The in vitro disintegration time is the time taken by the film to undergo complete disintegration, to realize good patient compliance and acceptance of the oral thin film, one of the major quality aspects is the disintegration behavior of the films because a non-disintegration within a set time frame can result in choking or aspiration of the whole or parts of the film. CD Formulation provides different oral thin film in vitro disintegration testing methods to meet the different testing requirements of customers, thus promoting the development of oral thin film.

Oral thin films have gained significant attention in the pharmaceutical industry due to convenience, ease of administration, and potential for improved patient compliance, especially in populations like pediatrics and geriatrics. In vitro disintegration testing plays a crucial role in assessing the quality and performance of formulations.

In vitro disintegration testing is a necessary item in the quality control of oral dissolved film, but there is no universally recognized method at present. We usually use conventional disintegration methods, one-sided disintegration methods, double-sided disintegration methods, and in order to more closely match the situation in the human mouth, we have also developed a new disintegration device that is capable of mechanically dropping the test medium.
In Vitro Disintegration Testing | Detailed Information |
Disintegration Tester | Conventional disintegration method uses a disintegration tester, the medium is 1 L pH 6.8 phosphate buffer (PBS), the temperature is (37±0.5) ℃. The sample is allowed to rise and fall in the medium 29 to 32 times per minute, and the time required to completely pass through a 0.57 to 0.66 aperture sieve is recorded, which is the disintegration time. |
One-sided Disintegration Method | The one-sided disintegration method adopted a vibrating water bath device. One side of the sample is attached to a polyethylene plate with a glue stick and placed in a petri dish with 20 ml pH 6.8 PBS at a temperature of (37 ± 0.5) ℃. The shaking speed is 70 r·min-1, and the disintegration time of the sample is recorded when completely dissolved. |
Double-sided Disintegration Method | The double-sided disintegration method uses a vibrating water bath device, the samples are placed in a culture dish with 20 ml pH 6.8 PBS at a temperature of (37 ± 0.5) ℃, The shaking speed is 70 r·min-1, and record the disintegration time when the sample was completely dissolved. |
The New Disintegration Device | We develop a new oral dissolution test system with a sensor that automatically determines the disintegration time. When testing with this device, the test medium automatically drips from a fixed height at a constant flow rate. When the oral thin film disintegrates, the on-net and off-net approach each other, and the disintegration time is determined at that point in time. This device we developed can well simulate the oral situation, and the test results are closer to the situation when patients take the medicine. |

Results: In this study, four disintegration methods described in the literature were applied to characterize the disintegration behavior of these formulations. They were the petri dish, the slide frame, slide frame and ball (SFaB) method as well as the PharmaTest® disintegration tester equipped with a film sample holder. All methods show similar tendencies, at which the disintegration time proportionally increases with increasing dry film thicknesses. Reduced disintegration times were observed for ODFs containing insoluble MCC particles compared to their corresponding particle-free formulations.
