Beclometasone Powder for Inhalation, Metered-dose Powder Inhaler<\/p>\n
Action and use<\/strong><\/p>\n Glucocorticoid.<\/p>\n Beclometasone Inhalation Powder consists of Beclometasone Dipropionate or Beclometasone Dipropionate Monohydrate in microfine powder or aerodynamically equivalent, either alone or combined with a suitable carrier. It is administered by a dry-powder inhaler.<\/p>\n The inhalation powder complies with the requirements stated under Preparations for Inhalation and with the following requirements.<\/p>\n The size of aerosol particles to be inhaled is controlled so that a consistent portion is deposited in the lungs. The fine-particle characteristics of preparations for inhalation are determined using the method described in Appendix XII C7. Preparations for inhalation: Aerodynamic Assessment of Fine Particles. The test and limits should be agreed with the competent authority.<\/p>\n The water content is controlled to ensure the performance of the product as justified and authorised by the competent authority.<\/p>\n Content of beclometasone dipropionate, C28<\/sub>H37<\/sub>ClO7<\/sub><\/strong><\/p>\n 80.0 to 120.0% of the stated amount.<\/p>\n A. In the Assay, the principal peak in the chromatogram obtained with solution (1) has the same retention time as the principal peak in the chromatogram obtained with solution (2).<\/p>\n B. For products containing lactose; disperse 0.25 g of the inhalation powder in 5 mL of water. Add 5 mL of 6M ammonia and heat in a water-bath at 80\u00b0 for 10 minutes. An orange-red colour is produced.<\/p>\n Complies with the requirements stated under Inhalation Powders using the following method of analysis. Carry out the method for liquid chromatography, Appendix III D, using the following solutions.<\/p>\n (1) Collect single doses of the preparation being examined using the procedure described under Inhalation Powders, Uniformity of delivered dose and dissolve the collected dose in sufficient of a mixture of 45 volumes of water and 55 volumes of acetonitrile to produce a solution containing the equivalent of 0.00005% w\/v of beclometasone dipropionate.<\/p>\n (2) Dilute 10 mL of a solution containing 0.0005% w\/v of beclometasone dipropionate BPCRS in methanol to 100 mL with a mixture of 45 volumes of water and 55 volumes of acetonitrile.<\/p>\n (a) Use a stainless steel column (25 cm \u00d7 4.6 mm) packed with base-deactivated end-capped octylsilyl silica gel for chromatography (5 \u03bcm) (Lichrospher 60 RP-select B is suitable).<\/p>\n (b) Use isocratic elution and the mobile phase described below.<\/p>\n (c) Use a flow rate of 1.3 mL per minute.<\/p>\n (d) Use an ambient column temperature.<\/p>\n (e) Use a detection wavelength of 240 nm.<\/p>\n (f) Inject 100 \u03bcL of each solution.<\/p>\n 25 volumes of water and 75 volumes of methanol.<\/p>\n Calculate the amount of beclometasone dipropionate, C28<\/sub>H37<\/sub>ClO7<\/sub>, per delivered dose using the declared content of C28<\/sub>H37<\/sub>ClO7 <\/sub>in beclometasone dipropionate BPCRS. Repeat the procedure as described for reservoir systems under Inhalation Powders, Uniformity of delivered dose.<\/p>\n Carry out the method for liquid chromatography, Appendix III D, using the following solutions.<\/p>\n (1) Dissolve a quantity of the inhalation powder containing the equivalent of 1.2 mg of beclometasone dipropionate in the mobile phase and dilute to 5 mL with the mobile phase.<\/p>\n (2) Dilute 1 volume of solution (1) to 100 volumes with the mobile phase.<\/p>\n (3) 0.0040% w\/v each of beclometasone 17-propionate BPCRS and beclometasone 21-propionate BPCRS in the mobile phase.<\/p>\n (4) Dilute 1 volume of solution (2) to 20 volumes with the mobile phase.<\/p>\n (a) Use a stainless steel column (25 cm \u00d7 4.6 mm) packed with octadecylsilyl silica gel for chromatography (5 \u03bcm) (Lichrosorb RP18 or Lichrospher RP18 is suitable).<\/p>\n (b) Use isocratic elution and the mobile phase described below.<\/p>\n (c) Use a flow rate of 1 mL per minute.<\/p>\n (d) Use an ambient column temperature.<\/p>\n (e) Use a detection wavelength of 254 nm.<\/p>\n (f) Inject 100 \u03bcL of each solution.<\/p>\n (g) For solutions (1) and (2) allow the chromatography to proceed for twice the retention time of the principal peak.<\/p>\n Dilute 60 volumes of acetonitrile to 100 volumes with water.<\/p>\n When the chromatograms are recorded under the prescribed conditions, the retention time for beclometasone 17-propionate is about 6 minutes, for beclometasone 21-propionate, about 7 minutes and for beclometasone dipropionate, about 13 minutes.<\/p>\n The test is not valid unless, in the chromatogram obtained with solution (3), the resolution between the peaks due to beclometasone 17-propionate and beclometasone 21-propionate is at least 1.4. If necessary adjust the concentration of acetonitrile in the mobile phase.<\/p>\n In the chromatogram obtained with solution (1):<\/p>\n the area of any secondary peak is not greater than twice the area of the principal peak in the chromatogram obtained with solution (2) (2%);<\/p>\n not more than one such peak has an area greater than the area of the principal peak in the chromatogram obtained with solution (2) (1%);<\/p>\n the sum of the areas of all the secondary peaks is not greater than 2.5 times the area of the principal peak in the chromatogram obtained with solution (2) (2.5%).<\/p>\n Disregard any peak with an area less than the area of the principal peak in the chromatogram obtained with solution (4) (0.05%).<\/p>\n Use the average of the individual results determined in the test for Uniformity of delivered dose.<\/p>\n The quantity of active ingredient is stated in terms of the equivalent amount of beclometasone dipropionate.<\/p>\n","protected":false},"excerpt":{"rendered":" (Ph.
