04.0 CLINICAL INFORMATION
04.1 Therapeutic indications
Chinoplus is indicated for the treatment of infections caused by susceptible strains, in the following pathologies:
• acute uncomplicated infections of the lower urinary tract (simple cystitis);
• complicated lower urinary tract infections;
• exacerbation of chronic bronchitis;
• acute bacterial rhinosinusitis.
Acute bacterial sinusitis must be adequately diagnosed in accordance with national or local guidelines on the treatment of respiratory infections. For the treatment of bacterial rhinosinusitis, Chinoplus should only be used in patients in whom the duration of symptoms is less than 4 weeks and when the use of other commonly recommended antibacterials for the initial treatment of such infection is considered inappropriate, or in the case of which these were found to be ineffective.
In the treatment of patients with infectious diseases, local characteristics relating to antibiotic sensitivity must be taken into account.
04.2 Posology and method of administration
Dosage
The indicative dosage for adults is as follows:
• patients with uncomplicated acute lower urinary tract infections (simple cystitis): only one 600 mg tablet is sufficient.
• patients with complicated lower urinary tract infections: one 600 mg tablet once daily for up to 10 days of treatment.
• patients with exacerbation of bronchitis: one 600 mg tablet once a day for a maximum of 10 days of treatment.
• patients with acute bacterial rhinosinusitis: one 600 mg tablet once a day for a maximum of 10 days of treatment.
In the case of complicated lower urinary tract infections and acute exacerbation of chronic bronchitis, the duration of treatment depends on the severity of the disease and the clinical course of the patient and must in any case continue for at least 48-72 hours from the remission / disappearance of symptoms.
Pediatric population
Chinoplus should not be used in children and adolescents below 18 years of age due to safety concerns (see sections 4.3 and 5.3).
Method of administration
Chinoplus tablets should be swallowed whole with water and administered according to food intake (see Section 4.5).
04.3 Contraindications
- Hypersensitivity to prulifloxacin, to other quinolone antibacterials or to any of the excipients listed in section 6.1.
- Children before pubertal age or boys under the age of 18 with incomplete skeletal development.
- Patients with a history of tendon diseases related to the administration of quinolones.
- Pregnancy and lactation (see section 4.6).
04.4 Special warnings and appropriate precautions for use
As with other quinolones, Chinoplus should be used with caution in patients with CNS disorders that may predispose to seizures or lower the seizure threshold.
As with the administration of other drugs of the same therapeutic class, tendonitis occurs rarely. Most frequently it affects the Achilles tendon and can lead to its rupture. The risk of tendonitis and tendon ruptures is increased in elderly patients and in patients receiving corticosteroids. Patients should be advised, in the event of signs of tendon inflammation, myalgia, pain or joint inflammation, to discontinue treatment and to keep the affected limb or limbs at rest until the diagnosis of tendonitis. has been excluded.
Exposure to the sun or ultraviolet rays may cause phototoxicity in patients being treated with prulifloxacin, as well as with other quinolones. Excessive exposure to the sun or ultraviolet rays should be avoided during treatment with Chinoplus; in the event of phototoxicity, the treatment should be discontinued.
Patients with latent or known defects in glucose-6-phosphate dehydrogenase activity are prone to haemolytic reactions when treated with quinolone antibacterials and for this reason Chinoplus should be used with caution.
As reported for other quinolones, rhabdomyolysis phenomena may rarely occur, characterized by myalgia, asthenia, increased plasma CPK and myoglobin values, and rapid deterioration of renal function. In these cases, the patient should be carefully monitored and appropriate corrective measures taken, including possibly stopping treatment.
The use of quinolones is sometimes related to the appearance of crystalluria; patients treated with this class of products must maintain an adequate water balance in order to avoid urine concentration.
The tolerability and efficacy of Chinoplus in patients with hepatic insufficiency has not been evaluated.
Local and / or national guidelines on the appropriate use of antibacterials should be considered when prescribing antibiotic therapy.
The medicine contains lactose; therefore patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
Hepatic insufficiency
The tolerability and efficacy of Chinoplus in patients with hepatic insufficiency have not been evaluated. In the absence of specific studies, it is not possible to establish the posology for patients with hepatic insufficiency. Therefore, for such patients, the most reliable method for adjustment. of dosage is the monitoring of drug levels in plasma.
Kidney failure
Due to the lack of specific studies it is not possible to determine the posology in patients with renal insufficiency (patients with creatinine clearance plasma drug levels constitutes the most reliable method for dosage adjustment.
