Generic Rulide Information

Introduction

Rulide is an oral antibacterial medication marketed in Hong Kong for the treatment of bacterial infections of the respiratory tract, ear, sinus, and skin. The product contains the macrolide antibiotic roxithromycin as its sole active compound and belongs to the broader class of macrolide antibacterials. Roxithromycin exhibits a broad spectrum of activity against Gram‑positive and selected Gram‑negative organisms, making it a valuable option when first‑line agents are unsuitable or when resistance patterns favor its use.

What is Rulide?

Rulide is a tablet formulation that delivers 150 mg of roxithromycin per tablet. It is manufactured by pharmaceutical companies licensed to supply the Hong Kong market; the specific manufacturer may vary by import batch but all products meet the standards set by the Hong Kong Pharmacy and Poisons Board. Roxithromycin was originally developed in the early 199s as a semi‑synthetic derivative of erythromycin, designed to improve acid stability and gastrointestinal tolerance.

Rulide is one of several commercially available brands that contain roxithromycin; other well‑known brand names include Rulox, Roxiton, and Roxithromycin Sandoz. Our online pharmacy provides this generic formulation as a cost‑effective alternative to the brand‑name products while delivering identical therapeutic activity.

How Rulide Works

Roxithromycin, like other macrolides, binds to the 50 S subunit of bacterial ribosomes. This binding interferes with the translocation step of protein synthesis, preventing the addition of new amino acids to the nascent peptide chain. The inhibition is bacteriostatic for most susceptible organisms but can become bactericidal at higher concentrations or in high‑inoculum infections.

Because roxithromycin is acid‑stable, it reaches peak plasma concentrations within 2–3 hours after oral ingestion. The drug distributes extensively into lung tissue, sinus mucosa, and middle‑ear fluids, achieving concentrations that exceed the minimum inhibitory concentrations (MICs) for common respiratory pathogens. It is metabolized minimally in the liver and excreted primarily unchanged in bile, providing a relatively long elimination half‑life of 12–14 hours, which supports a once‑ or twice‑daily dosing schedule.

Conditions Treated with Rulide

• Acute bacterial sinusitis – roxithromycin covers Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, organisms frequently implicated in Hong Kong’s humid climate.
• Community‑acquired pneumonia (CAP) – effective against atypical pathogens such as Mycoplasma pneumoniae and Chlamydophila pneumoniae in addition to typical streptococci.
• Acute otitis media – penetrates middle‑ear fluid, targeting the same spectrum as in sinusitis.
• Uncomplicated skin and soft‑tissue infections – active against Staphylococcus aureus (including many macrolide‑susceptible strains) and streptococci.

These indications are supported by the drug’s inclusion in the Hong Kong Hospital Authority’s formulary for selected respiratory and skin infections, especially when patients have a known macrolide sensitivity or when tetracyclines are contraindicated.

Suitable Candidates for Rulide Treatment

• Adults (≥ 18 years) with a confirmed or strongly suspected bacterial infection matching the approved indications.
• Patients who are allergic to penicillins or have experienced gastrointestinal intolerance to erythromycin, as roxithromycin is generally better tolerated.
• Individuals requiring a convenient dosing regimen (once or twice daily) due to work or travel commitments.

Contraindications / Situations to avoid Rulide

• Known hypersensitivity to roxithromycin, erythromycin, or any other macrolide.
• Severe hepatic impairment (Child‑Pugh C), because drug clearance may be markedly reduced.
• Concomitant use of drugs that strongly inhibit CYP3A4 (e.g., clarithromycin, ketoconazole) where a clinically significant interaction is expected.

Risks, Side Effects, and Interactions

Common

• Nausea, abdominal discomfort, or diarrhoea (generally mild and transient).
• Altered taste (metallic or bitter sensation).
• Headache.

Rare

• Elevated liver enzymes (transient rises in ALT/AST).
• Skin rash, pruritus, or mild urticaria.
• Vestibular disturbances (dizziness, vertigo).

Serious

• Clostridioides difficile‑associated diarrhoea – may occur weeks after therapy and requires urgent medical evaluation.
• Hepatotoxicity – rare cases of clinically significant hepatitis reported, especially in patients with pre‑existing liver disease.
• QT‑interval prolongation – macrolides can affect cardiac repolarisation; caution is advised in patients with known arrias or on other QT‑prolonging agents.

