Are you working with complex dosage forms?

Emerging formulations and novel drug delivery technologies require a revised approach to in-vitro drug release testing. Due to the complex nature of these formulations, extensive testing and development are crucial to ensure patient safety and efficacy.

Long Acting Injectables (LAI) such as microspheres, liposomes, injectable suspensions, and other complex dosage forms like ophthalmic suspensions, coated medical devices (e.g., stents), creams, gels, and implants are becoming increasingly common. They offer unique advantages such as sustained drug release, targeted delivery, improved bioavailability, and reduced side effects. However, their complex nature requires extensive testing and development to ensure safety, efficacy, and regulatory compliance.
