What is Linezonix?
Linezonix (Linezonix) is an antibiotic that fights bacteria in the body. Linezonix is also an MAO (monoamine oxidase) inhibitor.
Linezonix is used to treat different types of bacterial infections, such as pneumonia, skin infections, and infections that are resistant to other antibiotics.
Linezonix may also be used for purposes not listed in this medication guide.
Linezonix indications
Linezonix Tablets are indicated for the treatment of infections caused by susceptible strains of the designated microorganisms in the specific conditions listed below. Linezonix Tablets are not indicated for the treatment of Gram-negative infections. It is critical that specific Gram-negative therapy be initiated immediately if a concomitant Gram-negative pathogen is documented or suspected.
Pneumonia
Nosocomial pneumonia caused by Staphylococcus aureus (methicillin-susceptible and -resistant isolates) or Streptococcus pneumoniae.
Community-acquired pneumonia caused by Streptococcus pneumoniae, including cases with concurrent bacteremia, or Staphylococcus aureus (methicillin-susceptible isolates only).
1.2 Skin and Skin Structure Infections
Complicated skin and skin structure infections, including diabetic foot infections, without concomitant osteomyelitis, caused by Staphylococcus aureus (methicillin-susceptible and -resistant isolates), Streptococcus pyogenes, or Streptococcus agalactiae. Linezonix Tablets have not been studied in the treatment of decubitus ulcers.
Uncomplicated skin and skin structure infections caused by Staphylococcus aureus (methicillin-susceptible isolates only) or Streptococcus pyogenes.
Vancomycin-resistant Enterococcus faecium Infections
Vancomycin-resistant Enterococcus faecium infections, including cases with concurrent bacteremia.
1.4 Usage
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Linezonix Tablets and other antibacterial drugs, Linezonix Tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
The safety and efficacy of Linezonix Tablets given for longer than 28 days have not been evaluated in controlled clinical trials.
How should I use Linezonix?
Use Linezonix suspension as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Linezonix suspension by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
- Gently mix before each dose by turning the bottle upside-down 3 to 5 times. Do not shake Linezonix suspension.
- Use a measuring device marked for medicine dosing. Ask your pharmacist for help if you are unsure of how to measure your dose.
- To clear up your infection completely, take Linezonix suspension for the full course of treatment. Keep taking it even if you feel better in a few days.
- If you miss a dose of Linezonix suspension, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Linezonix suspension.
Uses of Linezonix in details
Linezonix is used to treat bacterial infections such as pneumonia (community acquired pneumonia and nosocomial pneumonia), skin infections and infections that are resistant to other antibiotics.
Linezonix description
Linezonix I.V. Injection, Linezonix Tablets, and Linezonix for
Oral Suspension contain Linezonix, which is a synthetic antibacterial agent of the oxazolidinone class.
Linezonix Tablet for oral administration contains 600 mg Linezonix as a film-coated compressed tablet. The sodium (Na+) content is 2.92 mg per 600-mg tablet (0.1 mEq/tablet).
Linezonix for
Oral Suspension is supplied as an orange-flavored granule/powder for constitution into a suspension for oral administration. Following constitution, each 5 mL contains 100 mg of Linezonix. The sodium (Na+) content is 8.52 mg/5 mL (0.4 mEq/5 mL).
Linezonix I.V. Injection is supplied as a ready-to-use sterile isotonic solution for intravenous infusion. Each mL contains 2 mg of Linezonix. The sodium (Na+) content is 0.38 mg/mL (5 mEq/300-mL bag; 3.3 mEq/200-mL bag; and 1.7 mEq/100-mL bag).
The chemical name for Linezonix is (S)-N-[[3-[3-Fluoro-4-(4-morpholinyl)phenyl]-2-oxo-5-oxazolidinyl] methyl]-acetamide.
The empirical formula is C16H20FN3O4. Its molecular weight is 337.35.
Excipients/Inactive Ingredients: Film-Coated Tablet: Corn starch, microcrystalline cellulose, hydroxypropylcellulose, sodium starch glycolate, magnesium stearate, hypromellose, polyethylene glycol, titanium dioxide, and carnauba wax. Powd forOral Suspension:
Sucrose, citric acid, sodium citrate, microcrystalline cellulose and carboxymethylcellulose sodium, aspartame, xanthan gum, mannitol, sodium benzoate, colloidal silicon dioxide, sodium chloride, and flavors. Infusion: Sodium citrate, citric acid, and dextrose in an aqueous vehicle for intravenous administration.
Linezonix dosage
Patients whose therapy is started with Linezonix injection may be switched to Linezonix tablets or Linezonix for oral suspension, with no dosage adjustment.
Duration of treatment is variable, depending on the pathogen isolated, site of infection and its severity. To date, the maximum duration of treatment has been 28 days.
