultry for treatment of diseases as it may cause unnecessary
exposure to humans while utilizing poultry meat and may lead to the development of drug
resistance.

INTRODUCTION
Ciprooxacin belongs to the group of drugs
called uoroquinolones1. Introduction of the rst
uorinated quinolone, noroxacin lead to the
development of other members of this group2,
such as ciprooxacin, which has wide clinical
applications, better safety prole and good in
vitro effectiveness against resistant pathogenic
organisms as compared to other classes of
antibiotics3. Fluoroquinolones are bactericidal
agents and exhibit AUC/MIC dependent killing.In
general, they are effective against Gram-negative
organisms and some mycobacteria4. The
molecular formula of Ciprooxacin is C17H18FN3O3
having a molar mass of of 331.4g/mol. Chemically
it is 1-cyclopropyl-6-uoro-1,4-dihydro-4-oxo-
7-(1-piperazinyl)-3-quinolinecarboxylic acid5.
Physically the drug exists in crystalline form at
room temperature with a light yellow color6. The
structural formula of ciprooxacin is7

Pharmacokinetic properties of ciprooxacin
Ciprooxacin is well absorbed from gastrointestinal
tract after oral administration with a serum
protein binding of about 20 to 40%. The absolute
bioavailability of the drug is almost 70% and it is
not affected by rst pass metabolism8.
The drug is distributed through out the body
after oral administration. The tissue concentration
generally exceeds serum concentration
especially in genital tissuesincluding prostate.
The drug is found in active form, in nasal and
bronchial secretions, skin blister uid, mucosa of
the sinuses, sputum, saliva, lymph, prostatic
secretions, peritoneal uid and bile9,10. A deep
analysis reveals the noticeable amounts of
ciprooxacin incartilage, and bones, fats, lungs,
skin and skeletal muscles11, while less amount of
drug has been detected in vitreous humor of the
eyes12.This feature of deep penetration makes the
use of this drug questionable in meat producing
animals.
Upon urine analysis, four metabolites
(approximately 15% of oral dose) of ciprooxacin
have been identied13. It is observed that
ciprooxacin impedes human cytochrome P450
1A2 (CYP1A2) mediated metabolism, therefore
co-administration of this drug with other drugs
which are primarily metabolized by CYP1A2
may result in increased plasma concentrations
of the later drugs and has the potential to cause
clinically signicant adverse events14.
In individuals with normal renal function,
ciprooxacin’s elimination half-life in the serum is
about 4 hours. Approximately 40 to 50% of oral dose
of the drug is excreted in the urine as unchanged15.
Concurrent use of ciprooxacin with probenecid
(a drug to treat gout and hyperuricemia)can lead
to 50% increase in concentration of ciprooxacin
in systemic circulation because of its reduced
renal clearance16,17.
Pharmacodynamic properties of ciprooxacin
Antibacterial (bactericide) action of ciprooxacin is
exhibited by deterring the enzymes topoisomerase
IV and topoisomerase II (DNA gyrase). These
enzymes are the basic requirements of bacteria
for DNA repair, transcription, recombination, and
replication18.
Antimicrobial spectrum
Antibacterial spectrum of ciprooxacin includes;
Streptococcus pneumoniae (penicillin susceptible
isolates only), Enterococcus faecalis (vancomycin-
susceptible isolates only), Staphylococcus
epidermidis (methicillin-susceptible isolates only),
Staphylococcus saprophyticus, Staphylococcus
aureus (methicillin-susceptible isolates only),
Streptococcus pyogenes, Gram-negative
bacteria, Citrobacterkoseri (diversus), Proteus mi
rabilis,Citrobacterfreundii,Enterobacter cloacae,
Escherichia coli, Neisseria gonorrhoeae,Morgan
ellamorganii,Haemophilusinuenza,Haemophilus
para inuenzae,Klebsiella pneumonia, Moraxella
catarrhalis, Campylobacter jejuni, Proteus
vulgaris, Providencia rettgeri, Providencia stuartii,
Pseudomonas aeruginosa, Salmonella typhi,
Serratia marcescens, Shigella boydii, Shigella
dysenteriae, Shigella exneri, Shigella sonnei.19
Drug Resistance
Microorganisms resistant to penicillins,
cephalosporins, aminoglycosides, macrolides,
and tetracyclines may be susceptible to
uoroquinolones, including ciprooxacin because
of different bactericidal mechanism20. Even then,
resistance to uoroquinolones is possible either
by decreased outer membrane permeability,
mutations in the DNA gyrases, or drug efux. In
vitro studies have shown that, resistance develops
slowly with the prolong exposure to low doses of
ciprooxacin by multiple step mutations21.
Clinical Uses In humans
Besides the prophylactic use, ciprooxacin
is indicated for the treatment of infections
like; typhoid fever (enteric fever), urinary tract
infections, chronic bacterial prostatitis, for the
treatment of acute exacerbations of chronic
bronchitis, skin and skin structure infections,
complicated intra-abdominal infections, acute
uncomplicated cystitis in females, lower
respiratory tract infections, acute sinusitis, bone
and joint infections, infectious diarrhea, as well as