QT prolongation
Some of the other substances belonging to the fluoroquinolone class have been associated with cases of QT interval prolongation. Prulifloxacin has a very low potential for induction of QT interval prolongation.
Vision disorders
If vision becomes impaired or if any effects on the eyes occur, an ophthalmologist should be consulted immediately.
Disease associated with Clostridium difficile
If diarrhea occurs during or after prulifloxacin therapy (even several weeks after treatment), particularly if it is severe, persistent and / or bleeding, it could be a result of disease associated with Clostridium difficile (Clostridium difficile-associated disease, CDAD). The severity of CDAD can range from mild to life-threatening; the most severe form is pseudomembranous colitis (see section 4.8). Therefore, it is important to consider this diagnosis in patients who develop severe diarrhea during or after treatment with prulifloxacin. If CDAD is suspected or confirmed, ongoing treatment with antibacterial agents, including prulifloxacin, should be discontinued immediately and appropriate therapy initiated promptly. In this clinical condition, anti-peristaltic medicinal products are contraindicated. In addition, to reduce the risk of transmission, adequate infection control measures must be taken.
04.5 Interactions with other medicinal products and other forms of interaction
Concomitant treatment with cimetidine, antacids containing Al and Mg or preparations containing iron and calcium reduces the absorption of Chinoplus; consequently Chinoplus should be administered 2 hours before or at least 4 hours after taking these preparations.
The concomitant intake of prulifloxacin and milk causes a decrease in the area under the concentration / time curve (AUC) and reduces the urinary elimination of prulifloxacin, while the ingestion of food slows down and reduces peak levels.
The urinary excretion of prulifloxacin decreases when co-administered with probenecid. Concomitant administration of fenbufen with some quinolones may result in an increased risk of seizures; consequently the administration of Chinoplus and fenbufen should be carefully considered.
Quinolones can cause hypoglycemia in diabetic patients taking hypoglycemic drugs.
Concomitant administration of Chinoplus and theophylline may cause a slight decrease in theophylline clearance which is not expected to have any clinical relevance. However, as with other quinolones, monitoring of plasma theophylline levels is advisable in patients with metabolic disorders or who have risk factors.
Quinolones can enhance the effects of oral anticoagulants such as warfarin and its derivatives; if these products are co-administered with Chinoplus, close monitoring with prothrombin or other reliable coagulation tests is recommended.
Preclinical data have shown that nicardipine can potentiate the phototoxicity of prulifloxacin.
No clinically significant interactions have been observed during the clinical development of Chinoplus following concomitant administration with other medicinal products commonly used in the treatment of patients with the conditions listed in section 4.1.
04.6 Pregnancy and breastfeeding
Pregnancy
There are no clinical data on the use of prulifloxacin during established pregnancy.
Animal studies did not indicate teratogenicity. Other toxic effects on reproduction were only detected in the case of maternal toxicity (see section 5.3).
Feeding time
In rats, prulifloxacin was shown to cross the placental barrier and pass in large quantities into breast milk. As with other quinolones, prulifloxacin has been shown to cause arthropathies in young animals, and therefore its use during pregnancy and lactation is contraindicated.
04.7 Effects on ability to drive and use machines
Quinolones can cause dizziness and confusion, therefore, the patient should know how he responds to treatment before driving or operating machinery or engaging in activities that require alertness and coordination.
04.8 Undesirable effects
The undesirable effects listed below are attributable to clinical studies performed with Chinoplus, with the exception of adverse reactions with frequency not known. Most adverse events were mild or moderate in intensity.
The following MedDRA frequency values were used: Very common (≥1 / 10), Common (≥1 / 100,
The following adverse reactions have also been reported (frequency not known): anaphylactic / anaphylactoid reaction including angioedema, dyspnoea, Steven Johnson syndrome, hypoglycemia, hypoesthesia, paraesthesia, tremor, drug dermatitis, rhabdomyolysis, phototoxicity, tachycardia, pseudomembranous colitis.
Treatment with Chinoplus may be associated with asymptomatic crystalluria without changes in creatinine levels, alterations in liver function parameters and eosinophilia. In the cases observed, these changes were asymptomatic and transient.
During treatment with Chinoplus, the occurrence of adverse reactions and laboratory abnormalities not mentioned above, but reported for the other quinolones, cannot be excluded.
Pharmacovigilance data for prulifloxacin and post-marketing show sporadic reports of tendinopathy (see 4.4. Special warnings and precautions for use).
Reporting of suspected adverse reactions
Reporting of suspected adverse reactions occurring after authorization of the medicinal product is important as it allows continuous monitoring of the benefit / risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system. "address www.agenziafarmaco.gov.it/it/responsabili.
