Formulation studies then consider such factors as particle size, polymorphism, pH, and solubility, as all of these can influence bioavailability and hence the activity of a drug. The drug must be combined with inactive ingredients by a method that ensures that the quantity of drug present is consistent in each dosage unit e.g. each tablet.
The model calculations show that the liquid phase forms at lower temperatures for smaller nanoparticles. Once the liquid phase forms, the free energy conditions quickly change and favor melting. Equation 6 gives the melting conditions for a spherical nanoparticle according to the LNG model. [20]
Galenic formulation deals with the principles of preparing and compounding medicines in order to optimize their absorption.Galenic formulation is named after Claudius Galen, a 2nd Century AD Greek physician, who codified the preparation of drugs using multiple ingredients.
Physical pharmacy is the branch of pharmacy that concentrates on the applications of physics and chemistry to the study of pharmacy. In other words, it is the study of the effects that dosage forms have on their environment by addressing issues at the molecular level. [1]
In the physical sciences, a partition coefficient (P) or distribution coefficient (D) is the ratio of concentrations of a compound in a mixture of two immiscible solvents at equilibrium.
Hit to lead (H2L) also known as lead generation is a stage in early drug discovery where small molecule hits from a high throughput screen (HTS) are evaluated and undergo limited optimization to identify promising lead compounds.
New data from Freddie Mac shows the benchmark 30-year fixed-rate mortgage trending at its highest levels since July as of Friday, January 3, 2025, while average rates drift lower to end a week of ...
