Dirithromycin or Dynabec is an macrolide antibiotic similar to erythromycin used to treat infections - bronchitis, pneumonia, soft tissue, skin infections. It is as effective as erythromycin.
Dirithromycin or Dynabec interferes with bacterial genetic material making it impossible for the bacteria to reproduce. It has no effect on human cells.
Dirithromycin or Dynabec has gastro intestinal side effects similar to other erythromycins - nausea, abdominal pain.
Dirithromycin or Dynabec's absorption is slightly enhanced by food and thus people can take it with a meal. It is a longer acting antibiotic and thus it can be taken once or twice daily. These two characteristics mean that people find it convenient to take. >People with a sensitivity to erythromycin will also be sensitive to Dirithromycin or Dynabec. People with sensitive stomachs may not be able to tolerate Dirithromycin or Dynabec.
As with all other erythromycins, Dirithromycin or Dynabec will interact with some of the non sedation antihistamines - terfenadine, astemizole - to cause heart beat irregularities.
