HsQuin represents a significant advancement in the treatment of complex and resistant bacterial infections, offering a potent, broad-spectrum quinolone antibiotic designed for clinical efficacy where other treatments may falter. Engineered with a refined molecular structure, it provides enhanced bacterial penetration and sustained therapeutic levels, making it a cornerstone in managing severe respiratory, urinary, and intra-abdominal infections. Its targeted mechanism minimizes the development of resistance, ensuring reliable outcomes in both hospital and outpatient settings. Trusted by infectious disease specialists, HsQuin stands as a critical tool in modern antimicrobial stewardship.
Features
- Active ingredient: Levofloxacin hemihydrate (750 mg per tablet)
- Pharmaceutical form: Film-coated tablets
- Broad-spectrum activity against Gram-positive and Gram-negative aerobes
- High oral bioavailability (>99%)
- Extended half-life (~7–8 hours) allowing for once-daily dosing
- Stable under varied pH conditions
- Manufactured under cGMP standards
Benefits
- Effectively eradicates multidrug-resistant pathogens, reducing treatment failure rates.
- Simplified once-daily regimen enhances patient adherence and convenience.
- Rapid onset of action leads to quicker symptom relief and shorter hospital stays.
- Lower risk of resistance development compared to earlier generation quinolones.
- Suitable for both monotherapy and combination regimens in severe infections.
- Cost-effective due to reduced need for intravenous therapy in eligible patients.
Common use
HsQuin is indicated for the treatment of adults with complicated urinary tract infections, acute pyelonephritis, community-acquired pneumonia, and complicated skin and skin structure infections. It is also used in post-exposure prophylaxis for inhalation anthrax and as part of combination therapy for certain types of intra-abdominal infections. Its use is generally reserved for cases where susceptibility testing confirms efficacy or where first-line agents are contraindicated or ineffective.
Dosage and direction
The recommended dosage for most indications is 750 mg orally once daily for 5–14 days, depending on infection severity and clinical response. Administer with a full glass of water, with or without food, though taking it 2 hours before or after antacids or multivitamins containing iron or zinc is advised. For patients with renal impairment (CrCl <50 mL/min), dosage adjustment is necessary—typically 750 mg initially, followed by 500 mg daily. Complete the full course even if symptoms improve earlier.
Precautions
Avoid unnecessary exposure to sunlight or UV rays due to photosensitivity risk. Use with caution in patients with a history of tendon disorders, as quinolones may increase the risk of tendonitis or rupture. Monitor for neurological symptoms such as dizziness or seizures, especially in elderly patients or those with CNS disorders. Hydration should be maintained to prevent crystalluria. Not recommended during pregnancy or lactation unless potential benefits outweigh risks.
Contraindications
HsQuin is contraindicated in patients with known hypersensitivity to levofloxacin, other quinolones, or any component of the formulation. It should not be used in patients with a history of tendonitis or tendon rupture associated with quinolone use. Avoid concurrent use with tizanidine. Contraindicated in patients with myasthenia gravis due to risk of exacerbation.
Possible side effects
Common side effects (≥1%) include nausea, diarrhea, headache, insomnia, and constipation. Less frequently, dizziness, abdominal pain, and rash may occur. Serious but rare adverse effects include tendon rupture, peripheral neuropathy, CNS effects (e.g., seizures, psychosis), QT prolongation, and hepatotoxicity. Discontinue immediately if signs of hypersensitivity, such as swelling or difficulty breathing, appear.
Drug interaction
HsQuin may interact with antacids, sucralfate, iron, or zinc supplements, reducing its absorption—space administration by at least 2 hours. Concurrent use with corticosteroids increases tendon rupture risk. May enhance effects of warfarin; monitor INR closely. Can prolong QT interval; avoid with other QT-prolonging drugs like antiarrhythmics or antipsychotics. Theophylline levels may increase; monitor and adjust dose if needed.
Missed dose
If a dose is missed, take it as soon as remembered unless it is nearly time for the next dose. Do not double the dose to catch up. Resume the regular dosing schedule. Consistent timing helps maintain therapeutic levels and efficacy.
Overdose
Symptoms of overdose may include nausea, vomiting, tremors, seizures, or confusion. Management is supportive; ensure hydration and monitor ECG for QT prolongation. Hemodialysis removes approximately 10% of the drug and may be considered in severe cases. There is no specific antidote.
Storage
Store at room temperature (15–30°C or 59–86°F) in the original container, protected from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
“In my practice, HsQuin has been invaluable for treating resistant Pseudomonas infections in cystic fibrosis patients. The once-daily dosing improves compliance significantly.” — Dr. Elena Rostova, Infectious Disease Specialist
“Used it for a case of complicated UTI with excellent results. No side effects noted, and culture confirmed eradication at follow-up.” — Clinical Pharmacist, Metro General Hospital
“Effective, but caution advised in elderly patients—monitor for tendon and CNS effects. Overall, a reliable option when first-line fails.” — Dr. Mark Thiel, Internal Medicine
