Coliprid 250 mg, 500 mg, 750 mg TABLETS

COLIPRID TABLETS is indicated for the treatment of the following infections, when caused by susceptible organisms:

• Lower respiratory tract infections caused by: Enterobacter cloacae, Escherichia coli, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa.
• Urinary tract infections caused by: Citrobacter diversus, Citrobacter freundii, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Morganella morganii, Proteus mirabilis, Providencia rettgeri, Pseudomonas aeruginosa, Serratia marcescens, Staphylococcus epidermidis, Streptococcus faecalis.
• Skin and soft tissue infections caused by: Citrobacter freundii, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Morganella morganii, Proteus mirabilis, Proteus vulgaris, Providencia stuartii, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes.
• Gastro-intestinal infections: Infective diarrhoea caused by Campylobacter jejuni, Escherichia coli, Shigella flexneri and Shigella sonnei.
• Bone Infections: Osteomyelitis due to sensitive Gram-negative organisms.
• Gonorrhoea: (except that is due to N. gonorrhoeae) In the treatment of infections caused by Pseudomonas aeruginosa, an aminoglycoside must be administered concomitantly.

COLIPRID TABLETS should be swallowed whole with plenty of liquid and may be taken with or without meals. The dosage range is 250 - 750 mg twice daily. The duration of treatment depends upon the severity of the infection, clinical response and bacteriological cultures. For acute uncomplicated cystitis in women, the treatment period is 3 days. Generally, treatment should be continued for at least 3 days after the signs and symptoms of the infection have disappeared. For acute infections the usual treatment period is 5 - 10 days with COLIPRID TABLETS. For severe and complicated infections more prolonged therapy may be required. In streptococcal infections the treatment must last at least 10 days.

Infections of the lower respiratory tract:

• Mild to moderate: 250 - 500 mg twice daily.
• Severe or complicated: 750 mg twice daily.
• In cystic fibrosis patients: 750 mg twice daily. The low body mass of these patients should, however, be taken into consideration when determining dosage (7.5 to 15 mg/kg/day).

Infections of the urinary tract:

• Acute uncomplicated cystitis: 250 mg twice daily.
• Mild to moderate: 250 mg twice daily.
• Severe or complicated: 500 mg twice daily.

Infections of the skin:

• Mild to moderate: 500 mg twice daily.
• Severe or complicated: 750 mg twice daily.

Infectious diarrhoea: 500 mg twice daily.

Bone Infections:

• Mild to moderate: 500 mg twice daily.
• Severe or complicated: 750 mg twice daily. Treatment may be required for 4 - 6 weeks or longer.

Gonorrhoea: A single dose of 250 mg. Elderly patients should be treated with the lowest possible dose.

Impaired Renal or Liver Function: In patients with reduced renal function, the half-life of ciprofloxacin may be prolonged. The dosage needs to be adjusted as shown below. For patients with renal impaired and hepatic insufficiency, monitoring of medicine serum levels provides the most reliable basis for dose adjustment.

COLIPRID TABLETS is contra-indicated in patients with a history of hypersensitivity to ciprofloxacin, any other quinolones, or any of the inactive ingredients of COLIPRID TABLETS. Pregnancy and lactation: COLIPRID TABLETS is contra-indicated in children under the age of 18 years and in growing adolescents. Experimental evidence indicates lesions of the cartilage of weight-bearing joints in immature members of certain animal species.

COLIPRID TABLETS should be used in caution with patients with a history of convulsive disorders. Crystalluria related to the use of COLIPRID TABLETS has been observed. Patients receiving COLIPRID TABLETS should be well hydrated and excessive alkalinity of the urine should be avoided. Side-effects that may be potentially life-threatening are pancytopenia and bone marrow depression (see u201cSIDE - EFFECTSu201d).

Streptococcus pneumonia infections COLIPRID TABLETS should not be used for treatment of pneumococcal infections due to inadequate efficacy against Streptococcus pneumonia.

