Exploring paediatric oral suspension development: Challenges, requirements, and formulation advancements

Area of Science:

• Pharmaceutical Sciences
• Paediatric Drug Delivery

Background:

• Oral suspensions are preferred for paediatric patients due to difficulties with solid dosage forms.
• Challenges include swallowing issues, bitter taste, poor bioavailability, and physiological variations in children.
• Ensuring successful treatment requires safe and effective paediatric oral suspensions.

Purpose of the Study:

• To review essential aspects of paediatric oral suspension development.
• To analyze considerations for selecting safe and effective excipients and preservatives.
• To address challenges in formulating stable, age-appropriate paediatric suspensions.

Main Methods:

• Literature review focusing on paediatric oral suspension formulation.
• Analysis of excipient and preservative selection criteria.
• Examination of factors influencing drug release and bioavailability in paediatric populations.

Main Results:

• Excipient selection is critical for safety, efficacy, and stability of paediatric oral suspensions.
• Drug release kinetics significantly impact oral absorption and bioavailability, especially for BCS class II drugs.
• Formulating a single, stable suspension for the diverse paediatric age group presents formulation challenges.

Conclusions:

• Careful selection of excipients and preservatives is paramount for paediatric oral suspension development.
• Optimizing drug release profiles can enhance bioavailability and minimize adverse effects in children.
• Further research is needed to address formulation stability and age-specific pharmacokinetic considerations.
