Does Ketamine Lower Blood Pressure

Initially, ketamine was used as anesthesia by doctors, but later, research led to changes in its usage and dosage.
Recent research shows that ketamine is also effective in reducing depression and pain, which is quite remarkable.
However, the question comes up: does ketamine lower blood pressure?
Below, we’ll discuss its usage and dosage; including the extent to which it can help.
To get more details about the ways to reduce anxiety and depression, please reach out to Goodness Psychiatry.

What is Ketamine?

Ketamine is used as an anesthetic for certain medical procedures.
A patient could appear awake, but not feel or remember the procedure due to a depressed level of consciousness.
At lower, sub-anesthetic doses, ketamine has shown promise for treating depression and PTSD by resetting overactive areas of the brain.
It can provide rapid anti-depressant effects.
Ketamine binds to NMDA receptors in the brain, inhibiting glutamate.
This produces a dissociative, hallucinogenic state, sometimes likened to a dream-like trance.
However, low medical doses under supervision carry less addiction risk, and side effects are usually manageable.
Strict guidelines and clinical oversight are important for safety and effectiveness.

Ketamine and Blood Pressure

Does ketamine affect blood pressure? Each medicine has some effect, regardless of its dose or quantity.
The effects of ketamine on blood pressure are similar.
Ketamine can potentially increase blood pressure both during and briefly after administration.
This is a physiological effect of the drug.
The degree of blood pressure increase depends on the dose and route of administration.
Higher doses and IV administration produce larger increases.
Furthermore, for medical or therapeutic use, ketamine is usually administered in a clinical setting where blood pressure can be monitored.
This allows any increases to be managed safely.
Thus, ketamine-induced blood pressure changes are usually not severe or long-lasting with proper medical use and screening.
However, ongoing monitoring is important, especially in those with pre-existing hypertension.

Effect of Ketamine on Blood Pressure

There are the following effects of ketamine on the human body and brain.
There are given as follows:

  • Ketamine is known to increase blood pressure both during administration and in the immediate aftermath. This is a direct pharmacological effect.
  • The degree of elevation depends on factors like dosage, infusion rate, and administration route. Higher IV doses cause a more significant risk of ketamine hypertension.
  • For most healthy people, ketamine-induced blood pressure spikes are temporary, lasting only minutes.
  • Factors that increase sympathetic nervous system activity can exacerbate ketamine’s pressure response, like combativeness during dissociative states.
  • Chronic recreational ketamine abuse has been associated with higher resting blood pressure over the long term due to cumulative effects.
  • People with serious cardiovascular conditions may not be given ketamine, depending on a risk/benefit analysis by their physician.

Ketamine Effects on Heart

Ketamine’s effects on the heart are given as:

  • Ketamine usually does not severely depress heart function like other anesthetics. It maintains heart rate and blood pressure better than opiates or barbiturates.
  • It can cause a small, temporary increase in heart rate and blood pressure through indirect stimulation of the sympathetic nervous system.
  • For most healthy people, ketamine increase heart rate. The effects are minor and self-limiting.
  • Chronic recreational ketamine abuse has been linked to potentially serious long-term effects like pulmonary hypertension, but data is limited.
  • Factors like dehydration, underlying illness, drug interactions, or agitation during dissociative states could potentially worsen the cardiovascular impact.

Ketamine as a Drug Abuse

Ketamine makes people isolated from the people, and the patient avoids any sort of social gathering.
Those who use ketamine recreationally report sensations such as being detached from their bodies or a pleasant sense of floating.
Some people experience almost full sensory detachment, which they liken to a near-death experience.
The substance is popular among teenagers and young adults at dance clubs.
People who use it argue that a ketamine trip is superior to a PCP or LSD trip.
This is because it generates shorter-term hallucinations that last 30 minutes to an hour rather than many hours.
That’s why it’s important to administer ketamine in a professional and controlled medical setting, where a doctor oversees everything.
Otherwise, ketamine can be misused.

Final Thoughts

Does ketamine lower blood pressure? It all depends on the dosage you are taking for treating a certain type of disorder.
When a patient intakes ketamine in high quantities, it has some side effects on mental health, including high blood pressure.
As with the low dose, taking it reduces anxiety and depression quite well.

Why ketamine is contraindicated in hypertensive patients?

Ketamine can cause a rise in blood pressure and heart rate.
This temporary effect on cardiovascular function makes it relatively contraindicated in patients with uncontrolled or severe hypertension, as the increase in blood pressure could potentially trigger dangerous complications like strokes or heart attacks.

Does ketamine lower heart rate?

While ketamine can modestly increase heart rate and blood pressure during initial administration, it does not depress heart function like some other anesthetics.
Ketamine maintains heart rate and cardiovascular stability relatively well compared to opioids or sedatives, making it safer for high-risk patients with low heart rates.

Is ketamine addictive?

Ketamine has the potential for abuse and addiction with repeated recreational use over the long term.
However, when administered by medical professionals in controlled clinical settings and dosages for therapeutic uses.

How does ketamine therapy work?

Ketamine therapy works by targeting glutamate receptors in the brain differently than other antidepressants.
It helps relieve depression symptoms rapidly by increasing connectivity between brain regions and promoting neuroplastic changes.

How many ketamine treatments for depression?

Most ketamine depression treatment plans involve six ketamine infusions administered over 2-4 weeks.
The infusions are usually done on an outpatient basis, 2-3 times per week, with the antidepressant effects often lasting between 1-2 weeks following each treatment.
