Alprazolam Kinetic Incompatibility DSC Aprazolam is triazolo analog of the benzodiazepine class psychoactive drugs and works by binding to specific sites on the gamma-aminobutyric acid ( GABA ) receptor s. This drug is used to treat anxiety and panic disorders and has other pharmaceutical effects such as sedative , hypnotic , skeletal muscle relaxant and anticonvulsant Alprazolam (8-Chloro-1-methyl-6-phenyl-4 H -[1,2,4]triazolo[4,3-a][1,4]benzodiazepine) is available for oral administration in compressed tablet and extended-release capsule formulations [ 1 , 2 ]. Thermal methods such as differential scanning calorimetry (DSC), differential thermal analysis (DTA) and thermogravimetry (TG) are well-established techniques in assessment ...

The chemical structure of HPMC represents a hydrogen atom, or the methoxy or hydroxypropyl functional groups, which when substituted onto the cellulose backbone affect the physiochemical properties [ 25 ]. However, the inflexibility/viscosity of the resulting mass is directly related to the concentration of the methoxy group (the higher the concentration, the higher the inflexibility/viscosity) [ 26 ]. The process consists of at least 6 steps: preparation of the casting solution aeration of the solution transfer of the appropriate volume of solution into a mold drying the casting solution cutting the final dosage form to contain the desired amount of ...

Mucoadhesive Film Buccal Hydroxypropyl methylcellulose Carbomer 934p Eudragit RL  100 Polyvinylpyrrolidone Drug delivery through the mucosal linings of the oral cavity can offer various benefits over oral systemic drug delivery including the bypass of the first-pass effect, the prevention of the presystemic elimination within the gastrointestinal tract and—related to the special drug and mucosal portal—a small enzymatic flora for drug destruction [1]. The oral cavity is very desirable by patients; the mucosa is partly permeable and has a high blood circulation. Moreover, it is huge and displays little improvement times after stress or injury. Thus, the oral cavity seems to be ...
