Research summary
تهدف هذه الدراسة إلى تقييم تأثير مشاركة هيدروكسي بروبيل ميتيل سلولوز (HPMC) مع مشتقات عديد الميثاكريلات (Eudragit RS, RL & L100) في ضبط تحرر دواء كيتوبروفن من أقراص القالب. تم تحضير أربع مجموعات من الأقراص تحتوي على نسب مختلفة من البلمرات المدروسة، وأجريت فحوص فيزيائية وفحص الذوبان وفقًا لدستور الأدوية الأمريكي (USP32). أظهرت النتائج أن الأقراص التي تحتوي على HPMC وحده أظهرت تحررًا سريعًا في الساعة الأولى، بينما الأقراص التي تحتوي على مزيج من HPMC و Eudragit لم تظهر هذا التحرر السريع. تم تحليل أنماط حركية التحرر باستخدام معادلات مختلفة، وأظهرت النتائج أن معادلة التحرر من الرتبة صفر ومعادلة كورس ماير وبيباس كانت ملائمة لأغلب نتائج الذوبان. كما أظهرت الدراسة أن مشاركة البلمرات تزيد من قيمة معامل التحديد (R2) وفق معادلة التحرر من الرتبة صفر مقارنة بالأقراص التي تحتوي على HPMC وحده.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال الصيدلة والتكنولوجيا الصيدلانية، حيث تقدم معلومات قيمة حول تأثير مشاركة البلمرات المختلفة في ضبط تحرر الأدوية. ومع ذلك، يمكن أن تكون هناك بعض النقاط التي تحتاج إلى مزيد من التوضيح. على سبيل المثال، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية مثل درجة الحرارة والرطوبة على تحرر الدواء. كما أن الدراسة ركزت بشكل كبير على الجانب النظري والتحليلي دون تقديم تجارب عملية مكثفة لدعم النتائج. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة لمزيد من الدراسات لتقييم تأثير هذه البلمرات على الأدوية الأخرى وليس فقط على كيتوبروفن.

The objective of the present study was to formulate methyldopa sustained release matrix tablets using hydrophilic hydroxypropyl methylcellulose (HPMC) alone or in combination with hydrophobic ethyl cellulose polymer(EC). Matrix tablets were prepare d by wet granulation method, and subjected to physiochemical studies. All formulations showed physiochemical properties which appear to be in compliance with pharmacopeial standards. The in-vitro dissolution studies showed that increase in concentration or viscosity of HPMC polymer led to decrease in the rate of drug release decreased. The results also revealed that Combination of HPMC K4M and EC slower drug release more than using HPMC K4M alone. Drug release kinetics of about all formulations correspond best to Korsemeyer-Peppas model and drug release mechanism was anomalous diffusion based on release exponent value.
Methyldopa, an anti-hypertensive drug having a half life of less than 2 hours, and given with a dose of 250 mg 3-4 times daily. Objective: The present study was for objective of developing a sustained release (SR) matrix tablets of methyldopa usin g hydroxypropyl methylcellulose(HPMC) as release controlling factor, and to study the effect of some formulation factors on drug release from tablets. Methods: Hydrophilic SR matrix tablets containing 250 mg of methyldopa were prepared using wet granulation method. Granules were evaluated for moisture content, loose bulk density, tapped bulk density, compressibility index and hausner’s ratio. Tablets were subjected to physiochemical studies and in vitro dissolution study. Effect of concentration and viscosity grade of HPMC, both binder and lubricant concentration on drug release from matrix tablets was evaluated . Results: All formulations showed physiochemical properties which appear to be in compliance with pharmacopeial standards. From the in vitro dissolution studies, it was clear that as the concentration or viscosity of polymer increased, the rate of drug release was found to be decreased. Higher concentration of binder (PVP K30) showed slower release of drug, while the level of lubricant(magnesium stearate and talc) appeared to insignificantly affect release rates. Drug release kinetics of about all formulations correspond best to Korsemeyer-Peppas model and drug release mechanism was found to be anomalous (non-Fickian) diffusion based on release exponent value. The formulation F6 (containing 15% HPMC K100M ) was selected as the optimized formulation as it sustained the release over 24 hrs. Conclusion: The results of this study showed that the drug release from HPMC based matrix tablets using methyldopa as a drug model could be modulated by varying the polymer concentration, the polymer viscosity and the binder concentration with no significant effect of varying the lubricant concentration.
The present study aims to develop sustained release (SR) matrix tablets of methyldopa using hydrophilic hydroxypropyl methylcellulose (HPMC), and to study the effect of some formulation variables (HPMC concentration and viscosity grade, combination with hydrophobic Ethylcellulose (EC) in different ratio, binder and lubricants concentrations) on the properties of prepared tablets. Matrix tablets were prepared by wet granulation method, and prepared granules and tablets were subjected to suitable physiochemical studies. Drug release kinetics showed that drug release mechanism for about all formulations was found to fit best to Higuchi model and drug release mechanism was anomalous diffusion based on release exponent value. The in-vitro dissolution studies showed that formulation F6 containing 15% of HPMC K100M and formulation F11 containing EC:HPMC K4M (5%:10%) were able to sustain the release of methyldopa up to 24 hours so these two formulations were selected as suitable formulations.
The purpose of this study was to prepare prolonged release tablets of verapamil: matrix and coated tablets, because of the importance of these systems in drug delivery and improving the patient compliance and therapeutic efficacy .Different formula tions were prepared by using different release-modifiers polymers (EURL100 and EURS100). Direct compression technique was used to prepare coated tablets while matrix tablets were prepared by wet granulation and direct compression methods. The prepared formulations were evaluated in terms of their precompression parameters, physical characteristics, dissolution test and in vitro drug release kinetic studies. The results showed that matrix tablets containing 7.5or10% of EuRS100 and EuRL100 respectively and that coated tablets prepared by using coating solution (15%) which was applied about 120(in case of EuRS100) or 280 (in case of EuRL100) times were the best. These tablets released about 90-95% of verapamil within 24h
The increasing number of individuals with diabetes suggests that diabetic retinopathy DR is a major contributor to vision loss. The initial disease is characterized by increased vascular permeability due to a breakdown in the blood-retinal barrier BRB, causing macular edema DME, with a progressive vascular occlusion and retinal neovascularization which are secondary to ischemia and oxidative stress. Laser photocoagulation and vitrectomy only target advanced stages of disease. However, despite laser treatment, patients with DME experienced gradual loss of vision. Intravitreal triamcinolone IVTA reduces the breakdown of BRB and down-regulates the production of vascular endothelial growth factor VEGF. IVTA may moderately but temporarily improves visual acuity in cases of DME. Agents that attenuate VEGF action such as bevacizumab are expected to reduce permeability and neovascularization. Intravitrealbevacizumab IVB reduces macular edema secondary to central retinal vein occlusion, vascular permeability and fibrovascular proliferationin. Calcium dobesilate CD is a potent antioxidant, slows vascular proliferation.
