Qxone 500mg Injection

Qxone 500mg Injection contains Ceftriaxone, a third-generation cephalosporin antibiotic intended for the treatment of moderate to severe bacterial infections in adults and children. It is usually administered by intramuscular (IM) or intravenous (IV) injection in hospital or clinical settings.

Ceftriaxone works by interfering with bacterial cell wall formation. It binds to penicillin-binding proteins (PBPs), preventing the synthesis of the cell wall that bacteria need to survive. This causes the bacterial cell to weaken and rupture, resulting in a bactericidal effect.

Qxone 500mg Injection is widely used to treat respiratory tract infections such as pneumonia, serious urinary tract infections, bloodstream infections (septicemia), abdominal infections, skin and soft tissue infections, bone and joint infections, and central nervous system infections such as bacterial meningitis. It is also commonly used in the treatment of typhoid fever, gonorrhoea, and for surgical prophylaxis to prevent post-operative infections.

Because of its long half-life and excellent tissue penetration, Ceftriaxone allows for once-daily dosing in most infections, improving treatment compliance and effectiveness. To ensure optimal results and safety, it should always be used under the supervision of a healthcare professional.

Ceftriaxone works by disrupting bacterial cell wall synthesis

Step-by-step mechanism of action of ceftriaxone involves:

• Entry into the body: After injection (IV or IM), ceftriaxone circulates in the bloodstream and reaches the site of bacterial infection.
• Targeting bacteria: Ceftriaxone penetrates the bacterial cell wall and reaches the inner cell wall layer.
• Binding to PBPs: It binds to penicillin-binding proteins (PBPs), which are enzymes needed to build and maintain the bacterial cell wall.
• Inhibition of cell wall synthesis: By binding to PBPs, ceftriaxone blocks the cross-linking of peptidoglycan chains, an essential step in forming a strong cell wall.
• Weakening of the cell wall: Without proper peptidoglycan cross-linking, the bacterial cell wall becomes weak and unstable.
• Cell lysis: Due to osmotic pressure, the weakened cell wall ruptures.
• Bacterial death: The bacteria die, making ceftriaxone a bactericidal antibiotic. This mechanism makes [MEDICINE_NAME] highly effective against rapidly dividing bacteria.

• Always receive injections from a trained healthcare professional
• Complete the full antibiotic course
• Inform your doctor about any history of allergies
• Report severe diarrhoea immediately
• Do not self-administer or reuse leftover injections

Store below 25°C in a dry place, protected from light. Keep out of reach of children. Reconstituted solutions should be used promptly as directed.

No significant food interactions reported

• Calcium-Containing IV Solutions: Should not be mixed with ceftriaxone
• Blood Thinners: May increase bleeding risk
• Other Antibiotics: May alter effectiveness

• Severe allergy to cephalosporins or penicillins: In patients with a known serious allergy to cephalosporin antibiotics (and sometimes penicillins), ceftriaxone can trigger severe hypersensitivity reactions, so it should be avoided.
• Gallbladder or biliary disease: Ceftriaxone can form calcium–ceftriaxone precipitates in bile, leading to biliary sludge or gallstones, which may worsen existing gallbladder or biliary tract disorders.
• Severe liver and kidney impairment: In patients who have both significant liver and kidney disease, ceftriaxone may accumulate in the body and increase the risk of toxicity, so careful monitoring or dose adjustment is required.

The usual adult dose ranges from 1–2 g once daily, depending on the infection. Severe infections may require higher doses as prescribed by a doctor.

Overdose may cause seizures or severe gastrointestinal symptoms.Immediate medical attention is required.

Since it is administered by healthcare professionals, missed doses are uncommon. If a dose is missed, it should be administered as soon as possible under medical supervision.
