What enzymes are affected by rifampin?
Drug metabolizing enzymes and transporters affected by rifampin include cytochromes P450 (CYP) 1A2, 2B6, 2C8, 2C9, 2C19, and 3A4, UDP-glucuronyltransferases (UGT), sulfotransferases, carboxylesterases, and transporters including P-glycoprotein (P-gp) and multidrug resistance-associated protein 2 (MRP2). Most drugs are substrates for one or more of these enzyme or transporter pathways and these pathways may be induced by rifampin simultaneously. Therefore, rifampin may increase the metabolism and decrease the activity of certain coadministered drugs or increase the activity of a coadministered pro-drug (where metabolic activation is required) and has the potential to perpetuate clinically important drug drug interactions against many drugs and across many drug classes (Table 1).

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]
