The invention belongs to the technical field of pharmaceutical chemistry, and particularly pertains to benzimidazole derivatives, and preparation process and pharmaceutical uses thereof. Benzimidazole derivatives include Ligustrazine and NO donor derivatives. The kind of the compounds can rapidly release Ligustrazine or No in vivo, so that they can produce effective synergetic effects with Azilsartan, to enhance the anti-hypertension effect, and reduce adverse effects, and the released Ligustrazine can produce ideal protection to patients' livers and kidneys, thereby filling blanks in the prior art.
