Generic Asacol Information

Introduction

Asacol is an oral medication that contains the anti‑inflammatory compound mesalamine. It belongs to the “Gastro Health, Antibacterial” group, a classification used in Hong Kong to indicate drugs that target the gastrointestinal tract and possess anti‑bacterial or anti‑inflammatory activity. Asacol is marketed primarily for the long‑term management of inflammatory bowel diseases (IBD) such as ulcerative colitis. The product is manufactured by Novartis International AG and is available throughout Hong Kong’s healthcare system, both in hospitals and community pharmacies. In addition to its core indication, clinicians sometimes prescribe Asacol off‑label for maintenance of remission in Crohn’s disease limited to the colon.

What is Asacol?

Asacol is a delayed‑release tablet that delivers mesalamine (5‑aminosalicylic acid) directly to the colon. The preparation uses a pH‑dependent coating that remains intact in the acidic stomach environment and dissolves when the pH reaches 7 or higher, typically in the terminal ileum and colon. The active ingredient, mesalamine, is a derivative of salicylic acid that exerts local anti‑inflammatory effects without significant systemic absorption.

• Classification: 5‑ASA (5‑aminosalicylic acid) derivative, delayed‑release oral tablet.
• Developer: Novartis International AG, headquartered in Basel, Switzerland.
• Regulatory status in Hong Kong: Registered with the Department of Health (DH) as a prescription‑only medicine for ulcerative colitis and certain cases of Crohn’s disease.

How Asacol Works

Mesalamine interferes with several inflammatory pathways that are active in the colonic mucosa. Its principal mechanisms include:

• Inhibition of cyclo‑oxygenase (COX) and lipoxygenase enzymes, reducing the synthesis of prostaglandins and leukotrienes that promote inflammation.
• Scavenging of reactive oxygen species (ROS), thereby limiting oxidative damage to epithelial cells.
• Modulation of nuclear factor‑κB (NF‑κB) signaling, which down‑regulates the transcription of pro‑inflammatory cytokines such as interleukin‑1β, interleukin‑6, and tumor necrosis factor‑α.

Because the drug is released at colonic pH, mesalamine achieves high local concentrations where inflammation resides while systemic exposure remains low. Clinical studies show measurable mucosal healing within 4–8 weeks of consistent therapy, and the therapeutic effect is maintained as long as the drug is taken daily.

Conditions Treated with Asacol

• Ulcerative colitis (UC): First‑line maintenance therapy for patients in remission and for mild‑to‑moderate active disease. Hong Kong reports an estimated UC prevalence of .05 % among adults, making Asacol a widely utilized option in gastroenterology clinics.
• Crohn’s disease limited to the colon: Although not formally approved for all forms of Crohn’s disease, mesalamine‑based agents such as Asacol are occasionally prescribed for colonic involvement when the disease is mild and patients prefer an oral, non‑steroidal option.
• Prevention of postoperative recurrence: After surgical resection of colonic disease, Asacol may be used to reduce the risk of endoscopic recurrence, according to consensus guidelines in Asian IBD networks.

The drug’s utility stems from its targeted anti‑inflammatory activity, ease of oral administration, and favorable safety profile compared with systemic corticosteroids or immunosuppressants.

Patient Groups Most Likely to Benefit

• Adults with confirmed ulcerative colitis who have achieved clinical remission and require maintenance therapy to prevent relapse.
• Patients intolerant to systemic steroids or who wish to avoid long‑term immunosuppression.
• Individuals with mild‑to‑moderate colonic Crohn’s disease where a localized anti‑inflammatory approach is appropriate.
• Post‑surgical patients after colectomy or segmental resection, when the goal is to maintain mucosal quiescence.

Contra‑indications or cautionary use include: known hypersensitivity to mesalamine or salicylates, severe renal impairment (eGFR < 30 mL/min/1.73 m²), and active severe disease requiring rapid induction with biologics or systemic steroids. Pregnant or breastfeeding women should discuss risks with their physician, as safety data are limited but generally suggest no teratogenic effect at standard doses.

Risks, Side Effects, and Interactions

Common

• Headache
• Nausea or mild abdominal pain
• Flatulence and bloating
• Mild rash or itching

These events are usually transient and resolve without discontinuation of therapy.

Rare

• Pancreatitis (incidence < .1 %)
• Photosensitivity reactions
• Elevated liver enzymes (ALT/AST)

Patients experiencing persistent gastrointestinal upset or skin changes should be evaluated for alternative dosing or formulation.

