奎尼丁与胺碘酮合用可引起()

A.从组织结合部位置换下来

B.奎尼丁血药浓度下降

C.奎尼丁血药浓度升高

D.胺碘酮血药浓度升高

E.药物代谢增加

答案

参考答案:C

解析::奎尼丁与胺碘酮合用时,胺碘酮可抑制奎尼丁的代谢,提高奎尼丁的血药浓度,会出现严重的心律失常;奎尼丁与地高辛合用时,奎尼丁能使地高辛血药浓度升高,提高的程度与奎尼丁的用量有关,由于奎尼丁能从组织结合处置换地高辛,可引起中毒,合用时应减少地高辛的用量;苯妥英钠为肝药酶诱导剂,可加速奎尼丁的代谢,使血药浓度降低。

      LONDON, England (CNN)—The youngest person to sail solo around the world returned home

Thursday from his 30,000-mile, 282-day ocean journey.

      Mike Perham, 17, sailed into Lizard Point in Cornwall, the southernmost point in Britain, at 9:47 a.m.,

his race team said.

      "It feels absolutely brilliant," Mike told CNN by phone hours before crossing the finish line. "I'm

really, really excited to be going across the line at last. It doesn't feel like long since I crossed it first."

      Mike set off on his round-the-world trip on November 18, 2008. He has been sailing his yacht

single-handedly, though a support team has been sailing next to him along the way.

      The teen has now achieved the title of Youngest Sailor to Circumnavigate the Globe Solo, according

to the Guinness World Records.

      Mike learned how to sail when he was seven years old from his father, Peter and at age 14, he sailed

across the Atlantic alone.

      The teenager's school-which Mike describes as"highly supportive" of his trip-has redesigned his

coursework to fit in with his trip. It also gave him some coursework to do during"quiet moments,"

according to Mike's Web site.

     There haven't been many of those quiet moments. Repeated autopilot failures forced him to stop for

repairs in Portugal, the Canary Islands, South Africa, and twice in Australia, according to his Web site.

     Bad weather in the Southern Ocean-between Australia and Antarctica-forced Mike to battle 50ft waves

and 57 mph winds. He said at one point, a "freak wave" picked up the boat and turned it on its side.

     "My feet were on the ceiling at the time," he told CNN. "That was a really hairy moment, and I was

certainly thinking, 'Why am I here?' But we took the sails off and the day after I thought, 'This is brilliant!'"

      Mike describes his father as his biggest hero, always supportive of what he wanted to achieve. Peter

Perham said he wasn't too worried about his son facing dangerous situations at sea, as long as he knew

what to do and stayed safe.
