Spoilage in Pharmaceutical Products can be categorized into three main types:
While all types are important, microbial spoilage is the focus here due to its direct impact on product safety.
1. Chemical Spoilage in Pharmaceutical Products
Definition:
Degradation of the active pharmaceutical ingredient (API) or excipients due to chemical reactions.
Examples:
Oxidation: API reacting with oxygen leading to loss of potency.
Hydrolysis: Breakdown of compounds due to reaction with water.
Photolysis: Degradation caused by exposure to light.
Impact:
Loss of efficacy, formation of toxic degradation products.
2.Physical Spoilage
Definition:
Changes in the physical properties of the product without altering chemical composition.
Examples:
Caking: Clumping of powders.
Phase Separation: In emulsions and suspensions.
Precipitation: In solutions due to temperature changes.
Impact:
Affects drug delivery, dosing accuracy, and patient acceptability.
3. Microbial Spoilage
Definition:
Deterioration of the product due to the growth and metabolic activities of microorganisms.
Examples:
Visible Mold Growth: On tablets or creams.
Bacterial Contamination: Leading to turbidity in solutions.
Gas Production: Causing containers to bulge.
Impact:
Potential infection risk, reduced efficacy, product recalls.
