Compositions for promoting healing of bone fracture which contain as the active ingredient a phosphodiesterase (PDE) 4 inhibitor having an effect of inhibiting PDE4. In particular, medicinal compositions containing the PDE4 inhibitor and a biocompatible and biodegradable polymer which exert an excellent effect of promoting quick healing of bone fracture when processed into dosage forms adequate for topical administration to bone fracture sites, for example, microspherical preparations. These compositions are useful in treating bone fracture in, for example, aged persons, patients with diabetics and patients with osteoporosis which can be hardly repaired. |
