22204-88-2 - Tramadol hydrochloride sustained-release capsules
Authoritative Data Verified Data
This product contains tramadol hydrochloride (C16H25N02 • HCI) should be 90.0% ~ 110.0% of the label amount.
trait
The contents of this product are white or off-white small pills or tablets.
identification
- take an appropriate amount of the fine powder of the content of this product (about 0.2g of tramadol hydrochloride), add 5ml of water, shake to dissolve tramadol hydrochloride, filter, take 4 drops of the filtrate and put it into a small tube, after evaporating in a water bath at 80°C, 1 drop of the test solution of citric acid acetic anhydride was added, and the mixture was heated in a water bath at 80-90°C for 3-5 minutes to show a purplish red color.
- in the chromatogram recorded under the content determination item, the retention time of the main peak of the test solution should be consistent with the retention time of the main peak of the reference solution.
- the aqueous solution of this product was chloride identification (1) of the reaction (General 0301).
examination
- relevant substances: take an appropriate amount of the contents of this product (about 0.2g of tramadol hydrochloride), weigh it accurately, put it in a 100ml measuring flask, add 35ml of methanol, and dissolve tramadol hydrochloride by ultrasound, add about 40ml of acetic acid-sodium acetate buffer (pH 4.5), mix well, cool, dilute to the scale with acetic acid-sodium acetate buffer (pH 4.5), shake well, filter, take the continued filtrate as the test solution; Take an appropriate amount of the reference substance of impurity I, weigh it precisely, and add the mobile phase to make a solution containing about 0.2m g per 1 ml, as the reference solution; the sample solution (1 ml) and the control solution (3ml) were accurately weighed and placed in the same 100ml measuring flask, diluted to the scale with the mobile phase, and shaken to obtain a control solution. According to the method of tramadol hydrochloride related substances. If there is a chromatographic peak consistent with the retention time of impurity I in the chromatogram of the test solution, the peak area shall be calculated according to the external standard method. 3%, the peak area of other single impurities shall not be greater than 0.5 times (0.5%) of the peak area of Tramadol in the control solution, and the sum of the peak areas of other impurities shall not be greater than the peak area of Tramadol in the control solution (1.0%).
- the dissolution of this product, according to the dissolution and release determination method (General rule 0931 The first method), with water as the dissolution medium, the speed of 100 rpm, according to the law. At 1 hour, 2 hours, 4 hours and 8 hours, 10ml of the solution was filtered, and the same volume and temperature of water were immediately added, and the filtrate was taken, according to UV-visible spectrophotometry (General rule 0401), determine absorbance at 271nm wavelength; Take appropriate amount of tramadol hydrochloride reference substance, water was added to dissolve and diluted to prepare a solution containing about 80ug per 1 ml, and the same method was used to calculate the dissolution amount of each particle at different times. The dissolution amount of each capsule in 1 hour, 2 hours, 4 hours and 8 hours should be 20% ~ 45%, 35% ~ 60%, 55% ~ 80% and 75% of the label amount respectively, all shall be in accordance with the provisions.
- others should comply with the relevant provisions under the capsule (General 0103).
Content determination
- measured by high performance liquid chromatography (General 0512).
- chromatographic conditions and system suitability test using eighteen alkyl silane bonded silica as filler; Acetic acid-sodium acetate buffer (pH 4.5)-methanol (65:35) as mobile phase; the detection wavelength was 271nm. The number of theoretical plates shall not be less than 1500 based on Tramadol peak.
- the content under the item of difference in loading amount was weighed appropriately (about 50mg equivalent to tramadol hydrochloride), placed in a 100ml measuring flask, and 35ml methanol was added, followed by dissolving tramadol hydrochloride by ultrasound, add acetic acid-sodium acetate buffer (pH 4.5) about 40ml, shake, cool, dilute to the scale with acetic acid-sodium acetate buffer (pH 4.5), shake, filter, the continued filtrate was taken as the test solution, and 20u1 was accurately weighed and injected into the human liquid chromatograph to record the chromatogram, the mobile phase was added to dissolve and diluted to make a solution containing 0.5mg per 1 ml, which was determined by the same method. According to the external standard method to calculate the peak area, that is.
