How Mahaflox Kt works

Ketorolac inhibits key pathways in prostaglandin synthesis which is crucial to it's mechanism of action. Although ketorolac is non-selective and inhibits both COX-1 and COX-2 enzymes, it's clinical efficacy is derived from it's COX-2 inhibition. The COX-2 enzyme is inducible and is responsible for converting arachidonic acid to prostaglandins that mediate inflammation and pain. By blocking this pathway, ketorolac achieves analgesia and reduces inflammation. Ketorolac is administered as a racemic mixture; however, the "S" enantiomer is largely responsible for it's pharmacological activity.

The bactericidal action of moxifloxacin results from inhibition of the enzymes topoisomerase II (DNA gyrase) and topoisomerase IV. DNA gyrase is an essential enzyme that is involved in the replication, transcription and repair of bacterial DNA. Topoisomerase IV is an enzyme known to play a key role in the partitioning of the chromosomal DNA during bacterial cell division.

Dosage

Mahaflox Kt dosage

Ketorolac Tablet-

Ketorolac Tablet isrecommended for short-term use only (up to 7 days) and are not recommended for chronic use. 10 mg every 4 to 6 hours as required. Doses exceeding 40 mg/day are not recommended. For patients receiving parenteral Ketorolac tromethamine, and who are converted to Ketorolac tromethamine oral tablets, the total combined daily dose should not exceed 90 mg (60 mg for the elderly, renally impaired patients and patients less than 50 kg) and the oral component should not exceed 40 mg on the day the change of formulation is made. Patients should be converted to oral treatment as soon as possible.

Ketorolac injection-

Ketorolac injection may be used as a single or multiple doses, on a regular or when necessary schedule for the management of moderately severe, acute pain that requires analgesia at the opioid level, usually in a postoperative setting. When administering Ketorolac injection, the IV bolus must be given over no less than 15 seconds. The IM administration should be given slowly and deeply into the muscle. The analgesic effect begins within 30 minutes with maximum effect in 1 to 2 hours after dosing IV or IM. Duration of analgesic effect is usually 4 to 6 hours. Single-Dose Treatment: The following regimen should be limited to single administration use only.

IM Dosing (Adult):

• Patients <65 years of age: One dose of 60 mg.
• Patients >65 years of age, renally impaired and/or less than 50 kg of body weight: One dose of 30 mg.

IV Dosing (Adult):

• Patients <65 years of age: One dose of 30 mg.
• Patients >65 years of age, renally impaired and/or less than 50 kg of body weight: One dose of 15 mg.

IV or IM Dosing (2 to 16 years of age):

• IM Dosing: One dose of 1 mg/kg up to a maximum of 30 mg.
• IV Dosing: One dose of 0.5 mg/kg up to a maximum of 15 mg.

Multiple-Dose Treatment (IV or IM):

• Patients <65 years of age: The recommended dose is 30 mg Ketorolac injection every 6 hours. The maximum daily dose should not exceed 120 mg. Patients >65 years of age, renally impaired patients and patients less than 50 kg: The recommended dose is 15 mg Ketorolac injection every 6 hours. The maximum daily dose for these populations should not exceed 60 mg. For breakthrough pain, do not increase the dose or the frequency of Ketorolac Tromethamine.
• Conversion from Parenteral to Oral Therapy: Ketorolac tablets may be used either as monotherapy or as follow-on therapy to parenteral Ketorolac. When Ketorolac tablets are used as a follow-on therapy to parenteral Ketorolac, the total combined daily dose of ketorolac (oral + parenteral) should not exceed 120 mg in younger adult patients or 60 mg in elderly patients on the day the change of formulation is made. On subsequent days, oral dosing should not exceed the recommended daily maximum of 40 mg. Ketorolac IM should be replaced by Ketorolac tablet as soon as feasible. The total duration of combined parenteral andoral treatment should not exceed 5 days.

Ketorolac Nasal spray-

• Adults weighing 50 kg or more: 31.5 mg or 2 spray in each nostril every 6 to 8 hours. Your doctor may adjust your dose if needed. However, the dose is not more than 126 mg (a total of 8 sprays) per day.
• Older adults and adults weighing less than 50 kg:15.75 mg or 1 spray in only one nostril every 6 to 8 hours. However, the dose is usually not more than 63 mg (a total of 4 sprays) per day.
• Children: Use and dose must be determined by your doctor.

