Summary for Patent: 9,884,050

Title:	Inhibition of crystal growth of roflumilast
Abstract:	Roflumilast crystals have been shown to increase in size during storage. The size of the roflumilast crystals can affect the bioavailability and efficacy of a pharmaceutical composition. The growth of roflumilast crystals can be inhibited during storage by including hexylene glycol in the composition. The resulting composition has improved bioavailability and efficacy and can be used to inhibit phosphodiesterase 4 in a patient in need of such treatment.
