Itraconazole Solution


Pronunciation: IT-ra-KON-a-zole
Generic Name: Itraconazole
Brand Name: Sporanox

Itraconazole Solution has been shown to cause decreased heart function. Contact your doctor immediately if you experience symptoms of congestive heart failure such as swelling of the hands, ankles, feet, or abdomen; bloating; shortness of breath; fast or irregular heartbeat; severe or persistent nausea; or confusion.


Use of Itraconazole Solution along with certain other medicines may increase your risk of serious and sometimes fatal heart problems, including irregular heartbeat. Do not take Itraconazole Solution if you are also taking cisapride, pimozide, quinidine, dofetilide, or levacetylmethadol (levomethadyl).





Itraconazole Solution is used for:

Treating fungal infections. It may also be used for other conditions as determined by your doctor.


Itraconazole Solution is an azole antifungal. It kills sensitive fungi by interfering with the formation of the fungal cell membrane.


Do NOT use Itraconazole Solution if:


  • you are allergic to any ingredient in Itraconazole Solution

  • you are taking an aldosterone blocker (eg, eplerenone), alprazolam, astemizole, cisapride, conivaptan, dofetilide, an ergot alkaloid (eg, ergotamine), certain HMG-CoA reductase inhibitors (eg, lovastatin, simvastatin), levacetylmethadol (levomethadyl), oral midazolam, nevirapine, nisoldipine, pimozide, a quinazoline (eg, alfuzosin), quinidine, rifabutin, rifampin, terfenadine, triazolam, or certain 5-HT receptor agonists (eg, eletriptan)

Contact your doctor or health care provider right away if any of these apply to you.



Before using Itraconazole Solution:


Some medical conditions may interact with Itraconazole Solution. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:


  • if you are pregnant, planning to become pregnant, or are breast-feeding

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement

  • if you have allergies to medicines, foods, or other substances

  • if you are allergic to other azole antifungals (eg, ketoconazole)

  • if you have HIV infection, a weakened immune system, low white blood cell levels, cystic fibrosis, kidney or liver problems, abnormal liver function tests, lung or breathing problems (eg, chronic obstructive pulmonary disease [COPD]), low stomach acid (eg, hypochlorhydria), nerve problems, or problems with swelling or retaining fluid

  • if you have an irregular heartbeat or other heart problems (eg, congestive heart failure, coronary artery disease, heart valve problems)

  • if you have had serious liver problems caused by Itraconazole Solution or other medicines

Some MEDICINES MAY INTERACT with Itraconazole Solution. Tell your health care provider if you are taking any other medicines, especially any of the following:


  • Many prescription and nonprescription medicines (eg, used for infections, HIV, seizures, anxiety, sleep, heartburn, diabetes, high cholesterol, heart problems, high blood pressure, allergies, irregular heartbeat, pain, blood thinning, asthma, migraines, mood or mental problems, cancer, prostate problems, immune system suppression, erectile dysfunction, urinary problems, or birth control [eg, birth control pills]), multivitamin products, and herbal or dietary supplements may interact with Itraconazole Solution, increasing the risk of serious side effects

  • Nevirapine, rifabutin, or rifampin because they may decrease Itraconazole Solution's effectiveness

  • Astemizole, cisapride, dofetilide, levacetylmethadol (levomethadyl), nisoldipine, pimozide, quinidine, or terfenadine because the risk of severe heart effects may be increased

  • Alprazolam, midazolam, or triazolam because their actions and the risk of their side effects may be increased by Itraconazole Solution, resulting in increased risk of sedation and breathing difficulties

  • Aldosterone blockers (eg, eplerenone), calcium channel blockers (eg, verapamil), conivaptan, ergot alkaloids (eg, ergotamine), certain HMG-CoA reductase inhibitors (eg, lovastatin, simvastatin), 5-HT receptor agonists (eg, eletriptan), or quinazolines (eg, alfuzosin) because the risk of their side effects may be increased by Itraconazole Solution

This may not be a complete list of all interactions that may occur. Ask your health care provider if Itraconazole Solution may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.


How to use Itraconazole Solution:


Use Itraconazole Solution as directed by your doctor. Check the label on the medicine for exact dosing instructions.


  • Take Itraconazole Solution on an empty stomach at least 1 hour before or 2 hours after eating.

  • Use a measuring device marked for medicine dosing. Ask your pharmacist for help if you are unsure of how to measure your dose.

  • If you are using Itraconazole Solution to treat a mouth or throat infection, swish Itraconazole Solution in your mouth for several seconds before swallowing, unless directed otherwise by your doctor.

