Which drug is benserazide usually co-administered with?
['The present study utilizes in vivo amperometry to investigate the impact from unilateral 6-hydroxydopamine lesions and l-DOPA (4 mg/kg, including benserazide 15 mg/kg) -induced dyskinetic behavior on striatal basal extracellular glutamate concentration and potassium-evoked glutamate release in urethane-anesthetized rats. ', 'Co-administration of L-Dopa with peripheral DDC inhibitors (carbidopa or benserazide) is the most effective symptomatic treatment for PD.', 'In experiment 1, l-DOPA-primed rats were pre-treated with Vehicle (0.9% NaCl), various doses of the partial 5-HT(1A) agonist, buspirone (0.25, 1.0 or 2.5 mg/kg, ip) or buspirone (2.5 mg/kg, ip)+the 5-HT(1A) antagonist, WAY100635 (0.5 mg/kg, ip) 5 min prior to l-DOPA (12 mg/kg+15 mg/kg benserazide, ip). R', 'L-DOPA induced hyperalgesia occurred after conversion to dopamine because co-administration of benserazide, a DOPA decarboxylase inhibitor, completely abolished the L-DOPA-induced hyperalgesia. ', 'First, animals were treated with levodopa (50 mg/kg with benserazide 12.5 mg/kg, twice daily), intraperitoneally (i.p.) for 22 days. ', 'Chronic L-DOPA-treated rats received the D1 receptor antagonist SCH23390 (0.01, 0.1, and 1.0 mg/kg; i.p.), the D2 receptor antagonist Eticlopride (0.01, 0.1, and 1.0 mg/kg; i.p.), a mixture of both antagonists (0.01, 0.1, 1.0 mg/kg each; i.p.), or vehicle 30 min prior to L-DOPA (6 mg/kg; i.p.)+Benserazide (15 mg/kg; i.p.).', 'Nociceptive behaviors in mice after an intrathecal (i.t.) administration of substance P were evaluated. L-DOPA (i.t.) dose-dependently attenuated the substance P-induced nociceptive behaviors. Co-administration of benserazide (i.t.), a DOPA decarboxylase inhibitor, abolished the antinociceptive effect of L-DOPA.', 'They were injected subcutaneously (s.c.) with L-DOPA methyl ester (125 mg per animal) plus benserazide (50 mg per animal; L-DOPA/benserazide) alone or in combination with (-)-OSU6162 (1.0, 3.0, 6.0 or 10 mg/kg, s.c.)', 'They were injected subcutaneously (s.c.) with L-Dopa methyl ester (125 mg per animal) plus benserazide (50 mg per animal; L-Dopa/benserazide) alone or in combination with JL-18 (at the doses of 0.1, 0.3, or 0.9 mg/kg, s.c.).', 'The administration of L-dopa (20 and 60 mg/kg p.o.) + benserazide (15 mg/kg p.o.) resulted in dose-dependent increase of dialysate levels of L-dopa and 3-O-methyl-DOPA. Tolcapone (30 mg/kg p.o.), given as adjunct to both doses of L-dopa, markedly enhanced the elevation or extracellular L-dopa, while it completely prevented the formation of 3-O-methyl-DOPA. In another experiment, the administration of L-dopa + benserazide (30 + 15 mg/kg p.o.) resulted in increased extracellular levels of dopamine, DOPAC, HVA and 3-methoxytyramine.', 'In healthy subjects and in patients with parkinsonism plasma ALAAD level fell after administration of L-dopa + benserazide, but returned to previous levels within 90 min.', 'In a cross-sectional study blood was obtained, 2 h after dosing, from 104 patients with idiopathic parkinsonism, divided into four groups: no L-dopa treatment (group 1), L-dopa alone (group 2), L-dopa + benserazide (Madopar) (group 3) and L-dopa + carbidopa (Sinemet) (group 4).']
