Embodiment 1

[0032] Prescription: (by weight percentage)

[0033] Levofloxacin hydrochloride 54%, starch 36%, micronized silica gel 9%, magnesium stearate 1%.

[0034] Preparation:

[0035] 1) The raw and auxiliary materials are passed through a 100-mesh sieve for later use;

[0036] 2) The raw and auxiliary materials are dry mixed evenly, and the mixing time is not less than 0.5 hours;

[0037] 3) Calculate the loading amount after the content detection, and fill the capsules.

Embodiment 2

[0039] Prescription: (by weight percentage)

[0040] Levofloxacin hydrochloride 60%, starch 20%, sodium carboxymethyl starch 9%, micronized silica gel 9%, magnesium stearate 2%.

[0041] Preparation:

[0042] 1) The raw and auxiliary materials are passed through a 100-mesh sieve for later use;

[0043] 2) The raw and auxiliary materials are dry mixed evenly, and the mixing time is not less than 0.5 hours;

[0044] 3) Calculate the loading amount after the content detection, and fill the capsules.

[0045] Taking Zhuhai United Laboratories Levofloxacin Hydrochloride Capsules (0.1g) as the reference preparation, the sample of Levofloxacin Hydrochloride Capsules in Example 1 was used for relative bioavailability test to determine whether it is bioequivalent to the reference preparation with the same dosage. Methods: A two-period randomized cross-over experimental design was used. Eighteen healthy male volunteers were randomly divided into two groups. After the volunteers to...

Abstract

The invention provides a levofloxacin hydrochloride capsule and a preparation method thereof. The levofloxacin hydrochloride capsule is characterized by being prepared from the following ingredients in percentage by the medicine composition recipe weight: 20 to 70 percent of levofloxacin hydrochloride, 20 to 65 percent of filling agents and disintegrating agents and 1 to 15 percent of lubricating agents. The levofloxacin hydrochloride capsule and the preparation method have the advantages that the recipe matching is reasonable; the preparation method is simple; the operation is easy; the production requirements can be met by conventional equipment; and the levofloxacin hydrochloride capsule and the preparation method are suitable for industrial mass production.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and in particular relates to a levofloxacin hydrochloride capsule and a preparation method thereof. Background technique [0002] Levofloxacin is the levoisomer of ofloxacin, a fluoroquinolone. It was first successfully developed by Japan's Daiichi Pharmaceutical Co., Ltd. in 1994 and launched in Japan, and was allowed to enter China in 1995. [0003] Levofloxacin appears to be the levorotatory optical isomer of ofloxacin, which is a racemic mixture of the levorotatory and dextrorotatory isomers. Since the antibacterial activity of the left-handed isomer is 8-128 times stronger than that of the right-handed isomer, the antibacterial activity of levofloxacin is 2 times stronger than that of ofloxacin, and the clinical dosage is 1 / 2 of ofloxacin. Levofloxacin not only has strong antibacterial activity against Gram-positive and Gram-negative clinical common pathogens, but also has strong...
