The present invention describes the use of pyrazole or indazole derivates as activators of soluble guanylate cyclase. Some compounds disclosed are novel. All activators are vasodilators and/or inhibit platelet aggregation and are therefore useful in the treatment of peripheral vascular diseases such as hypertension, angina pectoris or atherosclerosis, or in the treatment of prevention of glaucoma, preeclampsia, Raynaud's syndrome, stroke or erectile disfunctions.

The invention relates to new 3-pyridyl-5-alkoxy-pyrazole derivatives of the following formula: ##STR1## wherein R.sub.1 represents a 4-pyridyl, 3-pyridyl or 2-pyridyl group which is unsubstituted or which may be substituted with one or two lower alkyl groups; R.sub.2 represents a hydrogen atom or a lower alkyl group; and R.sub.3 represents a lower alkyl group, a phenyl group or an aralkyl group; and the acid addition salts thereof. The derivatives may be prepared by alkylation of a 3-pyridyl-5-pyrazolone. The derivatives are medicinally useful, particularly for the treatment of cardiac deficiency.
