Diagnosis

The patient was diagnosed with an anal fissure and hemorrhoids.

Therapy Details

The patient was started on intravenous ibuprofen (IVIB) to control pain.

  • Dose: 400 mg/100 mL IV
  • Frequency: Twice daily
  • Duration: 8 hourly for two days

Outcome of Therapy

  • Clinical response: Initial improvement was observed upon initiation of IVIB, following which a complete resolution of pain was seen within 16 hours.
  • Time for onset pain relief was around 20 minutes after administration.
  • Reduction in pain and symptomatic relief was observed within 30-45 minutes.
  • The pain did not increase after the first dose.
  • No other intervention was required for pain relief.
  • The patient also experienced lesser pain while defecating.

    Side Effects

  • No side effects were experienced during the treatment.

Discussion

Doctors’ Opinion

  1. “Usually, patients need both intramuscular diclofenac and intravenous paracetamol for pain control and control of fever during the peri-operative period, which is quite cumbersome for patients as they do not want to be pricked routinely, especially on the buttocks.”
  2. “Moreover, choosing ibuprofen is cost-effective for patients.”

Ibuprofen, a nonselective NSAID, can be administrated orally, topically, and parenterally. Ibuprofen can reduce fever, pain, and inflammation related to illness or injury. It acts by inhibiting the COX enzymes, thereby inhibiting the synthesis of prostaglandins. Intravenous ibuprofen (IVIB) was approved in 2009 by the United States Food and Drug Administration (US FDA) for pain management and for alleviating fever in adults. In clinical practice, IVIB can be used for multimodal pain management. Recent studies have shown the benefits of IVIB as a preventive analgesic agent in reducing both pain scores and opioid consumption.2–4

In India, it is approved by Indian regulatory for the short-term symptomatic treatment of fever, when administration by the intravenous route is clinically justified when other routes of administration are not possible and for the short-term symptomatic treatment of acute moderate pain.

Several clinical pieces of evidence have established the benefits and safety profile of IVIB. Published randomized controlled studies have proven the opioid-sparing and analgesic effects of 400 mg and 800 mg doses of IVIB in postoperative patient populations. Improvement in fever curves with IVIB in critically ill and burn patients has also been reported.1

In a narrative review conducted by Southworth et al., 2020, 344 adult patients and healthy volunteers were studied from 9 clinical trials. Among them, 200 patients received IVIB, while the remaining received placebo or comparator medication. It was observed that IVIB resulted in twice the level of plasma ibuprofen compared to oral ibuprofen. It also decreased perioperative pain, improved recovery, reduced the dependency on opioids and over-the–counter medications, and alleviated post-surgical fatigue and stress response. The authors also suggested that the favorable safety profile of IVIB makes it a suitable choice for the management of pre- and postoperative pain.5

A clinical study was conducted by Tomic et al., 2022, to evaluate the analgesic effect of IVIB compared to diclofenac plus orphenadrine in postoperative pain management in patients undergoing orthognathic surgery. Results revealed that ibuprofen administration and lower body mass index (BMI) were associated with less pain for patients who underwent bimaxillary osteotomy on the third postoperative day.2 Singhla et al., 2010, demonstrated that pre- and postoperative administration of IVIB significantly reduced both pain and morphine use in patients undergoing selective orthopedic surgery.6

Zhou et al., 2023, in their recent review, also observed that IVIB did not increase the risk of serious adverse events (AEs) in terms of fever and pain management. There was also a decreased risk of nausea and vomiting. The rapid infusion of IVIB also provided additional benefits during perioperative periods and in emergencies.4

Concluding Remarks

KOL Speaks

“Using intravenous ibuprofen in a 400 mg/ 100-ml dose is advised for effective and safe pain relief. This method provides faster, well-tolerated and longer-lasting pain relief, reduces the frequency of pain relapses, and lessens the need for other pain medications. Additionally, it improves patient compliance by reducing the frequency of dosing and is cost-effective.”