04.9 Overdose
Oral administration in mice, rats and dogs (male and female) of single doses up to 5000 mg / kg had no lethal effects.
No information is available on overdose in humans; Chinoplus has been administered up to a dose of 1200 mg / day for 12 days in healthy volunteers showing overall good tolerability.
In the case of acute overdose, the stomach should be emptied by inducing vomiting or gastric lavage, the patient should be carefully followed and treated with symptomatic therapy.
05.0 PHARMACOLOGICAL PROPERTIES
05.1 Pharmacodynamic properties
Pharmacotherapeutic group: fluoroquinolones.
ATC code: J01MA17.
Prulifloxacin is an antibacterial belonging to the class of fluoroquinolones with a broad spectrum of action and high efficacy. After oral administration, prulifloxacin is absorbed from the gastrointestinal tract and immediately converted to its active metabolite ulifloxacin (see section 5.2).
Mechanism of action. Chinoplus has been shown to be active in vitro, against a "wide range of Gram-positive and Gram-negative strains. Prulifloxacin exerts its antibacterial action by selectively inhibiting DNA-gyrase, a vital enzyme found in bacteria, which is involved in DNA duplication, transcription and repair.
Resistance mechanism. The onset of antibiotic resistance to prulifloxacin (as well as to other fluoroquinolones) is generally due to spontaneous mutations in the bacterial DNA gyrase domain. In vitro, cross-resistance with other fluoroquinolones has been observed.
Due to the particular mechanisms of onset of resistance to fluoroquinolones, there is no cross-resistance between prulifloxacin and antibiotics of different classes, therefore Chinoplus can be effective even in the presence of bacterial strains resistant to aminoglycosides, penicillins, cephalosporins and tetracyclines.
Intervals of inhibition. They have been defined on the basis of NCCLS antibacterial activity data and pharmacokinetic parameters of the product. The following inhibition ranges are suggested: Sensitive: MIC ≤ 1 mcg / ml, Intermediate: MIC> 1 to
Antibacterial spectrum. It should be considered that the prevalence of acquired resistance for selected species may vary geographically and with time, therefore local information on resistance is desirable, particularly when treating severe infections. If necessary, and if the local prevalence of resistance may make the drug usefulness questionable, it is advisable to seek expert advice.
The data reported in the table below indicate the antibacterial spectrum of prulifloxacin:
* Species showing a natural intermediate sensitivity
Other information. In in vitro studies, the antibacterial action of prulifloxacin was characterized by better bacterial penetration and a more prolonged post-antibiotic effect than the reference fluoroquinolones.
05.2 Pharmacokinetic properties
Prulifloxacin is the prodrug of the active metabolite, ulifloxacin.
Absorption - In humans, prulifloxacin is rapidly absorbed (Tmax = approximately 1h) and transformed to ulifloxacin; after a single administration of 600 mg the mean peak plasma of ulifloxacin is 1.6 mcg / ml and the AUC is 7.3 mcg * h / ml. At steady-state, which is reached within 2 days of the initiation of once-daily dosing, the Cmax and AUC are 2.0 mcg / ml and 7.6 mcg * h / ml, respectively. .
Food delays and slightly reduces the peak plasma concentration of ulifloxacin, but does not change the AUC.
Distribution - In humans, the lung / plasma ratio of the mean concentration of Chinoplus increases over time and, after 24 hours, the active metabolite ulifloxacin maintains mean tissue concentrations 5 times higher than those in plasma, confirming the results obtained in the animal. where the concentrations of ulifloxacin in the lung and kidney were higher than those in plasma (1.2 - 2.8 times and 3 - 8 times, respectively).
Similarly, human data on the tissue penetration of ulifloxacin into the paranasal sinuses showed, in terms of AUC, a tissue-to-plasma ratio of 3.0 in the ethmoid and 2.4 in the turbinates.
The protein binding in humans, assessed both in vitro that ex vivo, is approximately 50%, regardless of the drug concentration.
The low concentration of ulifloxacin found in the cerebrospinal fluid after i.v. in the dog and repeated administration p.o. in humans, it indicates that ulifloxacin hardly crosses the blood brain barrier.
Biotransformation - The metabolic profile of prulifloxacin in animals and humans is comparable. Animal studies have shown that the metabolism of prulifloxacin begins during intestinal absorption and is completed with its passage into the liver.
