Abstract :
[en] Evaluated the interaction of either gaboxadol HCl (THIP) or muscimol, both gamma-aminobutyric acid (GABA) type A agonists, with indirect-acting dopamine agonists (DAGs) methylphenidate, (+)-amphetamine, metamphetamine, amfonelic acid, indatraline, nomifensine, diclofensine, mazindol, and GBR 12935 and with direct-acting DAGs WIN 35,428, bupropion, GBR 12909, and cocaine. 1,832 male C57BL/6J mice were given either with saline or 1 of the doses of THIP or muscimol before an injection of a dopamine agonist. Gnawing on corrugated packing paper was measured. Results showed that: (1) indirect- but not direct-acting DAGs induced gnawing, (2) gnawing induced by indirect-acting DAGs GBR 12935, nomifensine and mazindol was potentiated in mice in which GABA type A receptors were stimulated either by THIP or muscimol, and (3) indirect DAGs had a differential sensitivity to the effects of THIP and muscimol.
