LINZESS (linaclotide) is a guanylate cyclase-C (GC-C) agonist. Linaclotide is a 14-amino acid peptide with the following chemical name: L-cysteinyl-L-cysteinyl-L-glutamyl-L-tyrosyl-L-cysteinyl-L-cysteinyl-L-asparaginyl-L-prolyl-L-alanyl-L-cysteinyl-L-threonyl-glycyl-L-cysteinyl-L-tyrosine, cyclic (1-6), (2-10), (5-13)-tris (disulfide). The molecular formula of linaclotide is C 59 H 79 N 15 O 21 S 6 and its molecular weight is 1526.8. The amino acid sequence for linaclotide is shown below: Linaclotide is an amorphous, white to off-white powder. It is slightly soluble in water and aqueous sodium chloride (0.9%). LINZESS contains linaclotide-coated beads in hard gelatin capsules. LINZESS is available as 72 mcg, 145 mcg and 290 mcg capsules for oral administration. The inactive ingredients of LINZESS 72 mcg capsules include: calcium chloride dihydrate, L-histidine, microcrystalline cellulose, polyvinyl alcohol, and talc. The components of the capsule shell include gelatin and titanium dioxide. The inactive ingredients of LINZESS 145 mcg and 290 mcg capsules include: calcium chloride dihydrate, hypromellose, L-leucine, and microcrystalline cellulose. The components of the capsule shell include gelatin and titanium dioxide. LINZESS (linaclotide) is a guanylate cyclase-C (G-CC) agonist.
