Disease context

glaucoma

Carbonic anhydrase 1 shows approved-linked disease relevance led by glaucoma. 5 more disease programs remain visible in the same review block. 4 linked drugs keep the rationale reviewable. 5 additional disease programs remain visible in the same card. Linked drugs include ACETAZOLAMIDE, ACETAZOLAMIDE SODIUM, DICHLORPHENAMIDE.

Start review with glaucoma because it currently carries approved-linked support. Linked drugs include ACETAZOLAMIDE, ACETAZOLAMIDE SODIUM, DICHLORPHENAMIDE, METHAZOLAMIDE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