Pre-term neonates <7 days of age (gestational age <34 weeks) have lower systemic Linezonix clearance values and larger AUC values than many full-term neonates and older infants. By day 7 of age, Linezonix clearance and AUC values are similar to those of full-term neonates and older infants.
Elderly patients: No dose adjustment is required.
Patients with Renal Insufficiency: No dose adjustment is required. Patients with severe renal insufficiency (ie, creatinine clearance <30 mL/min): No dose adjustment is required. Due to the unknown clinical significance of higher exposure (up to 10-fold) to the 2 primary metabolites of Linezonix in patients with severe renal insufficiency, Linezonix should be used with special caution in these patients and only when the anticipated benefit is considered to outweigh the theoretical risk.
As approximately 30% of a Linezonix dose is removed during 3 hrs of hemodialysis, Linezonix should be given after dialysis in patients receiving such treatment. The primary metabolites of Linezonix are removed to some extent by hemodialysis, but the concentrations of these metabolites are still very considerably higher following dialysis than those observed in patients with normal renal function or mild to moderate renal insufficiency.
Therefore, Linezonix should be used with special caution in patients with severe renal insufficiency who are undergoing dialysis and only when the anticipated benefit is considered to outweigh the theoretical risk.
To date, there is no experience of Linezonix administration to patients undergoing continuous ambulatory peritoneal dialysis (CAPD) or alternative treatments for renal failure (other than haemodialysis).
Patients with Hepatic Insufficiency: No dose adjustment is required. However, there are limited clinical data and it is recommended that Linezonix should be used in such patients only when anticipated benefit is considered to outweigh the theoretical risk.
Children: Recommended dosages for pediatric patients, see Table 2.
Linezonix Injection: Administer Linezonix injection by IV infusion over a period of 30-120 min. Do not use the IV infusion bag in series connections. Do not introduce additives into the IV solution. If Linezonix injection is to be given concomitantly with another drug, each drug should be given separately, in accordance with the recommended dosage and route of administration for each product.
Linezonix interactions
See also:
What other drugs will affect Linezonix?
Monoamine Oxidase Inhibition: Linezonix is a reversible, nonselective inhibitor of
monoamine oxidase. Therefore, Linezonix has the potential for interaction with adrenergic
and serotonergic agents.
Adrenergic Agents: Some individuals receiving Linezonix may experience a reversible
enhancement of the pressor response to indirect-acting sympathomimetic agents,
vasopressor or dopaminergic agents. Commonly used drugs such as phenylpropanolamine
and pseudoephedrine have been specifically studied. Initial doses of adrenergic agents, such
as dopamine or epinephrine, should be reduced and titrated to achieve the desired response.
Serotonergic Agents: Co-administration of Linezonix and serotonergic agents was not
associated with serotonin syndrome in Phase 1, 2 or 3 studies. Spontaneous reports of
serotonin syndrome associated with co-administration of Linezonix and serotonergic agents,
including antidepressants such as selective serotonin reuptake inhibitors (SSRIs), have been
reported. Patients who are treated with Linezonix and concomitant serotonergic agents
should be closely observed as described in the PRECAUTIONS, General Section.
Strong CYP450 Inducers: In a study in healthy volunteers, co-administration of rifampin
with oral Linezonix resulted in a 21% decrease in Linezonix Cmax and a 32% decrease in
Linezonix AUC0-12. The clinical significance of this interaction is unknown. Other strong
inducers of hepatic enzymes (e.g. carbamazepine, phenytoin, phenobarbital) could cause a
similar or smaller decrease in Linezonix exposure.
Linezonix side effects

What are the possible side effects of Linezonix?
Adult Patients: The safety of Linezonix formulations was evaluated in 2046 adult patients enrolled in 7 phase III comparator-controlled clinical trials who were treated for up to 28 days. In these studies, 85% of the adverse events reported with Linezonix were described as mild to moderate in intensity. Table 14 shows the incidence of adverse events reported in at least 2% of patients in these trials. The most common adverse events in patients treated with Linezonix were diarrhea (incidence across studies: 2.8-11%), headache (incidence across studies: 0.5-11.3%) and nausea (incidence across studies: 3.4-9.6%).
Other adverse events reported in phase II and phase III studies included oral moniliasis, vaginal moniliasis, hypertension, dyspepsia, localized abdominal pain, pruritus and tongue discoloration.
Table 15 shows the incidence of drug-related adverse events reported in at least 1% of adult patients in these trials by dose of Linezonix.