uncomplicated cervical and urethral gonorrhea
caused by neisseria gonorrhoeae22-27.
Uses in Poultry
In veterinary medicines, ciprooxacin is often
recommended for respiratory tract infections,
gastrointestinal tract infections and urinary tract
infections caused by Campylobacter, E. coli,
Haemophilus, Mycoplasma, Pasteurella and
Salmonella species28. These diseases start
appearing in poultry from the age of three days to
several months, on an average the most vulnerable
age is 3 weeks for respiratory diseases29 and 4 to
6 weeks for gastrointestinal diseases30.
Dose of ciprooxacin in poultry
Different manufacturers recommend different
doses of the drug ranging from 1mg/ml to 1
mg/15ml in drinking water, on an average a young
chick consumes 250ml water per day which
means the intake of the drug is from 17mg to
250mg per day31,32,33.
Withdrawal period:
Withdrawal period is the time required after the
administration of a drug to an animal to assure
that drug residues in the marketable/saleable
product are below a determined maximum
residue limit (MRL). Withdrawal period is of
most concern during the administration of
drug to any edible product or food animal for
meat or eggs. According to European health
law and National Ofce of Animal Health, UK,
the statutory withdrawal period for Veterinary
Medicinal Products must not be less than 28 days
for meat from poultry and mammals34. However
ciprooxacin has a withdrawal period of 12-15
days in absolute conditions35.The recommended
duration of the therapy is 5-7 days and may be
prolonged upto 2 weeks depending upon the
severity and type of disease.
Administration of ciprooxacin to animals
(produced for commercial purpose) with a serious
impaired hepatic and/or renal function can alter
(increase) the protein binding of the drug leading
to an increased withdrawal time period of up to
23 days which is actually 12-15 days in normal
considerations.
CONCLUSIONS
From this study, it is clear that extensive use
of ciprooxacin in poultry is most likely to
develop complications/ resistance in pathogenic
organisms to human because of following
reasons;
Normal withdrawal period of the drug in animal
is 12-15 days from the time of last administered
dose. Administration of ciprooxacin to animals
(produced for commercial purpose) with seriously
impaired hepatic and/or renal function can alter
(increase) the protein binding of the drug leading
to an increased withdrawal time period (up to 23
days).
The usual age of the poultry chicken used for meat
purpose is 6-8 weeks (42-56 days), which means
that the therapy of ciprooxacin must be stopped
at the age of 19th day in order to complete the
withdrawal period of 23 days.
The usual age at which the respiratory diseases
affect the chicken is 21 days (at the age of 3
weeks) while the use of ciprooxacin must be
stopped before the age of 19th day, therefore its
use must be discouraged.
Furthermore its use may cause abnormal delivery
of drug to humans which may cause toxicity
in patients having probenecid therapy as co-
current use of ciprooxacin with probenecid (a
drug to treat gout and hyperuricemia) can lead
to 50% increase in concentration of ciprooxacin
in systemic circulation because of its reduced
renal clearance. It is observed that Ciprooxacin
impedes human cytochrome P450 1A2 (CYP1A2)
mediated metabolism.
Co-administration of ciprooxacin (even in a
very minute quantity) with other drugs which are
primarily metabolized by CYP1A2 particularly the
drugs which already have very narrow therapeutic
window like theophylline and tizanidine may
cause serious adverse events.
Similarly some other drugs of very common
and often long term use like,terbinane,

