- the film-forming polymer used in the present invention allows the immediate release of vitamin D, this is due to the fact that the polymer is easily soluble in the conditions of the gastrointestinal tract.
- the film-forming polymer used belongs to the class of cellulose derivatives, methacrylates, polysaccharides, phthalates and polyvinyl alcohol.
- the polymer used is a polymer selected from cellulose derivatives, methacrylates and polyvinyl alcohol, guar gum, or a combination thereof.
- the polymer is hydroxypropylmethylcellulose or polyvinyl alcohol.
- the vitamin D suspended in the polymer is selected from vitamin D2 and D3, or a combination thereof.

- the composition stands out for its have two distinct mechanisms of vitamin D release: a first of immediate release, provided by the external coating; and a second extended release, provided by the extended release matrix.
- This combination of profiles allows for an immediate peak of vitamin D release, with the objective of obtaining adequate concentrations for calcium absorption, followed by the controlled release of vitamin D, with the objective of maintaining the said adequate concentration for calcium absorption throughout the life. time.
- the matrix of the composition allows the prolonged release of calcium, in such a way that the composition presents the profile of calcium release, which is highlighted by the increasing curve of calcium release over time, as exemplified in Figure 1.
- the vitamin D release profiles and the calcium salt release profile are synergistic against calcium absorption, as they allow calcium to be much more efficiently absorbed throughout its release, which reduces the amount of calcium. unabsorbed calcium, which would be eliminated in the faeces.
- composition is presented in the form of tablets.
- composition is presented in the form of mini-tablets, which have a diameter of from about 0.5 mm to about 7 mm.
- the set of two or more mini-tablets can be termed as "multi-particulate” and can be understood as a dosage form in which the therapeutic amounts of the active components, in this case, preferably, calcium salt and vitamin D, are divided into several mini pills.
- the active components in this case, preferably, calcium salt and vitamin D
- composition when presented in the form of mini-tablets, presents an easy administration by the oral route, since the small size of the mini-tablets greatly facilitates their swallowing, presenting itself as a more comfortable alternative for calcium ingestion in therapeutically acceptable doses.
- mini-tablets when administered have improved distribution in the gastrointestinal system, since the subdivisions of the doses of calcium therapeutically accepted into small subunits, which are exactly the mini-tablets, promotes a better spread of said dose through the gastrointestinal system. Furthermore, its prolonged release, promoted by the matrix, allows the amount of calcium not to be released abruptly.
- the division of doses into subunits and the slow release promoted by the matrix prevent an immediate release of the total dose, which is more comfortable for the patient, reducing the feeling of heaviness in the stomach, characteristic of the ingestion of large amounts of calcium.
- the present invention therefore, also relates to a method for treating or preventing conditions related to low intake and/or increased calcium requirement, comprising administering at least one oral dosage form of said calcium and vitamin D composition.
- the method of treating or preventing may involve administering more than one dosage form, i.e., administering more than one of the minitablets of the present invention.
- the amount of mini-tablet to be used will depend on the desired amount of calcium and vitamin D that the patient/consumer consumes.
- This dosage type refers to a multiparticulate dosage form.
- the method may only involve the administration of a single dosage form, i.e., a tablet or mini-tablet, when it is already in sufficient amount of calcium and vitamin D to meet the desired therapeutic effect.
- the composition of the present invention can be used for the preparation of a medicament or supplements for treating or preventing conditions related to low concentrations of calcium in bones and blood.
- the supplement or drug must be able to store the solid composition in the preferred form of mini-tablets in a container such as, for example, sachets, vials, vials and boxes.
- the containers are sachets, due to their practicality.
- the container must contain a sufficient amount of mini-tablets to achieve the therapeutic amount of vitamin D and calcium salt.
- the present invention can also be used as a method to treat or prevent conditions related to low calcium intake and/or increased calcium requirement, such as, for example, osteoporosis.
- the granulation was carried out by applying the excipients: 10% microcrystalline cellulose (PH101) and 10% gellan gum LA, as shown in Table 1.