Severe infections and/or infections due to Gram-positive or anaerobic bacteria For the treatment of severe infections, staphylococcal infections and infections involving anaerobic bacteria, COLIPRID TABLETS should be used in combination with an appropriate antibacterial agent.

Genital tract infections Genital tract infections may be caused by fluoroquinolone-resistant Nesseria gonorrhoeae isolates. In genital tract infections thought to be due to N. Gonorrhoeae, COLIPRID TABLETS should not be used.

Cardiac disorders COLIPRID TABLETS is associated with cases of QT prolongation. In general, elderly patients may be more susceptible to COLIPRID TABLETS -associated effects on the QT interval. Precaution should be taken when using COLIPRID TABLETS with concomitant medicinal products that can result in prolongation of the QT interval (e.g. class IA or III antidysrhythmics) or in patients with risk factors for torsades de pointes (e.g. known QT prolongation, uncorrected hypokalaemia).

Hypersensitivity In some instances, hypersensitivity and allergic reactions already occurred after the first administration and the doctor should be informed immediately. Anaphylactic/anaphylactoid reactions can progress to life threatening shock, even after the first administration. In these cases COLIPRID TABLETS has to be discontinued, medical treatment (e.g. treatment for shock) is required.

Gastrointestinal system In the event of severe and persistent diarrhoea during or after treatment a doctor must be consulted, since this symptom can hide a serious intestinal disease (life threatening pseudomembranous colitis with possible fatal outcome), requiring immediate treatment. In such cases, COLIPRID TABLETS must be discontinued and appropriate therapy initiated. Medicines that inhibit peristalsis are contraindicated. There can be a temporary increase in transaminases, alkaline phosphatase or cholestatic jaundice, especially in patients with previous liver damage.

Musculoskeletal system At any sign of tendonitis (e.g. painful swelling) the administration of COLIPRID TABLETS should be discontinued, physical exercise should be avoided, and a medical practitioner consulted. Tendon rupture (predominantly Achilles tendon) has been reported predominantly in the elderly on prior systemic treatment with glucocorticoids and in patients with kidney or lung transplant. Close monitoring of these patients is necessary if they are prescribed COLIPRID TABLETS. The risk is still present weeks after completion of treatment.

Nervous system In patients with epilepsy and in patients who have suffered from previous CNS-disorders (e.g. lowered convulsion threshold, previous history of convulsion, reduced cerebral blood flow, altered brain structure or stroke), COLIPRID TABLETS should only be used where the benefits of treatment exceed the risks, since these patients are vulnerable because of possible central-nervous side effects. In some instances the CNS reactions already occurred after the first administration of COLIPRID TABLETS. In these cases COLIPRID TABLETS must be discontinued and the medical practitioner informed immediately. Depression or psychosis can progress to result in self-endangering behaviour.

Skin and appendages COLIPRID TABLETS has been shown to produce photosensitivity reactions. Patients taking COLIPRID TABLETS should avoid direct exposure to excessive sunlight or UV-light. Therapy should be discontinued if photosensitisation (i.e. sunburn-like skin reactions) occurs.

Cytochrome P450 Ciprofloxacin is known to be a moderate inhibitor of the CYP 450 1A2 enzymes. Care should be taken when other medicines which are metabolised via the same enzymatic pathway (e.g. theophylline, methylxanthines, caffeine, duloxetine, clozapine) are administered concomitantly with COLIPRID TABLETS. Increased plasma concentrations associated with medicine specific side effects may be observed due to inhibition of their metabolic clearance by COLIPRID TABLETS.

Patients receiving COLIPRID TABLETS should be well hydrated and excessive alkalinity of the urine should be avoided. Long-term or repeated administration of COLIPRID TABLETS can lead to superinfections with resistant bacteria or fungi.

