Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules01:18

Formulation and Manufacturing Process: Physical Attributes of Generic Tablets and Capsules

Bioequivalence in generic drugs, such as tablets and capsules, refers to their pharmaceutical equivalence to the brand-name counterparts. However, for therapeutic equivalence, manufacturers must also consider physical attributes like size, shape, and weight (FDA Guidance for Industry, December 2003). Discrepancies in these aspects could impact patient compliance and cause medication errors. For instance, swallowing difficulties, often experienced with larger tablets or capsules, can lead to...
Drug Delivery Systems: Different Types01:27

Drug Delivery Systems: Different Types

Conventional oral drug products, termed immediate-release (IR) formulations, are engineered to promptly release their active pharmaceutical ingredient (API) upon ingestion, typically in tablets or capsules. This rapid release often results in swift drug absorption and consequent pharmacodynamic effects, although the timing and intensity can vary depending on the drug's properties. Prodrugs within these formulations require metabolic conversion to activate their pharmacodynamic effects,...
In Vitro Drug Dissolution: Compendial Testing Models II01:09

In Vitro Drug Dissolution: Compendial Testing Models II

Various dissolution methods are utilized to assess a drug’s dissolution rate, including the flow-through cell, paddle-over-disk, cylinder, and reciprocating disk methods.The flow-through cell apparatus (USP (United States Pharmacopeia) method 4) comprises a reservoir for the dissolution medium and a pump that propels the medium through the cell containing the test sample. This method is crucial for assessing modified-release dosage forms with minimally soluble active ingredients, maintaining...
In Vitro Drug Dissolution: Compendial Testing Models I01:13

In Vitro Drug Dissolution: Compendial Testing Models I

Compendial dissolution methods are standardized procedures defined by pharmacopeias to evaluate the rate at which a drug dissolves in a specific medium. These methods ensure batch-to-batch consistency, enable quality control, and support the prediction of drug bioavailability. They are critical for both immediate and modified-release drug products.The apparatuses used for dissolution testing differ in their design and mechanical function, but all aim to simulate the physiological environment of...
Factors Influencing Drug Absorption: Pharmaceutical Parameters01:28

Factors Influencing Drug Absorption: Pharmaceutical Parameters

Solid dosage forms such as tablets and capsules undergo rigorous manufacturing processes to ensure stability and effectiveness. Their dissolution and absorption properties are influenced significantly by the choice of excipients (inactive ingredients that serve various roles in the formulation), and the methodology applied during production. The manufacturing parameters, such as compression force and granulation techniques, significantly affect dissolution rates. Elevated compression forces...
Drug Dissolution: Requirements and Profile Comparison01:14

Drug Dissolution: Requirements and Profile Comparison

The acceptance criteria for dissolution profile data are anchored in Q values, representing the percentage of drug dissolved within a specified period. This assessment unfolds in three stages:First Stage: The test passes if all six drug dosage units are equal to or greater than Q plus 5%; otherwise, the sample proceeds to the second stage.Second Stage: The average of twelve units must be equal to or greater than Q, with no unit falling below Q - 15% to pass; if not, it progresses to the final...

  • Pharmaceutical Technology
  • Materials Science
  • Mechanical Engineering

Background:

  • Tablet compression is a critical step in pharmaceutical manufacturing.
  • Conventional compression methods can have limitations in achieving desired tablet strength.
  • Optimizing tablet properties is essential for drug efficacy and patient compliance.

Purpose of the Study:

  • To compare the compression properties and characteristics of tablets produced by the oscillating-solid-die-ring-compressor (OSDRC) system versus conventional compression methods.
  • To evaluate the impact of the OSDRC system on tablet crushing strength and internal intensity.
  • To determine if the OSDRC system can improve tablet properties without formulation changes.

Main Methods:

  • Tablets were prepared using four distinct compression methods, including the OSDRC system and conventional techniques.
  • Key compression properties measured included force profiles, ejection force, stress relaxation, pressure transmission ratio, and internal tablet intensity.
  • Statistical analysis was performed to compare the properties across different compression methods.

Main Results:

  • Tablets produced using the OSDRC system exhibited the highest crushing strength.
  • While overall compression properties were comparable across methods, the internal intensity of OSDRC-compressed tablets was significantly higher.
  • The OSDRC method demonstrated superior performance in enhancing tablet structural integrity.

Conclusions:

  • The OSDRC system offers a superior method for achieving higher tablet crushing strength compared to conventional compression.
  • Tablet internal intensity is significantly improved with the OSDRC system.
  • The OSDRC system enables enhanced tablet strength without requiring modifications to the pharmaceutical formulation.
