Injectable solutions of ranitidine were prepared by dissolving ranitidine hydrochloride in water for injections. The following buffering system has been used: disodium phosphate (anhydrous), potassium dihydrogen phosphate, and phenol as a preservative. Inert gas (nitrogen) was used to displace oxygen from a solution and reduce the possibility of oxidative(More)
In recent years, drug release/dissolution from solid dosage forms has been the subject of intense and profitable scientific developments. Whenever a new solid dosage form is developed or produced, it is necessary to ensure that drug dissolution occurs in an appropriate manner. The pharmaceutical industry and the registration authorities do focus, nowadays,(More)
Complexes of β-cylodextrin with five nucleotides of adenine (A), thymine (T) guanine (G), cytosine (C), and 5-methylcytosine have been investigated using Hatree-Fock (HF) and density functional theory (DFT) calculations of different quality. This work was inspired by recent technological advances made in single-molecule sequencing of DNA. One molecule of(More)
