This activity will highlight the mechanism of action, adverse event profile, and other key factors (e.g., off-label uses, dosing, pharmacodynamics, pharmacokinetics, monitoring, and relevant interactions) pertinent to members of the healthcare team in the management of patients with tuberculosis and related conditions.

Is rifampin a lipid?

Rifampin is a highly lipid-soluble drug and is available in oral or intravenous formulations. When given orally, it is rapidly absorbed and distributed throughout the body. It is excreted equally in bile and urine and has a half-life of 2.5 hours.[11]  When meninges are inflamed, a significant amount of drugs can enter the cerebrospinal fluid, thereby making it useful clinically in the treatment of bacterial meningitis.[12]  It is available for intravenous use in critically ill patients with life-threatening infections caused by gram-positive organisms when oral formulations are not as effective. It does not require dosage adjustments in renal disorders. It is usually avoided in patients with preexisting liver diseases since rifampin is associated with significant hepatotoxicity, but the dose can be adjusted if a potential benefit exists. It can be safely administered during pregnancy and breastfeeding and is not associated with any congenital malformations or neonatal complications. [13][14]  Cases of rifampin-induced esophagitis have also been documented, especially in the elderly population. This is why it is recommended that rifampin is taken with a full glass of water, 1 or 2 hours before meals.  [15] Rifampin is a potent cytochrome P450 enzyme inducer. A careful review of the patient's medications should be performed in order to avoid any dampening effects of concomitant medications taken alongside rifampin.  [16]

Does rifampin cause liver problems?

Since rifampin can cause significant hepatoxicity, baseline liver function tests (LFTs) are recommended before starting the treatment.   When symptoms of hepatotoxicity (nausea, vomiting, abdominal pain, worsening LFTs, pruritus) occur, the dose should be decreased or rifampin should be stopped completely. Serial blood draws to monitor LFTs are recommended in these cases.  With tuberculosis, guidelines establish that rifampin has to be stopped if alanine aminotransferase (ALT) increases three times the upper limit of normal (with hepatitis symptoms like jaundice, abdominal pain, nausea, anorexia) or five times (when asymptomatic).[23]  The drug concentration levels of concomitantly administered medications are to be monitored regularly due to rifampin's ability to induce microsomal enzymes.  [16] Especial consideration in monitoring rifampin has to be made in certain conditions like; diabetes, malabsorption syndromes, HIV, or in the elderly population, due to a higher rate of poor drug absorption, and increased drug interactions caused by decreased metabolism or clearance.  [24]

Is rifampin a hepatotoxic drug?

Its toxicity has been determined as dose-related (hepato-toxic) or due to the duration of treatment (immuno-allergic toxicity).[17]  Dose-related toxic effects start to appear with the ingestion of 9 to 15 g of rifampin.  [25] A wide variety of symptoms can be seen like; metabolic acidosis (nausea, vomiting, abdominal pain, hyperventilation, and fatigue), thrombocytopenia (skin and mucosal bleeding), oliguric renal failure, convulsions, cholestatic jaundice, and red man syndrome (glowing red discoloration of the skin, facial, and periorbital edema). There is no specific antidote for its toxicity, and treatment is mostly supportive, including airway maintenance, antiemetic medications, gastric lavage with activated charcoal, correction of electrolytes and acid-base balances, active diuresis, and in severe cases, dialysis.  [17] [26]

Does rifampin inhibit RNA?

Rifampin produces bactericidal antimicrobial activity by inhibition of DNA-dependent RNA polymerase (RNAP) either by sterically blocking the path of the elongating RNA at the 5′ end or by decreasing the affinity of the RNAP for short RNA transcripts.  It specifically inhibits the microbial RNAP, halting further RNA synthesis.  [6][7][8]Rifampin has no action on the mammalian RNAP enzyme, thereby decreasing the number of potential adverse effects in humans. Elevated levels of bile acids are primarily responsible for the pruritis seen with cholestatic diseases like primary biliary cirrhosis (PBC). The antipruritic effect of rifampin, which has been described to be of most benefit in cholestatic disorders, is mediated by the upregulation of the microsomal enzymes cytochrome P3A (CYP3A), which subsequently induces hydroxylation of bile acids. The hydroxylation of bile acids decreases their ileal reabsorption which further alleviates the pruritic symptoms. [9][10]

Why is rifampin prescribed?

Abstract

Rifampin is a potent antibiotic against staphylococcal implant-associated infections. In the absence of implants, current data suggest against the use of rifampin combinations.

1. Introduction

Rifampin is one of the first-line drugs against tuberculosis. In addition, it has been used against non-mycobacterial microorganisms, mainly staphylococci, for at least 50 years [ 1 ].

2. Short History of Rifampin Use in Patients with Implant-Associated Staphylococcal Infection

In 1982, the use of rifampin in the treatment of non-tuberculous infections has been initially presented in a large symposium, followed by the publication in a supplemental edition of the Reviews of Infectious Diseases, edited by Merle A. Sande [ 9 ].

3. Evidence for the Efficacy of Rifampin in Animal Studies

The first observation of the biofilm activity of rifampin has been made >35 years ago in the guinea pig tissue cage model [ 15 ]. With four doses of rifampin, implant-associated S. aureus infection could be cured in 100% of the tissue cages, if therapy was started up to 12 h after inoculation.

4. Role of Rifampin in Clinical Studies Involving Orthopedic Implant-Associated Infections

Based on the animal data showing an impressive antibiofilm activity of rifampin against staphylococci, we started to treat patients with orthopedic device-related infection (ODRI) with rifampin combination in clinical routine.

5. Critical Appraisal of a Randomized Controlled Trial (RCT) Showing no Effect of Rifampin

The above mentioned RCT compared the outcome of patients with acute staphylococcal PJI treated with prosthesis retention and either monotherapy without rifampin or rifampin combination [ 8 ]. In this multicenter study conducted from 2006 to 2012 in eight centers, 48 patients with acute PJI were included in the final analysis.

6. Conclusions

Taken together, the controversy about the role of rifampin in biofilm infections is not justified. There is abundant data from in-vitro and animal experiments, as well as clinical studies confirming its antibiofilm effect in patients with staphylococcal orthopedic implant-associated infections undergoing DAIR.
