Pharmacologic class: Semisynthetic echinocandin
Therapeutic class: Antifungal
Pregnancy risk category C
Inhibits glucan synthase, an enzyme present in fungal (but not mammalian) cells; this action inhibits formation of 1,3-beta-D-glucan, an essential component of fungal cell wall.
Powder for injection (lyophilized): 50-mg single-use vial
Indications and dosages
➣ Candidemia and other Candida infections (intra-abdominal abscess, peritonitis)
Adults: Single 200-mg loading dose by I.V. infusion on day 1, followed by 100 mg I.V. daily thereafter. Duration depends on clinical response; generally, therapy continues at least 14 days after last positive culture.
➣ Esophageal candidiasis
Adults: Single 100-mg loading dose by I.V. infusion on day 1, followed by 50 mg I.V. daily thereafter. Treatment should continue for at least 14 days, and for at least 7 days after symptoms resolve; duration depends on clinical response. Due to risk of esophageal candidiasis relapse in patients with human immunodeficiency virus, suppressive antifungal therapy may be considered after treatment ends.
• Hypersensitivity to drug, its components, or other echinocandins
Use cautiously in:
• hepatic impairment
• pregnant or breastfeeding patients
• children (safety and efficacy not established).
☞ Don't give by I.V. bolus.
• Reconstitute only with supplied diluent (20% dehydrated alcohol in water for injection).
• Further dilute only with 5% dextrose injection or normal saline solution, to yield infusion solution concentration of 0.5 mg/ml.
• Give by I.V. infusion within 24 hours of reconstitution.
☞ Don't infuse at a rate exceeding 1.1 mg/minute.
• Don't dilute with other solutions or infuse through same I.V. line with other drugs or electrolytes.
CV: hypotension, phlebitis
GI: aggravated dyspepsia, nausea, vomiting
Hematologic: neutropenia, leukopenia
Skin: rash, urticaria, pruritus, flushing
Drug-diagnostic tests. Alanine aminotransferase, aspartate aminotransferase, gamma glutamyltransferase: increased
• If patient has abnormal liver function tests during therapy, monitor for evidence of worsening hepatic function and weigh risks and benefits of continuing therapy.
• Monitor for rash, urticaria, flushing, dyspnea, and hypotension. (However, these are rare when drug is administered slowly.)
☞ Instruct patient to report rash, itching, unusual bruising or bleeding, unusual tiredness, or yellowing of skin or eyes.
• Advise patient to report troublesome side effects such as GI upset.
• As appropriate, review all other significant adverse reactions and interactions, especially those related to the tests mentioned above.

Adverse Reactions/Side Effects
- ↑ liver enzymes
Fluid and Electrolyte
- anaphylaxis (life-threatening)
- infusion reaction
Drug-Drug interactionNone noted.
- Assess infected area and monitor cultures before and periodically during therapy.
- Specimens for culture should be taken before instituting therapy. Therapy may be started before results are obtained.
- Monitor for signs and symptoms of anaphylaxis (rash, urticaria, flushing, pruritus, bronchospasm, dyspnea, hypotension); usually related to histamine release. To decrease risk, do not exceed a rate of infusion of 1.1 mg/minute.
- Lab Test Considerations: May cause ↑ ALT, AST, alkaline phosphatase, and hepatic enzymes.
- May cause hypokalemia.
- May cause neutropenia and leukopenia.
Potential Nursing DiagnosesRisk for infection (Indications)
- pH: 4.5–4.6.
- Intermittent Infusion: Reconstitute each 50 mg vial with 15 mL or the 100 mg vial with 30 mL of Sterile Water for Injection for a concentration of 3.33 mg/mL. May be stored in refrigerator for up to 1 hr. Diluent: Further dilute within 24 hr by transferring contents of reconstituted vial into IV bag of D5W or 0.9% NaCl. For the 50 mg dose, dilute with 85 mL for an infusion volume of 100 mL. For the 100 mg dose, dilute with 170 mL for an infusion volume of 200 mL. For the 200 mg dose, dilute with 340 mL for a total infusion volume of 400 mL.Concentration: Final concentration should not exceed 0.5 mg/mL. Do not administer solutions that are discolored or contain particulate matter. Store reconstituted solution in refrigerator; do not freeze. Administer within 24 hr.
- Rate: Administer at a rate not to exceed 1.1 mg/min (1.4 mL/min or 84 mL/hr).
