[Bioavailability of ampicillin preparations for internal use]
Antibiotiki
|January 1, 1980
Summary
This study found no significant differences in ampicillin absorption rates between different dosage forms. The rate of ampicillin dissolving in solution did not correlate with how much antibiotic was absorbed by the body.
Area of Science:
- Pharmacokinetics
- Drug formulation
- Antibiotic absorption
Context:
- Evaluating ampicillin bioavailability is crucial for effective antibiotic therapy.
- Different ampicillin dosage forms (trihydrate, anhydrous, capsules, tablets) may exhibit varied absorption profiles.
- Understanding dissolution rates is important for predicting drug performance.
Purpose:
- To compare the bioavailability of various ampicillin dosage forms.
- To investigate the relationship between dissolution rate and in vivo absorption of ampicillin.
- To determine if ampicillin trihydrate and anhydrous forms differ in absorption.
Summary:
- No significant differences in ampicillin absorption levels or rates were observed between ampicillin trihydrate and anhydrous ampicillin capsules, or ampicillin trihydrate tablets.
- Significant variations in the rate of ampicillin dissolution from different dosage forms were detected using the rotating basket method.
- A lack of correlation was found between the rate of ampicillin transfer into solution and its in vivo absorption.
Impact:
- Findings suggest that different ampicillin formulations may be interchangeable regarding bioavailability.
- The study highlights that in vitro dissolution testing may not accurately predict in vivo ampicillin absorption.
- Provides valuable data for pharmaceutical development and clinical prescribing of ampicillin.