warfarin, clopidogrel,ondansetron, propafenone,
leunomide,propranolol, verapamil, naproxen,
zileutin, olanzapine, imipramine and mexiletine
may also show an increased plasma concentration
when used with ciprooxacin and have the
potential danger to cause clinically signicant
adverse events.
Overall, it is not possible to attain the complete
withdrawl period with the use of ciprooxacin in
poultry animals used for meat purpose within
the age of 6-8 weeks.While the unnecessary
exposure of ciprooxacin with a low dose for a
long period may also has its drawbacks regarding
the development of resistance in humans.

Present work describes the interactions of Ciprofloxacin Hydrochloride with different essential mineral salt like Magnesium Sulfate, Manganese Sulfate, Ferrous Sulfate, Zinc Sulfate and Potassium Chloride in an aqueous system at pH 7.4. This Magnesium Sulfate, Manganese Sulfate, Ferrous Sulfate, Zinc Sulfate and Potassium Chloride are essential trace element. From spectrophotometric study, it has been found that Ciprofloxacin Hydrochloride forms 1:1 complex with Magnesium Sulfate, Manganese Sulfate, Ferrous Sulfate, Zinc Sulfate and Potassium Chloride. Spectral studies helps to detect the initial complexation between drug and mineral salts. Job’s plot at 7.4 provides same type of information. An individual antimicrobial study (MIC) of Ciprofloxacin Hydrochloride in 1:1 mixture with Magnesium Sulfate, Manganese Sulfate, Ferrous Sulfate, Zinc Sulfate and Potassium Chloride at pH 7.4 was performed. These studies were carried out by observing the minimum inhibitory concentration (MIC) of the complexes and compared with the parent Cephradine against both Gram negative and Gram positive microorganisms in nutrient broth medium. Study confirms interactions of the Cephradine with Magnesium Sulfate, Manganese Sulfate, Ferrous Sulfate, Zinc Sulfate and Potassium Chloride and the interactions results into change the antimicrobial activity of Cephradine. Result shows that the antimicrobial activity increasing trends in presence of Magnesium Sulfate, Manganese Sulfate, Ferrous Sulfate and decreasing trends in presence of Zinc Sulfate and Potassium Chloride.DOI: http://dx.doi.org/10.3329/ijpls.v1i3.12977 International Journal of Pharmaceutical and Life Sciences Vol.1(3) 2012

There has been a growing rate of resistance among common urinary tract pathogens, such as Escherichia coli, to traditional antimicrobial therapies including the "gold standard" trimethoprim-sulfamethoxazole (TMP-SMX). Consequently, fluoroquinolone antimicrobial agents have taken on. an expanding management role for UTIs. In fact, the recent Infectious Diseases Society of America clinical management guidelines for UTI recommend fluoroquinolones as first-line therapy for uncomplicated UTI in areas where resistance is likely to be of concern. Fluoroquinolones have demonstrated high bacteriologic and clinical cure rates, as well as low rates of resistance, among most common uropathogens. There are currently 7 fluoroquinolones with indications for UTI in the United States. However, only 3 are commonly used: levofloxacin, ciprofloxacin, and, to a lesser extent, gatifloxacin. Many of the fluoroquinolone agents have once-daily dosing regimens, enhancing patient adherence. In addition, levofloxacin and gatifloxacin have same-dose bioequivalency between their intravenous and oral formulations, allowing for "switch" or step-down therapy from parenteral to oral formulations of the same agent at the same dose. Fluoroquinolones are indicated for the management of acute uncomplicated UTIs, as well as complicated and severe UTI and pyelonephritis, in adults. 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. Fluoroquinolone properties include a broad spectrum of coverage, low rates of resistance, and good safety profiles. (C) 2002 by Excerpta Medica, Inc.

