Clonidine and Potassium: what the published research says

PubMed indexes 6 records that name Clonidine and Potassium together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Clonidine and Potassium. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

6 studies naming Clonidine and Potassium.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Potassium disposition and neuroendocrine effects of propranolol, methyldopa and clonidine during dynamic exercise.

Clinical and experimental hypertension. Part A, Theory and practice · 1982 · PMID 6754155

Comparative StudyHuman subjects

“There were minor but significant changes in norepinephrine, renin and systolic pressure with multiple dose clonidine and methyldopa and in renin, heart rate and systolic and diastolic pressure with propranolol. Overall, the adrenergic responses, to exercise with methyldopa and propranolol are more biochemically altered than functionally impaired, yet the latter is related to dose and the underlying age and state of health of the group being studied.”

Lowenthal et al. · From the abstract

Names both Clonidine and Potassium in its title.

Involvement of potassium channels in spinal antinociceptions induced by fentanyl, clonidine and bethanechol in rats.

Japanese journal of pharmacology · 2001 · PMID 11829146

Animal study

“Also, each antinociception induced by fentanyl, clonidine or bethanechol was partially antagonized by both glibenclamide and charybdotoxin. These findings showed that activation of the K+ channel might enhance the antinociceptive effects of fentanyl, clonidine and bethanechol.”

Yamazumi et al. · From the abstract

Names both Clonidine and Potassium in its title.

Effects of moxonidine and clonidine on potassium excretion in Sprague-Dawley rats.

Pharmacological research · 1999 · PMID 10328993

Animal study

“Our results demonstrate that moxonidine and clonidine also increase renal K+ excretion in this animal model. K+and Na+ excretion show a parallel behaviour, indicating that the increased K+ excretion is mainly due to Na+ load in the tubular system.”

Hohage et al. · From the abstract

Names both Clonidine and Potassium in its title.

Clonidine inhibition of potassium-evoked release of glutamate and aspartate from rat cortical synaptosomes.

Brain research · 1991 · PMID 1814567

Animal study

“Rauwolscine, yohimbine and idazoxan counteracted the effects of clonidine on Glu and Asp overflow. The data suggest that the depolarization-evoked overflow of excitatory amino acids is regulated in an inhibitory fashion by alpha 2 adrenoceptors, which are located on the nerve terminals of Glu and Asp neurons in rat cortex.”

Kamisaki et al. · From the abstract

Names both Clonidine and Potassium in its title.

Clonidine activates membrane potassium conductance in myenteric neurones.

British journal of pharmacology · 1981 · PMID 6274464

Animal study

“Conversely, clonidine was almost ineffective in elevated calcium concentrations. This was true for both the hyperpolarization and the conductance increase.6 It is suggested that clonidine activates a potassium conductance by causing an elevation in the free intracellular calcium concentration.7 Clonidine reversibly depressed the amplitude of the nicotinic fast excitatory postsynaptic potential and the noncholinergic slow excitatory postsynaptic potential.8 All the effects of…”

Morita et al. · From the abstract

Names both Clonidine and Potassium in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Clonidine, Potassium, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
