[The clinico-immunological evaluation of the ribomunyl treatment of chronic bronchitis patients].

The paper reports the results of ribomunil trial in chronic bronchitis (CB) patients who suffered from frequent exacerbations. The drug was found to act primarily on a phagocytic component of the immunity and local immunity of the respiratory mucosa. Because of its vaccine-like effect, ribomunil administration is most beneficial in CB remission. Ribomunil treatment results in reduction of the number and duration of CB exacerbations, of the scope of antibacterial therapy.
