A recently granted patent (Publication Number: US11850306B2) discloses a freeze-dried medical aerogel comprising nanofibrillar cellulose, a single active pharmaceutical ingredient selected from a wide range including antibiotics, pain relievers, vitamins, and medication for various diseases, polyethylene glycol, and trehalose. The aerogel has a moisture content of 10% or less and the components are present in specific weight ratios. The active pharmaceutical ingredient content in the aerogel ranges from 0.1% to 65% (w/w).

Furthermore, the patent details the method of obtaining the freeze-dried medical aerogel, which involves providing a hydrogel with nanofibrillar cellulose, polyethylene glycol, and trehalose, mixing them, and freeze-drying the mixture. The nanofibrillar cellulose plays a crucial role as the only polymeric gel-forming material in the aerogel, with specific characteristics such as length exceeding 1 µm, a diameter smaller than 200 nm, and specific viscosity and yield stress values. The active pharmaceutical ingredient can vary and includes well-known medications like metronidazole, lidocaine, and tamoxifen, among others. This innovative aerogel formulation opens up possibilities for controlled drug delivery systems and medical applications due to its unique composition and properties outlined in the patent claims.
