How Ciprofloxacina D Dorf 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.

The short term effects of corticosteroids are decreased vasodilation and permeability of capillaries, as well as decreased leukocyte migration to sites of inflammation. Corticosteroids binding to the glucocorticoid receptor mediates changes in gene expression that lead to multiple downstream effects over hours to days.

Glucocorticoids inhibit neutrophil apoptosis and demargination; they inhibit phospholipase A2, which decreases the formation of arachidonic acid derivatives; they inhibit NF-Kappa B and other inflammatory transcription factors; they promote anti-inflammatory genes like interleukin-10.

Lower doses of corticosteroids provide an anti-inflammatory effect, while higher doses are immunosuppressive. High doses of glucocorticoids for an extended period bind to the mineralocorticoid receptor, raising sodium levels and decreasing potassium levels.

Dosage

Ciprofloxacina D Dorf dosage

Eye:

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

Bacterial Conjunctivitis:

The recommended dosage regimen for the treatment of bacterial conjunctivitis is one or two drops instilled into the conjunctival sac(s) every two hours while awake for two days and one or two drops every four hours while awake for the next five days.

Ear:

Four drops instilled into the affected ear twice daily for seven days. The suspension should be warmed by holding the bottle in the hand for one or two minutes to avoid dizziness, which may result from the instillation of a cold suspension. The patient should lie with the affected ear upward, and then the suspension should be instilled. This position should be maintained for 60 seconds. Repeat, if necessary, for the opposite ear.

Paediatric Use:

Ear: Safety and effectiveness of this suspension in pediatric (6 months of age and older) patients for ear application have been established.

Eye:

Safety and effectiveness of this suspension in pediatric patients for eye application have not been established.

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

Side Effects

The most frequently reported drug-related adverse reactions seen with Ciprofloxacin are transient ocular burning or discomfort. Other reported reactions include stinging, redness, itching, periocular/facial edema, foreign body sensation, photophobia, blurred vision, tearing, dryness and eye pain. Rare reports of dizziness have been received.

The reactions due to the steroid component are elevation of intraocular pressure (IOP) with possible development of glaucoma and infrequent optic nerve damage, posterior sub-capsular cataract formation and delayed wound healing.

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.

The oral LD₅₀ in female mice was 6.5g/kg and 794mg/kg via the intravenous route.

Overdoses are not expected with otic formulations. Chronic high doses of glucocorticoids can lead to the development of cataract, glaucoma, hypertension, water retention, hyperlipidemia, peptic ulcer, pancreatitis, myopathy, osteoporosis, mood changes, psychosis, dermal atrophy, allergy, acne, hypertrichosis, immune suppression, decreased resistance to infection, moon face, hyperglycemia, hypocalcemia, hypophosphatemia, metabolic acidosis, growth suppression, and secondary adrenal insufficiency. Overdose may be treated by adjusting the dose or stopping the corticosteroid as well as initiating symptomatic and supportive treatment.

Precaution

Shake the bottle well before use. Prolonged use of Ciprofloxacin may result in overgrowth of nonsusceptible organisms, including fungi. Prolonged use of steroids may result in glaucoma.The possibility of fungal infections of the cornea should be considered after long-term steroid dosing. Patients-wearing contact lenses must not use the drops during time the lenses are worn.

Interaction

Specific drug interaction studies have not been conducted with ophthalmic Ciprofloxacin and Dexamethasone. However, the systemic administration of some quinolones has been shown to elevate plasma concentrations of theophylline, interfere with the metabolism of caffeine, enhance the effects of the oral anticoagulant warfarin and its derivatives and have been associated with transient elevations in serum creatinine in patients receiving cyclosporin concomitantly.

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.

A 1.5mg oral dose of dexamethasone has a volume of distribution of 51.0L, while a 3mg intramuscular dose has a volume of distribution of 96.0L.

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.

Absorption via the intramuscular route is slower than via the intravenous route. A 3mg intramuscular dose reaches a C_max of 34.6±6.0ng/mL with a T_max of 2.0±1.2h and an AUC of 113±38ng*h/mL. A 1.5mg oral dose reaches a C_max of 13.9±6.8ng/mL with a T_max of 2.0±0.5h and an AUC of 331±50ng*h/mL. Oral dexamethasone is approximately 70-78% bioavailable in healthy subjects.

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.

The mean terminal half life of a 20mg oral tablet is 4 hours. A 1.5mg oral dose of dexamethasone has a half life of 6.6±4.3h, while a 3mg intramuscular dose has a half life of 4.2±1.2h.

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.

A 20mg oral tablet has a clearance of 15.7L/h. A 1.5mg oral dose of dexamethasone has a clearance of 15.6±4.9L/h while a 3.0mg intramuscular dose has a clearance of 9.9±1.4L/h.

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.

Corticosteroids are generally eliminated predominantly in the urine. However, dexamethasone is 15

Pregnancy & Breastfeeding use

Pregnancy

Ciprofloxacina D Dorf should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Lactation

It is not known whether topical administration of corticosteroids would result in sufficient systemic absorption to produce detectable quantities in human milk. It is also not known whether Ciprofloxacin is excreted in human milk following topical ophthalmic administration. Because many drugs are excreted in human milk, caution should be exercised when the combination is administered to a nursing woman.

Contraindication

Known hypersensitivity to any ingredient of the product. Herpes simplex and other viral conditions, mycosis, glaucoma, newborn babies, fungal diseases of ocular or auricular structures.