  • Do not take antacids within 1 hour before or 2 hours after taking Itraconazole Solution.

  • Take Itraconazole Solution at least 2 hours before proton pump inhibitors (eg, omeprazole).

  • To clear up your infection completely, take Itraconazole Solution for the full course of treatment. Keep taking it even if you feel better in a few days. Do not miss any doses.

  • Itraconazole Solution works best if it is taken at the same time each day.

  • If you miss a dose of Itraconazole Solution, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Itraconazole Solution.



Important safety information:


  • Itraconazole Solution may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Itraconazole Solution with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.

  • Rarely, Itraconazole Solution has been associated with serious, sometimes fatal liver damage. Contact your doctor right away if you notice dark urine, pale stools, a swollen or tender stomach, or yellowing of the skin or eyes.

  • Itraconazole Solution only works against fungi; it does not treat viral infections (eg, the common cold).

  • Be sure to use Itraconazole Solution for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The fungus could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.

  • Do not switch between the capsule and oral solution forms of Itraconazole Solution without checking with your doctor. Effectiveness and side effects of these forms of Itraconazole Solution may be different even at the same dose.

  • Diabetes patients - Itraconazole Solution may increase the risk of low blood sugar from your diabetes medicine. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.

  • Hormonal birth control (eg, birth control pills) may not work as well while you are using Itraconazole Solution. To prevent pregnancy, use an extra form of birth control (eg, condoms).

  • If you are using Itraconazole Solution to treat a certain type of fungal infection (onychomycosis), you should use an effective form of birth control while you are taking Itraconazole Solution and for 2 months after you have stopped treatment. Talk with your doctor about effective forms of birth control.

  • Tell your doctor or dentist that you take Itraconazole Solution before you receive any medical or dental care, emergency care, or surgery.

  • Lab tests, including liver function, may be performed while you use Itraconazole Solution. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.

  • Use Itraconazole Solution with caution in the ELDERLY; they may be more sensitive to its effects, especially loss of hearing.

  • Itraconazole Solution should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.

  • PREGNANCY and BREAST-FEEDING: It is not known if Itraconazole Solution can cause harm to the fetus. If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Itraconazole Solution while you are pregnant. Itraconazole Solution is found in breast milk. If you are or will be breast-feeding while you use Itraconazole Solution, check with your doctor. Discuss any possible risks to your baby.

Dialysis: infections associated with haemo - and peritoneal dialysis and with continuous ambulatory peritoneal dialysis (CAPD)



In meningitis it is recommended that the results of a sensitivity test are known before treatment with ceftazidime as a single agent. It may be used for infections caused by organisms resistant to other antibiotics including aminoglycosides and many cephalosporins. When appropriate, however, it may be used in combination with an aminoglycoside or other beta-lactam antibiotic for example, in the presence of severe neutropenia, or with an antibiotic active against anaerobes when the presence of bacteroides fragilis is suspected. In addition, ceftazidime is indicated in the perioperative prophylaxis of transurethral prostatectomy.



In vitro the activities of ceftazidime and aminoglycoside antibiotics in combination have been shown to be at least additive; there is evidence of synergy in some strains tested. This property may be important in the treatment of febrile neutropenic patients.



Consideration should be given to official guidance on the appropriate use of antibacterial agents.



4.2 Posology And Method Of Administration



Ceftazidime is to be used by the parenteral route, the dosage depending upon the severity, sensitivity and type of infection and the age, weight and renal function of the patient.



Adults: The adult dosage range for ceftazidime is 1 to 6g per day 8 or 12 hourly (im or iv). In the majority of infections, 1g 8-hourly or 2g 12-hourly should be given. In urinary tract infections and in many less serious infections, 500mg or 1g 12-hourly is usually adequate. In very severe infections, especially immunocompromised patients, including those with neutropenia, 2g 8 or 12-hourly or 3g 12-hourly should be administered.



When used as a prophylactic agent in prostatic surgery 1g (from the 1g vial) should be given at the induction of anaesthesia. A second dose should be considered at the time of catheter removal.



Elderly: In view of the reduced clearance of ceftazidime in acutely ill elderly patients, the daily dosage should not normally exceed 3g, especially in those over 80 years of age.



Cystic fibrosis: In fibrocystic adults with normal renal function who have pseudomonal lung infections, high doses of 100 to 150mg/kg/day as three divided doses should be used. In adults with normal renal function 9g/day has been used.



Infants and children: The usual dosage range for children aged over two months is 30 to 100mg/kg/day, given as two or three divided doses.



