Lomefloxacin: Brands, Price & Uses in Bangladesh

Lomefloxacin is a synthetic broad-spectrum fluoroquinolone antibiotic. Its uses can be classified by strength of evidence as follows:

Established / historically FDA-approved uses (oral, systemic)

• Acute bacterial exacerbation of chronic bronchitis caused by susceptible strains of organisms such as Haemophilus influenzae, Moraxella catarrhalis, or Streptococcus pneumoniae.
• Uncomplicated urinary tract infection (cystitis) caused by susceptible organisms including Escherichia coli, Klebsiella pneumoniae, and other Gram-negative uropathogens.
• Complicated urinary tract infection and acute pyelonephritis caused by susceptible organisms.
• Pre-operative prophylaxis to reduce the incidence of postoperative infection in patients undergoing transurethral surgical procedures.
• Uncomplicated urethral and cervical gonorrhea caused by susceptible Neisseria gonorrhoeae — this is a narrower, non-first-line indication historically used only where preferred first-line regimens were unsuitable, and is not consistent with most current gonorrhea treatment guidelines.

Ophthalmic use

Where an ophthalmic (eye drop) formulation of Lomefloxacin is available, it is indicated for topical treatment of bacterial conjunctivitis caused by susceptible organisms.

Important note on current use

Because of its comparatively pronounced photosensitivity risk and the availability of other fluoroquinolones with better-characterized safety profiles, Lomefloxacin is not commonly used today and is not listed as an actively marketed product in several major drug databases, including in Bangladesh. Lomefloxacin should be prescribed only when a physician has confirmed local product availability and determined that it is an appropriate, susceptibility-guided choice — as with all fluoroquinolones, reserved for infections where more narrow-spectrum agents are not suitable, in line with antibiotic stewardship principles.

Important: Take Lomefloxacin exactly as prescribed by your physician; do not stop, extend, skip doses, or share this medicine with others without medical advice, even if symptoms improve before the course is finished.

Adult oral dosing by indication

Renal impairment

Because Lomefloxacin is eliminated mainly by the kidneys, dose adjustment is required in patients with reduced renal function (e.g. creatinine clearance below approximately 40 mL/min), typically by giving a normal loading dose followed by a reduced maintenance dose or extended dosing interval, as directed by the physician.

Hepatic impairment

No specific dose adjustment is well established for hepatic impairment alone, but caution and physician judgment are advised.

Ophthalmic use (where marketed)

Typically one to two drops instilled into the affected eye(s) as directed by the physician; the exact frequency and duration should follow the specific product label.

Common side effects of Lomefloxacin may include:

• Nausea, vomiting, diarrhea, abdominal discomfort
• Headache, dizziness, insomnia
• Photosensitivity/phototoxic skin reactions (notably more frequent and can be more severe with Lomefloxacin than with several other fluoroquinolones — see Precautions and Warnings)
• Rash or pruritus

Serious side effects (fluoroquinolone class effects, applicable to systemic/oral use) that require prompt medical attention include:

• Tendinitis and tendon rupture
• Peripheral neuropathy (numbness, tingling, weakness, which may be irreversible)
• Central nervous system effects — seizures, confusion, hallucinations, increased intracranial pressure, tremors
• Exacerbation of myasthenia gravis symptoms, including muscle weakness affecting breathing
• QT interval prolongation and, rarely, serious ventricular arrhythmia
• Severe hypersensitivity reactions, including anaphylaxis and severe skin reactions (e.g. Stevens–Johnson syndrome)
• Clostridioides difficile-associated diarrhea/colitis
• Blood glucose disturbances (hyper- or hypoglycemia)
• Aortic aneurysm and dissection (rare, mainly in predisposed patients)

For the ophthalmic form, adverse effects are generally limited to local eye irritation, burning, or discomfort, with much lower risk of the systemic effects listed above.
