Critical solution temperature (CST) and distribution law
Critical solution temperature (CST) and distribution law The Critical Solution Temperature (CST) is the temperature at which two partially miscible liquids become completely miscible in all proportions. There are two types: the Upper Critical Solution Temperature (UCST), above which the liquids are fully miscible, and the Lower Critical Solution Temperature (LCST), below which they are…

Solubility of Gases in Liquids, binary solutions, Roult’s law
Solubility of Gases in Liquids When a gas dissolves in a liquid, it forms a solution. The solubility of a gas in a particular liquid refers to the volume of that gas (converted to standard temperature and pressure conditions) that can dissolve in one cubic centimeter (1 cc) of the liquid. This process occurs at…

Factors affecting solubility of drugs
Factors affecting solubility of drugs When it comes to designing effective pharmaceutical formulations, understanding the solubility of drugs is crucial. Poor solubility can lead to suboptimal drug delivery, variable bioavailability, and ineffective treatment. These factors interact with each other, and their impact can vary depending on the specific drug and its chemical properties. So, let’s…

Solvation and Association
Solvation and Association In the intricate dance of pharmaceutical science, where molecules waltz in solution, two central partners emerge: solvation and association. These concepts, akin to the choreography of drug formulation, dictate the fate of therapeutic agents within our bodies. So, let us unravel their steps, adhering to the precise language found in textbooks. Solvation…

Ideal solubility parameters
Ideal solubility parameters Ideal solubility parameters (ISPs) are like the secret handshakes they exchange. ISPs consider three forces: dispersion (think subtle nods), polarity (like magnets finding their match), and hydrogen bonding (warm chemistry hugs). When a drug meets a solvent, they dance—matching ISPs mean better solubility. It’s molecular harmony. Formulators use ISPs to create drug…

Solubility expressions and mechanism of solute solvent interactions
Solubility expressions and mechanism of solute solvent interactions Solubility of drugs plays an important role designing effective pharmaceutical formulations. Solubility refers to the phenomenon of a solute (such as a drug molecule) dissolving in a solvent (usually water) to create a homogeneous solution. Achieving the desired concentration of a drug in the systemic circulation is…