Doses up to 150mg/kg/day (maximum 6g daily) in three divided doses may be given to infected immunocompromised or fibrocystic children or children with meningitis.



Neonates and children up to 2 months of age: Whilst clinical experience is limited, a dose of 25 to 60mg/kg/day given as two divided doses has proved to be effective. In the neonate the serum half-life of ceftazidime can be three to four times that in adults.



Dosage in impaired renal function: Ceftazidime is excreted by the kidneys almost exclusively by glomerular filtration. Therefore, in patients with impaired renal function it is recommended that the dosage of ceftazidime should be reduced to compensate for its slower excretion, except in mild impairment, i.e. glomerular filtration rate (GFR) greater than 50ml/min. In patients with suspected renal insufficiency, an initial loading dose of 1g of ceftazidime may be given. An estimate of GFR should be made to determine the appropriate maintenance dose.



Renal impairment: For patients in renal failure on continuous arteriovenous haemodialysis or high-flux haemofiltration in intensive therapy units, it is recommended that the dosage should be 1g daily in divided doses. For low-flux haemofiltration it is recommended that the dosage should be that suggested under impaired renal function.



Recommended maintenance doses are shown below:

* These values are guidelines and may not accurately predict renal function in all patients especially in the elderly in whom the serum creatinine concentration may overestimate renal function.



In patients with severe infections, especially in neutropenics, who would normally receive 6g of ceftazidime daily were it not for renal insufficiency, the unit dose given in the table above may be increased by 50% or the dosing frequency increased appropriately. In such patients it is recommended that ceftazidime serum levels should be monitored and trough levels should not exceed 40mg/litre.



When only serum creatinine is available, the following formula (Cockcroft's equation) may be used to estimate creatinine clearance. The serum creatinine should represent a steady state of renal function:



Males:







Creatinine clearance =

Weight (kg) x (140 - age in years)

(ml/min)

72 x serum creatinine (mg/dl)


Females:



0.85 x above value.



To convert serum creatinine in µmol/litre into mg/dl divide by 88.4.



In children the creatinine clearance should be adjusted for body surface area or lean body mass and the dosing frequency reduced in cases of renal insufficiency as for adults.



The serum half-life of ceftazidime during haemodialysis ranges from 3 to 5 hours. The appropriate maintenance dose of ceftazidime should be repeated following each haemodialysis period.



Dosage in peritoneal dialysis: Ceftazidime may also be used in peritoneal dialysis and continuous ambulatory peritoneal dialysis (CAPD). As well as using ceftazidime intravenously, it can be incorporated into the dialysis fluid (usually 125 to 250mg for 2L of dialysis fluid).



Administration: Ceftazidime may be given intravenously or by deep intramuscular injection into a large muscle mass such as the upper outer quadrant of the gluteus maximus or lateral part of the thigh.



4.3 Contraindications



Ceftazidime is contraindicated in patients with known hypersensitivity to cephalosporin antibiotics.



4.4 Special Warnings And Precautions For Use



Hypersensitivity reactions:



As with other beta-lactam antibiotics, before therapy with ceftazidime is instituted, careful inquiry should be made for a history of hypersensitivity reactions to ceftazidime, cephalosporins, penicillins or other drugs. Special care is indicated in patients who have experienced an allergic reaction to penicillins or beta-lactams. Ceftazidime should be given only with special caution to patients with type I or immediate hypersensitivity reactions to penicillin. If an allergic reaction to ceftazidime occurs, discontinue the drug. Serious hypersensitivity reactions may require adrenaline (epinephrine), hydrocortisone, antihistamine or other emergency measures.



Renal function:



Cephalosporin antibiotics at high dosage should be given with caution to patients receiving concurrent treatment with nephrotoxic drugs, e.g. aminoglycoside antibiotics, or potent diuretics such as furosemide, as these combinations are suspected of affecting renal function adversely. Clinical experience with ceftazidime has shown that this is not likely to be a problem at the recommended dose levels. There is no evidence that ceftazidime adversely affects renal function at normal therapeutic doses: however, as for all antibiotics eliminated via the kidneys, it is necessary to reduce the dosage according to the degree of reduction in renal function to avoid the clinical consequences of elevated antibiotic levels, e.g. neurological sequelae, which have occasionally been reported when the dose has not been reduced appropriately (see 4.2 Dosage in Impaired Renal Function and 4.8 Undesirable Effects).



Overgrowth of non-susceptible organisms:



As with other broad spectrum antibiotics, prolonged use of ceftazidime may result in the overgrowth of non-susceptible organisms (e.g. Candida, Enterococci and Serratia spp) which may require interruption of treatment or adoption of appropriate measures. Repeated evaluation of the patient's condition is essential.



