How Ciplox Oz works

Ciprofloxacin acts on bacterial topoisomerase II (DNA gyrase) and topoisomerase IV. Ciprofloxacin's targeting of the alpha subunits of DNA gyrase prevents it from supercoiling the bacterial DNA which prevents DNA replication.

Use in Pregnancy and Lactation

Reproduction studies performed in rats and rabbits using parenteral and oral administration did not reveal any evidence of teratogenicity, impairment of fertility or impairment of pre or postnatal development. However, as with other quinolones, Ciprofloxacin has been shown to cause arthropathy in immature animals and therefore, its use during pregnancy is not recommended. Studies in rats have indicated that Ciprofloxacin is secreted in milk, administration to nursing mothers is thus not recommended.

Eye

Corneal Ulcers: The recommended dosage regimen for the treatment of corneal ulcers is 2 drops into the affected eye every 15 minutes for the first 6 hours and then 2 drops into the affected eye every 30 minutes for the remainder of the first day. On the second day, instill 2 drops in the affected eye hourly. On the third through the fourteenth day, place 2 drops in the affected eye every four hours. Treatment may be continued after 14 days if corneal re-epithelialization has not occurred.

Conjunctivitis: The recommended dosage regimen for the treatment of bacterial conjunctivitis is 1 or 2 drops instilled into the conjunctival sac(s) every 2 hours while awake for 2 days and one or 2 drops every 4 hours while awake for the next 5 days.

Ear

For all infections, 2-3 drops every 2-3 hours initially, reducing the frequency of the instillation with control of infection. Treatment should be continued at least 7 days.

Amoebiasis:

• Adults: 500 mg twice a day for 5 days.
• Children: 10-25 mg per kg body weight in two divided doses.

Amoebic dysentery:

• Adults: 1.5 gm once a day for 3 days.
• Children: 40 mg per kg body weight, once a day for 3 days.

Giardiasis:

• Adults: 1.5 gm once daily for 1-2 days.
• Children: 40 mg per kg body weight for 2 days.

Trichomoniasis: 1.5 gm once or 500 mg twice a day for 5 days. Sexual partner should also be treated at the same time.

Bacterial vaginosis: 3 tablets of 500 mg each as a single dose or one tablet of 500 mg once daily for 5-7 days.

Information for patients: Should be swallowed whole with an adequate amount of liquid, it may be taken with or without meals. The preferred time of dosing is two hours after a meal and patients should not take antacid within two hours of dosing.

Directions for use of granules for suspension

Whole contents of the packet should be taken into a small glass containing 2-3 teaspoonful of water. Other liquids or foods should not be used. The mixer should be stirred well and drink immediately. The glass should be refilled with water and drink.

Direction for reconstitution of suspension (60 ml)

Shake the bottle well to loosen the granules. Add 50 ml (with the help of supplied measuring cup) of boiled cool water to the dry granules in the bottle. Shake the bottle vigorously until all the granules is in suspension.

Side Effects

Ciprofloxacin is generally well tolerated. Frequent adverse reactions are- Gastrointestinal disturbance: e.g. nausea diarrhea, vomiting, dyspepsia, abdominal pain. Disturbance of the CNS: e.g. dizziness, headache, tiredness, confusion, convulsions. Hypersensitivity reactions: e.g. skin rashes, pruritus, and possible systemic reactions. Other possible side effects are - joint pain, light sensitivity, transient increase in liver enzyme (especially in patients with history of liver damage), serum bilirubin, urea or serum creatinine. Arthralgia and myalgia may also occur.

The most frequently reported drug related adverse reaction is local burning or discomfort. In corneal ulcer studies with frequent administration of the drug, white crystalline precipitates were seen in approximately 17% of patients. Other reactions occurring in less than 10% of patients included lid margin crusting, crystals/scales, foreign body sensation, itching, conjunctival hyperemia and a bad taste following instillation. Additional events occurring in less than 1% of patients included corneal staining, keratopathy/keratitis, allergic reactions, lid edema, tearing, photophobia, corneal infiltrates, nausea and decreased vision.

Side effects of Ornidazole have been mainly limited to the gastrointestinal tract (nausea, vomiting, epigastric pain) and central nervous system (dizziness, headache, lassitude). Unlike other nitroimidazoles, Ornidazole does not interact with alcohol, although this requires further study.

Leukopenia has been described occasionally during therapy. Adverse central nervous system (CNS) effects of Ornidazole have mainly included headache, dizziness, lassitude or somnolence, fatigue and weakness. Adverse CNS effects of Ornidazole may be less than that happens with metronidazole. Seizures have not been reported with Ornidazole in studies available to date.

Toxicity

Patients experiencing an overdose may present with nausea, vomiting, abdominal pain, crystalluria, nephrotoxicity, and oliguria. Ciprofloxacin overdose typically leads to acute renal failure. An overdose may progress over the next 6 days with rising serum creatinine and BUN, as well as anuria. Patients may require prednisone therapy, urgent hemodialysis, or supportive therapy. Depending on the degree of overdose, patients may recover normal kidney function or progress to chronic kidney failure.

