How does 4Quin 5 gm eye ointment work?
- Inhibiting bacterial DNA synthesis: Moxifloxacin works by blocking the bacterial enzymes DNA gyrase and topoisomerase IV, which are essential for bacterial DNA replication, transcription, and repair.
- Preventing bacterial multiplication: By inhibiting these crucial enzymes, the ointment stops bacteria from dividing and repairing themselves.
- Killing infection-causing bacteria: The combined effect of blocking DNA replication and repair leads to bacterial cell death, effectively clearing the infection and relieving symptoms such as pain, redness, swelling, and discharge.
Dosage
- Apply a small amount (about 1 cm) of ointment inside the lower eyelid of the affected eye, 2-3 times a day or as directed by your doctor.
- It is recommended to consult a doctor or medical professional prior to using eye ointment for better results.
- Complete the full course of treatment even if symptoms improve to prevent antibiotic resistance and recurrence of infection.
Uses
- Bacterial conjunctivitis: An infection of the transparent membrane (conjunctiva) that lines the eyelid and covers the white part of the eye, causing redness, pain, and discharge.
- Corneal ulcers: Open sores on the cornea caused by bacterial infection, requiring prompt treatment to prevent complications.
- Post-surgical prophylaxis: Used after eye surgeries such as cataract or corneal refractive procedures to reduce the risk of bacterial infections.
Side Effects
- Eye discomfort or irritation
- Burning or stinging sensation in the eye
- Dry eyes
- Watery eyes
- Eye pain
- Blurred vision (temporary)
- Redness and itching
Interactions
- 4Quin 5 gm may interact with other eye medications. Maintain a time gap of at least 5 minutes between applying different eye drops or ointments.
- Eye ointment should always be applied after eye drops, never before.
- The systemic absorption of 4Quin 5 gm Eye Ointment is minimal, making significant drug interactions with oral medications unlikely, but inform your doctor about all medications you are taking.
- Avoid wearing contact lenses during treatment as they can worsen the infection and cause further irritation.
Pharmacokinetics
Pharmacokinetics of 4Quin 5 gm Eye Ointment involves the absorption of the active component (Moxifloxacin) through the eye tissues, where it produces its antibacterial action. Due to its topical application, systemic absorption is minimal, and the medication primarily acts locally at the site of infection. The complete pharmacokinetic properties of this drug when applied topically to the eye are not extensively documented.
Precautions
- Allergies: Do not use 4Quin 5 gm Eye Ointment if you are allergic to Moxifloxacin, other fluoroquinolone antibiotics, or any ingredients in the formulation.
- Contact lenses: Remove contact lenses before applying the ointment and wait at least 15 minutes before putting them back in. Do not wear contact lenses if you have signs and symptoms of bacterial conjunctivitis.
- Pregnancy and breastfeeding: Use with caution during pregnancy and breastfeeding. Animal studies have shown potential harmful effects on the developing fetus. Consult your doctor before using 4Quin 5 gm Eye Ointment if you’re pregnant or breastfeeding.
Conclusion
4Quin 5 gm Eye Ointment is an effective drug for the treatment of bacterial eye infections, including bacterial conjunctivitis and corneal ulcers. By inhibiting bacterial DNA replication and repair through blocking essential enzymes, this ointment kills infection-causing bacteria and provides relief from symptoms. It is also valuable for preventing infections after eye surgeries. However, for avoiding side effects and ensuring optimal results, it’s essential to adhere to the dosing instructions and precautions. Consult your physician or an eye specialist for specific recommendations and information on using 4Quin 5 gm Eye Ointment.

Antibiotic ointment, effective but messy. Best to use before bedtime because it blurs vision right after applying