The dose of Moxifloxacin is 400 mg once every 24 hours. The duration of therapy depends on the type of infection as described bellow-

• In Acute Bacterial Sinusitis: Moxifloxacin 400 mg is given once daily for 10 days.
• In Acute Bacterial Exacerbation of Chronic Bronchitis: Moxifloxacin 400 mg is given once daily for 5 days.
• In Community Acquired Pneumonia: Moxifloxacin 400 mg is given once daily for 7-14 days.
• In Uncomplicated Skin & Skin Structure infections: Moxifloxacin 400 mg is given once daily for 7 days.
• In Complicated Skin & Skin Structure infections: Moxifloxacin 400 mg is given once daily for 7-21 days.
• In Complicated Intra-Abdominal infections: Moxifloxacin 400 mg is given once daily for 5-14 days.

Moxifloxacin 400 mg IV infusion can be administered intravenously for the entire treatment duration. Alternatively, therapy may be initial intravenous administration, followed by oral administration when clinically indicated. The recommended duration of treatment for the indication being treated should not be exceeded. The solution for infusion should be infused intravenously over 60 minutes.

Side Effects

Commonly occurring side-effects are nausea, vomiting, gastro intestinal bleeding,melaena, peptic ulcer, pancreatitis, anxiety, drowsiness, dizziness, headache, hallucinations,excessive thirst, inability to concentrate, insomnia, malaise, fatigue, pruritus, urticaria, skin photosensitivity, Lyell's syndrome, Stevens-Johnson syndrome, flushing, bradycardia, hypertension, palpitations, chest pain, infertility in female, dyspnoea, asthma, pulmonary oedema, fever, injection site pain.

The following one or more side effects may be observed: tendinopathy and tendon rupture, QT prolongation, hypersensitivity reactions, Clostridium difficile-associated diarrhea, peripheral neuropathy, photosensitivity, phototoxicity etc.

Toxicity

The rate of adverse effects increases with higher doses of ketorolac. The most frequently observed adverse effects in patients occurring with an incidence of greater than 10% include: abdominal pain, dyspepsia, nausea, and headaches. Most adverse effects associated with short term use are mild in nature, related to the gastrointestinal tract and nervous system, and occur in roughly 39% of patients. Common symptoms of ketorolac overdose include nausea, vomiting, epigastric pain, gastrointestinal bleeding, lethargy and drowsiness. More rare symptoms of overdose include acute renal failure, hypertension, respiratory depression, and coma.

Ketorolac is classified as Pregnancy Category C since there is a lack of evidence demonstrating safety in pregnant women. NSAIDs including ketorolac increase the risk of premature closure of the fetal ductus arteriosus in the 3rd trimester; therefore, beginning at 30 weeks gestation, pregnant women should avoid ketorolac.

Ketorolac has been shown to be excreted in breast milk, and although available data has not demonstrated any adverse effects in nursing infants, practitioners should proceed with caution when suggesting ketorolac for nursing mothers. The benefits should outweigh the risks and the mother should be counselled to monitor the infant closely and to contact the infant's healthcare provider should any adverse effects arise.

Women who are trying to conceive are not advised to take ketorolac since it's effect on prostaglandin synthesis may impair fertility.

Symptoms of overdose include CNS and gastrointestinal effects such as decreased activity, somnolence, tremor, convulsions, vomiting, and diarrhea. The minimal lethal intravenous dose in mice and rats is 100 mg/kg.

Precaution

Patients over the age of 65 years may be at a greater risk of experiencing adverse events than younger patients. Ketorolac tromethamine can cause gastro-intestinal irritation, ulcers or bleeding in patients with or without a history of previous symptoms. Bronchospasm may be precipitated in patients with a history of asthma. Since ketorolac tromethamine and its metabolites are excreted primarily by the kidney, patients with moderate to severe impairment of renal function (serum creatinine greater than 160 micromol/l) should not receive. Fluid retention and oedema have been reported with the use of Ketorolac tromethamine.

Moxifloxacin should be discontinued at the first appearance of a skin rash or any other sign of hypersensitivity. Moxifloxacin should be discontinued if the patient experiences pain, swelling, inflammation or rupture of a tendon.

