Avelox (Moxifloxacin Hydrochloride) - Summary



Fluoroquinolones, including AVELOX®, are associated with an increased risk of tendinitis and tendon rupture in all ages. This risk is further increased in older patients usually over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart or lung transplants [see Warnings and Precautions ( 5.1 )].

Fluoroquinolones, including AVELOX, may exacerbate muscle weakness in persons with myasthenia gravis. Avoid AVELOX in patients with known history of myasthenia gravis [see Warnings and Precautions].



AVELOX (moxifloxacin hydrochloride) is a synthetic broad spectrum antibacterial agent for oral and intravenous administration. Moxifloxacin, a fluoroquinolone, is available as the monohydrochloride salt of 1-cyclopropyl-7-[(S,S)-2,8-diazabicyclo[4.3. 0]non-8-yl]-6-fluoro-8-methoxy-1,4-dihydro-4-oxo-3 quinoline carboxylic acid.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of AVELOX and other antibacterial drugs, AVELOX 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.

AVELOX   Tablets and IV are indicated for the treatment of adults (≥ 18 years of age) with infections caused by susceptible strains of the designated microorganisms in the conditions listed below [see Dosage and Administration and Use In Specific Populations ].

Culture and Susceptibility Testing

Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify organisms causing infection and to determine their susceptibility to moxifloxacin [see Clinical Pharmacology]. Therapy with AVELOX may be initiated before results of these tests are known; once results become available, appropriate therapy should be continued.

Acute Bacterial Sinusitis

AVELOX is indicated for the treatment of Acute Bacterial Sinusitis caused by Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis [see Clinical Studies ].

Acute Bacterial Exacerbation of Chronic Bronchitis

AVELOX is indicated for the treatment of Acute Bacterial Exacerbation of Chronic Bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae, methicillin-susceptible Staphylococcus aureus, or Moraxella catarrhalis [see Clinical Studies].

Community Acquired Pneumonia

AVELOX is indicated for the treatment of Community Acquired Pneumonia caused by Streptococcus pneumoniae (including multi-drug resistant strains*), Haemophilus influenzae, Moraxella catarrhalis, methicillin-susceptible Staphylococcus aureus, Klebsiella pneumoniae, Mycoplasma pneumoniae, or Chlamydophila pneumoniae.

* MDRSP, Multi-drug resistant Streptococcus pneumoniae includes isolates previously known as PRSP (Penicillin-resistant S. pneumoniae), and are strains resistant to two or more of the following antibiotics: penicillin (minimum inhibitory concentrations [MIC] ≥ 2 mcg/mL), 2nd generation cephalosporins (for example, cefuroxime), macrolides, tetracyclines, and trimethoprim/sulfamethoxazole [see Clinical Studies ].

Uncomplicated Skin and Skin Structure Infections

AVELOX is indicated for the treatment of Uncomplicated Skin and Skin Structure Infections caused by methicillin-susceptible Staphylococcus aureus or Streptococcus pyogenes [see Clinical Studies].

Complicated Skin and Skin Structure Infections

AVELOX is indicated for the treatment of Complicated Skin and Skin Structure Infections caused by methicillin-susceptible Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, or Enterobacter cloacae [see Clinical Studies ].

Complicated Intra-Abdominal Infections

AVELOX is indicated for the treatment of Complicated Intra-Abdominal Infections including polymicrobial infections such as abscess caused by Escherichia coli, Bacteroides fragilis, Streptococcus anginosus, Streptococcus constellatus, Enterococcus faecalis, Proteus mirabilis, Clostridium perfringens, Bacteroides thetaiotaomicron, or Peptostreptococcus species [see Clinical Studies].

Antibiotic therapy for complicated intra-abdominal infections (cIAIs) should provide broad-spectrum coverage both Gram-positive and Gram-negative microorganisms... The results show that moxifloxacin is a valuable treatment option for a range of community-acquired cIAIs with mild-to-moderate severity.

OBJECTIVES: (i) the inflammatory response to CPB may be different from that of infectious disease states that were used to establish the immunomodulatory effects of moxifloxacin; and (ii) a single intravenous dose, which was used in this investigation, may not lead to high enough plasma and intracellular concentrations..

Clinical Trials Related to Avelox (Moxifloxacin)

Food and Insulin Effect on QT/QTC Interval of ECG [Completed]
Moxifloxacin is routinely used as a probe to confirm assay sensitivity in thorough electrocardiogram (ECG) studies. It has been shown that a meal shortens the QT interval, which may affect pharmacokinetics (PK) and/or pharmacodynamics (PD) of the study drug. However, there is no published data clarifying this issue. There is also a paucity of data investigating ethnic differences of the effects of medicines on QTc. The aims of the study were to compare the effect of different food contents to placebo on the changes in ECG and to demonstrate the effect of insulin, C-peptide and glucose on the ECG. This was done by giving different treatments on separate days, which included intravenous insulin, a high carbohydrate breakfast [>70%], and a calorie reduced low carbohydrate American FDA standard breakfast. Moxifloxacin 400 mg was used as a positive control and was given with and without food to Caucasian and Japanese volunteers to investigate racial differences.

Safety, Tolerability and Pharmacokinetics of Single Dose Intravenous Moxifloxacin in Pediatric Patients [Completed]
The purpose of this study is to describe the pharmacokinetics of moxifloxacin in children to see what the best dose should be for children in the future. Pharmacokinetics is to see how the body absorbs, distributes, breaks down and gets rid of the study drug. The pharmacokinetics of certain drugs may be altered in children due to developmental differences in various organ functions responsible for drug elimination, as well as in general distribution characteristics. The safety of moxifloxacin in children with infections will also be looked at. Results from this study will be used to guide dosing strategies of the larger clinical trial planned for children

Moxifloxacin Versus Ceftriaxone in the Treatment of Primary Pyogenic Liver Abscess [Recruiting]
This clinical trial compares the use of moxifloxacin versus ceftriaxone in the treatment of primary pyogenic liver abscess. The trial will include nonpregnant adults presenting with primary liver abscess based on clinical diagnosis and computed tomography. The trial aims to determine whether the use of moxifloxacin can effectively treat primary pyogenic liver abscess and shorten hospitalization. This regimen has the additional benefit of avoiding nephrotoxic agents, such as aminoglycosides, used frequently in treatment of pyogenic liver abscess. Development of antibiotic resistance to colonized bacteria in the gastrointestinal tract will also be evaluated using stool cultures.

QT Intervals Study to Compare the Acute Effects of Orally Inhaled Dihydroergotamine (DHE), Oral Moxifloxacin, and Placebo [Completed]
Compare the acute effect on the QT interval of MAP0004 (Dihydroergotamine Mesylate delivered by Oral Inhalation) with Moxifloxacin and Placebo.

Greatest International Antiinfective Trial With Avelox [Completed]
The observation period for each patient covered an initial treatment period with Avelox® plus optional 2 long-term follow-up periods (6 and 12 months).For each patient, the physician documented data at any initial visit (baseline) and at least one short-term follow-up visit (=initial treatment period).Optionally, long-term follow-ups (6 and 12 months) were documented, and a patient questionnaire was filled in.
