Solvent evaporation technique was used to prepare microspheres, where Methocel K15M CR (X<sub>1</sub>), Eudragit L 100 (X<sub>2</sub>) and rpm (X<sub>3</sub>) were used as independent variables whereas percent cumulative drug release at 8 hours (Y<sub>1</sub>), bond strength (Y<sub>2</sub>) and swelling at 8 hours (Y<sub>3</sub>) were used as dependent variables. Particle size, surface morphology, mucoadhesive bond strength, swelling study, and drug entrapment efficiency were determined to characterize the prepared microspheres. <em>In vitro </em>dissolution study was performed in 0.1N HCl (pH 1.2) media for 8 hours. Response surface of dependent variables was calculated by design expert software and it was found that most of the responses were fitted to the quadratic model. Percent cumulative drug release at 8 hours was found minimum 61.34% and maximum 87.29%, the minimum and maximum range of mucoadhesive bond strength was found 426.02 to 13335.74 N/m<sup>2</sup> and in case of swelling at 8 hours, it was found 157.43 and 230.22%. After analyzing the responses, proposed formula was obtained from which minimization of percent cumulative drug release at 8 hours as well as swelling and maximization of bond strength was obtained. Thermal behavior was investigated by DSC study and no interaction was found between drug and excipients from FTIR study.</p> <p>Bangladesh Pharmaceutical Journal <strong>22</strong>(2): 135-145, 2019</p> Aditi Bhowmick, Tushar Saha, James Regun Karmoker, Md Selim Reza ##submission.copyrightStatement## https://www.banglajol.info/index.php/BPJ/article/view/42297 Sun, 21 Jul 2019 00:00:00 +0000 Isolation and Characterization of Malasezzia Species from Dandruff Samples and Determination of its Sensitivity Towards Antifungal Agents https://www.banglajol.info/index.php/BPJ/article/view/42298 <p>Dandruff is a perennial skin condition manifesting as inflammation and physiologic scaling on the scalp. <em>Malassezia </em>species are the part of the skin microflora of humans and the etiological agents of dandruff. <em>Malassezia </em>comprises of lipophilic and non-lipophilic yeasts. At present topical azoles are used for the treatment of dandruff. This study was conducted to isolate and identify the <em>Malassezia </em>spp. from dandruff samples and to determine their responsiveness towards antifungal agents such as fluconazole, ketoconazole, miconazole and nystatin. <em>Malassezia </em>spp. was isolated using selective media and identified by biochemical tests and microscopic examination. Antifungal activities were assessed by the Kirby Bauer method using well diffusion technique. Total fifteen <em>Malassezia </em>spp. including <em>M. furfur</em>, <em>M. pachydermatis, M. sympodialis </em>and <em>M. globosa </em>were identified from twenty five dandruff samples. Among them, <em>M. furfur </em>was most prevalent (66.67%) followed by <em>M. pachydermatis </em>(13.33%), <em>M. sympodialis </em>(13.33%) and <em>M. globosa </em>(6.67%). All strains were sensitive to the antifungal agents but to different extent. Fluconazole and ketoconazole proved to be the most effective agents against these microorganisms.</p> <p>Bangladesh Pharmaceutical Journal <strong>22</strong>(2): 146-152, 2019</p> Kohinur Begum, Farjahan Nur, Mashmum Shababa Shahid ##submission.copyrightStatement## https://www.banglajol.info/index.php/BPJ/article/view/42298 Sun, 21 Jul 2019 00:00:00 +0000 Formulation and In-vitro Evaluation of Bilayer Tablets of Atenolol and Amlodipine https://www.banglajol.info/index.php/BPJ/article/view/42299 <p>The present investigation was focused on formulation and <em>in-vitro </em>evaluation of a fixed dose bilayer tablet of two prominent antihypertensive agents, atenolol and amlodipine. The tablets were designed to immediately release atenolol (ATF1-ATF5) by using different percentage of sodium starch glycolate as super-disintegrant for prompt blood pressure lowering activity and sustain release amlodipine (AMF1- AMF5) by varying the percentage of hydroxy propyl methylcellulose (HPMC) for prolonged activity. After evaluation of the physical and chemical parameters of the formulations according to United States Pharmacopoeia (USP) guidelines, the best immediate release formulation was found in ATF1 in terms of dissolution (99.87% after 45 minutes) and other tablet properties like hardness, disintegration time, good flow properties etc. However, the best sustained release activity was found in AMF3 in terms of dissolution (99.98% after 24 hours with constant release) and other tablet properties. After optimization of the