Definitions
- the invention belongs to the field of pharmacy, and relates to a double-release compound preparation which is prepared by preparing brominated dihydroartemisinin into enteric pellets and Fe 2+ agent to prepare gastric-soluble instant-release pellets and then filling the same capsule.
- the formulations of the invention are primarily useful in the treatment of a broad spectrum of cancers.
- bromo-dihydroartemisinin has a more effective anticancer effect than the parent nucleus-artemisinin (see the invention patent entitled 'Certification No.: CN100480250C Chinese Patent No.: CN200610144186.3').
- the mechanism of action is due to the large amount of Fe 2+ required to replicate DNA when cancer cells divide, so the Fe 2+ content of cancer cells is much higher than that of normal cells.
- the artemisinin molecule of bromodihydroartemisinin has a unique internal oxygen bridge structure. After contact with Fe 2+ , the internal oxygen bridge breaks to produce a charged atom called 'free radical'. It will attack the cell membrane, causing the cancer cells to swell or apoptotic.
- the Fe 2+ and oxygen bridge groups are inseparable in anti-cancer function.
- it has a good anti-cancer effect, and it is preferable to use Fe 2+ agent and Bromo-dihydroartemisinin is made into a compound preparation.
- the Fe 2+ agent and the brominated dihydroartemisinin directly hit the surface (reacting) in the stomach, which is very likely to cause damage to the stomach wall cells.
- a compound double release capsule preparation consisting of brominated dihydroartemisinin and a Fe 2+ agent.
- the Fe 2+ agent it is absorbed in the stomach under the condition of gastric acid, and the bromo-dihydroartemisinin is absorbed in the jejunum.
- the brominated dihydroartemisinin is coated and enteric coated, and the iron is Ordinary stomach-soluble pellets.
- Bromo-dihydroartemisinin is a sustained-release, iron-based immediate release, which can eliminate the side effects of stomach injury by separating the two components in time and at the tissue site.
- a compound double-release capsule preparation consisting of brominated dihydroartemisinin and Fe 2+ agent, including enteric pellets and gastric-soluble instant-release pellets, enteric solution
- the pellets are made of brominated dihydroartemisinin and a pharmaceutically acceptable excipient, and then coated with an enteric coating;
- the Fe 2+ agent is pharmaceutically acceptable
- the agent is made into gastric-soluble instant-release pellets, and then the brominated dihydroartemisinin enteric-coated pellets and the Fe 2+ gastric-coated instant-release pellets are placed in a common stomach-soluble capsule shell to prepare a compound double-release capsule preparation.
- the content of brominated dihydroartemisinin in the compound double-release capsule preparation is 15-20%
- the content of Fe 2+ is 1.5-2.0%
- the balance is excipient.
- the Fe 2+ agent may be ferrous sulfate, ferrous lactate or ferrous succinate, and we prefer ferrous sulfate (FeSO 4 ⁇ 7H 2 O) in terms of mass percent in terms of brominated dihydroartemisinin.
- ferrous sulfate FeSO 4 ⁇ 7H 2 O
- the content of brominated dihydroartemisinin is 15-20%
- the content of ferrous sulfate is 7.5-10%
- the balance is excipient.
- the invention provides a pellet core and a coating formula of the brominated dihydroartemisinin enteric pellets: the pellet core of the brominated dihydroartemisinin enteric pellets is composed of brominated dihydroartemisinin and lactose, starch, Magnesium stearate is prepared according to the conventional pellet pellet preparation method. Enteric coating of brominated dihydroartemisinin enteric pellets from enteric acrylic acid, ethylene phthalate, Tween -80, castor oil, made of 80% ethanol. Finally, the brominated dihydroartemisinin enteric pellets were prepared by coating according to the conventional pellet method.
- the enteric coating of the above-mentioned brominated dihydroartemisinin enteric pellets is also suitable as a coating of a sustained release pellet by a commercially available enteric coating.
- the present invention further provides a pellet core formulation gastric immediate-release pellets of Fe 2+ agent, pellet cores gastric immediate-release pellets of the Fe 2+ Fe 2+ agent agent with lactose, dextrin, and 10% PVP in ethanol was press
- the existing pellets are prepared by a pellet core preparation method. The prepared pellets are quickly dissolved in the stomach.
- the Fe 2+ agent gastric-soluble immediate release pellets may be subjected to gastric coating or non-coating treatment as needed.
- the above two kinds of pellets may be provided with different color coats to distinguish or not include color coats, but the pile ratio is consistent. They are then dry blended at the respective clinically desired levels and filled with capsules. The clinical application of this dosage form is suitable for a broad spectrum of cancer medications.
- METHODS Liver cancer MHCC97 cells in logarithmic growth phase were inoculated into a 96-well plate cell culture plate by routine digestion and then adjusted to 8 ⁇ 10 3 suspension. After culturing for 24 hours, the culture solution was aspirated, and ferrous sulfate and bromodihydroartemisinin (Br-DHA) were mixed with the cell culture solution at a certain ratio and then added. A blank control well and a Br-DHA control well were set and cultured in the incubator for 3 days. The cell count results of the conventional method are shown in Table 1.
- the invention has the beneficial effects that the invention realizes that the patient can simultaneously take the brominated dihydroartemisinin enteric pellets and the Fe 2+ gastric dissolving immediate release pellets in the same capsule preparation, which is convenient to take and brominated dihydrogen Artemisinin enteric-coated pellets and Fe 2+ gastric-coated instant-release pellets are encapsulated, and Fe 2+ gastric-soluble immediate-release pellets are absorbed in the stomach under gastric acid conditions, and brominated dihydroartemisinin The dissolved pellets are absorbed in the jejunum, which avoids the effects of brominated dihydroartemisinin and Fe 2+ in the stomach and damages the cells in the stomach wall.
- the brominated dihydroartemisinin is a sustained release
- the Fe 2+ agent is an immediate release
- the side effects of the stomach can be avoided by separating the two components in time and at the tissue site.