In addition to the transformation into ulifloxacin, other minor metabolites have been identified, such as the diol form and some derivatives such as glucuronide, oxo-derivative and ethylene-diamino derivatives, whose concentration and activity is negligible compared to the active principle.
No significant interactions with cytochrome P-450 isoenzymes were observed in in vitro studies, apart from a slight inhibition of CYP1A1 / 2 corresponding to a small decrease in theophylline clearance. Since methylxanthines, and in particular theophylline, constitute the main substrate for the CYP1A1 / 2 isoenzyme, the degree of interaction with other substrates of the isoenzyme (see warfarin) can be considered only lower.
Elimination - The half-life of the active metabolite, ulifloxacin, is approximately 10 hours after single and repeated steady-state administration in humans, while in animals (rats, dogs and monkeys) it varies between 2 and 12 hours.
Studies with the labeled product in humans have shown that elimination occurs mainly via the faecal route. After oral administration of 600 mg, the radioactivity recovered in urine and faeces amounts to approximately 95% in total. These results confirm what has been shown in previous studies carried out on animals (rats, dogs and monkeys).
The amount of ulifloxacin excreted in the urine is 16.7% of the administered dose on a molar basis and the renal clearance of ulifloxacin is approximately 170 ml / min.
Renal elimination of ulifloxacin occurs by glomerular filtration and by active secretion.
Elderly patients
The pharmacokinetic profile of prulifloxacin in the elderly has been shown to be similar to that in adults, with no change with age, and therefore no dosage adjustments are considered necessary in elderly patients.
In patients with mild or moderate renal insufficiency, after oral administration of Chinoplus 600 mg, the mean plasma peak of ulifloxacin reaches values between 1.30 and 1.62 mcg / ml. The AUC values vary between 13.71 and 23.33 mcg * h / ml and the half-life between 12.3 and 32.4 hours. The renal clearance of ulifloxacin decreases compared to healthy volunteers depending on the degree of insufficiency.
05.3 Preclinical safety data
Repeated toxicity. In repeated dose toxicity studies, joint cartilage, kidney, gastrointestinal tract and liver were the main target organs. With doses up to 3 times higher than the therapeutic ones, no toxic effects on articular cartilages were observed (young dogs); with doses up to 6, 10 and 12 times higher than the therapeutic ones, no toxic effects were observed in the liver (dogs) and kidney (dogs and rats).
The drug does not prolong the QT interval in vivo and does not demonstrate inhibitory effects on delayed rectification potassium current (HERG) in vitro.
Reproductive toxicity. Reproductive toxicity studies did not show teratogenicity. Effects on fertility or on embryonic and fetal development were observed only in cases of maternal toxicity.
Mutagenicity. Standard genotoxicity assays have shown positive effects in some in vitro tests performed with prulifloxacin in mammalian cell cultures, but were negative in vivo and in bacteria. These effects are believed to be associated with inhibition of topoisomerase II in the presence of high concentrations of prulifloxacin.
Carcinogenic potential. Prulifloxacin was not carcinogenic in a medium-term initiation-promotion model. Long-term carcinogenicity tests have not been performed.
Antigenicity. Prulifloxacin was found to have no antigenic effects.
Phototoxicity. Prulifloxacin induced phototoxic reactions, although in comparative studies in animals it showed a lower phototoxic activity than that of the other fluoroquinolones used (ofloxacin, enoxacin, pefloxacin, nalidixic acid and lomefloxacin). Many quinolones are also photomutagenic / photocarcinogenic, the possibility that prulifloxacin also has such effects cannot be ruled out.
Nephrotoxicity. After repeated oral administration of 3000 mg / kg / day in rats, a dosage much higher than the therapeutic dose in humans, prulifloxacin caused crystalluria by precipitation of ulifloxacin.
Cardiotoxicity. Studies in dogs have shown that prulifloxacin does not cause noticeable changes in the electrocardiogram. In particular, no changes in QTc were observed either after single intravenous administration in the anesthetized dog, or after oral administration for 6 months in the conscious dog, at all. the doses administered. In vitro studies confirmed the absence of inhibitory effects on delayed potassium rectifying currents (HERG).
Joint toxicity. Prulifloxacin, similarly to other fluoroquinolones, caused arthropathy only in young animals.
Ocular toxicity. Oral doses of 26.4 or 58.2 mg / kg / day of prulifloxacin once daily for 52 weeks in monkeys did not cause treatment-related adverse effects on ocular function or morphology.
Rhabdomyolytic effect. Doses up to 10 mg / kg / day of ulifloxacin administered intravenously once daily for 14 consecutive days did not induce rhabdomyolysis in rabbits.
