Prulifloxacin (600mg) ' ,.

Prulifloxacin (600 mg) is a fluoroquinolone antibacterial agent known for its high potency and extended duration of action against a wide range of gram-positive and gram-negative bacteria.

It was developed over two decades ago by Nippon Shinyaku Co. and was patented in Japan in 1987 and in the United States in 1989. It has been approved for the treatment of uncomplicated and complicated urinary tract infections, community-acquired respiratory tract infections in Italy and gastroenteritis, including infectious diarrheas, in Japan.

Brand Names Around the World

Prulifloxacin is marketed in Japan and Italy as Quisnon (Nippon Shinyaku); Sword (Meiji); Unidrox (Angelini); Prixina (Angelini) and Glimbax (ITF Hellas) in Greece and generic as Pruquin.In India, it is available as PRULITECH 600 among other brands.

How Does PRULITECH 600 Work? (Mechanism of Action)

Understanding how PRULITECH 600 works helps patients appreciate its effectiveness in combating bacterial infections.

Like other fluoroquinolones, Prulifloxacin prevents bacterial DNA replication, transcription, repair and recombination through inhibition of bacterial DNA gyrase. Quinolones and fluoroquinolones are bactericidal drugs, eradicating bacteria by interfering with DNA replication.

Prulifloxacin targets bacterial enzymes, specifically DNA gyrase and topoisomerase IV. These enzymes play crucial roles in bacterial DNA replication, transcription, and repair. By inhibiting these enzymes, Prulifloxacin disrupts the bacterial DNA processes, leading to cell death.

For many gram-negative bacteria, DNA gyrase is the target, whereas topoisomerase IV is the target for many gram-positive bacteria.

Prulifloxacin stops the bacteria from multiplying in your body and eventually kills them.

Key Points of Mechanism:

• Inhibits bacterial DNA gyrase enzyme
• Inhibits topoisomerase IV enzyme
• Prevents DNA replication, transcription, and repair
• Results in bacterial cell death
• Bactericidal action (kills bacteria rather than just stopping growth)

Clinical Uses and Indications

PRULITECH 600 is prescribed for a wide range of bacterial infections. Prulifloxacin (600mg) is prescribed for several types of bacterial infections. These include respiratory tract infections, urinary tract infections, and gastrointestinal infections. Its broad-spectrum activity ensures effective eradication of the bacteria causing these conditions, helping patients recover faster and reducing the risk of complications.

Primary Indications:

A. Urinary Tract Infections (UTIs)

The antibacterial agent prulifloxacin, a prodrug of ulifloxacin, is indicated in the treatment of acute lower urinary tract infections, acute exacerbation of chronic bronchitis and acute bacterial rhinosinusitis.

• Acute uncomplicated lower urinary tract infections (simple cystitis)
• Complicated urinary tract infections
• Both community-acquired and nosocomial UTIs

B. Respiratory Tract Infections

In well-designed clinical trials, prulifloxacin 600 mg administered once daily for 10 days in patients with AECB showed good clinical and bacteriological efficacy (similar to that of ciprofloxacin or co-amoxiclav). In particular, the clinical response rates were favourable in all clinical trials, with eradication rates in patients with pneumococcal infections at least as high as the comparators.

• Acute exacerbation of chronic bronchitis (AECB)
• Community-acquired respiratory tract infections
• Acute bacterial rhinosinusitis
• Pneumonia

C. Gastrointestinal Infections

• Infectious diarrhea
• Gastroenteritis caused by susceptible bacteria

Bacterial Coverage

Ulifloxacin is generally more active in vitro than other fluoroquinolones against a variety of clinical isolates of Gram-negative bacteria, including community and nosocomial isolates of Escherichia coli, Klebsiella spp., Proteus, Providencia and Morganella spp., Moraxella catarrhalis and Haemophilus spp.2

Gram-positive organisms, including methicillin- or oxacillin-susceptible Staphylococcus aureus, Enterococcus spp. and Streptococcus pneumoniae, are susceptible to ulifloxacin.

Note: Prulifloxacin is an antibacterial medicine that acts only against bacterial infections and not against viral infections, causing cough, cold and flu.

Dosage and Administration Guidelines

Recommended Dosage

The recommended dosage of Prulifloxacin (600mg) is typically one tablet taken once daily. It is crucial to follow the healthcare provider's instructions regarding the duration of the treatment.

The 600 mg once-daily dose showed the best risk/benefit ratio, and was selected for use in the pivotal clinical trials.

Duration of Treatment

Good clinical and bacteriological efficacy (similar to that of ciprofloxacin, amoxicillin/clavulanic acid or pefloxacin) was seen with prulifloxacin 600 mg once daily for 10 days in patients with acute exacerbations of chronic bronchitis or complicated lower urinary tract infections (UTIs), and with single-dose prulifloxacin 600 mg in acute, uncomplicated lower UTIs.

