From these, it appears that sildenafil is relatively stable in vehicles, with an acidic pH around 4 to 5. Sildenafil for oral suspension at 10 mg/mL (Revatio) is commercially available with a beyond-use date of 60 days after reconstitution. One study involved compounded sildenafil citrate in a citrate-buffered solution (0.1 M, pH 4) and either a syrup excipient (resulting in a suspension) or a sugar-free syrup excipient (resulting in a solution); both had pH values of approximately 4.2. Both the suspension and the solution were slightly pink and fruit-flavored. The suspension demonstrated stability for 91 days at both 4°C and 25°C; however, the solution was stable only for 30 days, possibly related to a nonredispersible sediment at the bottom of the container.3 A study by Nahata and colleagues that involved sildenafil citrate tablets (Revatio 20 mg) with a mixture of 1:1 Ora-Sweet and Ora-Plus at 2.5 mg/mL and pH 4.5-4.7 demonstrated stability of 91 days at both 4°C and 25°C.
