Definitions
- the binder may be selected from povidone, copovidone, methylcellulose, hydroxymethylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, hydroxyethylcellulose, gelatin, guar gum, xan gum or mixtures thereof, Povidone is preferred.
- Figure 2 is a schematic diagram showing the mixing of the micronized enticavir and excipients in the present invention.
- a schematic preparation for formulating a pharmaceutical composition containing low dose enticavir into a tablet may comprise the following steps.
- the entecavir used in step (A) can be synthesized or used commercially by conventional manufacturing methods.
- the entecavir may also use a hydrate thereof or a salt thereof.
- Step (B) is a step of preparing a pharmaceutical composition by mixing the micronized enticavir in step (A) with a pharmaceutical additive commonly used.
- the entecavir component is preferably contained at a low dose, so in step (B), the micronized entecavir and pharmaceutical additives are preferably mixed at 0.01 to 10% by weight and 90 to 99.99% by weight, respectively. Do.
- the disintegrant may be selected from crospovidone, croscarmellose sodium, sodium glycolate starch, pregelatinized starch, grain starch or mixtures thereof, with double crospovidone being preferred.
- the dry granulation compression method can be formulated by compressing and crushing the mixture of step (B), so that the manufacturing process can be simplified by eliminating the dissolution step of the main component unlike the wet granulation compression method.
- other therapeutic agents for hepatitis B virus infection are suitable for oral administration, they may be combined with low doses of entercavir in a single tablet or capsule. If other therapeutic agents are not compatible with entecavir, for example when the mode of administration is different or the frequency of administration is different, the other therapeutic agents may be administered separately.
- the amount of other therapeutic agents administered may be that amount conventionally used in a single therapy or a reduced amount as determined by the attending physician. Separate dosage forms can be administered simultaneously or sequentially according to a predetermined schedule.
- oral dosage formulations containing the low dose enticavir of the present invention may be used in the treatment of co-infected patients.
- Co-infected patients are patients infected with other viral or non-viral diseases in addition to hepatitis B.
- such treatment is possible for hepatitis C patients who have been infected with hepatitis C or HIV.
- Such co-infected patients are preferably treated with the low dose entecavir oral formulation of the present invention in combination with other pharmaceutically active agents.
- patients co-infected with hepatitis B and hepatitis C can be treated with oral formulations of the low dose entecavir of the present invention in addition to the therapy of ribavirin and interferon.
- Tablets were prepared in the same manner as in Example 1, except that the entecavir was micronized to 52.89 ⁇ m in the micronization step.
- Tablets were prepared in the same manner as in Example 1, except that the entecavir was micronized to 21.45 ⁇ m in the micronization step.
- FIG. 3 is a graph comparing the PK profiles of Example 1 and Comparative Example 1.
- Example 1 of the present invention was confirmed to show a nearly equivalent PK profile value of Comparative Example 1 prepared by the prior art.
- the oral dosage form of low dose entecavir prepared by the preparation method of the present invention is excellent in content uniformity despite a simple process, and exhibits sufficient pharmacological effect as a therapeutic agent for chronic hepatitis B and is suitable for commercial use.
- Comparative Example 2 prepared by direct compression without micronization is not suitable for commercial use because the difference between the PK profile of Example 1 and Comparative Example 1 is large.
