Pharmaceutical drug formulation

Pharmaceuticals. Lecithin and especially purified phosphatidylcholine can act as excipients in pharmaceutical (drug) formulation to enhance and control the Unavailability of the active component. Moreover, phosphatidylcholine can be utilized as a diedelic source, as it involved in the cholesterol metabolism and the metabolism of fats in the liver also, it can be utilized as a precursor of brain acetylcholine, as neurotransmiticr.

Quantitative Determination of Active Ingredients in a Pharmaceutical Drug Formulation... 

The quantitative determination of the active ingredients forms only part of the quality control requirements for a pharmaceutical drug formulation. Equally important is the homogeneous distribution of the active ingredients in the formulation, and in this respect the inherent advantage of imaging measurements comes into play and provides the relevant information. As an example, in Figure 9.41 the...