Pediatric Patients: The safety of Linezonix formulations was evaluated in 215 pediatric patients ranging in age from birth through 11 years and in 248 pediatric patients 5-17 years (146 of these 248 were 5-11 years and 102 were 12-17 years). These patients were enrolled in 2 phase III comparator-controlled clinical trials and were treated for up to 28 days. In these studies, 83% and 99%, respectively, of the adverse events reported with Linezonix were described as mild to moderate in intensity. In the study of hospitalized pediatric patients (birth through 11 years) with gram-positive infections who were randomized 2:1 (Linezonix:vancomycin), mortality was 6% (13/215) in the Linezonix arm and 3% (3/101) in the vancomycin arm. However, given the severe underlying illness in the patient population, no causality could be established. Table 16 shows the incidence of adverse events reported in at least 2% of pediatric patients treated with Linezonix in these trials.
Table 17 shows the incidence of drug-related adverse events reported in >1% of pediatric patients (and >1 patient) in either treatment group in the comparator-controlled phase III trials.
Laboratory Changes: Linezonix has been associated with thrombocytopenia when used in doses up to and including 600 mg every 12 hrs for up to 28 days. In phase III comparator-controlled trials, the percentage of adult patients who developed a substantially low platelet count (defined as <75% of lower limit of normal and/or baseline) was 2.4% (range among studies: 0.3-10%) with Linezonix and 1.5% (range among studies: 0.4-7%) with a comparator. In a study of hospitalized pediatric patients ranging in age from birth through 11 years, the percentage of patients who developed a substantially low platelet count (defined as <75% of lower limit of normal and/or baseline) was 12.9% with Linezonix and 13.4% with vancomycin. In an outpatient study of pediatric patients from 5-17 years, the percentage of patients who developed a substantially low platelet count was 0% with Linezonix and 0.4% with cefadroxil. Thrombocytopenia associated with the use of Linezonix appears to be dependent on duration of therapy (generally >2 weeks of treatment). The platelet counts for most patients returned to the normal range/baseline during the follow-up period. No related clinical adverse events were identified in phase III clinical trials in patients developing thrombocytopenia. Bleeding events were identified in thrombocytopenic patients in a compassionate use program for Linezonix; the role of Linezonix in these events cannot be determined.
Changes seen in other laboratory parameters, without regard to drug relationship, revealed no substantial differences between Linezonix and the comparators. These changes were generally not clinically significant, did not lead to discontinuation of therapy and were reversible. The incidence of adults and pediatric patients with at least 1 substantially abnormal hematologic or serum chemistry value is presented in Tables 18, 19, 20 and 21.
Post-Marketing Experience: Myelosuppression (including anemia, leukopenia, pancytopenia, and thrombocytopenia) has been reported during post-marketing use of Linezonix. Peripheral neuropathy and optic neuropathy sometimes progressing to loss of vision, have been reported in patients treated with Linezonix. Lactic acidosis has been reported with the use of Linezonix. Although these reports have primarily been in patients treated for longer than the maximum recommended duration of 28 days, these events have also been reported in patients receiving shorter courses of therapy. Serotonin syndrome has been reported in patients receiving concomitant serotonergic agents, including antidepressants eg, selective serotonin reuptake inhibitors (SSRIs) and Linezonix. Convulsions have been reported with the use of Linezonix. Superficial tooth discoloration and tongue discoloration have been reported with the use of Linezonix. The tooth discoloration was removable with professional dental cleaning (manual descaling) in case with known outcome. Anaphylaxis, angioedema and bullous skin disorders such as those described as Stevens-Johnson syndrome have been reported. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to Linezonix or a combination of these factors. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made and causal relationship cannot be precisely established.

What is the most important information I should know about Linezonix?
Do not use Linezonix if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam, Zelapar), or tranylcypromine (Parnate) in the last 14 days. A dangerous drug interaction could occur, leading to serious side effects.
Many drugs can interact with Linezonix. Before using Linezonix, tell your doctor about all other medications you use. You may need to stop using certain medicines before using Linezonix (in some cases for up to 5 weeks before you start Linezonix). During your treatment with Linezonix, do not start or stop using any other medications unless your doctor tells you to.
You should not use Linezonix if you have untreated or uncontrolled high blood pressure, a carcinoid tumor, adrenal gland tumor, or a severely overactive thyroid.
If you take an antidepressant or psychiatric medication, call your doctor right away if you have signs of a serious drug interaction, including: confusion, memory problems, feeling hyperactive (mentally or physically), loss of coordination, muscle twitching, shivering, sweating, diarrhea, and/or fever.
Eating tyramine while you are using Linezonix can raise your blood pressure to dangerous levels. Avoid foods that have a high level of tyramine, such as aged cheeses or meats, pickled or fermented meats, smoked or air-dried meats, sauerkraut, soy sauce, tap beer, red wine, or any meat, cheese, or other protein-based food that has been improperly stored.