Interaction

Ketorolac tromethamine should not be used with other NSAIDs or in patients receiving aspirin because of the potential for additive side effects. Care should be taken when administering Ketorolac tromethamine with anti-coag ulants since co-administration may cause an enhanced anti-coagulant effect. Ketorolac tromethamine and other non-steroidal anti-inflammatory drugs can reduce the anti hypertensive effect of beta-blockers and may increase the risk of renal impairment when administered concurrently with ACE inhibitors, particularly in volume depleted patients. Caution is advised when methotrexate is administered concurrently, since some prostaglandin synthesis inhibiting drugs have been reported to reduce the clearance of methotrexate, and thus possibly enhance its toxicity. Probenecid should not be administered concurrently with ketorolac tromethamine because of increases in ketorolac plasma level and half-life.

No quinolone should be co-administered with any solution containing multivalent cations (e.g. magnesium) through the same intravenous line. Antacids, iron and adsorbents reduce absorption of Moxifloxacin. NSAID may increase the risk of CNS stimulation. Warfarin may increase the risk of bleeding.

Volume of Distribution

The apparent volume of distribution of ketorolac in healthy human subjects is 0.25 L/kg or less.

• 1.7 to 2.7 L/kg

Elimination Route

Ketorolac is rapidly, and completely absorbed after oral administration with a bioavailability of 80% after oral administration. Cmax is attained 20-60 minutes after administration, and after intramuscular administration, the area under the plasma concentration-time curve (AUC) is proportional to the dose administered.

After intramuscular administration, ketorolac demonstrates a time to maximal plasma concentration (tmax) of approximately 45-50 minutes, and a tmax of 30-40 minutes after oral administration. The rate of absorption may be reduced by food; however, the extent of absorption remains unaffected.

Well absorbed from the gastrointestinal tract. Absolute oral bioavailability is approximately 90%. Food has little effect on absorption.

Half Life

Ketorolac tromethamine is administered as a racemic mixture, therefore the half-life of each enantiomer must be considered. The half life of the S-enantiomer is ~2.5 hours, while the half life of the R-enantiomer is ~5 hours. Based on this data, the S enantiomer is cleared about twice as fast as the R enantiomer.

11.5-15.6 hours (single dose, oral)

Clearance

The plasma clearance of ketorolac is 0.021 to 0.037 L/h/kg. Further, studies have illustrated that clearance of oral, IM and IV doses of ketorolac are comparable which suggests linear kinetics. It should also be noted that clearance in children is about double the clearance found in adults.

• 12 +/- 2 L/hr

Elimination Route

Ketorolac is primarily renally eliminated and approximately 92% of the dose can be recovered in the urine with 60% of this proportion recovered unchanged, and 40% recovered as metabolites. In addition 6% of a single dose is eliminated in the feces.

Approximately 45% of an oral or intravenous dose of moxifloxacin is excreted as unchanged drug (~20% in urine and ~25% in feces).

Pregnancy & Breastfeeding use

Safety in human pregnancy has not been established. Ketorolac has been detected in human milk at low levels. Ketorolac is therefore contraindicated during pregnancy, labour or delivery, or in mothers who are breast feeding.

Pregnancy Category C. Moxifloxacin is not recommended during pregnancy & lactation.

Contraindication

Ketorolac Tromethamine is contraindicated in patients with known hypersensitivity to NSAIDs and any of the components of Ketorolac Tromethamine. Moreover, the patient with the history of asthma, nasal polyp, angioedema, peptic ulcer and bleeding, bleeding disorders are contraindicated for this drug.

Moxifloxacin is contraindicated in persons with a history of hypersensitivity to Moxifloxacin or any member of the quinolone class of antimicrobial agents and any component of this formulation.

Special Warning

Elderly: No adjustment of dosage is required in the elderly.

Children: Efficacy and safety of Moxifloxacin IV infusion in children and adolescent have not been established.

Acute Overdose

Symptoms: Abdominal pain, nausea, vomiting, hyperventilation, peptic ulceration, erosive gastritis and renal dysfunction.

Management: Symptomatic and supportive treatment. Consider gastric lavage or admin of activated charcoal within 1 hr of ingestion.

In the events of an acute overdose, the stomach should be emptied. The patient should be kept under observation and appropriate hydration should be maintained.