formulations, both atenolol and amlodipine parts were successfully compressed into bilayer tablets and post-compression parameters were evaluated. In 0.1 N HCl medium, the release of atenolol from bilayer tablet was found 98.97% after 45 minutes and in case of amlodipine it was found 98.12% in 0.1 N HCl medium followed by phosphate buffer medium after 24 hours. Drug release kinetics showed that the atenolol layer followed Case I, QasiFickian transport and amlodipine layer followed Anomalous (non-Fickian) transport. Compatibility study was conducted by using Fourier Transform Infrared Spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC). Moreover, crystalline nature of substances and extent of its conversion to amorphous form was studied using X-ray Diffractometry (X-RD).</p> <p>Bangladesh Pharmaceutical Journal <strong>22</strong>(2): 153-169, 2019</p> KM Yasif Kayes Sikdar, Ahad Ahamed, Md Mahbubul Alam, Md Raihan Sarkar, BK Sajeeb ##submission.copyrightStatement## https://www.banglajol.info/index.php/BPJ/article/view/42299 Sun, 21 Jul 2019 00:00:00 +0000 Preparation and In-vitro Characterization of Gastroretentive Floating Tablets of Domperidone https://www.banglajol.info/index.php/BPJ/article/view/42300 <p>The present investigation was design for domperidone floating table preparation and <em>in-vitro </em>characterization. The ultimate target was increasing gastric retention by means of floatability of the tablet. Hydrophilic cellulosic polymers, Methocel K15M and Methocel K100M were used in this experiment for achieving release controlling property. Sodium bicarbonate played the key role of floatation by generating gas. Direct compression was the method of choice for preparing the tablets. The tablets were evaluated for physical parameters, buoyancy study, total floating time determination and dissolution study. Acidic dissolution medium (0.1N HCl), mimicking the environment of the stomach, was used in USP II apparatus for 12 hours to find out the pattern of drug release. The release mechanism was analyzed by exploring the zero order, first order, Higuchi and Korsmeyer equations. All the physical parameters were within acceptable range and Methocel K100M showed more floating lag time and sustained release property than Methocel K15M. All the formulations showed more than 12 hours floating time. Fourier Transform Infrared Spectroscopy (FTIR) study confirmed the compatibility of the drug with the excipients.</p> <p>Bangladesh Pharmaceutical Journal <strong>22</strong>(2): 170-175, 2019</p> Ikramul Hasan, Tushar Saha, Md Selim Reza ##submission.copyrightStatement## https://www.banglajol.info/index.php/BPJ/article/view/42300 Sun, 21 Jul 2019 00:00:00 +0000 In vivo Anti-diarrheal and CNS Depressant Activities of Hemigraphis hirta (Vahl) T. Anders. https://www.banglajol.info/index.php/BPJ/article/view/42301 <p><em>Hemigraphis hirta </em>has been used by folk practitioners to alleviate symptoms of several diseases, although the pharmacological activities of this plant have not been thoroughly explored. The current study was designed to assess the anti-diarrheal and CNS depressant activities of <em>H. hirta </em>in mice model. For both assays, the experimental mice received the methanolic crude extract and its petroleum ether soluble fraction at dose of 200 and 400 mg/kg body weight which are denoted as CME 200, CME 400, PESF 200 and PESF 400, respectively. Both fractions remarkably attenuated castor oil-induced diarrheal effect in a dose-dependent manner and the results were comparable to standard loperamide (89.47%). Among all, PESF 400 exhibited statistically significant (p &lt; 0.01) anti-diarrheal activity as demonstrated by 78.95% inhibition of defacetion. Compared to reference drug diazepam, all the tested samples considerably shortened the time for onset of sleep and prolonged the duration of phenobarbitoneinduced sleep in mice. The results of our present study, being reported for the first time, demonstrate that the methanol extract of leaves of <em>H. hirta </em>and its organic soluble partionates possesses significant anti-diarrheal and CNS depressant properties. However, this preliminary screening requires further detailed investigation to confirm these findings as well as to isolate and characterize the bioactive compounds.</p> <p>Bangladesh Pharmaceutical Journal <strong>22</strong>(2): 176-180, 2019</p> Md Shahidulla Kayser, Moazzema Binta Bashar, Tufael Ahmed, DA Anwar Al Aman ##submission.copyrightStatement## https://www.banglajol.info/index.php/BPJ/article/view/42301 Sun, 21 Jul 2019 00:00:00 +0000 Boehmeria glomerulifera Miq.