4.5 Interaction With Other Medicinal Products And Other Forms Of Interaction



Ceftazidime does not interfere with enzyme-based tests for glycosuria. Slight interference with copper reduction methods (Benedict's, Fehling's, Clinitest) may be observed. Ceftazidime does not interfere in the alkaline picrate assay for creatinine. The development of a positive Coombs' test associated with the use of ceftazidime in about 5% of patients may interfere with the cross-matching of blood.



Chloramphenicol is antagonistic in vitro with ceftazidime and other cephalosporins. The clinical relevance of this finding is unknown, but if concurrent administration of ceftazidime with chloramphenicol is proposed, the possibility of antagonism should be considered.



In common with other antibiotics, ceftazidime may affect the gut flora, leading to lower oestrogen reabsorption and reduced efficacy of combined oral contraceptives. Therefore, alternative non-hormonal methods of contraception are recommended.



4.6 Pregnancy And Lactation



There is no experimental evidence of embryopathic or teratogenic effects attributable to ceftazidime but, as with all drugs, it should be administered with caution during the early months of pregnancy and in early infancy. Use in pregnancy requires that the anticipated benefit be weighed against the possible risks.



Ceftazidime is excreted in human milk in low concentrations and consequently caution should be exercised when ceftazidime is administered to a nursing mother.



4.7 Effects On Ability To Drive And Use Machines



None reported.



4.8 Undesirable Effects



Data from large clinical trials (internal and published) were used to determine the frequency of very common to uncommon undesirable effects. The frequencies assigned to all other undesirable effects were mainly determined using post-marketing data and refer to a reporting rate rather than a true frequency.

Serum levels of ceftazidime can be reduced by dialysis.



5. Pharmacological Properties



5.1 Pharmacodynamic Properties



ATC classification



Pharmacotherapeutic group: cephalosporins ATC code: J01DD02



Mode of action



Ceftazidime inhibits bacterial cell wall synthesis following attachment to penicillin binding proteins (PBPs). This results in the interruption of cell wall (peptidoglycan) biosynthesis, which leads to bacterial cell lysis and death.



Mechanism of Resistance



Ceftazidime is effectively stable to hydrolysis by most classes of beta-lactamases, including penicillinases and cephalosporinases but not extended spectrum beta-lactamases.



Bacterial resistance to ceftazidime may be due to one or more of the following mechanisms:



- hydrolysis by beta-lactamases. Ceftazidime may be efficiently hydrolysed by certain of the extended-spectrum beta-lactamases (ESBLs) including the SHV plasmid mediated ESBLs and by the chromosomally-encoded (AmpC) enzyme that may be induced or stably derepressed in certain aerobic gram-negative bacterial species



- reduced affinity of penicillin-binding proteins for ceftazidime



- outer membrane impermeability, which restricts access of ceftazidime to penicillin binding proteins in gram-negative organisms



- drug efflux pumps.



Breakpoints



Minimum inhibitory concentration (MIC) breakpoints established by the European Committee on Antimicrobial Susceptibility Testing (EUCAST) are as follows:



- Enterobacteriaceae: S =< 1 mg/l and R > 8 mg/l



- Pseudomonas aeruginosa: S =< 8 mg/l and R > 8 mg/l



Microbiological Susceptibility



The prevalence of acquired resistance may vary geographically and with time for selected species and local information on resistance is desirable, particularly when treating severe infections. As necessary, expert advice should be sought when the local prevalence of resistance is such that the utility of ceftazidime in at least some types of infections is questionable.

5.2 Pharmacokinetic Properties



Ceftazidime administered by the parenteral route reaches high and prolonged serum levels in man. After intramuscular administration of 500mg and 1g serum mean peak levels of 18 and 37mg/litre respectively are rapidly achieved. Five minutes after an intravenous bolus injection of 500mg, 1g or 2g, serum mean levels are respectively 46, 87 and 170mg/litre.



Therapeutically effective concentrations are still found in the serum 8 to 12 hours after both intravenous and intramuscular administration. The serum half-life is about 1.8 hours in normal volunteers and about 2.2 hours in patients with apparently normal renal function. The serum protein binding of ceftazidime is low at about 10%.



Ceftazidime is not metabolised in the body and is excreted unchanged in the active form into the urine by glomerular filtration. Approximately 80 to 90% of the dose is recovered in the urine within 24 hours. Less than 1% is excreted via the bile, significantly limiting the amount entering the bowel.



