Pentylenetetrazol, also known as pentylenetetrazole, leptazol, metrazol, pentetrazol (INN), pentamethylenetetrazol, Corazol, Cardiazol, Deumacard, or PTZ, is a drug formerly used as a circulatory and respiratory stimulant. High doses cause convulsions, as discovered by Hungarian-American neurologist and psychiatrist Ladislas J. Meduna in 1934. It has been used in convulsive therapy, and was found to be effective—primarily for depression—but side effects such as uncontrolled seizures were difficult to avoid. In 1939, pentylenetetrazol was replaced by electroconvulsive therapy, which is easier to administer, as the preferred method for inducing seizures in England's mental hospitals. In the US, its approval by the Food and Drug Administration was revoked in 1982. It is used in Italy as a car

  • Pentetrazol, INN, (Handelsname Cardiazol) ist ein bicyclisches Tetrazol-Derivat. Es wird als Kreislaufstimulans verwendet und regt die im Gehirn gelegenen Zentren der Atmung und der Herztätigkeit an. In hohen Dosen löst es Krämpfe aus, weshalb es früher auch in der Schocktherapie verwendet wurde. (de)
  • El pentilenotetrazol (también pentilentetrazol, Pentetrazol o su marca registrada Metrazol®) es un fármaco de acción estimulante del sistema nervioso central muy potente que se ha prescrito como analéptico para estimular el centro respiratorio, vagal y vasomotor del cerebro, para contrarrestar los efectos de los depresores y para incrementar el flujo sanguíneo cerebral, especialmente en pacientes geriátricos. En inglés, es conocido con el nombre de Pentylenetetrazol.​ (es)
  • Le pentylènetétrazole, également connu sous les noms des pentylènetétrazol, métrazol, pentétrazol, pentaméthylènetétrazol, cardiazol ou PTZ, est un médicament autrefois utilisé comme stimulant circulatoire et respiratoire. Le neurologue et psychiatre américano-hongrois Ladislas J. Meduna a découvert en 1934 que des doses élevées provoquaient des convulsions. Il a ainsi été utilisé dans ce sens pour provoquer des crises pharmaco-induites par injection intraveineuse dans le cadre d'électroconvulsivothérapies, mais n'a jamais été considéré comme efficace, des effets secondaires du type épilepsie étant difficile à éviter.Son autorisation par la Food and Drug Administration (FDA) a été annulée en 1982.

  • Il pentetrazolo, conosciuto anche come pentilenetetrazolo, metrazolo e pentametilenetetrazolo, è un farmaco che è stato utilizzato come stimolante circolatorio e respiratorio. Alti dosaggi possono causare, come scoperto da Ladislas Meduna nel 1934, attacchi convulsivi. La FDA ne ha revocato l'autorizzazione al commercio nel 1982, ma è tuttora in commercio in Italia con il nome di Cardiazol Paracodina, in combinazione con diidrocodeina, in questa formulazione è indicato come sedativo della tosse.

  • ペンテトラゾール(Pentetrazol;PTZ)またはペンチレンテトラゾール(Pentylenetetrazol)は、かつて循環器、呼吸器系の興奮剤として使われていた薬物である。1934年にハンガリー系アメリカ人の神経学者・精神科医のにより、高用量で痙攣を起こす事が発見されたことから痙攣療法にも使用された。これは主にうつ病に有効だと判明したが制御不能な痙攣発作等の副作用があり、1938年により実施が容易な電気痙攣療法が発明されるとすぐに取って代わられた。米国では、1982年に食品医薬品局による承認が取り消された。イタリアでは心肺機能賦活剤として、コデインと組み合わせて咳止め薬として使用されている。 (ja)
  • Пентилентетразол (коразол, метразол) — лекарственное средство, ранее использовавшееся при острых отравлениях снотворными и некоторыми наркотиками (барбитуратами, бензодиазепинами, опиоидами). (ru)
  • Pentylentetrazol, zvaný též metrazol, pentetrazol, pentamethylentetrazol, nebo zkratkou PTZ je heterocyklická organická chemická látka používaná jako léčivo stimulující dýchání a cirkulaci krve. Jak objevil v roce 1934 , maďarský neurolog žijící v USA, způsobuje tato látka ve vysokých dávkách křeče a záchvaty podobné epileptickým i u osob bez předešlé historie takových záchvatů a netrpících tudíž epilepsií (padoucnicí), jedná se tedy o tzv. – látku způsobující konvulze – křeče. Konvulzivní vlastnosti metrazolu bylo dříve využíváno k tzv. konvulzivní terapii psychických onemocnění, především byla terapie metrazolem účinná pro onemocnění depresivního charakteru. Tato terapie byla účinná a rychle odstraňovala příznaky, zejména právě depresivních onemocnění. Bylo však těžké a mnohdy nemožné p (cs)