It is therefore important to identify plants with antidiarrhoeal activity<strong>. </strong><em>Melochia corchorifolia </em>and <em>Glochidion thomsonii </em>have been used in folk medicine to alleviate several diseases. The present study was performed to investigate the anti-diarrheal properties of ethanolic extract of <em>M. corchorifolia </em>whole plant and <em>G. thomsonii </em>bark. Anti-diarrheal potential was evaluated using castor oil and MgSO4 induced diarrhea, GI motility test as well as castor oil induced enteropooling assay in mice. Extracts were used at 250 and 500 mg/kg per orally. Loperamide (10 mg/kg p.o) was used as standard drug. The ethanolic crude extracts exhibited statistically significant and dose-dependent (250 and 500 mg/kg) anti-diarrheal effect against the total number of episodes of defecation as well as diarrheal feces. In animals pretreated with MC and GT extract showed 42.53% (p&lt;0.05) and 53.13% (p&lt;0.001) protection at a dose of 250 mg/kg and 89.40% (p&lt;0.001)and 57.47% (p&lt;0.001) protection at 500 mg/kg against castor oil induced diarrhea. The MC extract at 500 mg/kg exhibited significant (p&lt;0.05) inhibition of diarrhea (51.04%) in MgSO4 induced diarrhea. In BaSO4 induced GI motility test both the extracts inhibited GI motility and GT at 500 mg/kg dose 38.77% which was highly significant (p&lt;0.01). In the Castor oil induced enteropooling assay MC 250 and 500 mg/kg and GT 250 and 500 mg/kg reduced the intestinal fluid accumulation by 27.42% and 48.39% (p&lt;0.01) and 38.71% (p&lt;0.05) and 51.61% (p&lt;0.01), respectively.

Solvent casting method was used to prepare the films. Compatibility between drugs and excipients were studied using FTIR and HPLC. Nine different formulations of film from F1 to F9 were prepared using different concentration of polymer A at drug-polymer A ratio (1:26), (1:28), (1:30), (1:32), (1:34), (1:36), (1:38), (1:40), (1:42) and at polymer A-plasticizer B of (65:10), (70:10), (75:10), (40:10), (42.5:10), (45:10), (47.5:10), (50:10), (52.5:10), respectively. The <em>in vitro </em>dissolution study was carried out in phosphate buffer (pH 6.8) at 37±0.5<sup>o</sup>C and 50 rpm using USP XXIV paddle method. Physicochemical evaluations of all the batches were performed including weight variation, thickness, folding endurance, pH, <em>in vitro </em>disintegration and drug release, FTIR and content uniformity test. Maximum and minimum drug dissolution were found in F6 (108.7%) and in F1 (98.5%), respectively. The maximum and minimum disintegration time were in F9 (43.8 sec) and F1 (25 sec), respectively which demonstrated that disintegration of the film was directly proportional to the polymer A and plasticizer B concentration. It is quite evident from the present research work that the film prepared using polymer A-plasticizer B were smooth, mechanically strong and easy to peel out. Among all the batches, formulation F5 showed best results with respect to disintegration (33 sec), drug dissolution (105%), content uniformity (98.51%) and folding endurance (731). Therefore, it can be said that combination of polymer A and plasticizer B can be prospectively used for the preparation of palonosetron hydrochloride oral thin film.</p> <p>Bangladesh Pharmaceutical Journal <strong>22</strong>(2): 228-234, 2019</p> Sreebash Chandra Bhowmik, Marzia Alam, Md Saiful Islam Pathan ##submission.copyrightStatement## https://www.banglajol.info/index.php/BPJ/article/view/42316 Sun, 21 Jul 2019 00:00:00 +0000 A Mini Review on the Chemical Compounds of the Genus Acacia https://www.banglajol.info/index.php/BPJ/article/view/42317 <p>The genus <em>Acacia </em>is a pioneering source of diversified chemical compounds.
