WHO identifies poor adherence is the most significant cause of uncontrolled blood sugar level. A prospective observational study was conducted in in-patients admitted to general medicine department diagnosed with diabetes mellitus from September 2019 to February 2020. Data was collected from case sheets of patients for age, gender, and socio- economic data. Informed consent was obtained from patients or bystanders before study. Direct interview was conducted with patients using standardized questionnaire known as MMAS-8. Patient’s adherence to medications was assessed using scores obtained from the adherence scale. Among 100 in-patients 62 (62%) patients were male and 38 (38%) patients were female. Most of the patients had low adherence among both genders. Patients under age group of 41-60 years were more (58%) in which 46% had low adherence. It was observed that, married patients were more with low adherence (58%) followed by unmarried. When taking account of education of the patient, graduates and above were only 22 patients (22%) but most of them (16% ) had moderate/high adherence. Education of the patients had a significant positive correlation (i.e., p value = 0.0000002) between low adherence and high adherence of patients. This study showed that the adherence to anti-diabetic medications in diabetic patients were very less. It needs to be continuously evaluated in order to reduce complications and improve quality of life of patients.</p> <p>Keywords: Medication adherence, MMAS-8, Uncontrolled diabetes</p> Nimmy N John V J Arjun DARATH DAVID H.

The antihypertensive effect of CC 4-16 mg/day was as great as that of other once-daily dosage regimens. Candesartan cilexetil has high first-pass metabolism and low oral bioavailability. The bioavailability of such drugs may be significantly improved if delivered through the buccal route; hence mucosal delivery is one of the alternative methods of systemic drug delivery. This study’s objective was to develop mucoadhesive buccal tablets of candesartan cilexetil using carbopol-934P, hydroxyl propyl methyl cellulose (HPMC), Eudragit RLPO, and sodium carboxy methyl cellulose (Na-CMC) as mucoadhesive polymers. Prepared CC buccal tablet formulations were evaluated for an optimized system based on physicochemical properties, ex-vivo residence time, in-vitro, and ex vivo permeation studies. The evaluation parameters of the tablets were within the acceptable Pharmacopoeial limits. However, the swelling and bio-adhesive time were increased with increasing polymer concentrations. The in-vitro release research shown that buccal tablets with sodium carboxy methyl cellulose (Na-CMC) exhibited a higher release than all other formulations and have been considered as optimized CC formulation. The release mechanism from kinetic methods suggests that the drug release follows zero-order kinetics with a diffusion mechanism. Further, <em>in-vivo</em> research in animal fashions is required to prove the bioavailability performance of the formulation.</p> <p>Keywords: Candesartan cilexetil, mucoadhesive buccal tablets, first-pass metabolism, bioavailability.</p> Kumara Swamy Samanthula Agaiah Goud Bairi CB Mahendra Kumar ##submission.copyrightStatement## 2021-02-15 2021-02-15 11 1-s 35 42 10.22270/jddt.v11i1-s.4547 Improvement of Physicochemical and Solubility of Dipyridamole by Cocrystallization Technology <p>The aim of this study was to develop a pH-independent release formulation of dipyridamole (DP) by the combined use of pH-modifier technology and cocrystal technology tartaric acid (TA) was selected as an appropriate pH-modifier in terms of improving physicochemical properties and dissolution behavior of DP under neutral conditions. Molecular docking method was used to identify the suitable conformer.&nbsp; Upon optimization of the ratio of TA to DP (molar ratio of 1:1, 1:2 and 1:3) was prepared by a solvent assisted griding method. Scanning electron microscopy images revealed that formation of DP-TA co crystals supported by supported by powder X-ray diffraction and differential scanning calorimetry analyses. Spectroscopic analysis suggested that there might be inter-molecular interaction among DP and TA resulting in pH independent dissolution behavior of drug substance. The study confirmed the selection of proper coformer and exhibited enhanced physicochemical, solubility and stability of the Dipyridamole cocrystals. Hence, based upon results it revealed that cocrystallization helps in improving the physicochemical properties of the API.</p> <p><strong>Keywords:</strong> Dipyridamole, Coformer, Molecular docking, Radar chart, solvent assisted griding, Cocrystals</p> Ashwini Gawade Ashwin Kuchekar Sanjay Boldhane Akshay Baheti ##submission.copyrightStatement## 2021-02-15 2021-02-15 11 1-s 43 48 10.22270/jddt.v11i1-s.4696 Development of High Performance Thin Layer Chromatography Method for Quantitation of Gallic Acid in Normacid Syrup: A Poly Herbal Formulation <p>Normacid syrup consisiting of 17 ingredients, used in the treatment of hyperacidity and gastritis.

