Overview

How to Use This Medicine

Proper Use of This Medication

To use this medication correctly, follow your doctor's instructions and read all the information provided. This medication is designed for rectal use only and should not be taken by mouth. You may be prescribed both an oral tablet or capsule and a rectal product to use simultaneously.

Continue using this medication as directed by your doctor or healthcare provider, even if you start feeling better. It is recommended to use this medication at bedtime. Before using, make sure you understand the proper administration technique. If you have any questions or concerns, consult your doctor or pharmacist.

Administration Instructions

Shake the suspension well before use to ensure the medication is evenly mixed.
Retain the suspension in your rectum for as long as possible to allow for optimal absorption.
Note that the enema may darken slightly over time after the foil pouch is opened. It can still be used if the color change is minimal. However, if the enema turns dark brown, do not use it. If you are unsure about the suitability of the enema, consult your doctor or pharmacist.

Storage and Disposal

Store this medication at room temperature.
Keep the rectal suspension in its foil packaging until you are ready to use it. Do not refrigerate the suspension.
Protect the rectal suspension from heat sources to maintain its potency.

Missed Dose

If you miss a dose, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and resume your regular dosing schedule. Do not take two doses at the same time or take extra doses to compensate for the missed dose.
💡

Lifestyle & Tips

  • Follow your doctor's dietary recommendations for ulcerative colitis.
  • Maintain good hydration.
  • Avoid known triggers for your colitis symptoms.
  • Administer the enema at bedtime, if possible, to allow the medication to remain in the rectum for several hours.

Dose Adjustments

Renal Impairment:

Mild: Use with caution; monitor renal function.
Moderate: Use with caution; monitor renal function. Consider dose reduction or alternative therapy.
Severe: Contraindicated or not recommended due to increased risk of renal toxicity.
Dialysis: Not recommended. Mesalamine and its metabolites are dialyzable, but risk of toxicity outweighs benefits in severe renal impairment.

Hepatic Impairment:

Mild: Use with caution; monitor liver function.
Moderate: Use with caution; monitor liver function. Consider dose reduction or alternative therapy.
Severe: Use with caution; monitor liver function. Not recommended in severe hepatic impairment.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Mesalamine is an aminosalicylate that exerts its anti-inflammatory action locally in the colon. Its exact mechanism is not fully understood but is thought to involve inhibition of prostaglandin and leukotriene synthesis (via inhibition of cyclooxygenase and lipoxygenase pathways), scavenging of free radicals, and inhibition of neutrophil chemotaxis and adhesion. It may also modulate immune cell function and cytokine production.
📊

Pharmacokinetics

Absorption:

Bioavailability: Approximately 10-30% (systemic absorption from rectal administration is low, primarily local action)
Tmax: Not applicable for local action; systemic Tmax is variable (e.g., 4-12 hours for oral forms, but rectal absorption is minimal)
FoodEffect: Not applicable for rectal enema.

Distribution:

Vd: Not available (systemic distribution is limited due to low absorption)
ProteinBinding: Approximately 43% for mesalamine, 78% for N-acetyl-5-aminosalicylic acid (N-Ac-5-ASA)
CnssPenetration: Limited

Elimination:

HalfLife: Systemic half-life of mesalamine is 0.5-1.5 hours; N-Ac-5-ASA is 5-10 hours (after oral administration, rectal absorption is lower).
Clearance: Not available
ExcretionRoute: Primarily renal excretion of N-Ac-5-ASA and unabsorbed mesalamine in feces.
Unchanged: Less than 10% systemically absorbed mesalamine is excreted unchanged in urine.
âąī¸

Pharmacodynamics

OnsetOfAction: Within days to weeks (clinical improvement typically seen within 3-21 days)
PeakEffect: Within 3-6 weeks of continuous use
DurationOfAction: Maintained with daily administration
Confidence: Medium

Monitoring

đŸ”Ŧ

Baseline Monitoring

Renal function (serum creatinine, BUN)

Rationale: To establish baseline and identify pre-existing renal impairment, as mesalamine can cause nephrotoxicity.

