Simple, specific, accurate and precise UV-visible spectrophotometric methods have been developed for the estimation of five drugs viz., Dobutamine hydrochloride (DOB), Domperidone(DOM), Duloxetine hydrochloride(DUL), Phenylephrine(PHE) and Trimetazidine(TRM). These methods involve the addition of a known excess of NBS to the drugs in acid medium followed by estimation of residual NBS by reacting with a fixed amount of Indigo Caramine and measuring the absorbance at 520nm. Beer's law is obeyed in the concentration range of 0.6-4.2, 0.4-2.8, 0.3-2.1, 0.8-5.6 and 0.4-2.8 µg mL -1 for DOB, DOM, DUL, PHE and TRM respectively. Different variables affecting the reaction were studied and optimized. The proposed methods were applied successfully to the determination of the examined drugs in pure and pharmaceutical dosage forms with good accuracy and precision. The proposed methods were found to be successful for the estimation of these drugs in bulk and their formulations. The results of analysis have been validated statistically for linearity, accuracy, precision, LOD and LOQ.

Physiologically clotted fibrin‐calcined bone composite—A possible bone graft substitute

Fibrin plays a major role in blood clotting and is important in wound healing. In the present study, physiologically clotted fibrin (PF) and calcined bone (CB) both of bovine origin were used in the preparation of a bone graft material with chitosan (C) as a binder. This bone graft (PF-CB) was characterized by stress-strain analysis, X-ray diffraction (XRD) studies, scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis, and FTIR spectroscopy. Thermal studies revealed that the incorporation of CB into PF did not alter the thermal stability of fibrin, although it affects the total loss percentage. The composition containing 24:1:15 (PF:C:CB) on dry weight basis exhibited maximum compressive strength, and the same composite was used for characterization studies. The XRD studies have shown the amorphous nature of the implant. SEM pictures revealed the heterogeneity and porous nature of the implant. PF in combination with CB is expected to exhibit osteoinductivity because fibrin, the osteoinductive protein, acts as an angiogenic factor, whereas CB provides calcium and phosphate ions that are needed for new bone formation.
