[Bivalent-vegetative long-term therapy with glauko biciron (author's transl)]

Long-term therapy using a combination of Pilocarpine and Phenylephrine in three different concentrations is described. The trial was carried out in the form of a multi-center study by general practitioners and showed the constant effect over lengthy periods of time, with no signs of tachyphylaxis or an increase in effect, which would have pointed to an increase in the effective level. The number of side-effects is minimal, due to the submaximal doses used.
