Potency

Camphor: Strong Aromatic Odour On Burning 

Camphors burns without leaving ash or residue

Camphor: Solid ketone obtained from volatile oil of Cinnamomum Camphora

Camphor: Physical Degradation

Camphor Degradation: Loss Of Volatile Components 

Volatile contents lost at ambient temperature through vaporization

Volatile Components are present in 

Alcohol, Ether, Iodine, Volatile Oils, Camphor and Menthol

Loss Of Volatile Components Depends Solely On Potency

Potency: Amount Of Drug required to produce a response

Pharmaceutical Degradation Affects The Potency Of The Drug

Physical Degradation

Example:  Vitamin Tablets

Expired Vitamin Tablets/Capsules = Change In Drug Release

Expired Vitamin Tablets dont have the expected content in them

Other Preparations

Expired Suspension: Loss Of Drug Content Uniformity

Expired Emulsions: Loss of drug content uniformity in doses

Expired Oinments: Loss of drug content uniformity

Apart From Physical There Is Chemical Degradation

Microbial Degradation

Pharmaceuticals

Short term application/effects