Serious

• Renal toxicity: Acute interstitial nephritis or decline in renal function has been reported, particularly in patients with pre‑existing kidney disease. Routine monitoring of serum creatinine is recommended every 3–6 months.
• Severe hypersensitivity: Anaphylaxis, Stevens‑Johnson syndrome, or toxic epidermal necrolysis require immediate cessation and emergency care.
• Colitis flare: Paradoxical worsening of IBD symptoms may occur; if symptoms intensify, seek medical review promptly.

Drug–Drug Interactions

• Non‑steroidal anti‑inflammatory drugs (NSAIDs): May increase risk of renal impairment when combined with mesalamine.
• Azathioprine or 6‑mercaptopurine: No direct pharmacokinetic interaction, but combined immunosuppression may modify infection risk.
• Anticoagulants (warfarin): Rare reports of enhanced anticoagulant effect; monitor INR if co‑administered.
• Antacids containing aluminum or magnesium: May affect the coating dissolution; spacing doses by at least 2 hours is advisable.

Patients should provide a full medication list, including over‑the‑counter products and herbal supplements, the prescribing clinician.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for ulcerative colitis: 2.4 g per day, administered as either a single 2.4 g tablet or divided into two 1.2 g tablets taken with breakfast and dinner. Dose may be adjusted up to 4.8 g/day in refractory cases, as directed by a gastroenterologist.
• Crohn’s disease (colonic involvement): 2.4 g daily, with similar split‑dose schedule.

Missed dose:
If a dose is missed within 12 hours, take it as soon as remembered. If it is closer to the next scheduled dose, skip the missed tablet and continue the regular dosing regimen. Do not double‑dose.

Overdose:
Symptoms may include nausea, vomiting, abdominal cramps, and mild electrolyte disturbances. In the event of suspected overdose, seek immediate medical attention; supportive care and observation are the mainstays of management.

Food and alcohol:
Asacol may be taken with or without food; however, a high‑fat meal can delay tablet dissolution slightly, which does not affect overall efficacy. Moderate alcohol consumption does not contraindicate use but excessive intake may aggravate gastrointestinal irritation.

Comorbidities:
Patients with renal or hepatic impairment require dose adjustment and close laboratory monitoring. Those with a history of sulfonamide allergy should be evaluated carefully before initiation.

  Yes, Asacol is a prescription‑only medication under Hong Kong law. Our online pharmacy arranges the necessary prescription electronically after verification by a qualified healthcare professional, so a local paper prescription is not needed for the order.

• Can Asacol be stored in the refrigerator?
  No, Asacol tablets should be stored at controlled room temperature (15 °C–30 °C). Refrigeration may affect the integrity of the pH‑dependent coating and reduce drug efficacy.

• What packaging does Asacol come in when ordered online?
  The medication is supplied in sealed, tamper‑evident blister packs within a discreet, opaque box. Each pack contains the prescribed quantity of tablets, with a printed leaflet in English and Traditional Chinese.

• Are there differences between Asacol formulations sold in the US, EU, and Asia?
  The core active ingredient, mesalamine, is identical across regions. However, coating polymers and excipients may vary slightly to meet local regulatory standards. All formulations are designed to dissolve at colonic pH and provide comparable clinical outcomes.

• Is Asacol safe for patients with mild renal impairment?
  For patients with an eGFR ≥ 60 mL/min/1.73 m², standard dosing is generally safe. Those with eGFR < 60 mL/min require dose reduction and periodic monitoring of renal function to detect early signs of nephrotoxicity.

• Can Asacol be combined with biologic therapy for ulcerative colitis?
  Yes, many clinicians use mesalamine as adjunct maintenance therapy alongside biologics such as infliximab or adalimumab. This combination may help sustain remission while allowing lower biologic dosing, but the regimen should be individualized by a gastroenterologist.

• Does Asacol interact with common herbal supplements like turmeric or ginseng?
  Current evidence does not indicate a direct pharmacokinetic interaction, but both turmeric and ginseng possess anti‑inflammatory properties that could theoretically augment mesalamine effects. Patients should disclose all supplements to their prescriber.

• How long does it take for Asacol to show clinical improvement?
  Symptomatic relief is often observed within 2–4 weeks of consistent use, while endoscopic mucosal healing may require 8–12 weeks. Early response varies with disease severity and adherence to the dosing schedule.

• Can I travel internationally with Asacol prescribed in Hong Kong?
  Yes, but you should carry the original prescription, a copy of the medication label, and a letter from your physician describing the medical necessity. This eases customs clearance and ensures continuity of therapy abroad.

• What is the typical cost of generic mesalamine compared with the Asacol brand?
  Generic mesalamine tablets available through our online pharmacy are usually 30 %–45 % less expensive than the branded Asacol product, while delivering the same therapeutic dose and clinical efficacy.