Clinically Relevant Drug–Drug Interactions

• CYP3A4 inhibitors (e.g., clarithromycin, azole antifungals, ritonavir) – may increase roxithromycin plasma levels, raising the risk of QT prolongation and hepatotoxicity.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine, St. John’s wort) – may lower roxithromycin concentrations, reducing efficacy.
• Warfarin – macrolides can potentiate anticoagulation; monitor INR closely if co‑administered.
• Theophylline – roxithromycin may increase serum theophylline levels; dose adjustment may be required.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing – 150 mg tablet taken once daily for uncomplicated sinusitis, otitis media, or skin infections; 150 mg twice daily for community‑acquired pneumonia or infections requiring higher tissue concentrations. Typical treatment courses last 5–7 days, extending to 10–14 days for more severe infections.
• Missed dose – Take the missed tablet as soon as it is remembered unless the next scheduled dose is within 4 hours; in that case, skip the missed dose and resume the regular schedule. Do not double‑dose.
• Overdose – Symptoms may include nausea, vomiting, abdominal pain, and dizziness. While roxithromycin presents low acute toxicity, seek medical attention promptly for supportive care. Activated charcoal may be considered if presentation is within one hour of ingestion.
• Food and alcohol – Roxithromycin can be taken with or without food; a high‑fat meal may slightly delay absorption but does not affect overall exposure. Moderate alcohol consumption does not produce a known interaction, but excessive alcohol should be avoided in patients with liver disease.

FAQ

• What is the typical appearance of a Rulide tablet?
  Rulide tablets are round, film‑coated, and imprinted with “150 R” on one side. The coating is usually white or off‑white, indicating compliance with standard pharmaceutical appearance guidelines.

• Can Rulide be stored in a humid environment such as a Hong Kong bathroom?
  The medication should be kept in a dry place at 15–30 °C. High humidity can degrade the film coating and affect tablet integrity; therefore, storage in a bathroom cabinet is not recommended.

• Does roxithromycin have any effect on oral contraceptives?
  Macrolides can modestly increase plasma concentrations of estrogen‑containing contraceptives, but the clinical significance is low. Nonetheless, women using combined oral contraceptives should be aware of the potential for reduced efficacy with strong CYP3A4 inducers, not with roxithromycin itself.

• Is there a known resistance trend for roxithromycin in Hong Kong?
  data from the Hong Kong Infectious Disease Branch indicate that macrolide resistance among Streptococcus pneumoniae isolates has risen modestly over the past decade, reaching approximately 15 % in community isolates. This underscores the importance of susceptibility testing when possible.

• How does roxithromycin compare with azithromycin for respiratory infections?
  Both are macrolides with similar spectra, but roxithromycin has a longer half‑life, allowing twice‑daily dosing, whereas azithromycin is often dosed once daily but for a shorter course. Clinical efficacy is comparable; selection often depends on patient tolerance, drug‑interaction profile, and local resistance patterns.

• Can I travel with Rulide in my hand luggage?
  Yes. When traveling by air, keep the tablets in their original packaging with a copy of the prescription or a doctor’s note if requested. The dosage form is stable at cabin temperature and does not require special handling.

• Are there any excipients in Rulide that could cause allergic reactions?
  Inactive ingredients typically include lactose, magnesium stearate, and microcrystalline cellulose. Patients with lactose intolerance generally tolerate these amounts, but individuals with documented hypersensitivity to any of these excipients should consult their pharmacist before use.

• What are the legal limits for importing Rulide for personal use into Hong Kong?
  Hong Kong customs permits the import of a 30‑day supply of prescription medicines for personal use, provided the medication is for an individual, accompanied by a valid prescription, and is not a controlled substance. Our online pharmacy ensures compliance with these regulations.

• Does roxithromycin interfere with drug testing for employment?
  Roxithromycin is not a prohibited substance in standard occupational drug‑screening panels. It will not produce a positive result for commonly screened drugs of abuse.

• Is there a pediatric formulation of roxithromycin available in Hong Kong?
  A pediatric suspension (75 mg/5 mL) exists in some markets, but it is not widely marketed in Hong Kong. Rulide is approved for adult use only; dosing for children should be determined by a qualified pediatrician when a suspension is prescribed.
