Determination of Paracetamol and Tramadol Hydrochloride in Pharmaceutical Preparations Using Green UV Method

Abstract

A simple, precise, and friendly environmental method for the determination of paracetamol and tramadol hydrochloride in pharmaceutical preparations has been worked out. The method is based on the determination of paracetamol at 242 nm and replaces its concentration in a multicomponent system equation for determination of both paracetamol and tramadol at 227 nm. Beer's law for paracetamol was obeyed over the concentration range 8-25 ppm at 242 nm and 4-16 ppm at 227 nm ,for tramadol it is obeyed over the range 2-14 ppm at 227 nm, water is used as a solvent for dissolution. The method is applicable to the determination of paracetamol and tramadol in their pharmaceutical preparations without prior separation steps from excipients as well as for determination of paracetamol in the presence of tramadol. The average recoveries for determination of mentioned drugs were 94.20-100.14%, and the average relative standard deviation of the method was better than ± 0.646%. ‫ﻤﺴﺘﺤﻀﺭ‬ ‫ﻓﻲ‬ ‫ﺍﻟﺘﺭﺍﻤﺎﺩﻭل‬ ‫ﻭﻫﻴﺩﺭﻭﻜﻠﻭﺭﻴﺩ‬ ‫ﺍﻟﺒﺎﺭﺍﺴﻴﺘﺎﻤﻭل‬ ‫ﺘﻘﺩﻴﺭ‬ ‫ﺍﺘﻬﻤﺎ‬ ‫ﺍﻟﺼﻴﺩﻻﻨﻴ‬ ‫ﺔ‬ ‫ﺒﻁﺭﻴﻘﺔ‬ ‫ﺨﻀﺭﺍﺀ‬ ‫ﻁﻴﻔﻴﺔ‬ ‫ﺍﻟﻤﻠﺨﺹ‬ ‫ﻭ‬ ‫ﺍﻟﺒﺎﺭﺍﺴﻴﺘﺎﻤﻭل‬ ‫ﺘﻘﺩﻴﺭ‬ ‫ﺘﻡ‬ ‫ﻫﻴﺩﺭﻭﻜﻠﻭﺭﻴﺩ‬ ‫ﻓﻲ‬ ‫ﺍﻟﺘﺭﺍﻤﺎﺩﻭل‬ ‫ﻁﻴﻔ‬ ‫ﺒﻁﺭﻴﻘﺔ‬ ‫ﺍﻟﺼﻴﺩﻻﻨﻴﺔ‬ ‫ﻤﺴﺘﺤﻀﺭﺍﺘﻬﻤﺎ‬ ‫ﻴﺔ‬ ‫ﻤﺄﻤﻭﻨﺔ‬ ‫ﻁﺭﻴﻘﺔ‬ ‫ﺒﺎﺴﺘﺨﺩﺍﻡ‬ ‫ﻋﺎﻟﻴﺔ‬ ‫ﻤﻀﺒﻭﻁﻴﺔ‬ ‫ﻭﺫﺍﺕ‬ ‫ﻭﺴﻬﻠﺔ‬. ‫ﻋﻠﻰ‬ ‫ﺍﻟﻁﺭﻴﻘﺔ‬ ‫ﺘﻌﺘﻤﺩ‬ ‫ﺇﺫﺍﺒﺔ‬ ‫ﻭﺘ‬ ‫ﺍﻟﻤﺎﺀ‬ ‫ﻓﻲ‬ ‫ﺍﻟﻤﺴﺘﺤﻀﺭ‬ ‫ﻤـﻭﺠﻲ‬ ‫ﻁـﻭل‬ ‫ﻋﻨﺩ‬ ‫ﺍﻟﺒﺎﺭﺍﺴﻴﺘﺎﻤﻭل‬ ‫ﻘﺩﻴﺭ‬ 242 ‫ﻨﺎﻨﻭﻤﻴﺘﺭ‬ ‫ﻤﻭﺠﻲ‬ ‫ﻁﻭل‬ ‫ﻋﻨﺩ‬ ‫ﺍﻟﺘﺭﺍﻤﺎﺩﻭل‬ ‫ﺘﺭﻜﻴﺯ‬ ‫ﺍﻴﺠﺎﺩ‬ ‫ﺜﻡ‬ 227 ‫ﻨﺎﻨﻭﻤﻴﺘﺭ‬ ‫ﻟﻨﻤﻭ‬ ‫ﺍﻻﻤﺘﺼﺎﺹ‬ ‫ﻤﻌﺎﺩﻟﺔ‬ ‫ﺒﺎﺴﺘﺨﺩﺍﻡ‬ ‫ﺫ‬ ‫ﻤﺘﻌﺩﺩ‬ ‫ﺝ‬ ‫ﺍﻟﻤﻜﻭﻨﺎﺕ‬. ‫ﺍﻅﻬﺭ‬ ‫ﺍﻟﺒﺎﺭﺍﺴﻴﺘﺎ‬ ‫ﺨﻀﻭﻋﺎ‬ ‫ﻤﻭل‬ ‫ﺍﻟﺘﺭﺍﻜﻴﺯ‬ ‫ﻤﻥ‬ ‫ﻟﻤﺩﻯ‬ ‫ﺒﻴﻴﺭ‬ ‫ﻟﻘﺎﻨﻭﻥ‬ 25-8 ‫ﺠﺯﺀ‬ / ‫ﻤﻠﻴﻭﻥ‬ ‫ﺍﻟﻤـﻭﺠﻲ‬ ‫ﺍﻟﻁـﻭل‬ ‫ﻋﻨـﺩ‬ 242 ‫ﻨـﺎﻨﻭﻤﻴﺘﺭ‬ ‫ﻭﻟﻤـﺩﻯ‬ 16-4 ‫ﺠﺯﺀ‬ / ‫ﻤﻠﻴﻭﻥ‬ ‫ﺍﻟﻤﻭﺠﻲ‬ ‫ﺍﻟﻁﻭل‬ ‫ﻋﻨﺩ‬ 227 ‫ﻨﺎﻨﻭﻤﻴﺘﺭ‬ ‫ﺍﻅﻬﺭ‬ ‫ﺤﻴﻥ‬ ‫ﻓﻲ‬ ‫ﺍﻟﺘﺭﺍﻤﺎﺩﻭل‬ ‫ﺨﻀﻭﻋ‬ ‫ﹰ‬ ‫ﺎ‬ ‫ﺍﻟﺘﺭﺍﻜﻴـﺯ‬ ‫ﻤـﻥ‬ ‫ﻟﻤﺩﻯ‬ ‫ﺒﻴﻴﺭ‬ ‫ﻟﻘﺎﻨﻭﻥ‬ 14-2 ‫ﺠﺯﺀ‬ / ‫ﻤﻠﻴﻭﻥ‬ ‫ﺍﻟﻤﻭﺠﻲ‬ ‫ﺍﻟﻁﻭل‬ ‫ﻋﻨﺩ‬ 227 ‫ﻨﺎﻨﻭﻤﻴﺘﺭ‬. ‫ﻓـﻲ‬ ‫ﺍﻟﻤﺫﻜﻭﺭﺓ‬ ‫ﻟﻼﺩﻭﻴﺔ‬ ‫ﺘﻁﺒﻴﻕ‬ ‫ﻗﺎﺒﻠﻴﺔ‬ ‫ﺍﻟﻁﺭﻴﻘﺔ‬ ‫ﺍﻅﻬﺭﺕ‬ ‫ﻤﺴﺘﺤـﻀﺭﺍﺘﻬﻤﺎ‬ ‫ﺍﻟﺼﻴﺩﻻﻨﻴ‬ ‫ـ‬ ‫ﺘﻘﺩﻴ‬ ‫ﻭﻜﺫﻟﻙ‬ ‫ﺔ‬ ‫ـ‬ ‫ﺍﻟﺒﺎﺭﺍﺴ‬ ‫ﺭ‬ ‫ـ‬ ‫ﺍﻟﺘﺭﺍﻤﺎﺩﻭل‬ ‫ﺒﻭﺠﻭﺩ‬ ‫ﻴﺘﺎﻤﻭل‬. ‫ﻟﺘﻘـﺩﻴﺭ‬ ‫ﺍﻻﺴـﺘﺭﺠﺎﻉ‬ ‫ﻨـﺴﺒﺔ‬ ‫ﻤﻌﺩل‬ ‫ﻜﺎﻥ‬ ‫ﺍﻷﺩﻭﻴـﺔ‬ ‫ﺍﻟﻤـﺫﻜﻭﺭﺓ‬ %100.14-94.20 ‫ﻟﻠﻁﺭﻴﻘﺔ‬ ‫ﺍﻟﻨﺴﺒﻲ‬ ‫ﺍﻟﻘﻴﺎﺴﻲ‬ ‫ﺍﻻﻨﺤﺭﺍﻑ‬ ‫ﻤﻌﺩل‬ ‫ﻭﻜﺎﻥ‬ ‫ﺃﻓﻀل‬ ‫ﻤﻥ‬ ± 0.646 % .
