Study Notes
Quality Control in Pharmaceutical Manufacturing: Solid Dosage Forms
- Quality control (QC) is crucial in pharmaceutical manufacturing. It ensures the safety, efficacy, and consistency of medicinal products.
- This presentation focuses on QC procedures for solid dosage forms, specifically tablets.
- Tablets are a prevalent dosage form in the pharmaceutical industry.
Understanding Quality Control in Pharmaceutical Manufacturing
- Quality Assurance (QA) aims to prevent product defects. It creates a system for ensuring quality throughout the manufacturing process.
- QC is part of QA, focusing on the direct testing and monitoring of products.
- QC ensures that manufactured products meet predefined standards. It involves sampling, testing, documentation, and analysis to identify deviations.
Solid Dosage Forms
- Tablets: Made by compressing a mix of active pharmaceutical ingredients (APIs) and excipients. They come in various forms (buccal, sublingual, chewable, enteric-coated, effervescent).
- Capsules: Enclose APIs and excipients in a shell (either powder or granule form). Two types: hard-shelled (contains powder) and soft-shelled (contains oil).
- Granules: Dry preparations with a definite particle size, made from APIs and suitable excipients.
- Lozenges: Hard medicines that dissolve slowly in the mouth, prolonging the effects of the medicine at the site of action (e.g., antiseptic, antitussive).
- Suppositories: Solid dosage forms applied to the rectum. Composed of an active ingredient in a suppository base.
Quality Control of Tablets: A Comprehensive Approach
- Weight Uniformity: Ensures each tablet contains the correct dosage of active ingredient, ensuring consistent therapeutic efficacy.
- Content Uniformity: Determines the accuracy of active ingredient content in individual tablets, ensuring consistent dosage.
- Dissolution: Evaluates how readily the active ingredient dissolves from the tablet, impacting bioavailability and effectiveness in the body.
- Mechanical Strength: Measures the tablet's hardness and resistance to breakage during handling and manufacturing.
Weight Uniformity Test: Ensuring Consistent Dosage
- Sampling: Randomly select 20 tablets from the batch.
- Individual Weighing: Weigh each tablet accurately.
- Deviation Calculation: Calculate percentage deviation from the average weight.
- Acceptance Criteria: Compare deviations to established standards to ensure compliance.
Weight Uniformity Test: Aspacid 75 mg
- Sampling: Randomly select 20 tablets from the production run.
- Calculate individual and average weighing: Sum of the weights divided by 20.
- Deviation calculation: ((Individual weight-Average Weight) / Average Weight)*100
Acceptance Criteria
- Tablets weighing 80 mg or less, deviations should not exceed ±10%.
- Tablets between 80-250 mg, deviations should not exceed ±7.5%.
- Tablets over 250 mg, deviations should not exceed ±5%.
- The test is considered passed if not more than two tablets deviate beyond the acceptable limit, and none exceeds double the limit.
Causes for Weight Variations
- Size and distribution of granules (being compressed).
- Poor flow and high-speed turret speed (incomplete filling).
- Poor mixing (uneven distribution of lubricants and glidants).
- Variability in lower punch length (inconsistent fill).
Content Uniformity Test: Method
- Sampling: Randomly select 30 tablets from batch (for tablets less than or equal to 40 mg).
- Initial Assay: Determine the average content of active ingredient in 10 tablets by analysis.
- Acceptance Criteria: Individual tablet content must fall within ± 15% for content less than or equal to 40 mg and between 75% to 125% range for any individual to comply with the test.
- Further Assay: Assay the remaining 20 tablets for a full batch uniformity analysis.
Dissolution Test: Evaluating Active Ingredient Release
- Purpose: Assesses how rapidly the active ingredient dissolves.
- Methodology: Immersing tablets in a simulated fluid at controlled temperatures and stirring speeds.
- Acceptance Criteria: Ensures the active ingredient dissolves within specified timeframes and extent.
Mechanical Strength: Ensuring Tablet Integrity
- Hardness Test: Evaluates tablet resistance to crushing and breakage.
- Friability Test: Measures tablet's resistance to abrasion during handling and transport.
Visual Inspection: Ensuring Tablet Appearance and Uniformity
- Appearance: Checks for discoloration, defects, or inconsistencies.
- Shape: Verifies consistency with specifications, free from distortions.
- Size and Dimensions: Measures diameter and thickness using instruments (e.g., vernier calipers) to check uniformity within the batch.
In-Process Control: Maintaining Quality Throughout Production
- Continuous monitoring and adjustment of critical parameters during manufacturing.
- Helps minimize manufacturing deviations and ensure product consistency.
Essential Instruments for Quality Control
- Analytical Balances: Precision measurement of weights.
- Dissolution Apparatus: Testing how quickly the active ingredients dissolve.
- Disintegration Tester: Assessment of whether the tablet breaks into smaller particles.
- Hardness Tester: Measures the hardness of the tablets.
- Friability Tester: Measures the resistance of the tablets to abrasion.
- Vernier Caliper or Micrometer: Measuring tablets' dimensions for uniformity.
- UV-Vis Spectrophotometer: Instrumental analysis of the active ingredient or other components being assessed.
