The elemental composition of seven soils of the main geographical regions in Bulgaria for the growth of Leucojum aestivum L. was determined. It was found that a relationship exists between the galanthamine content of the plant and the chemical compos

Galanthamine hydrobromide (Nivalin, dose 10 mg) was given subcutaneously and orally to 8 volunteers. Galanthamine and its metabolites were quantified in plasma and urine by reversed-phase HPLC. An unusual two-stage absorption and biexponential drug d

The influence of suppository base and some tensides on the release and resorption of theophylline from model rectal suppositories was investigated in a preliminary way. It was established that the original Bulgarian suppository base Novosup ensures h

A program NABTIT written in BASIC has been developed for the treatment of data (ml/mV) obtained from potentiometric acid—base titrations in non-aqueous solvents. No preliminary information on equilibrium constants is required for the input. The tre

A new approach to the graphic extrapolation procedure is proposed for the determination of pK-value of pharmaceuticals poorly soluble in water. It is based on a direct potentiometric method for the determination of acid-base constants in non-aqueous

A method is proposed both for the quantitative determination and identification of pharmaceuticals, based on the data of a single pH-metric titration. As a new identification criterion the pK-value of the pharmaceutical is proposed. The latter is con
