Patent Claims:	1. A minitablet for oral administration having a core and an outer coating and having a diameter of 1 mm to 4 mm, wherein the core comprises: an amount of sacubitril and valsartan in a 1:1 molar ratio as an active ingredient; and at least one pharmaceutically acceptable excipient, wherein the amount is about 2 mg to about 5 mg, corresponding to a respective combined amount of valsartan (free acid) and sacubitril (free acid) in a 1:1 molar ratio, wherein the outer coating is in a form of a controlled release and/or a protective film-coating, and wherein the film-coating has a basic butylated methacrylate copolymer content of 50% to 70% by weight of the film coating. 2. The minitablet according to claim 1, wherein the core comprises trisodium [3-((1S,3R)-1-biphenyl-4-ylmethyl-3-ethoxycarbonyl-1 -butylcarbamoyl)propionate-(S)-3′-methyl-2′-(pentanoyl{2″-(tetrazol-5-ylate) biphenyl-4′-ylmethyl}amino)butyrate] hemipentahydrate as the active ingredient. 3. The minitablet according to claim 1, wherein the diameter of the minitablet is 1 mm to 3 mm. 4. The minitablet according to claim 1, wherein the minitablet contains 3.125 mg of the active ingredient. 5. The minitablet according to claim 1, wherein the mini-tablet contains about 3 mg to about 4 mg of trisodium [3-((1S,3R)-1-biphenyl-4-ylmethyl-3-ethoxycarbonyl-1 -butylcarbamoyl)propionate-(S)-3′-methyl-2′-(pentanoyl{2″-(tetrazol-5-ylate) biphenyl-4′-ylmethyl}amino)butyrate] hemipentahydrate. 6. The minitablet according to claim 1, wherein the film-coating comprises a basic butylated methacrylate copolymer formed from monomers selected from butyl methacrylate, (2-dimethylaminoethyl)methacrylate, and methyl methacrylate. 7. The minitablet according to claim 6, wherein the basic butylated methacrylate copolymer is a 1:2:1 copolymer formed from butyl methacrylate, (2-dimethylaminoethyl)-methacrylate and methyl methacrylate. 8. The minitablet according to claim 1, wherein the film-coating further comprises sodium lauryl sulphate, stearic acid, and talcum. 9. The minitablet according to claim 1, wherein the film-coating further comprises talcum at a content of 20% to 40% by weight of the film-coating, stearic acid or magnesium stearate at a content of 5% to 10% by weight of the film-coating, and sodium lauryl sulphate at a content of 4% to 8% by weight of the film-coating. 10. The minitablet according to claim 1, wherein a weight of the film-coating is about 4% to about 8% based on a total weight of the minitablet. 11. The minitablet according to claim 1, wherein a content of the active ingredient in the core is 30% to 70% by weight. 12. The minitablet according to claim 1, wherein the at least one pharmaceutically acceptable excipient comprises (i) microcrystalline cellulose, (ii) hydroxypropylcellulose, (iii) magnesium, calcium, or aluminum stearate, (iv) anhydrous colloidal silica (colloidal silicon dioxide), and (v) talc. 13. The minitablet according to claim 12, wherein microcrystalline cellulose is present in an amount of 35% to 45% by weight, hydroxypropylcellulose is present in an amount of 2% to 8% by weight, magnesium stearate is present in an amount of 1.0 to 5.0% by weight, colloidal silicon dioxide is present in an amount of from 1.0% to 2.0% by weight, and talc is present in an amount of from 0.5 to 1.0% by weight, wherein the % by weight refers to the % by weight of the core. 14. A combination of minitablets and a dispenser, wherein the minitablets comprise the minitablet according to claim 1. 15. A capsule containing 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 minitablets, wherein the minitablets comprise the minitablet according to claim 1. 16. A method of treating heart failure in a pediatric patient, comprising administering to the pediatric patient in need of such treatment the minitablet according to claim 1. 17. A method of treating chronic heart failure, hypertension, angina, myocardial infarction, atherosclerosis, diabetic nephropathy, diabetic cardiac myopathy, renal insufficiency, peripheral vascular disease, left ventricular hypertrophy, cognitive dysfunction or stroke in a patient where low and individual dosing is required or who encounter problems with swallowing, comprising administering to the patient the minitablet according to claim 1. 18. The minitablet according to claim 1, wherein the film-coating dissolves only at a pH of 5 or lower.
