Over 800,000 Americans abuse the psychomotor stimulant, methamphetamine, yet its abuse is without an approved medication. Methamphetamine induces hypermotor activity, and sensitization to this effect is suggested to represent aspects of the addiction process.

Phosphodiesterase-4 (PDE-4) is a cyclic adenosine monophosphate-specific enzyme involved in various inflammatory diseases. We studied its role in and the effect of ibudilast, which predominantly blocks PDE-4, on rat cerebral aneurysms. Cerebral aneurysms were induced at the anterior cerebral artery-olfactory