In this paper, we found a new enhancement fluorescence system La-Tb-1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinolinecarboxylic acid (or ciprofloxacin, CPFX)-sodium dodecylbenzenesulfonate (SDBS), and the characteristic fluorescence of the La-Tb-CPFX-SDBS system was studied in detail. The effect of the experimental conditions on the fluorescence intensity was defined. By adding a suitable amount of La3+ to the Tb-CPFX-SDBS system, the fluorescence can be enhanced approximately three-fold. The fluorescence intensity is a linear function of europium up to a limit of 5.0×10−10 mol/l. The system was used for determination of terbium in rare earth samples with satisfactory results. The mechanism of fluorescence enhancement is also discussed.

Ciprofloxacin is a fluoroquinolone antibiotic that has a relatively low rate of occurence of adverse side effects. However, increasing evidences suggest that ciprofloxacin may cause unexpected severe liver damage. Especially, the risk of hepatotoxicity is significantly higher in elderly men receiving drug for a long time. In this article, 2 cases of unexpected severe hepatoxicity of ciprofloxacin are presented.

A method for the determination of trace amounts of ciprofloxacin has been developed, based on solid-phase spectrofluorimetry. The relative fluorescence intensity of ciprofloxacin fixed on Sephadex SP C-25 gel was measured directly after packing the gel beads in a 1-mm silica cell, using a solid-phase attachment. The wavelengths of excitation and emission were 272 and 448 nm, respectively. Using a sample volume of 1000 ml, the linear concentration range of application was 0.3-10.0 ng.ml(-1) of ciprofloxacin, with a R.S.D. of 1.2% (for a level of 4.0 ng.ml(-1)) and a detection limit of 0.1 ng.ml(-1). The method was applied to the determination of ciprofloxacin in human urine and serum samples. It was validated applying the standard addition methodology and using HPLC as a reference method. Recovery levels of the method reached 100% in all cases.

Little is known of clinical disease due to Mycobacterium chelonaechelonae. One hundred skin, soft tissue, or bone isolates of this rapidly growing mycobacterium were identified over 10 years. Clinical disease included disseminated cutaneous infection (53%); localized cellulitis, abscess, or osteomyelitis (35%); and catheter infections (12%). Underlying conditions with disseminated infection included organ transplantation, rheumatoid arthritis, and autoimmune disorders; 92% involved corticosteroid use. Trauma and medical procedures were risk factors for localized infections. Corticosteroids and chronic renal failure were risk factors for catheter infections. Overall, 62% of patients were receiving corticosteroids and 72% were immunosuppressed. MICs of six oral antimicrobials were obtained for 180 isolates by broth microdilution. Up to 20% of isolates were susceptible to doxycycline, ciprofloxacin, ofloxacin, and sulfamethoxazole. In contrast, 100% were susceptible to clarithromycin (MICs ⩽1 µg/mL). Disease due to M. chelonae usually occurs in the setting of corticosteroid therapy and is often disseminated; the organisms require high MICs of oral antimicrobials other than clarithromycin.

During the past decade, there has been a resurgence of interest in the development of oral macrolide and fluoroquinolone antimicrobial agents. Azithromycin and clarithromycin are two new oral macrolides whose pharmacokinetics (compared with those of erythromycin) are characterized by improved oral bioavailability, increased tissue penetration and persistence, and longer elimination half-lives. A limited number of interactions with other drugs have been reported for azithromycin and clarithromycin. The most common adverse reactions to the new macrolide agents include nausea, diarrhea, and abdominal pain. Norfloxacin, ciprofloxacin, ofloxacin, temafloxacin, and lomefloxacin are the oral fluoroquinolones that have been marketed in the United States thus far. In comparison to nalidixic acid, the newer fluoroquinolones have improved pharmacokinetic properties, including greater oral absorption, increased peak serum concentrations and areas under the curve, higher tissue concentrations, and longer elimination half-lives. Divalent or trivalent cations can alter the absorption of all fluoroquinolones. Some of the fluoroquinolones (norfloxacin, ciprofloxacin, and ofloxacin) can inhibit the cytochrome P-450 enzyme system and thereby cause increased serum concentrations of drugs like theophylline and caffeine. Adverse reactions to the fluoroquinolones primarily involve the gastrointestinal system, skin, and central nervous system.

