The film-coat inactive ingredients are hypromellose, titanium dioxide (E 171), polyethylene glycol, talc, and iron oxide red (E 172). The film-coat for the 24 mg of sacubitril and 26 mg of valsartan tablet and the 97 mg of sacubitril and 103 mg of valsartan tablet also contains iron oxide black (E 172). The film-coat for the 49 mg of sacubitril and 51 mg of valsartan tablet contains iron oxide yellow (E 172). chem structure

The active ingredient in sevelamer carbonate tablets is sevelamer carbonate, a polymeric amine that binds phosphate and is meant for oral administration. It was developed as a pharmaceutical alternative to sevelamer hydrochloride (Renagel ® ). Sevelamer carbonate is an anion exchange resin, with the same polymeric structure as sevelamer hydrochloride, in which carbonate replaces chloride as the counterion. While the counterions differ for the two salts, the polymer itself, the active moiety involved in phosphate-binding, is the same. Sevelamer carbonate tablets are known chemically as poly(allylamine-co-N,N′-diallyl-1,3-diamino-2-hydroxypropane) carbonate salt. Sevelamer carbonate is hygroscopic, but insoluble in water. The structure is represented in Figure 1 . Figure 1. Chemical Structure of Sevelamer Carbonate Sevelamer Carbonate Tablets: Each film-coated tablet of sevelamer carbonate tablets contains 800 mg of sevelamer carbonate on an anhydrous basis. The inactive ingredients are carnauba wax, hypromellose, hydroxypropyl cellulose, microcrystalline cellulose, polyethylene glycol, sodium chloride, titanium dioxide, and zinc stearate. The tablet imprint contains black iron oxide, propylene glycol and hypromellose. Figure 1

Silodosin is a selective antagonist of alpha-1 adrenoreceptors. The chemical name of silodosin is 1-(3-Hydroxypropyl)-5-[(2 R )-2-({2-[2-(2,2,2­- trifluoroethoxy)phenoxy]ethyl}amino)propyl]-2,3-dihydro-1 H -indole-7-carboxamide and the molecular formula is C 25 H 32 F 3 N 3 O 4 with a molecular weight of 495.53. The structural formula of silodosin is: Silodosin is a white to pale yellowish white powder that melts at approximately 105° to 109°C. It is very soluble in acetic acid, freely soluble in alcohol, and very slightly soluble in water. Each silodosin capsules, 4 mg and 8 mg for oral administration contains 4 mg or 8 mg silodosin respectively and inactive ingredients: gelatin, mannitol, pregelatinized starch [Botanical source: corn (maize)], sodium lauryl sulphate, sodium stearyl fumarate and titanium dioxide. Each capsule of 4 mg and 8 mg are imprinted with gold pharmaceutical ink or green pharmaceutical ink respectively and contains: FD & C blue #2 aluminum lake (green pharmaceutical ink), butyl alcohol, dehydrated alcohol, isopropyl alcohol, propylene glycol, shellac, strong ammonia solution, titanium dioxide (green pharmaceutical ink), and yellow iron oxide. structure