With the appearance of the new coronavirus, end of 2019, several countries have recommended the use of herbal teas consisting mainly of <em>Artemisia</em>. The individual analysis of the constituents of this species is crucial to characterize and optimize its antiSARS-Cov-2 action. We evaluated by molecular docking the inhibitory action of major compounds of the Artemisia genus (Artemisinin, Arteannuin B, Alpha Thujone, P-Hydroxyacetophenone, Fisetin, Cirsimaritin, Capillin, β-Sitosterol, and Quercetin) against three targets namely SARS-CoV-2 main protease (Mp), SARS-CoV-2 receptor binding domain (RBD) and human furin protease (HF protease). The two flavonols, quercetin and fisetin, have the best binding energies with the three targets. Quercetin/Fisetin possesses binding energy of -7.17/-6.9, -6.3/-6.15 and – 5.98/- 5.49 kcal/mol with MP, RBD and HF protease respectively. Their physicochemical properties meet the requirements of an oral active principle and are not toxic according to predictive simulations. Thereby DFT calculation has been used to analyze the electronic and geometric characteristics of these two compounds. The gap energies were also deduced for the stable structure and their reactivity. The abundance of Quercetin in different plants may be another advantage in the use of this bio-compound in the treatment of coronavirus.</p> <p><strong>Keywords: </strong><em>Artemisia annua</em>, DFT, Docking Molecular, SARS-Cov-2, Quercetin and Fisetin</p> Abdirahman ELMI Ahmed Said MOHAMED Nazia SIDDIQUI Syad AL JAWAD Moustapha Nour Idriss MIGANEH Saleem JAVED ##submission.copyrightStatement## 2021-02-15 2021-02-15 11 1-s 71 82 10.22270/jddt.v11i1-s.4702 Corona Viruses and Human Leukocyte Antigen (HLA) alleles <p><strong>Major histocompatibility complex (</strong>MHC) is consisted of cluster of genes known as human leukocyte antigen HLA, these genes are committed to process and present antigens to T lymphocyte.

The therapeutic suitability of a new drug depends on the solubility. The solubility of the sparingly soluble drug remains a problem in identifying new active compounds. Solubility plays an important role in achieving optimal drug concentration. Low solubility is not only a concern for the production of formulations, but also an obstacle from the outset when identifying active chemicals for therapeutic purposes. Due to its simplicity in terms of ease of administration and economy, the oral route is the preferred route of drug administration over other routes. Effective aqueous solubility is the first prerequisite for oral medication, since low solubility has poor absorption and bioavailability and unpredictable toxicity of the gastrointestinal mucosa. To avoid these crises, different methodologies are used to improve the solubility and bioavailability of poorly soluble drugs, and hydrotropic solubilization is one of them. Hydrotropic agents have the potential to improve the solubility of water-insoluble drugs. In this review, we try to address hydrotropic solubilization methodologies.</p> <p>Keywords: Hydrotropy, Micelles, Solubility, Formulation.</p> Ashwin Bhanudas Kuchekar Ashwini Gawade Sanjay Boldhane ##submission.copyrightStatement## 2021-02-15 2021-02-15 11 1-s 200 206 10.22270/jddt.v11i1-s.4724 A Review on Pongamia pinnata (L.): Traditional Uses, Phytochemistry and Pharmacological Properties <p>Pongamia pinnata (L.)

In the prehistoric times medicinal plants were used by the various tribes. Evidence suggests that the people of Indus valley civilization followed this system of medicines. The Vedic and post Vedic period saw the rapid development of Ayurveda supported by the efforts of Charaka, Susrutra and Vagbhata etc. Buddhist monks played important role in the propagation of Ayurveda. However, the invasion of Muslims after 10th century destroyed Ayurveda and Unani system of medicines flourished in the country. Pre independence period again saw the emergence of Ayurveda. After Independence it attains new height with its incorporation into the Drug and Cosmetic Act. The preparation of Ayurvedic Pharmacopoeia helps in the standardization of Ayurvedic drugs to compete at global level with allopathic system of medicines.</p> <p>Keywords: ayurvedic system, Vedic and post Vedic period, Charaka, Susrutra and Vagbhata, Ayurvedic drugs</p> S.