Administration Tips

Take Prulifloxacin as instructed by the doctor. Do not take in larger amounts than advised/prescribed. Ensure that the treatment course is completed. Do not stop the use of this medicine without consulting your doctor.

Do not stop taking Prulifloxacin and complete the full course of treatment even if you feel better. Your symptoms may improve before the infection is completely cured.

Missed Dose

If you miss a dose of Prulifloxacin, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.

Dosage Adjustment for Renal Impairment

For patients with severe renal impairment, a dose of 300 mg was administered daily for 7 days, while the same 600 mg dose was administered daily for 7 days to subjects with normal renal function and patients with mild and moderate renal impairment.

Prulifloxacin is a safe quinolone and is well tolerated in both subjects with normal renal function and patients with impaired renal function, requiring a minimal dosage adjustment only in patients with severe renal impairment.

Pharmacokinetics: How the Body Processes PRULITECH 600

Understanding the pharmacokinetics of PRULITECH 600 helps explain why it's effective and requires only once-daily dosing.

Absorption

PUFX, the prodrug of UFX, offers a clear advantage over the active metabolite with regard to absorption after oral administration. PUFX is absorbed in the upper small intestine and then metabolized to UFX by esterases, mainly paraoxonase, partly in the intestinal membrane and mostly in the portal blood and the liver (first pass or presystemic metabolism).

Distribution

Ulifloxacin is ≈45% bound to serum proteins in vivo. It is extensively distributed throughout tissues and shows good penetration into many body tissues.

In addition, it penetrates extensively into lung tissues.

Metabolism

After absorption from the gastrointestinal tract, prulifloxacin undergoes extensive first-pass metabolism (hydrolysis by esterases, mainly paraoxonase to form ulifloxacin, the active metabolite).

Peak Concentration

Prulifloxacin 600 mg achieves peak plasma concentration (Cmax) of ulifloxacin (1.6μg/mL) in a median time to Cmax (tmax) of 1 hour.

Elimination

The drug has a long elimination half-life, allowing once-daily administration.

The elimination half-life (t1/2) of ulifloxacin after single-dose prulifloxacin 300–600 mg ranged from 10.6 to 12.1 hours.

Benefits of PRULITECH 600

1. Once-Daily Convenience

Since good patient compliance is a key factor in the successful treatment of any infection, the once daily treatment with prulifloxacin may have some compliance advantages compared to the twice-daily treatment with agents such as ciprofloxacin or co-amoxiclav.

2. Comparable Efficacy to Other Antibiotics

Prulifloxacin was generally well tolerated in clinical trials, with a similar tolerability profile to that of ciprofloxacin.

3. Broad-Spectrum Activity

Recent studies have shown that Prulifloxacin is particularly effective in treating infections caused by Gram-negative and Gram-positive bacteria, making it a valuable option in the antibiotic arsenal.

4. Cardiac Safety Profile

Prulifloxacin has a reduced effect on the QTc interval compared to other fluoroquinolones and may be a safer choice for patients with pre-existing risk factors for arrhythmia.

In a randomized, three-period crossover placebo-controlled comparison with moxifloxacin in 48 healthy adults, prulifloxacin 600 mg/day for 5 days had no significant effect on the QT interval individually corrected for heart rate (QTcI). The largest mean increase was 4 ms, well within the range of 0–5 ms, which is considered to carry no risk of torsade de pointes.

5. Excellent Tissue Penetration

Particularly beneficial for respiratory infections due to extensive lung tissue penetration.

Side Effects

Like all medications, PRULITECH 600 may cause side effects in some patients. Being aware of these helps you recognize and address them promptly.

Common Side Effects

Common adverse effects include gastrointestinal disturbances such as nausea, diarrhea, and abdominal pain. Some patients may experience headache, dizziness, or photosensitivity.

You may experience vomiting, headache, dizziness, stomach pain, nausea, diarrhoea, and abnormal liver function tests in some cases.

Serious Side Effects

Serious but rare side effects include tendonitis and tendon rupture, peripheral neuropathy, and central nervous system effects such as seizures and psychosis.

Tendinitis and tendon rupture are serious but infrequent side effects associated with fluoroquinolones, including Prulifloxacin. This risk is higher in older adults, those taking corticosteroids, and patients with a history of tendon disorders. Symptoms like sudden pain, swelling, or movement difficulties in tendons, particularly in the Achilles tendon, should be promptly reported to a healthcare provider.

In rare cases, Prulifloxacin can affect liver function. Symptoms of liver issues include yellowing of the skin or eyes (jaundice), dark urine, severe stomach pain, or persistent nausea/vomiting. Regular monitoring of liver enzymes might be necessary for patients on prolonged therapy.

