Widaplik is a fixed dose combination of telmisartan, amlodipine and indapamide. Widaplik contains telmisartan, a non-peptide angiotensin II receptor (type AT1) antagonist. Telmisartan is chemically described as 4'-[(1,4'-dimethyl-2'-propyl [2,6'-bi-1H-benzimidazol]-1'-yl)methyl]-[1,1'-biphenyl]-2-carboxylic acid. Its empirical formula is C 33 H 30 N 4 O 2 , its molecular weight is 514.63, and the structural formula is: Telmisartan is a white to slightly yellowish solid. It is practically insoluble in water, slightly soluble in methanol and soluble in strong base. Widaplik contains the besylate salt of amlodipine, a dihydropyridine calcium-channel blocker. Amlodipine besylate is chemically described as 3-ethyl-5-methyl (±)-2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-1,4-dihydro-6-methyl-3,5-pyridinedicarboxylate, monobenzenesulfonate. Its empirical formula is C 20 H 25 ClN 2 O 5 •C 6 H 6 O 3 S, its molecular weight is 567.1, and the structural formula is: Amlodipine besylate is a white crystalline powder. It is slightly soluble in water and sparingly soluble in ethanol. Widaplik contains indapamide, a thiazide-like diuretic. Indapamide is chemically described as 4-chloro-N-(2-methyl-1-indolinyl)-3-sulfamoylbenzamide. Its empirical formula is C 16 H 16 ClN 3 O 3 S, its molecular weight is 365.84, and the structural formula is: Indapamide is a white to off-white, crystalline powder. It is soluble in ethyl alcohol and practically insoluble in water. Widaplik tablets are formulated in 3 strengths for oral administration 10 mg/1.25 mg/0.625 mg: combination of 10 mg telmisartan, with 1.25 mg amlodipine (equivalent to 1.73 mg amlodipine besylate), with 0.625 mg indapamide 20 mg/2.5 mg/1.25 mg: combination of 20 mg telmisartan, with 2.5 mg amlodipine (equivalent to 3.47 mg amlodipine besylate), with 1.25 mg indapamide 40 mg/5 mg/2.5 mg: combination of 40 mg telmisartan, with 5 mg amlodipine (equivalent to 6.94 mg amlodipine besylate), with 2.5 mg of indapamide Widaplik also contains the following inactive ingredients: croscarmellose sodium, magnesium stearate, mannitol, meglumine, microcrystalline cellulose, polyvinyl pyrrolidone, pregelatinized starch, and sodium hydroxide. Widaplik tablets are hygroscopic and require protection from moisture. Widaplik tablets require protection from light. Telmisartan-structure Amlodipine Structure Indapamide structure
