宽与窄

药物用量范围的宽与窄，与疗效密切相关，过于狭窄的剂量范围难以涵盖该药物治疗不同疾病的全部有效剂量，会限制临床处方最佳剂量的选择，影响疗效。

The drug dosage threshold is closely related to efficacy , a narrow dose range is difficult to cover all the effective dose of the drug treatment of different diseases , which may limit the choice of the optimal dose of clinical prescription and affect the efficacy .
