Solution Reconstituted, Intravenous [preservative free]:
Tygacil: 50 mg (1 ea) [contains lactose]
Generic: 50 mg (1 ea)
Brand Names: U.S.
- Antibiotic, Glycylcycline
A glycylcycline antibiotic that binds to the 30S ribosomal subunit of susceptible bacteria, thereby, inhibiting protein synthesis. Generally considered bacteriostatic; however, bactericidal activity has been demonstrated against isolates of S. pneumoniae and L. pneumophila. Tigecycline is a derivative of minocycline (9-t-butylglycylamido minocycline), and while not classified as a tetracycline, it may share some class-associated adverse effects. Tigecycline has demonstrated activity against a variety of gram-positive and -negative bacterial pathogens including methicillin-resistant staphylococci.

Hypersensitivity to tigecycline or any component of the formulation
Documentation of allergenic cross-reactivity for tetracyclines is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Canadian labeling: Additional contraindications (not in U.S. labeling): Hypersensitivity to tetracycline class of antibiotics

Add 5.3 mL NS, D5W, or LR to each 50 mg vial. Swirl gently to dissolve. Resulting solution is 10 mg/mL. Reconstituted solution must be further diluted to allow IV administration. Transfer to 100 mL IV bag for infusion (final concentration should not exceed 1 mg/mL). Reconstituted solution should be yellow-orange; discard if not this color.
IV: Infuse over 30 to 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, D5W, or LR before and after tigecycline administration.
Store intact vials at 20°C to 25°C (68°F to 77°F); excursions are permitted between 15°C and 30°C (59°F and 86°F).

ALERT: U.S. Boxed WarningMortality:
An increase in all-cause mortality has been observed in a meta-analysis of phase 3 and 4 clinical trials in tigecycline-treated patients versus comparator. The cause of this mortality risk difference of 0.6% (95% confidence interval [CI], 0.1 to 1.2) has not been established. Tigecycline should be reserved for use in situations when alternative treatments are not suitable.
Concerns related to adverse effects:
• Anaphylactic/Hypersensitivity reactions: May cause life-threatening anaphylaxis. Due to structural similarity with tetracyclines, avoid use in patients with known hypersensitivity to tetracycline-class antibiotics.
• Antianabolic effects: May be associated with antianabolic effects observed with the tetracycline class (including increased BUN, azotemia, acidosis, and hyperphosphatemia).
• Coagulopathy: May be associated with abnormalities of blood coagulation parameters, including prolongation of PT and aPTT and decreased fibrinogen that may be dose- and/or time-dependent, in particular in patients with renal and hepatic impairment; discontinue use when suspected (Cui 2019).
• Hepatotoxicity: Abnormal liver function tests (increased total bilirubin, prothrombin time, transaminases) have been reported. Isolated cases of significant hepatic dysfunction and hepatic failure have occurred. Closely monitor for worsening hepatic function in patients who develop abnormal liver function tests during therapy. Adverse hepatic effects may occur after drug discontinuation.
• Pancreatitis: Acute pancreatitis (including fatalities) has been reported, including patients without known risk factors; discontinue use when suspected.
• 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: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Treatment-related mortality: [US Boxed Warning]: In a meta analysis of Phase 3 and 4 clinical trials, an increase in all-cause mortality has been observed in tigecycline-treated patients versus comparator-treated patients. The cause of the mortality risk difference (0.6% [95% CI 0.1, 1.2]) has not been established. Use should be reserved for situations in which alternative treatments are not suitable. In general, deaths were the result of worsening infection, complications of infection, or underlying comorbidity.
• Hepatic impairment: Use with caution in patients with hepatic impairment; dosage adjustment recommended in severe hepatic impairment.
• Intra-abdominal infections: Avoid use as monotherapy for patients with intestinal perforation (in the small sample of available cases, sepsis/septic shock occurred more frequently than patients treated with imipenem/cilastatin comparator).
• Pediatric: Safety and efficacy in children and adolescents <18 years of age have not been established due to increased mortality observed in trials of adult patients. Use only if no alternative antibiotics are available. Because of effects on tooth development (yellow-gray-brown discoloration), use in patients <8 years of age is not recommended.
• Appropriate use: Do not use for diabetic foot infections; non-inferiority was not demonstrated in studies. Do not use for healthcare-acquired pneumonia (HAP) or ventilator-associated pneumonia (VAP); increased mortality and decreased efficacy have been reported in HAP and VAP trials.
Hepatic function (periodically); coagulation parameters (including aPTT, PTT, fibrinogen) at baseline and regularly during therapy. Observe for signs and symptoms of anaphylaxis during administration.
Tigecycline crosses the placenta.
Tetracyclines accumulate in developing teeth and long tubular bones (Mylonas 2011). Permanent discoloration of teeth (yellow, gray, brown) can occur following in utero exposure and is more likely to occur following long-term use or short-term repeated exposure. In addition, tetracycline use has been associated with reversible retardation of skeletal development and reduced bone growth.
