A comparison of the toxic and allergic reactions occurring with streptomycin and streptoduocin in the treatment of pulmonary tuberculosis.

The investigation took place during two consecutive years. All patients entering hospital during the first year were given streptomycin sulphate and those admitted to hospital during the second year were treated with streptoduocin. All patients who completed three months' treatment with either preparation, or in whom treatment had to be stopped because of a reaction, were included in the series.
