OBJECTIVE To determine the prevalence of dysmenorrhea, effect on daily activity, academic activities, quality of life, and knowledge of management in Siriraj medical students. MATERIAL AND METHOD A cross-sectional descriptive study at the Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand that included 552 female medical students who were asked to complete two questio...

A novel mutual prodrug (MA-P) consisting of mefenamic acid (MA) and paracetamol (P) has been synthesized as a gastrosparing NSAID, devoid of ulcerogenic side effects. The structure of synthesized drug was confirmed by elemental analysis, infrared spectroscopy, 1H NMR spectroscopy and mass spectrometry.The kinetics of ester hydrolysis was studied by HPLC at pH 2, pH 7.4 as well as in human plasm...

Coloration of mefenamic acid (MFA) was investigated in the presence of mesoporous silica FSM-16 with 16.0 A (Oc) and 45.0 A (Doc) pore diameter. The color change of MFA/FSM-16 physical mixture from white to deep blue was observed by sealed-heating (SH) and the subsequent humidification (HU). The coloration and the color difference were caused by the changes of chroma and lightness. In the case ...

The objective of the study was to prepare mefenamic acid (MA) sustained release matrix pellets and investigate the formulation parameters affecting pellet attributes and drug release in vitro. Amixer torque rheometer (MTR) was used to characterize the rheological properties of wet mass used in pellet formulation. Mefenamic acid pellets were prepared by extrusion/spheronization techniques using ...

Time-course studies on gastric damages in rats caused by nonsteroidal anti-inflammatory drugs (NSAIDs) were performed using a gastroscope, and the readings were quantified to obtain the Congestion-Hemorrhage Index (CHI) for evaluating the potencies of the damaging properties of NSAID. The correlation between CHI and Ulcer Index (UI), the quantified value obtained by the conventional methods, wa...

Article history: Received on: 11/05/2016 Revised on: 30/06/2016 Accepted on: 16/08/2016 Available online: 29/10/2016 Mefenamic acid (MFA) and Nicotinamide (NIC) cocrystal formation in co-milling treatment was investigated by x-ray powder diffractometry (XRPD). Two polymorphic form of Mefenamic acid (MFA form I and MFA form II) were used to form a cocrystal with nicotinamide. Co-milling treatmen...
