چکیده
Purpose: The aim of this study is to develop bromhexine hydrochloride 1 %w/v oral solution for veterinary use and to evaluate its stability. Methods: Solutions of Bromhexine hydrochloride (1%w/v) were prepared by dissolving bromhexine hydrochloride in benzyl alcohol at 50 °C then alcohol 96 % v/v; Tween 80 and purified water were added. The obtained solution was filled in amber glass bottles, and the solution was stored at 25 °C/60 % relative humidity (RH) and at 40 °C /75% RH. The strengths of bromhexine hydrochloride were determined by High performance liquid chromatographic assay at 0, 2, 4, 6, 8, 10, 12, 16, 20 and 24 months. The concentrations of the drug were directly related to the peak area. pH, odor, color and crystal formation was also monitored. Results: The degradation of bromhexine hydrochloride 1% w/v oral solution was faster at 40 °C/75% RH than at 25 °C /60% RH. No significant differences were found between the initial and final pH value for the solution at the studied conditions. No detectable changes in color, odor or precipitations were observed for the solutions stored at the upper conditions. Conclusions: Bromhexine hydrochloride 1% w/v oral solution could be formulated and remains stable for at least 2 years when is stored at 25°C /60% RH and for 16 months when stored at 40 °C /75% RH. صخلملا : ثحبلا فده : زـيكرتب يوـمف لولحم راكتبا وه ةساردلا هذه فده 1 % ةداـم نـم ياه نيسكهمورب د لال كلذ وديارولكور يرطيبلا مادختس ، ب ا يئاملا لولحملا اذه ةيتابث مييقت ىلإ ةفاضلإ . أ ثحبلا بولس : نم لولحم ريضحت مت لا ديه نيسكهمورب ب كلذ و ديارولكور هـتباذإ لوـحكلا يـف ةرارح ةجرد ىلع يليزنبلا 50 ةيوئم ، لوحكلا ةفاضإ مت مث نم و ، نيوتلا 80 ، ىلع ىقنملا ءاملا و يلاوتلا . اهضعب نيزخت مت ثيح ةنكاد ةيجاجز بلع يف هيلع لوصحلا مت يذلا لولحملا ةئبعت تمت ةرارح ةجرد ىلع 25 و ةيوئم 60 % ةيبسن ةبوطر ، بلا و ةرارح ةجرد ىلع هنيزخت مت رخلآا ضع 40 و ةيوئم 75 % ةيبسن ةبوطر . زيكارت ريدقت مت لا صـحفلا ةطـساوب ديارولكورديه نيسكهمورب لأا يـف كلذ و ةيلاعلا تاردقلا وذ يلئاسلا يفارغوتاموركلا رهـش 0 ، 2 ، 4 ، 6 ، 8 ، 10 ، 12 ، 16 ، 20 و 24 ، تحت ةحاسملا ةنراقم قيرط نع ءاودلا زيكرت باسح مت ىنحنملا نـم لك صحف مت امك pH ارلا ، ئ لا ،ةح ل تابسرتلا و نو . جئاتنلا : لولحملا يف ديارولكورديه نيسكهموربلا ةدام يف ككفتلا يومفلا 1 % ةرارح ةجرد ىلع ةنزخملا تانيعلا يف عرسأ ناك 40 و ةيوئم 75 % ةيبـسن ةبوطر Formulation and stability evaluation of 1% w/v oral 14 ةرارح ةجرد ىلع نزخملا كلذ عم ةنراقم 25 و ةيوئم 60 % سن ةبوطر ةيب ، امك أ قورف دجوت لا هن يف pH اهتياهن و ةساردلا ةيادب نيب . لولحملا ةحئار و نول يف رييغت يأ دجوي لا ، دجوت لا هنأ امك ةساردلا ةرتف ةليط ةروكذملا فورظلا تحت ةنزخملا تانيعلا يف تابسرت . لاا جاتنتس : ياه نيسكهمورب يومفلا لولحملا ريضحت نكمي د يارولكور د 1 % ث هؤاقبإ و اتبا لقت لا ةدمل ةرارح ةجرد ىلع هنيزخت دنع نيتنس نع 25 و ةيوئم 60 % ةيبسن ةبوطر ، نع لقت لا ةدمل و 16 ارهش " ةرارح ةجرد ىلع هنيزخت دنع 40 و ةيوئم 75 % ةيبسن ةبوطر .
