Pharmacology

Eravacycline is a fluorocycline antibiotic within the tetracycline class that binds to the 30S ribosomal subunit and prevents the incorporation of amino acid residues into elongating peptide chains, thereby, inhibiting bacterial protein synthesis.

Half-Life Elimination

20 hours

Protein Binding

79% to 90% (increases with increasing plasma concentrations)

Hypersensitivity to eravacycline, tetracycline-class antibacterial drugs, or any component of the formulation.

Dosing: Adult

Intra-abdominal infections, complicated: IV: 1 mg/kg every 12 hours for 4 to 14 days

Dosage adjustment with concomitant strong CYP3A inducers (eg, rifampin): Increase to 1.5 mg/kg every 12 hours.

Dosing: Geriatric

Refer to adult dosing.

Reconstitution

Reconstitute each vial with 5 mL SWFI. Swirl gently; avoid shaking, which may cause foaming. Do not use if solution is cloudy or has visible particles. Reconstituted solution must be further diluted to allow for IV administration. Transfer full or partial vial contents to an IV bag of NS to a final concentration of 0.3 mg/mL (within a range of 0.2 to 0.6 mg/mL). Do not shake the bag. Reconstituted solution should be clear, yellow to orange color.

Administration

IV: Infuse diluted solution IV over ~60 minutes through dedicated line or via Y-site. If the same IV line is used for sequential infusion of several drugs, flush line with NS before and after eravacycline administration. Do not mix with other drugs or add to solutions containing other drugs.

Storage

Store intact vials in original carton at 2°C to 8°C (36°F to 46°F). Reconstituted and diluted solutions may be stored at room temperature (≤25°C [77°F]) for up to 6 hours or may be stored refrigerated (2°C to 8°C [36°F to 46°F]) for up to 24 hours. Do not freeze.

Drug Interactions

Aminolevulinic Acid (Systemic): Photosensitizing Agents may enhance the photosensitizing effect of Aminolevulinic Acid (Systemic). Avoid combination

Aminolevulinic Acid (Topical): Photosensitizing Agents may enhance the photosensitizing effect of Aminolevulinic Acid (Topical). Monitor therapy

BCG (Intravesical): Antibiotics may diminish the therapeutic effect of BCG (Intravesical). Avoid combination

BCG Vaccine (Immunization): Antibiotics may diminish the therapeutic effect of BCG Vaccine (Immunization). Monitor therapy

Cholera Vaccine: Antibiotics may diminish the therapeutic effect of Cholera Vaccine. Management: Avoid cholera vaccine in patients receiving systemic antibiotics, and within 14 days following the use of oral or parenteral antibiotics. Avoid combination

CYP3A4 Inducers (Strong): May decrease the serum concentration of Eravacycline. Management: Increase the eravacycline dose to 1.5 mg/kg every 12 hours when combined with strong CYP3A4 inducers. Consider therapy modification

Lactobacillus and Estriol: Antibiotics may diminish the therapeutic effect of Lactobacillus and Estriol. Monitor therapy

Mecamylamine: Tetracyclines may enhance the neuromuscular-blocking effect of Mecamylamine. Avoid combination

Methoxyflurane: Tetracyclines may enhance the nephrotoxic effect of Methoxyflurane. Avoid combination

Mipomersen: Tetracyclines may enhance the hepatotoxic effect of Mipomersen. Monitor therapy

Neuromuscular-Blocking Agents: Tetracyclines may enhance the neuromuscular-blocking effect of Neuromuscular-Blocking Agents. Monitor therapy

Penicillins: Tetracyclines may diminish the therapeutic effect of Penicillins. Consider therapy modification

Porfimer: Photosensitizing Agents may enhance the photosensitizing effect of Porfimer. Monitor therapy

Retinoic Acid Derivatives: Tetracyclines may enhance the adverse/toxic effect of Retinoic Acid Derivatives. The development of pseudotumor cerebri is of particular concern. Exceptions: Adapalene; Bexarotene (Topical); Tretinoin (Topical). Avoid combination

Sodium Picosulfate: Antibiotics may diminish the therapeutic effect of Sodium Picosulfate. Management: Consider using an alternative product for bowel cleansing prior to a colonoscopy in patients who have recently used or are concurrently using an antibiotic. Consider therapy modification

Typhoid Vaccine: Antibiotics may diminish the therapeutic effect of Typhoid Vaccine. Only the live attenuated Ty21a strain is affected. Management: Vaccination with live attenuated typhoid vaccine (Ty21a) should be avoided in patients being treated with systemic antibacterial agents. Use of this vaccine should be postponed until at least 3 days after cessation of antibacterial agents. Consider therapy modification

Warnings/Precautions

Concerns related to adverse effects:

• Anaphylactic/Hypersensitivity reactions: Life-threatening (anaphylactic) reactions have been reported; discontinue if an allergic reaction occurs. Avoid use in patients with known hypersensitivity to tetracyclines.

• Antianabolic effects: May be associated with antianabolic effects observed with the tetracycline class (including increased BUN, azotemia, acidosis, and hyperphosphatemia).

• Hepatotoxicity: May be associated with abnormal liver function tests due to structural similarities with tetracyclines; discontinue use when suspected.

• Pancreatitis: May be associated with pancreatitis due to structural similarities with tetracyclines.

• Photosensitivity: May be associated with photosensitivity due to structural similarities with tetracyclines.

• Pseudotumor cerebri: May be associated with pseudotumor cerebri due to structural similarities with tetracyclines.

• Superinfection: Use may result in fungal or bacterial superinfection, including Clostridioides (formerly Clostridium) difficile infection (CDI) and colitis; CDI has been observed >2 months postantibiotic treatment.

Disease-related concerns:

• Hepatic impairment: Use with caution in patients with hepatic impairment; dosage adjustment recommended in severe hepatic impairment.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Special populations:

• Pediatric: May cause permanent tooth discoloration, enamel hypoplasia, or reversible inhibition of bone growth; use should be avoided during tooth and bone development (children <8 years of age).

Other warnings/precautions:

• Limitations of use: Not indicated for the treatment of complicated urinary tract infection in adults; eravacycline failed to demonstrate efficacy in 2 randomized, double-blind, active-controlled clinical trials.

Monitoring Parameters

Monitor hepatic function periodically. Observe for signs and symptoms of anaphylaxis during administration.

Pregnancy Considerations

Tetracyclines cross the placenta.

As a class, tetracyclines accumulate in developing teeth and long tubular bones (Mylonas 2011). Exposure during the second and third trimesters of pregnancy may cause reversible inhibition of bone growth. Permanent discoloration of teeth (yellow, gray, brown) can occur following in utero exposure and is more likely to occur following long-term or repeated exposure.

Patient Education

• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)

• Patient may experience nausea, vomiting, injection site irritation, or diarrhea. Have patient report immediately to prescriber signs of liver problems (dark urine, fatigue, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or jaundice), signs of acidosis (confusion, fast breathing, tachycardia, abnormal heartbeat, severe abdominal pain, nausea, vomiting, fatigue, shortness of breath, or loss of strength and energy), signs of pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), headache, vision changes, change in amount of urine passed, urinary retention, or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (HCAHPS).

• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
