Взаимодействия с лекарства

What laboratory studies, small human studies and case reports actually show about kava interactions.

Кратко и ясно

Kava can interact with medicines and other central nervous system depressants. Laboratory findings show several possible CYP inhibitions, but small human studies do not confirm one uniform pattern across all enzymes. Alcohol and sedatives in particular should not be self-combined; regular medication warrants individual review.

Системата на цитохром P450

Системата на цитохром P450 (CYP450) е семейство ензими в черния дроб, отговорни за метаболизма на повечето лекарства. Когато вещество инхибира тези ензими, други вещества се метаболизират по-бавно – тяхното действие и странични ефекти могат да се усилят.

Защо е важно?

Many medicines are metabolised by CYP enzymes. An in-vitro finding does not automatically mean clinically relevant inhibition in humans. Preparation, dose, duration and the medicine's therapeutic window determine practical relevance.

Кои ензими се инхибират?

Mathews et al. (2002) tested kava extract and individual kavalactones in human liver microsomes and found inhibition of several CYP enzymes. These are in-vitro findings, not clinical inhibition ratings in humans:

ЕнзимСтепен на инхибиранеВажни субстрати (примери)
CYP1A2In-vitro findingКофеин, Теофилин, Клозапин, Оланзапин
CYP2C9In-vitro findingВарфарин, Фенитоин, НСПВС (Ибупрофен)
CYP2C19In-vitro findingОмепразол, Диазепам, Клопидогрел
CYP2D6In-vitro findingКодеин, Трамадол, много антидепресанти
CYP3A4In-vitro findingБензодиазепини, Статини, много антибиотици

Клинично значение

Russmann et al. (2005) reported reduced CYP1A2 activity in chronic users of traditional aqueous kava. Gurley et al. (2005; 12 healthy volunteers, 28 days, 138 mg kavalactones/day), by contrast, found reduced CYP2E1 but no significant change in CYP1A2, CYP2D6 or CYP3A4/5. The human findings are small and preparation- and consumption-dependent, so they cannot predict every medicine interaction.

Комбинации с висок риск

The following combinations should be avoided or medically reviewed in advance. Reasons differ: some involve additive CNS effects or case reports, while others have only mechanistic signals and no controlled combination trials.

⚠ Алкохол

Risiko: AVOID

Concurrent use of kava and alcohol is not recommended:

  • 1.Additive CNS effects: Drowsiness, slower reactions and impaired coordination may increase.
  • 2.Liver risk not quantified: A combined liver risk has not been quantified reliably; the combination is avoided because of this uncertainty.
  • 3.Unpredictable intensity: Product, amount, drinking pattern and individual sensitivity make effects difficult to predict.

Do not use kava and alcohol together. The main practical reason is possible additive impairment of attention, reaction and coordination; the size of any additional liver risk is not reliably established.

⚠ Бензодиазепини и сънотворни

Risiko: PROFESSIONAL REVIEW

Do not combine benzodiazepines or Z-drugs with kava without medical review:

  • •Additive sedation: Drowsiness and psychomotor impairment may increase.
  • •CNS depression: Clinically relevant potentiation is possible; controlled combination trials are lacking.
  • •Interpret CYP findings: CYP3A4 inhibition was observed in vitro but not consistently confirmed in small human studies.

Случай на доклад: Almeida & Grimsley (1996) described a semicomatose state in a 54-year-old man after reported kava and alprazolam use. A single case report is a warning signal but does not establish mechanism or frequency.

⚠ Антипсихотици

Risiko: PROFESSIONAL REVIEW

Individual medical review is appropriate before kava use with antipsychotics:

  • •Sedation: Additive drowsiness or psychomotor impairment is possible.
  • •Case reports: Individual reports describe movement disorders; frequency and causality are unclear.
  • •CYP findings: Laboratory inhibition does not reliably predict the level of a specific medicine.

⚠ Антикоагуланти (разредители на кръвта)

Risiko: PROFESSIONAL REVIEW

Warfarin, phenprocoumon and other anticoagulants require professional review because of their narrow therapeutic window:

  • •Mechanistic signal: CYP2C9 inhibition was observed in vitro; a clinical kava-warfarin interaction has not been established in controlled studies.
  • •Monitor INR: Changes in co-used products should be coordinated with the treating clinician.
  • •Bleeding risk: The baseline risk of anticoagulation makes self-testing inappropriate.

Use kava with anticoagulation only after individual medical review.

Комбинации с умерен риск

Следните комбинации изискват внимание и трябва да се извършват само след консултация с лекар. Може да се наложи корекция на дозата.

Антидепресанти

Risiko: PROFESSIONAL REVIEW

SSRIs (Флуоксетин, Сертралин, Пароксетин и др.):
  • • Pharmacokinetic interactions may occur depending on the product but are not clinically established as a class
  • • Serotonin syndrome from kava is not established as a typical clinical effect
  • • Additive drowsiness or dizziness are possible
SNRIs (Венлафаксин, Дулоксетин):
  • • Direct clinical combination data are limited
  • • Review co-medication individually rather than inferring from in-vitro CYP data
MAO инхибитори:
  • • MAO-B effects of individual kavalactones have been studied preclinically
  • • Pawa et al. (2026) found MAO-A inhibition by flavokawain A in an in-vitro enzyme assay; humans and combination with MAO inhibitors were not studied
  • • Do not self-combine with MAO inhibitors because medicine interactions can be serious
  • • Obtain medical review before use

Антиконвулсанти (антиепилептици)

Risiko: PROFESSIONAL REVIEW

Фенитоин, Карбамазепин, Вальпроат и други антиконвулсанти:

  • •Pharmacokinetics: Altered levels are possible but cannot be predicted reliably for individual combinations.
  • •CNS effects: Additive drowsiness or coordination problems are possible.
  • •Seizure control: Changes in co-used products belong under professional supervision.

При епилепсия Кава трябва да се използва само под медицински контрол.

Лекарства за Паркинсон

Risiko: PROFESSIONAL REVIEW

Леводопа и допаминови агонисти:

  • •Mechanism unclear: Blanket clinical dopamine antagonism by kava has not been established.
  • •Case reports: Individual reports describe worsening Parkinson symptoms; medical review is therefore needed.

With Parkinson's disease or related medication, use kava only after medical review.

Хепатотоксични лекарства

Risiko: УМЕРЕН

Лекарства с известно хепатотоксично потенциал:

  • •Парацетамол/Ацетаминофен: Особено проблематично при по-високи дози
  • •Статини: Аторвастатин, Симвастатин и др. (CYP3A4 субстрати)
  • •Метотрексат: Имуносупресор с хепатотоксичност
  • •Изониазид: Лекарство за туберкулоза

Additional liver risk is plausible but not quantified for every combination. Potentially hepatotoxic medication requires individual medical review.