Timing: Prior to initiation of therapy.

Liver function tests (ALT, AST, bilirubin)

Rationale: To establish baseline and identify pre-existing hepatic impairment, as mesalamine can cause hepatotoxicity.

Timing: Prior to initiation of therapy.

Complete Blood Count (CBC) with differential

Rationale: To establish baseline and monitor for blood dyscrasias, especially if co-administered with thiopurines.

Timing: Prior to initiation of therapy.

📊

Routine Monitoring

Renal function (serum creatinine, BUN)

Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)

Target: Within normal limits for age and sex

Action Threshold: Significant increase in creatinine or BUN; consider dose adjustment or discontinuation.

Liver function tests (ALT, AST, bilirubin)

Frequency: Periodically (e.g., every 3-6 months or as clinically indicated)

Target: Within normal limits

Action Threshold: Significant elevation; consider discontinuation.

Complete Blood Count (CBC) with differential

Frequency: Periodically (e.g., every 3-6 months or as clinically indicated), more frequently if co-administered with thiopurines.

Target: Within normal limits

Action Threshold: Significant decrease in cell counts (e.g., leukopenia, thrombocytopenia); investigate and consider discontinuation.

đŸ‘ī¸

Symptom Monitoring

  • Abdominal pain
  • Rectal bleeding
  • Diarrhea
  • Fever
  • Rash
  • Chest pain (pericarditis/myocarditis)
  • Shortness of breath

Special Patient Groups

🤰

Pregnancy

Mesalamine is generally considered safe for use during pregnancy. Studies in animals have not shown harm to the fetus, and human data suggest a low risk. However, it should be used only if clearly needed.

Trimester-Specific Risks:

First Trimester: Low risk; no increased risk of major birth defects observed.
Second Trimester: Low risk.
Third Trimester: Low risk; some reports of renal dysfunction in newborns with prolonged high-dose exposure, but overall risk is low with rectal administration.
🤱

Lactation

Mesalamine and its metabolite are excreted in breast milk in small amounts. While generally considered compatible with breastfeeding, monitor the infant for diarrhea or other adverse effects.

Infant Risk: L2 - Safer. Low risk of adverse effects in breastfed infants due to low systemic absorption and low levels in milk.
đŸ‘ļ

Pediatric Use

Safety and efficacy have not been established in pediatric patients. Use in children should be based on careful consideration of risks and benefits by a specialist.

👴

Geriatric Use

Use with caution in elderly patients, especially those with pre-existing renal or hepatic impairment, due to increased susceptibility to adverse reactions. Monitor renal function closely.

Clinical Information

💎

Clinical Pearls

  • Instruct patients to administer the enema at bedtime and retain it for as long as possible (preferably overnight, 8 hours) to maximize local contact and efficacy.
  • Ensure proper administration technique: shake the bottle well, lie on the left side with the lower leg extended and the upper leg flexed forward, insert the applicator tip gently, and squeeze the bottle slowly.
  • Mesalamine rectal enema is primarily for distal ulcerative colitis (proctitis, proctosigmoiditis) and may not be effective for more extensive disease.
  • Patients should be advised that the enema may stain fabrics.
  • Monitor for signs of mesalamine-induced acute intolerance syndrome (e.g., cramping, acute abdominal pain, bloody diarrhea, fever, headache, rash), which may mimic a flare of inflammatory bowel disease.
🔄

Alternative Therapies

  • Corticosteroid rectal preparations (e.g., hydrocortisone enema, budesonide rectal foam)
  • Oral 5-aminosalicylates (e.g., oral mesalamine, sulfasalazine)
  • Immunomodulators (e.g., azathioprine, mercaptopurine) for more severe or refractory disease
  • Biologic agents (e.g., infliximab, adalimumab) for moderate to severe disease
  • Janus kinase (JAK) inhibitors (e.g., tofacitinib)