Concentrations of ceftazidime in excess of the minimum inhibitory levels for common pathogens can be achieved in tissues such as bone, heart, bile, sputum, aqueous humour, synovial and pleural and peritoneal fluids. Transplacental transfer of the antibiotic readily occurs. Ceftazidime penetrates the intact blood brain barrier poorly and low levels are achieved in the csf in the absence of inflammation. Therapeutic levels of 4 to 20mg/litre or more are achieved in the csf when the meninges are inflamed.



5.3 Preclinical Safety Data



No additional data of relevance.



6. Pharmaceutical Particulars

*Note: Addition should be in two stages.



‡Note: Use Sodium Chloride Injection 0.9%, Dextrose Injection 5% or other approved diluent (see pharmaceutical precautions) as Water for Injections produces hypotonic solutions at this concentration.



All sizes of vials as supplied are under reduced pressure. As the product dissolves, carbon dioxide is released and a positive pressure develops. For ease of use, it is recommended that the following techniques of reconstitution are adopted.



250mg i.m./i.v., 500mg i.m./i.v., 1g i.m./i.v., and 2g and 3g i.v. bolus vials:



1. Insert the syringe needle through the vial closure and inject the recommended volume of diluent. The vacuum may assist entry of the diluent. Remove the syringe needle.



2. Shake to dissolve: carbon dioxide is released and a clear solution will be obtained in about 1 to 2 minutes.



3. Invert the vial. With the syringe plunger fully depressed, insert the needle through the vial closure and withdraw the total volume of solution into the syringe (the pressure in the vial may aid withdrawal). Ensure that the needle remains within the solution and does not enter the head space. The withdrawn solution may contain small bubbles of carbon dioxide; they may be disregarded.



2g and 3g i.v. infusion vials:



This vial may be constituted for short intravenous infusion (e.g. up to 30 minutes) as follows (mini-bag or burette-type set):



Prepare using a total of 50ml (for 2g vials) and 75ml (for 3g vials) of compatible diluent, added in TWO stages as below:-



1. Insert the syringe needle through the vial closure and inject 10ml of diluent for 2g vial and 15ml for 3g vial. The vacuum may assist entry of the diluent. Remove the syringe needle.



2. Shake to dissolve: carbon dioxide is released and a clear solution obtained in about 1 to 2 minutes.



3. Do not insert a gas relief needle until the product has dissolved. Insert a gas relief needle through the vial closure to relieve the internal pressure.



4. Transfer the reconstituted solution to final delivery vehicle (e.g. mini-bag or burette-type set) making up a total volume of a least 50ml (75ml for the 3g vial), and administer by intravenous infusion over 15-30 minutes.



NOTE: To preserve product sterility, it is important that a gas relief needle is not inserted through the vial closure before the product has dissolved.



Fortum Monovial:



The contents of the Monovial are added to small volume infusion bags containing 0.9% Sodium Chloride Injection or 5% Dextrose Injection, or another compatible fluid.



The 2g presentation must be constituted in not less than 100mL infusion bag.



1) Peel off the removable top part of the label and remove the cap.



2) Insert the needle of the Monovial into the additive port of the infusion bag.



3) To activate, push the plastic needle holder of the Monovial down onto the vial shoulder until a "click" is heard.



4) Holding it upright, fill the vial to approximately two-thirds capacity by squeezing the bag several times.



5) Shake the vial to reconstitute the Fortum.



6) On constitution, the Fortum will effervesce slightly.



7) With the vial uppermost, transfer the reconstituted Fortum into the infusion bag by squeezing and releasing the bag.



8) Repeat the steps 4 to 7 to rinse the inside of the vial. Dispose of the empty Monovial safely. Check that the powder is completely dissolved and that the bag has no leaks.



Fortum Monovial is for i.v. infusion only.



These solutions may be given directly into the vein or introduced into the tubing of a giving set if the patient is receiving parenteral fluids. Ceftazidime is compatible with the most commonly used intravenous fluids.



Vials of Fortum for Injection and Fortum Monovials as supplied are under reduced pressure; a positive pressure is produced on constitution due to the release of carbon dioxide.



Vials of Fortum for Injection should be stored at a temperature below 25°C.



Vials of Fortum for Injection do not contain any preservatives and should be used as single-dose preparations.



In keeping with good pharmaceutical practice, it is preferable to use freshly constituted solutions of Fortum for Injection. If this is not practicable, satisfactory potency is retained for 24 hours in the refrigerator (2 - 8°C) when prepared in Water for Injection BP or any of the injections listed below.
