Adsorption, sorption, and humidity can all affect the dissolution of a drug by impacting the surface properties of the drug particles.
Adsorption refers to the attachment of molecules or ions to the surface of a solid substance. If the drug molecules adsorb onto the surface of the drug particles, it can decrease the surface area available for dissolution, leading to slower dissolution rates.
Sorption is a broader term that includes both adsorption and absorption. Sorption can involve the uptake of molecules into the bulk of a material, which can also impact the dissolution of a drug by altering the surface properties of the drug particles.
Humidity can also affect the dissolution of a drug by altering the surface properties of the drug particles. High humidity levels can lead to the formation of a moisture layer on the surface of the drug particles, which can impact the dissolution rate of the drug.
Overall, adsorption, sorption, and humidity can all impact the dissolution of a drug by altering the surface properties of the drug particles, which can affect the rate at which the drug dissolves in a solution.

Adsorption:
- Occurs when drug molecules adhere to the surface of solid excipients, such as fillers or binders.
- Reduces the amount of free drug available for dissolution.
Sorption:
- A broader term that encompasses both adsorption and absorption.
- Absorption involves drug molecules penetrating into the matrix of excipients, while adsorption involves surface binding.
- Both processes reduce drug dissolution by sequestering drug molecules.
Humidity:
- High humidity can increase drug dissolution by promoting the formation of amorphous forms of the drug, which are more soluble.
- Low humidity can decrease drug dissolution by favoring the formation of crystalline forms, which are less soluble.
Overall Effect on Dissolution:
Adsorption, sorption, and humidity can significantly influence drug dissolution by altering the amount of drug available for dissolution and the rate at which it dissolves.
High adsorption/sorption:
- Reduces drug dissolution.
- Inhibits bioavailability.
High humidity:
- May increase or decrease drug dissolution depending on the drug's physical form.
Low adsorption/sorption and optimal humidity:
- Promotes rapid and complete drug dissolution.
- Ensures maximum bioavailability.
- Occurs when drug molecules adhere to the surface of solid excipients, such as fillers or binders.
- Reduces the amount of free drug available for dissolution.
