Bronchitis, Otitis Media, Pharyngitis, Tonsillitis
Conditions
Brief summary
This study was performed in children with upper respiratory tract infections (acute ear infection, infection of the tonsils or throat, or bacterial inflammation of the bronchi) who needed treatment with an antibiotic (clarithromycin). The study investigated a new technology which delivers the antibiotic in a straw (dose sipping technology, DST) in comparison to a marketed syrup.
Detailed description
The study population were children aged 2-12 years (weight 12-40 kg) suffering from upper respiratory tract infections (acute otitis media, tonsillitis, pharyngitis, or acute bacterial bronchitis) and who needed antibiotic treatment. The study compared treatment satisfaction and treatment adherence of oral clarithromycin DST (125 mg, 187.5 mg, or 250 mg twice daily) with the established oral clarithromycin syrup administered via a graduated syringe (Klacid Syrup Forte®, 250 mg/5mL) at the same fixed daily doses. Fixed doses of 125 mg, 187.5 mg and 250 mg of clarithromycin DST offer the pediatrician the flexibility to treat children of different body weight and age adequately at the recommended daily dose of 15 (12.5-20) mg/kg. All children were treated for 7 to 10 day (14 to 20 doses). Treatment satisfaction by the guardian/caregiver in terms of handling and administration of the clarithromycin DST straw and the comparator clarithromycin syrup, convenience of the administration, acceptance of taste and aftertaste, and treatment satisfaction with respect to future use was evaluated by means of a Parents' Questionnaire once on either Day 3, 4, or 5 and once on either Day 11, 12, 13, or 14. In addition, treatment adherence/willingness of medication intake and the child's health status were assessed. The safety program comprised recording and evaluation of adverse events and countermeasures.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment adherence | Day 11-14 | The child's adherence to the prescribed course of therapy was checked by determining the number of unused straws or the residual volume in the medication bottles, respectively, when unused study medication was returned to the site on Day 11, 12, 13, or 14. A participant was considered to be: * Fully treatment adherent: \>90 % of prescribed doses taken within the prescribed course of therapy. * Partially treatment adherent: 70-90% of prescribed doses taken within the prescribed course of therapy. * Non adherent: Omission of 2 or more consecutive doses or \<70% of prescribed doses taken within the prescribed course of therapy. The percentage of participants in each of the 3 categories was calculated. |