Concurrent administration with methotrexate may increase the concentration of methotrexate to toxic levels. There is a high risk of tendonitis (see u201cSIDE - EFFECTSu201d). Concurrent administration of COLIPRID TABLETS with theophylline may lead to elevated plasma concentrations of theophylline and prolongation of its elimination half-life. This may result in increased risk of theophylline-related toxicity. If concomitant use cannot be avoided, plasma levels of theophylline should be monitored and dosage adjustments made as appropriate. COLIPRID TABLETS should be administered 1 - 2 hours before, or at least 4 hours after taking iron preparations, antacids containing magnesium, aluminium, calcium or sucralfate, as interference with absorption may occur. This restriction does not apply to antacids belonging to the class of H2-receptor blockers. Concomitant administration of the nonsteroidal anti-inflammatory medicines (NSAIDSs), with quinolones such as COLIPRID TABLETS may increase the risk of central nervous system stimulation and seizures. Monitoring of serum creatinine concentrations is advised in patients on concomitant ciclosporin therapy, as transient increases in serum creatinine concentrations have been observed. The simultaneous administration of COLIPRID TABLETS and warfarin may lead to warfarin toxicity; therefore the INR should be closely monitored. Concurrent administration of COLIPRID TABLETS and glibenclamide can potentiate the action of glibenclamide, leading to hypoglycaemia. Probenecid interferes with renal secretion of COLIPRID TABLETS. Co-administration of probenecid and COLIPRID TABLETS increases the COLIPRID TABLETS serum concentrations. Metoclopramide accelerates the absorption of COLIPRID TABLETS, resulting in a shorter time to reach maximum plasma concentrations. Concurrent administration of COLIPRID TABLETS with ropinirole may lead to elevated plasma concentrations of ropinirole. Monitoring for ropinirole-related side effects and appropriate dose adjustment of ropinirole is recommended during and shortly after co-administration with COLIPRID TABLETS. Concurrent administration of COLIPRID TABLETS with lidocaine (lignocaine) may lead to elevated plasma concentrations of lidocaine and increase in side effects related to lidocaine also occurs. Concurrent administration of COLIPRID TABLETS with clozapine may lead to elevated serum concentrations of clozapine and N-desmethylclozapine. Careful monitoring of clozapine associated adverse effects and appropriate adjustment of clozapine dosage during and shortly after co-administration with COLIPRID TABLETS is advised. Concurrent administration of COLIPRID TABLETS with sildenafil may lead to elevated serum concentrations of sildenafil. Therefore, sildenafil should be used with caution when co-administered with COLIPRID TABLETS.

Safety in pregnancy and lactation has not been established (See u201cCONTRA-INDICATIONSu201d). On the basis of animal studies, it has been reported that ciprofloxacin, as in COLIPRID TABLETS may cause damage to articular cartilage in the fetus. It has also been reported to cause teratogenic effects in animals. Therefore, COLIPRID TABLETS should not be given to pregnant women. Lactation: Ciprofloxacin is excreted in breastmilk. COLIPRID TABLETS should not be used during breastfeeding.

The ability to drive a motor vehicle or operate machinery may be impaired by COLIPRID TABLETS, particularly when used in combination with alcohol.

Side-effects Gastrointestinal disorders Frequent: Impaired taste and smell, nausea, diarrhoea, vomiting, dyspepsia, abdominal pain and flatulence.

In these cases COLIPRID TABLETS has to be discontinued and appropriate medical treatment instituted. Investigations The following side effects have been reported but the frequencies are unknown: Abnormal prothrombin level, increased amylase, Increased blood alkaline phosphatase, hyperglycaemia. Hepatobiliary Disorders Hepatic necrosis, very seldom progressing to hepatic failure, hepatic impairment, jaundice, hepatitis, increase in transaminases and bilirubin.

In the event of acute, excessive oral over-dosage, reversible renal toxicity has been reported. Apart from routine emergency measures, it is recommended to monitor renal function and to administer magnesium- or calcium-containing antacids which reduce the absorption of oral COLIPRID TABLETS. Only a small amount of ciprofloxacin (< 10 %) is removed from the body after haemodialysis or peritoneal dialysis. Treatment is symptomatic and supportive.
