Makcin

Clarithromycin, the active ingredient in Makcin, is a macrolide antibiotic presented as an oral dosage form for oral use. It treats a range of bacterial infections, including respiratory, sinus, and skin infections, and is used in combination regimens for Helicobacter pylori eradication.

GNH USA supplies Makcin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Clarithromycin is employed to treat bacterial infections affecting the respiratory tract, sinuses, skin and gastrointestinal system. - Community‑acquired pneumonia: eradicates the causative bacteria and improves lung function. - Acute bacterial sinusitis: reduces sinus inflammation and clears infection. - Acute bacterial exacerbations of chronic bronchitis: shortens symptom duration and prevents complications. - Skin and soft‑tissue infections: eliminates pathogenic organisms and promotes wound healing. - Helicobacter pylori eradication regimens: used in combination therapy to achieve bacterial clearance and reduce ulcer recurrence.

Clarithromycin may cause a range of adverse reactions, from mild to severe.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Diarrhea: frequent loose stools. - Abdominal pain: cramping or discomfort. - Taste disturbance: altered or metallic taste. - Headache: mild to moderate intensity. - Vomiting: occasional episodes.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - QT prolongation: potential cardiac arrhythmia risk. - Clostridioides difficile‑associated diarrhea: severe colitis. - Hepatic dysfunction: elevated liver enzymes or jaundice. - Cardiac arrhythmias: irregular heart rhythms beyond QT changes. - Severe skin reactions: such as Stevens‑Johnson syndrome.

Before initiating clarithromycin therapy, consider the following precautions. - Assess renal function: adjust use in patients with impaired kidney function. - Monitor liver enzymes: watch for hepatic toxicity during treatment. - Avoid in known macrolide hypersensitivity: discontinue if allergic reaction occurs. - Evaluate QT interval: perform ECG in patients at risk of cardiac arrhythmias. - Use with caution in pregnancy: only if benefits outweigh potential risks. - Store at room temperature: keep in the original container, protect from moisture.

Clarithromycin interacts with several medicines; some require avoidance while others need monitoring.

Major Interactions (Avoid): - Cisapride: may cause serious cardiac arrhythmias. - Pimozide: increased risk of QT prolongation. - Terfenadine: risk of fatal cardiac events.

Moderate Interactions (Monitor Closely): - Statins (e.g., simvastatin): increased plasma concentrations. - Warfarin: enhanced anticoagulant effect. - Theophylline: elevated serum levels leading to toxicity.