The oral LD50 in rats is >2000mg/kg.

Ciprofloxacin for intratympanic injection or otic use has low systemic absorption and so it unlikely to be a risk in pregnancy or lactation. There is generally no harm to the fetus in animal studies, however high doses may lead to gastrointestinal disturbances in the mother which may increase the incidence of abortion. In human studies there was no increase in fetal malformations above background rates. The risk and benefit of ciprofloxacin should be weighed in pregnancy and breast feeding.

2/8 in vitro tests and 0/3 in vivo tests of mutagenicity of ciprofloxacin have yielded a positive result.

Oral doses of 200 and 300 times the maximum recommended clinical dose in rats and mice have shown no carcinogenicity or tumorigenicity.

Oral doses above the maximum recommended clinical dose have shown no effects on fertility in rats.

Precaution

Ciprofloxacin should be used with caution in patients with a history of convulsive disorders. Crystalluria related to the use of Ciprofloxacin has been observed only rarely. Patients receiving Ciprofloxacin should be well hydrated to avoid excessive alkalinity of the urine.

Beuflox Injection should only be administered by slow intravenous infusion over a period of 60 minutes. Local IV site reactions have been reported with the intravenous administration of Ciprofloxacin. These reactions are more frequent if infusion time is 30 minutes or less or if small vein of the hand are used.

In patient with ataxia, vertigo, and mental confusion, Ornidazole should be prescribed with caution. During prolonged treatment with Ornidazole, blood dyscrasia namely mild leukopenia have been reported rarely. In case leukopenia occurs, the decision to discontinue the therapy should depend upon the gravity of infection.

Interaction

Increased plasma levels of theophylline have been observed following concurrent administration with Ciprofloxacin. Ciprofloxacin suspension should not be administered within 4 hours of medications containing magnesium, aluminium, calcium or iron salts as interference with absorption may occur.

Like other imidazoles, Ornidazole has a mild potential to cause disulfiramlike reactions. Concomitant administration of oral anticoagulants may increase the risk of haemorrhage due to diminished hepatic metabolism. Ornidazole has been reported to decrease the clearance of 5-fluorouracil.

Volume of Distribution

Cirpofloxacin follws a 3 compartment distribution model with a central compartment volume of 0.161L/kg and a total volume of distribution of 2.00-3.04L/kg.

Elimination Route

A 250mg oral dose of ciprofloxacin reaches an average maximum concentration of 0.94mg/L in 0.81 hours with an average area under the curve of 1.013L/h*kg. The FDA reports an oral bioavailability of 70-80% while other studies report it to be approximately 60%. An early review of ciprofloxacin reported an oral bioavailability of 64-85% but recommends 70% for all practical uses.

Half Life

The average half life following a 250mg oral dose was 4.71 hours and 3.65 hours following a 100mg intravenous dose. Generally the half life is reported as 4 hours.

Clearance

The average renal clearance after a 250mg oral dose is 5.08mL/min*kg. Following a 100mg intravenous dose, the average total clearance is 9.62mL/min*kg, average renal clearance is 4.42mL/min*kg, and average non renal clearance is 5.21mL/min*kg.

Elimination Route

27% of an oral dose was recovered unmetabolized in urine compared to 46% of an intravenous dose. Collection of radiolabelled ciprofloxacin resulted in 45% recovery in urine and 62% recovery in feces.

Pregnancy & Breastfeeding use

Reproduction studies performed in rats and rabbits using parenteral and oral administration did not reveal any evidence of teratogenicity, impairment of fertility or impairment of pre or postnatal development. However, as with other quinolones, Ciprofloxacin has been shown to cause arthropathy in immature animals and therefore, its use during pregnancy is not recommended. Studies in rats have indicated that Ciprofloxacin is secreted in milk, administration to nursing mothers is thus not recommended.

Adequate clinical trials have not been conducted. Ornidazole should be prescribed only if the potential benefit justifies the potential risk to fetus/neonate.

Contraindication

Ciprofloxacin is contra-indicated in patients who have shown hypersensitivity to Ciprofloxacin or other quinolones.

Previous hypersensitivity to Ornidazole and to other nitroimidazoles. Ornidazole is contraindicated in central nervous system disorders, particularly in epilepsy or in peripheral neuropathy.

Acute Overdose

In case of acute overdose, the patient should be carefully observed and given supporative treatment, including monitoring of renal function. Adequate hydration must be maintained.

Renal Impairment Haemodialysis patients: Give a supplemental dose (50% of the usual dose) before dialysis.

Hepatic Impairment Severe: Double the interval between doses.

Storage Condition

Store in a cool dry place protected from light. Keep out of reach of children.

Store at room temperature and protect from light and moisture.
