Explanation:

The most common cause of chemical But overall, hydrolysis is the main culprit, especially in liquid drugs. in medicines is hydrolysis, especially for drugs with ester groups in liquid form. Other causes include:

• Oxidation – prevented by using antioxidants like ascorbic acid
• Photolysis – reduced by storing in amber or opaque containers
• Decarboxylation – affects drugs with carboxylic acid groups
• Racemization – affects optically active drugs, turning active forms into inactive mirror images

But overall, hydrolysis is the main culprit, especially in liquid drugs.
