 Background: The current Integrated management of childhood infections IMCI algorithm prescribes that children with wheeze and fast breathing presenting to first level health facilities are given antibiotics if they continue to have fast breathing after two doses of bronchodilator. The primary purpose of the algorithm is to prevent mortality due to bacterial pneumonia. However, an unknown proportion of children managed in this fashion will have a viral related wheezing illness or asthma rather than pneumonia. Although it is unlikely that wheezing syndromes are a significant cause of mortality for children in developing countries, these algorithms are likely to result in unnecessary administration of antibiotics as well as inadequate treatment of recurrent wheezing illness. We do not have clear evidence about whether antibiotics can be withheld in some categories of children with wheeze. It is clear that wheeze can occur in bacterial infection and in addition co-infection with virus and bacteria has been well demonstrated in several studies of pneumonia etiology in children. Although some studies have found that children with more severe disease or who are blood culture positive are more likely to be febrile at presentation, this sign is not sufficiently sensitive or specific to determine whether antibiotics should be administeredSetting: The study will be conducted in eight medical colleges situated in Lucknow, Nagpur, New Delhi, Mumbai, Chennai, Trivandrum, Vellore, and Chandigarh. Design: This will be a multicentric, randomized, double blind efficacy trial. . Hypothesis: The primary hypothesis is that the use of oral amoxycillin for three days would be as effective, in terms of clinical cure on day 4 as compared to use of oral placeboMain objective: To compare the proportion of children aged 2 to 59 months presenting with non-severe pneumonia with wheeze whose respiratory rate does not fall below the age specific cut-off after three doses of nebulized salbutamol, that achieve clinical cure on day 4 on 3 day of treatment with oral amoxycillin versus placebo.Inclusion criteria: Children aged 2-59 months with non-severe pneumonia based on WHO criteria of respiratory rate above the age specific cut-off, audible ausculatory wheeze. Exclusion criteria: Children with severe disease, received any documented antibiotic treatment in the past 48 hours, diagnosed asthmatic on maintenance therapy, complicating acute non-pulmonary or chronic illness, known drug allergy, hospitalization in the past 2 weeks, history of measles within the last month, known immunodeficiency disorder, prior enrollment in the study, residing in areas not accessible for follow-up or whose guardian refuses to consent for the study. Sample size: Has been calculated to test the null hypothesis. There will be 950 children in each arm. Thus each site is required to recruit a minimum of 225 cases over 18 months.
