Titration is extremely important in the pharmaceutical industry because it ensures accuracy, safety, and quality of drugs. Here are the key real-world applications:
1. Determination of Drug Potency
- Used to measure the exact concentration of active ingredients in medicines.
- Ensures that each dose contains the correct amount of drug.
- Example: Determining the exact amount of aspirin in a tablet.
2. Quality Control of Raw Materials
- Checks the purity of raw chemicals used in drug manufacturing.
- Detects impurities that could affect drug safety.
- Example: Testing the purity of hydrochloric acid or sodium hydroxide used in production.
3. Assay of Vitamins and Nutrients
- Determines the exact content of vitamins in pharmaceutical formulations.
- Example: Vitamin C tablets are assayed using redox titration with iodine solution.
4. Buffer and pH Control
- Ensures proper pH levels in drugs, especially in injectables and ophthalmic solutions.
- Maintains stability and effectiveness of medicines.
- Example: Titration is used to adjust pH in intravenous solutions.
5. Analysis of Pharmaceutical Compounds
- Quantifies compounds that react with acids, bases, or oxidizing/reducing agents.
- Example: Determining the amount of hydrochlorothiazide (diuretic drug) using acid-base titration.
6. Determination of Impurities
- Identifies unwanted reactive substances in drugs.
- Helps in maintaining regulatory compliance.
- Example: Detecting unreacted raw materials or degradation products.
7. Monitoring Stability of Drugs
- Measures how drugs degrade over time under storage conditions.
- Ensures safety and shelf life.
- Example: Titration can detect decomposition products in vitamin C solutions.
Summary:
Titration in pharmaceuticals is all about accuracy, safety, and quality assurance, whether it’s measuring drug content, checking purity, or controlling pH.
