Dabigatran Etexilate Mesylate (DEM), an anticoagulant used to treat and prevent blood clots and to inhibit the occurrence of stroke in people with cardiac arrhythmia. The purpose of this study was to obtain DEM co-crystals by screening eight different conformers and prepare the co-crystals by evaporation technique. Molecular docking was used to identify suitable coformer. Tartaric acid DEM co-crystals have been effectively prepared in the molar ratio of 1:1, 1:2, and 1:3 by solution-based evaporation technique. A 1:1 molar mixture of DEM and tartaric acid was further characterized. Differential scanning calorimetry, Fourier Transform Infrared Spectroscopy (FTIR), Powder X-ray Diffraction (PXRD) and Scanning Electron Microscopy (SEM) were used to characterize manufactured co-crystals. The study confirmed the selection of proper coformer and exhibited enhanced solubility and stability of the DEM co-crystals. Hence, based upon the above results, it revealed that co-crystallization helps in improving the physicochemical properties of the API, altering their chemical...

Background: The aim of this prospective study was to observe the efficacy of Trimetazidine (TMZ) and Isosorbide dinitrate (ISDN) in Coronary Artery Disease (CAD). Through inhibition of cardiac fatty acid oxidation, trimetazidine strengthens the treatment of CAD, by relieving aggravation; enhancing heart function, essential to prevent heart failure and other serious complications. Methods: 120 patients with CAD were selected as research subjects and randomly divided into two groups as observational (Group O) and control (Group C), with 60 patients in each group. The control group was on the conventional treatment of CAD whereas the observational group was using TMZ and ISDN along with the conventional treatment. The blood pressure, C-reactive protein (CRP), left ventricular ejection fraction (LVEF), troponin T and ST-segment levels of two groups were measured and compared at the baseline and after 2nd & 4th month respectively. Results: This study analyzed, compared to the baseline (P>0.05) the BP, CRP, troponin T and ST-segment levels after 2nd and 4th month were significantly decreased while LVEF increased significantly in...

The aim of the current investigation was to prepare and investigate the potential of Clobetasol (CP) loaded solid lipid nanoparticles based gel (SLN-gel) for the dermal delivery and to evaluate its anti-psoriatic efficacy by comparing with conventional ointment formulation. This study will provide an insight into the use of nanocarriers, esp. SLNs loaded with CP for the effective treatment of psoriasis. Clobetasol-loaded SLNs were formulated by the emulsification-homogenisation method and were characterized for particle size and polydispersity using DLS technique. The optimized SLNs were loaded into a gel and evaluated for drug release, spreadability. Anti-psoriatic efficacy of the SLNs gel was evaluated in imiquimod (IMQ) induced psoriatic plaque model by comparing with prepared conventional ointment formulation (0.05% w/w CP). Optimized SLNs attains a particle size of 133.3 ± 3.66 nm, polydispersity index (PDI) 0.179 ± 0.081, percentage entrapment efficiency of 78.1 ± 1.11% and Zeta potential of -36.2 ± 0.11 mV. The prepared SLNs gel was then compared with conventional ointment for drug release and efficacy. Topical application of...

In migraine disease which is an autoimmune disorder, 5-HT1 receptor agonist like Sumatriptan succinate (STS) is widely used. Its bioavailability is 15-17% due to extensive presystemic metabolism. The objective of this work was to prepare Sumatriptan succinate (STS) in a self nanoemulsifying drug delivery system (SNEDDS) and then convert it into solid-SNEDDS (S-SNEDDS) via extrusion/spheronization technique using Avicel pH 101, lactose monohydrate and Croscarmellose sodium. The component of SNEDDS was based on the solubility of STS in oily phases and surfactants. The screening of surfactants and cosurfactants were carried out in order to check its ability to emulsify the oily phase. Nanoemulsification area for the selected systems was identified by constructing the ternary phase diagrams. SNEP were characterized by scanning electron microscopy. SNEDDS composed of 30% Acrysol EL 135, 47% Tween 80 and 23% Capmul MCM C8. Its globule size was 98.4 nm, and zeta potential was -10.4 mV. S-SNEDDS possessed good mechanical strength and flow properties; angle of repose (25.79 ± 0.167), Hausner’s ratio (1.058 ± 0.03) and...

Canagliflozin is sodium-glucose co-transporter-2 inhibitors work by inhibiting SGLT2 to prevent reabsorption of glucose and facilitate its excretion in urine. Impurities in pharmaceuticals which are unwanted chemicals that remain with the active pharmaceutical ingredients (APIs), or develop during stability testing, or develop during formulation or upon aging of both API and formulation. The presence of these unwanted chemicals, even in small amounts, may influence the efficacy and safety of the pharmaceutical products. A simple and very sensitive method developed for estimation of impurities present in Canaglifozin formulation by Reverse Phase High Performance Liquid Chromatographic method. A method is capable to detect impurities at very low level (0.1 µm/mL). Chromatographic separation of six different impurities was achieved on inertsil C8-3 (250 × 4.6) mm, 3 µm column using gradient elution...
