It’s not uncommon for people to get pneumonia after taking antibiotics.
But new research shows that it can be treated with a second antibiotic.
The discovery could also help improve treatment of other pneumonia-related conditions, including heartburn.
A team of researchers led by Dr. Steven T. Whelan, a professor of infectious disease at the Johns Hopkins University School of Medicine, published a study in the American Journal of Tropical Medicine and Hygiene.
The study involved 10 people with a history of pneumonia, which they all had had previously treated with antibiotics.
All the people were given two doses of a new medication, which is called a single-dose regimen.
The team studied the effectiveness of the medication against bacteria that can cause pneumonia in both healthy and severely ill people.
They looked at the efficacy against bacteria commonly found in the lungs of healthy people, as well as bacteria commonly associated with pneumonia in patients with pneumonia, including Escherichia coli and Pseudomonas aeruginosa.
A single-dose regimen used in the study was shown to be as effective as the two-dose combination used in most other studies.
In all 10 people, the drug seemed to work as well against the bacterial strains that are common in the lung, the authors said.
But when the team looked at people with pneumonia that were severely ill, the new medication showed an 85 percent reduction in the number of organisms that were found in that person’s lungs.
The findings suggest that the drug could be used to treat patients who have not had pneumonia before.
The drug has been used successfully in people with severe lung infections for more than a decade.
The current study was conducted in the first phase of a larger clinical trial, and it will be followed by larger trials to see if the drug is safe and effective in people of all ages and conditions.
