Multilayer NSAID Triptan Tablets Segregate Dissolution

The patent divides the single dosage form into multiple layers, with each layer containing a different active ingredient (triptan or NSAID). This segmentation prevents direct interaction between the two drugs while maintaining them in a single convenient dosage form, thereby preserving drug stability and dissolution properties while improving patient compliance.

By segmenting the dosage form into separate layers for triptans and NSAIDs, the patent eliminates the formation of a gel-like matrix that would otherwise slow dissolution. Each layer dissolves independently at its own optimal rate, maintaining fast dissolution speed while preserving the convenience of a single dosage form.

The patent uses layer compression technology, which is a well-established pharmaceutical manufacturing technique. Each layer is compressed separately and then bonded together, a process that adds minimal complexity to existing manufacturing workflows while achieving the desired drug separation and stability.

The multilayer structure creates distinct zones for each drug, allowing independent dissolution and absorption kinetics. This segmentation ensures reliable pharmacokinetic profiles by preventing drug interactions while maintaining a relatively simple tablet geometry that is easy to administer.
