Clinically Relevant Drug Product Specifications: Methods of Establishment

Clinically Relevant Drug Product Specifications: Methods of Establishment

Product specifications define the acceptable quality of a pharmaceutical product by ensuring identity, purity, potency, and strength. These specifications serve as benchmarks during development, manufacturing, and post-approval quality control. Clinically relevant specifications are particularly important because they directly relate to a drug's safety and efficacy in clinical use.Dissolution studies are critical biopharmaceutic tools that link in vitro behavior to in vivo performance. They...

Preclinical Development: Overview

Preclinical Development: Overview

Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...

Bioavailability Study Design: Single Versus Multiple Dose Studies

Bioavailability Study Design: Single Versus Multiple Dose Studies

Bioavailability studies are essential for understanding how a drug is absorbed, distributed, metabolized, and excreted in the body. These studies assess the extent and rate at which the active pharmaceutical agent becomes available at the site of action. The design of bioavailability studies can involve single-dose or multiple-dose regimens, each with distinct advantages and limitations.Single-dose studies are the preferred approach due to their simplicity and reduced drug exposure for...

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...

Bioavailability Enhancement: Determination and Conceptual Approaches in Overcoming Bioavailability Problems

Bioavailability Enhancement: Determination and Conceptual Approaches in Overcoming Bioavailability Problems

Bioavailability is a critical pharmacological concept that measures the extent and rate at which an active drug ingredient or therapeutic moiety enters the systemic circulation, remaining unchanged. It's a pivotal factor in determining a drug's efficacy and safety.The Biopharmaceutics Classification System (BCS) plays an essential role in drug development by categorizing drugs into four classes based on their solubility and permeability. This classification aids in understanding drug absorption...

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

Area of Science:

Nutrition Science
Public Health Research
Dietary Assessment Methods

Background:

Accurate dietary intake data is essential for population-based health studies.
Existing methods for collecting dietary supplement use data require systematic evaluation.
The Supplement Reporting (SURE) study addressed the need for improved dietary supplement data collection accuracy.

Purpose of the Study:

To systematically examine the accuracy of various methods for collecting dietary supplement use data.
To develop and expand a comprehensive supplement composition database for accurate intake quantification.
To compare different data collection methods for dietary supplements in population studies.

Main Methods:

Conducted the SURE study with 444 participants in Hawaii and Los Angeles (2005-2007).
Compared data collection methods: supplement inventory, recall, daily diary, and frequency questionnaire.
Developed an extensive supplement composition table (SCT) by creating approximately 1800 new codes, including 211 default codes.

Main Results:

The SURE study systematically evaluated dietary supplement data collection methods.
An expanded supplement composition table (SCT) was created, including ~130 nutrients and 870 other components.
Significant effort was invested in developing a comprehensive database to quantify supplement intake.

Conclusions:

Maintaining a comprehensive supplement composition database is crucial for accurate intake quantification.
The SURE study highlighted the importance of systematic evaluation in dietary assessment.
Future work will incorporate analytic values from the USDA to enhance the SCT.
