A recently granted patent (Publication Number: US11844858B2) discloses an aqueous ophthalmic solution containing 1% of phentolamine or its salt, 1% to 6% of a polyol compound with a molecular weight less than 250 g/mol, a buffer in the range of 0.1 mM to 10 mM, water, and optionally alkali metal halides. The solution is characterized by a pH between 4.0 to 7.5. Specific embodiments include the use of mannitol as the polyol compound and sodium acetate as the buffer, with the pH falling within the range of 4.5 to 6.0.
Furthermore, the patent claims another aqueous ophthalmic solution comprising 1% phentolamine mesylate, 1% to 6% mannitol, a buffer in the range of 0.1 mM to 10 mM, water, and optionally alkali metal halides. This solution also maintains a pH between 4.5 to 6.0, with specific concentrations of mannitol at 4% and the buffer at 3 mM. The inclusion of sodium acetate as the buffer component is highlighted in several claims. Additionally, the patent specifies that less than 2% of the phentolamine mesylate should degrade after storage at 25°C for 24 weeks, ensuring the stability of the solution over time.