An in vitro pharmacokinetic model was used to simulate the pharmacokinetics of trovafloxacin, ofloxacin, and ciprofloxacin in human serum and to compare their pharmacodynamics against eight Streptococcus pneumoniae strains. The MICs of ofloxacin and ciprofloxacin ranged from 1 to 2 micrograms/ml. Trovafloxacin was 8- to 32-fold more potent, with MICs of 0.06 to 0.12 microgram/ml. Logarithmic-phase cultures were exposed to peak concentrations of trovafloxacin, ofloxacin, or ciprofloxacin achieved in human serum after 200-, 400-, and 750-mg oral doses, respectively. Trovafloxacin was dosed at 0 and 24 h, and ofloxacin and ciprofloxacin were dosed at 0, 12, and 24 h. Human elimination pharmacokinetics were simulated, and viable bacterial counts were measured at 0, 2, 4, 6, 8, 12, 24, and 36 h. Trovafloxacin was rapidly and significantly bactericidal against all eight strains evaluated, with viable bacterial counts decreasing at least 5 logs to undetectable levels. Times to 99.9% killing were only 1 to 3 h. Although the rate of killing with ofloxacin was substantially slower than that with trovafloxacin, ofloxacin was also able to eradicate all eight strains from the model, despite a simulated area under the inhibitory curve/MIC ratio (AUC/MIC) of only 49. In contrast, ciprofloxacin eradicated only five strains (AUC/MIC = 44) from the model. Against the other three strains (AUC/MIC = 22), the antibacterial activity of ciprofloxacin was substantially diminished. These data corroborate clinical data and suggest that trovafloxacin has a pharmacodynamic advantage over ciprofloxacin and ofloxacin against S. pneumoniae in relation to its enhanced antipneumococcal activity.

To determine the intraocular penetration of topical drops of 2 antibiotics, ciprofloxacin 0.3% and ofloxacin 0.3%, into the aqueous humor and vitreous and to relate these levels to the miminum inhibitory concentration (MIC(90)) for organisms associated with ocular bacterial infections. Department of Ophthalmology, Ankara Hospital, and Department of Pharmacology, Faculty of Medicine, Hacettepe University, Ankara, Turkey. This prospective randomized clinical trial comprised 18 patients having cataract surgery, all with an intact corneal epithelium. The patients were randomly assigned to receive topical ciprofloxacin 0.3% (n = 10) or topical ofloxacin 0.3% (n = 8) 1 drop every 15 minutes 5 times and every 30 minutes 3 times before surgery. Aqueous and vitreous samples (if vitreous loss occurred during the cataract surgery) were collected 30 minutes after the administration of the last dose. Drug concentrations were determined by high-performance liquid chromatography (HPLC) fluorescence. All patients had detectable drug concentrations in the aqueous humor and vitreous measurable by HPLC. The mean aqueous humor concentration of ciprofloxacin was 1.13 microg/mL +/- 1.90 (SD) and the mean vitreous concentration, 0.23 +/- 0.06 microg/mL. Topical administration of ciprofloxacin yielded 4.9 times more drug concentration in the anterior chamber than in the vitreous. The mean aqueous concentration of ofloxacin was 2.06 +/- 1.06 microg/mL and the mean vitreous concentration, 0.46 +/- 0.10 microg/mL. Topical administration of ofloxacin yielded 4.7 times more drug concentration in the anterior chamber than in the vitreous. Aqueous humor concentrations of ofloxacin and ciprofloxacin were not statistically significantly different (P =.353). Intravitreal concentrations of ofloxacin were statistically significantly higher than those of ciprofloxacin (P =.001). Topical ofloxacin 0.3% penetrated better than topical ciprofloxacin 0.3% into the anterior chamber and vitreous in noninflamed eyes. Both drugs were above the MIC(90) for most ocular pathogens in the anterior chamber. The mean concentration in the vitreous of topically applied ofloxacin 0.3% was statistically significantly higher than that of ciprofloxacin 0.3%, but it was not sufficiently above the MIC(90) for most ocular pathogens in terms of empirical endopthalmitis therapy.
