Levofloxacin effervescent sustained release tablets were developed in eight different formulations (F1 to F8) by employing different grades of polymers and effervescent agents such as sodium bicarbonate and citric acid. The formulations were evaluated for various physical parameters, dissolution parameters and drug released mechanisms. F8 formulation showed maximum floating time of 12 hours and...

Binder jet three-dimensional (3D) printing has been extensively developed since the early 1990s and is widely applied in various industrial fields. jetting 3D-printed products have anisotropic mechanical properties; however, no study provided a systematic explanation of this mechanism. Herein, we propose that crystal lattice model based on crystallographic logic can explain anisotropy fracture ...

The title compound, C(8)H(5)BrN(2)·0.5H(2)O, is a phthalazine derivative synthesized from 3-bromo-benzene-1,2-dicarbaldehyde and hydrazine. The mol-ecule is essentially planar, the deviation from the mean plane of the phthalazine ring being 0.015 (3) Å. The O atom of the solvent water mol-ecule is situated on a twofold rotation axis. In the crystal, O-H⋯N hydrogen bonds and short N⋯Br [2.980 (3...

methylamino)-3,5,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-1,4,4a,5,5a,6,11,12a-octahydrotetracene-2-carboxamide hydrochloride hemiethanol hemihydrate (Fig. 1), is one of the tetracycline derivatives, which has a wide range of antibacterial activities. DOX is frequently used to treat chronic prostatitis, sinusitis, syphilis, chlamydia, pelvic inflammatory disease, acne, rosacea, and rickettsia...
