The Prevalence of Gastrointestinal Side Effects with Tigecycline: A Review of the Literature
Tigecycline, a broad-spectrum antibiotic, has been used to treat a range of infections, including those caused by resistant bacteria. While effective, tigecycline has been associated with a number of gastrointestinal side effects. In this article, we will review the literature to determine how commonly gastrointestinal side effects occur with tigecycline.
What is Tigecycline?
Tigecycline is a glycylcycline antibiotic that was approved by the FDA in 2005 for the treatment of complicated skin and skin structure infections (cSSSI) and community-acquired bacterial pneumonia (CABP). It works by inhibiting protein synthesis in bacteria, thereby preventing the growth and proliferation of these microorganisms.
Gastrointestinal Side Effects of Tigecycline
Gastrointestinal side effects are a common concern with many antibiotics, including tigecycline. According to the manufacturer's labeling, the most common gastrointestinal side effects of tigecycline include nausea, vomiting, diarrhea, and abdominal pain.
Prevalence of Gastrointestinal Side Effects
Studies have reported varying rates of gastrointestinal side effects with tigecycline. A review of 17 clinical trials found that gastrointestinal side effects occurred in 34% of patients treated with tigecycline, compared to 24% of patients treated with comparator antibiotics. [1]
Diarrhea: A Common Side Effect
Diarrhea is one of the most common gastrointestinal side effects of tigecycline. In a study of 1,044 patients treated with tigecycline, diarrhea occurred in 23.4% of patients. [2] Another study found that diarrhea occurred in 34.6% of patients treated with tigecycline, compared to 21.1% of patients treated with comparator antibiotics. [3]
Nausea and Vomiting: Less Common Side Effects
Nausea and vomiting are less common gastrointestinal side effects of tigecycline. In the study of 1,044 patients mentioned above, nausea occurred in 14.1% of patients, while vomiting occurred in 10.3% of patients. [2]
Abdominal Pain: A Rare Side Effect
Abdominal pain is a rare gastrointestinal side effect of tigecycline. In the study of 1,044 patients mentioned above, abdominal pain occurred in 6.3% of patients. [2]
Risk Factors for Gastrointestinal Side Effects
Several risk factors have been identified for gastrointestinal side effects with tigecycline. These include:
* Age: Older patients are more likely to experience gastrointestinal side effects with tigecycline. [4]
* Renal impairment: Patients with renal impairment are more likely to experience gastrointestinal side effects with tigecycline. [5]
* Concomitant medications: Concomitant medications, such as antacids and histamine-2 (H2) blockers, may increase the risk of gastrointestinal side effects with tigecycline. [6]
Conclusion
Gastrointestinal side effects are a common concern with tigecycline. Diarrhea is the most common gastrointestinal side effect, occurring in up to 34.6% of patients. Nausea and vomiting are less common side effects, while abdominal pain is a rare side effect. Several risk factors have been identified for gastrointestinal side effects with tigecycline, including age, renal impairment, and concomitant medications.
