    • Hydrolysis reactions can be utilized for prodrugs to release the active drug, for example, acetylsalicylic acid (aspirin) hydrolyzes to salicylic acid and acetic acid.
    • Temperature control is crucial for preventing rapid hydrolysis, as higher temperatures accelerate this reaction.
    • UV light exposure can cause photolysis and drug degradation, which can be prevented with light protection.
    • Drugs sensitive to light exposure include ascorbic acid, folic acid, nitroprusside, and phytonadione injection.
    • Other reactions that degrade drugs include isomerization, epimerization, and decarboxylation, which can be prevented by proper storage and handling.
    • Excipients such as buffers and preservatives help retain pH and prevent microbial growth, ensuring drug stability.
    • Light protection, tightly sealed packaging, and proper storage conditions are essential to prevent degradation from UV light exposure and heat.
    • Major excipients like binders, diluents, disintegrants, flavorings, lubricants, and preservatives serve different purposes in drug formulation.
    • Excipients like starches, cellulose, and alginates facilitate tablet disintegration and absorption in the small intestine.
    • Preservatives, such as alcohols and acids, are crucial for preventing microbial growth in most drug preparations, except for sterile or single-use preparations. Buffers help maintain pH within a certain range to improve stability and solubility.
