Oral thin film is a novel drug delivery system that acts directly on the oral mucosa, sublingual, and other areas. Compared to traditional dosage forms, it excels in terms of enhanced bioavailability, high patient compliance, and the extension of the patent life of active pharmaceutical ingredients. Because the site of action is sensitive, special attention should be given to its stimulation studies. CD Formulation offers a range of scientific methods for evaluating the potential irritation or discomfort that may result from the use of oral thin films.
The active pharmaceutical ingredients, excipients and physical and chemical properties (such as pH value, etc.) of oral thin film may cause irritation, so the irritation study is one of the crucial indicators for the evaluation of the biological characteristics of oral thin film, provide a reference for clinical rescue measures, and ensure the safety and effectiveness of clinical drug use.
The purpose of the oral thin stimulation study is to fully evaluate the safety and tolerability of oral thin film. We usually establish animal experimental models to evaluate the irritation of thin film, and it usually involves controlled studies to assess the effect of thin film on the oral mucosa, ensuring that it does not cause irritation, inflammation or discomfort to the user. Our Irritation testing design includes:
We select experimental animals and establish experimental animal models for irritation studies based on the therapeutic purpose and the type of oral thin film.
The experimental scheme includes the animal design of the control group and the experimental group, the frequency of administration, the dosage, the observation after administration, etc.
Select appropriate statistical methods based on the experimental model and test method.

Issue Experimental Protocols: Discuss the client's specific requirements and issue detailed experimental protocols.
Sample Preparation: Pretreat samples according to testing requirements.
Establish Animal Models: Select appropriate experimental animals and establish animal models for irritation studies based on the therapeutic purpose and the type of oral thin film.
Observation of Irritation Reactions: Conduct the experiment by observing and recording the reactions of the experimental animals in detail.
Collection and Analysis of Data: Analyze and evaluate the collected data to assess the irritation caused by the oral thin film, and provide a comprehensive experimental report.

Results: This study was carried out to ensure the safety of film in the oral cavity. The hamster cheek pouch was selected as the study model. Images of the cheek pouch area were taken before and after placing the optimized bilayer films (Amlodipine besylate + Benazepril hydrochloride bilayer fast-dissolving oral film). The observation of images obtained of the cheek pouch area of the hamster before and after placing the bilayer film shows no irritation or redness.
