Tolerability of 3-day, once-daily azithromycin suspension versus standard treatments for community-acquired paediatric infectious diseases.

Tolerability of azithromycin oral suspension, 10 mg/kg once daily for 3 days, was assessed in paediatric patients (< or = 18 years) with respiratory or skin and soft-tissue infections. Of 2425 patients evaluated, 1213 received azithromycin and 1212 received standard regimens of amoxycillin/clavulanic acid, cefaclor, cefixime, ceftriaxone, clarithromycin, erythromycin, or penicillin V. The incidence of treatment-related adverse events was significantly lower in patients receiving azithromycin than comparators (7.9 vs. 11.5%, P=0.003), while discontinuation rates were similar (1.0 and 1.1%, respectively). Significantly fewer gastrointestinal events were recorded for azithromycin than comparators (6.5 vs. 9.9%, P=0.002), and their duration was significantly shorter (mean 2.3 vs. 5.0 days, P=0.0001). Azithromycin paediatric oral suspension is well tolerated and associated with significantly fewer adverse events than comparators.

Azithromycin: a new 15-membered macrolide.

Azithromycin is the sole member of the macrolide sub-class, the azalides. Due to its altered chemical structure, azithromycin is characterized by a broader spectrum of activity, lower incidence of adverse events and drug interactions and a pharmacokinetic profile, that is in contrast to existing macrolides. Because of its high and prolonged cellular and tissue concentrations, patients are able to complete a course of azithromycin within a shorter timeframe as compared to other antibiotics. Azithromycin is widely used in the treatment of adult and pediatric respiratory tract infections. Continued research into azithromycin's utility has resulted in indication development for several devastating infections such as trachoma. Large-scale studies of its activity against Chlamydia pneumoniae related atherosclerosis are underway.

Paediatric safety of azithromycin: worldwide experience.

Adverse events and laboratory abnormalities were monitored over 35 days after the commencement of treatment in 45 open studies conducted in Europe, South America, Africa and Asia. These studies were to assess the clinical efficacies of azithromycin and comparator antimicrobial agents in the treatment of paediatric acute bacterial infections. Children (6 months-16 years of age) had been treated with an oral suspension of azithromycin (10 mg/kg given once daily for 3 consecutive days) or with the approved oral dosing regimen of the comparator (amoxycillin, co-amoxiclav, cefixime, cefaclor, clarithromycin, erythromycin, penicillin V, cloxacillin, or roxithromycin). Adverse events were recorded in 232/2655 (8.7%) children treated with azithromycin and in 180/1844 (9.8%) who received comparator treatment. The majority of the treatment-related adverse events were classed as being of only mild or moderate severity and were gastrointestinal: 140 (5.3%) in azithromycin- and 120 (6.5%) in comparator-treated children. Co-amoxiclav was responsible for proportionately more of such events than any other agent. Treatment was discontinued prematurely due to an adverse event in 34 (1.3%) azithromycin- and in 31 (1.7%) comparator-treated children. Incidences of clinically significant laboratory abnormalities were low and occurred with comparable frequency in both treatment groups. The present analysis confirms that azithromycin can be safely used to treat bacterial infections in children of all ages.

Clinical safety of intravenous amrinone--a review.

Clinical trials of intravenous amrinone were performed in 462 patients severely ill with congestive heart failure. All were monitored invasively. Adverse reactions were complicated by underlying disease severity and concomitant drug therapy. No consistent pattern of arrhythmias emerged in relation to intravenous amrinone administration. Thrombocytopenia was noted in 2.4% of patients, but it was asymptomatic with no demonstrable bone marrow depression or antiplatelet antibodies. Gastrointestinal adverse effects, hypotension and fever were rare, each occurring in fewer than 2% of patients. Liver enzyme alterations were seen in 1 patient, but it could not be determined whether these changes were related to intravenous use of the drug. Chest pain and irritation at the site of injection were noted in 1 patient each. Spontaneous anecdotal postapproval reports cited tachycardia, liver enzyme elevation, thrombocytopenia, intravenous site irritation, failure to respond and anaphylactoid response as adverse effects or possible adverse effects; each was mentioned in 3 or fewer reports. Drugs contraindicated for concomitant use with intravenous amrinone are listed, and chemical interactions with glucose solutions and intravenous furosemide are discussed.