Allergic Reactions

It is also important to consider potential allergic reactions to Prulifloxacin. Symptoms can range from mild, like itching or hives, to severe, such as difficulty breathing, swelling of the face, lips, tongue, or throat (anaphylaxis). Immediate medical intervention is necessary if an allergic reaction is suspected.

Discontinue Prulif 600mg Tablet and inform your doctor immediately if you get a rash, itchy skin, swelling of face and mouth, or have difficulty in breathing. Diarrhea may occur as a side effect but should stop when your course is complete.

Precautions and Warnings

Tendon Damage Risk

Prulifloxacin may cause tendinitis and tendon rupture in some patients. This risk is especially higher in elderly patients on concomitant corticosteroid treatment.

Use of Prulifloxacin is known to increase the risk of muscle damage, commonly in the ankle (achilies tendon). Muscle damage can happen in people of all ages who take Prulifloxacin.

CNS Disorders

Prulifloxacin should be used with caution in patients with central nervous system disorders due to the increased risk of seizures.

Glucose Monitoring

Prulifloxacin may affect blood glucose levels, and individuals with diabetes or those at risk of developing glucose metabolism disorders should be monitored closely while taking this medication.

G6PD Deficiency

Patients with latent or known deficiencies for the Glucose-6-Phosphate-Dehydrogenase activity are predisposed to hemolytic reactions.

Photosensitivity

Patients must avoid staying outdoors in bright sunlight for prolonged periods as it may increase photosensitivity and cause complications. It may also lead to eczema and high fever.

Myasthenia Gravis

Taking Prulifloxacin may worsen muscle weakness in people with myasthenia gravis (muscle weakness disorder) and cause severe difficulty breathing or death.

Driving and Operating Machinery

You shouldn't drive or operate heavy machinery when under the influence of the medicine as it induces drowsiness and dizziness.

Drug Interactions

PRULITECH 600 may interact with several medications. Always inform your healthcare provider about all medications you are taking.

Major Drug Interactions

Drug interactions include:

• Probenecid: Prulifloxacin urinary excretion decreases when concomitantly administered with probenecid.
• Fenbufen: The concomitant administration of fenbufen can cause increased risk of convulsions.
• Hypoglycemic agents: May cause hypoglycemia in diabetic patients under treatment with hypoglycemic agents.
• Theophylline: May cause a decreased theophylline clearance.
• Warfarin: May enhance the effects of oral anticoagulants such as warfarin and its derivatives.
• Nicardipine: May potentiate the phototoxicity of prulifloxacin.3

The drug can also enhance the effects of oral anticoagulants like warfarin, necessitating close monitoring of coagulation parameters. Furthermore, co-administration with corticosteroids may heighten the risk of tendonitis and tendon rupture.

NSAIDs Interaction

Do not consume Prulifloxacin with Aceclofenac. If concurrent use is essential, watch out for convulsions and seizures and consult your doctor if you experience them.

Mineral Supplements

Ensure a gap of at least 2 hours between taking Prulifloxacin and Calcium. Calcium may reduce blood levels of Prulifloxacin.

Food Interactions

Dairy Products

The impact of milk or yogurt consumption was tested solely in adult volunteers, with effects varying from negative (for ciprofloxacin, norfloxacin, pazufloxacin, and prulifloxacin) to neutral. The impact of milk and yogurt on individual quinolone absorption was generally consistent with the effect of calcium supplements, suggesting that the most possible mechanism of negative interaction could be chelate formation with calcium ions present in dairy products.

Avoid consuming dairy products (e.g., milk, yogurt) or fortified beverages (e.g., calcium-fortified orange juice) within a few hours before or after taking prulifloxacin. Calcium-containing foods and drinks can interfere with the absorption of the medication.

It is recommended not to take dairy products such as milk, yoghurt, and Prulifloxacin as they might decrease the effectiveness of Prulifloxacin. Please maintain a gap of at least 2 hours between both of them.

Alcohol

Alcohol is not known to cause any unpleasant side effects if taken along with Prulifloxacin. But intake of alcohol with Prulifloxacin may damage your liver.

Special Populations

Pregnancy

This medicine is not recommended for use in pregnant women since the safety and efficacy of use are not clinically established.

Breastfeeding

This medicine is not recommended for use in breastfeeding women since the safety and efficacy of use are not clinically established.

Elderly Patients

This medicine should be used with caution in the elderly population due to the increased risk of tendinitis and tendon rupture.

Caution is advised in elderly patients and those with renal impairment, as dosage adjustments may be necessary.

Pediatric Population

This medicine is not recommended for use in children and adolescents due to the increased risk of serious adverse effects.

Patients with Renal Impairment

Dosing adjustments may be necessary for individuals with impaired renal (kidney) function because prulifloxacin is primarily excreted through the kidneys.
