Activase and Weed


Most people who consume marijuana do so for its mood-altering and relaxing abilities. Weed gives people a high and allows them to relax. However, heavy consumption of weed can cause unwanted results. It can increase the anxiety and depression a person experiences, and it can interact with certain other drugs including Activase. It is important to remember that interactions do occur with all types of drugs, to a great or lesser extent and this article details the interactions of mixing Activase and Weed.


Mixing Activase and Weed


Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter. It is given by injection into a vein or artery. Alteplase is the same as the normal human plasminogen activator produced in vascular endothelial cells and is synthesized via recombinant DNA technology in Chinese hamster ovary cells (CHO). Alteplase causes the breakdown of a clot by inducing fibrinolysis.

It is on the World Health Organization’s List of Essential Medicines.

Alteplase is indicated for the treatment of acute ischemic stroke, acute myocardial infarction, acute massive pulmonary embolism, and blocked catheters. Similar to other thrombolytic drugs, alteplase is used to dissolve clots to restore tissue perfusion, but this can vary depending on the pathology. Generally, alteplase is delivered intravenously into the body. To treat blocked catheters, alteplase is administered directly into the catheter.

In adults diagnosed with acute ischemic stroke, thrombolytic treatment with alteplase is the standard of care. Administration of alteplase is associated with improved functional outcomes and reduced incidence of disability. Alteplase used in conjunction with mechanical thrombectomy is associated with better outcomes.

As of 2019, alteplase is the most commonly used medication to treat pulmonary embolism (PE). Alteplase has a short infusion time of 2 hours and a half-life of 4–6 minutes. Alteplase has been approved by the FDA, and treatment can be done via systemic thrombolysis or catheter-directed thrombolysis.

Systemic thrombolysis can quickly restore right ventricular function, heart rate, and blood pressure in patients with acute PE. However, standard doses of alteplase used in systemic thrombolysis may lead to massive bleeding, such as intracranial hemorrhage, particularly in older patients. A systematic review has shown that low-dose alteplase is safer than and as effective as the standard amount.

Alteplase can be used in small doses to clear blood clots that obstruct a catheter, reopening the catheter so it can continue to be used. Catheter obstruction is commonly observed with a central venous catheter. Currently, the standard treatment for catheter obstructions in the United States is alteplase administration. Alteplase is effective and low risk for treating blocked catheters in adults and children. Overall, adverse effects of alteplase for clearing blood clots are rare. Novel alternatives to treat catheter occlusion, such as tenecteplase, reteplase, and recombinant urokinase, offer the advantage of shorter dwell times than alteplase.

A person should not receive alteplase treatment if testing shows they are not suffering from an acute ischemic stroke or if the risks of treatment outweigh the likely benefits. Alteplase is contraindicated in those with bleeding disorders that increase a person’s tendency to bleed and in those with an abnormally low platelet count. Active internal bleeding and high blood pressure are additional contraindications for alteplase. The safety of alteplase in the pediatric population has not been determined definitively. Additional contraindications for alteplase when used specifically for acute ischemic stroke include current intracranial hemorrhage and subarachnoid hemorrhage. Contraindications for use of alteplase in people with a STEMI are similar to those of acute ischemic stroke. People with an acute ischemic stroke may also receive other therapies including mechanical thrombectomy.

Given that alteplase is a thrombolytic medication, a common adverse effect is bleeding, which can be life-threatening. Adverse effects of alteplase include symptomatic intracranial hemorrhage and fatal intracranial hemorrhage.

Angioedema is another adverse effect of alteplase, which can be life-threatening if the airway becomes obstructed. Other side effects may rarely include allergic reactions.

Alteplase binds to fibrin in a blood clot and activates the clot-bound plasminogen. Alteplase cleaves plasminogen at the site of its Arg561-Val562 peptide bond to form plasmin. Plasmin is a fibrinolytic enzyme that cleaves the cross-links between polymerized fibrin molecules, causing the blood clot to break down and dissolve, a process called fibrinolysis.

Plasminogen activator inhibitor 1 stops alteplase activity by binding to it and forming an inactive complex, which is removed from the bloodstream by the liver. Fibrinolysis by plasmin is extremely short-lived due to plasmin inhibitors, which inactivate and regulate plasmin activity.

In 1995, a study by the National Institute of Neurological Disorders and Stroke showed the effectiveness of administering intravenous alteplase to treat ischemic stroke. This sparked a medical paradigm shift as it redesigned stroke treatment in the emergency department to allow for timely assessment and therapy for ischemic stroke patients.

Alteplase was added to the World Health Organization’s List of Essential Medicines in 2019, for use in ischemic stroke.

In May 1987, the United States FDA requested additional data for the drug rather than approve it outright, causing Genentech stock prices to fall by nearly one quarter. The decision was described as a surprise to the company as well as many cardiologists and regulators, and it generated significant criticism of the FDA, including from The Wall Street Journal editorial board.

After results from two additional trials were obtained, Alteplase was approved for medical use in the United States in November 1987 for the treatment of myocardial infarction. This was just seven years after the first efforts were made to produce recombinant t-PA, making it one of the fastest drug developments in history.

The cost of alteplase in the United States increased by 111% between 2005 and 2014, despite there being no proportional increase in the costs of other prescription drugs. However, alteplase continues to be cost-effective.

Alteplase is marketed as Actilyse, Activase, and Cathflo or Cathflo Activase.

Alteplase is extremely underused in low- and middle-income countries. This may be due to its high cost and the fact that it is often not covered by health insurance.

There may be citation bias in the literature on alteplase in ischemic stroke, as studies reporting positive results for tissue plasminogen activator are more likely to be cited in following studies than those reporting negative or neutral results.

There is a sex difference in the use of intravenous tissue plasminogen activator, as it is less likely to be used for women with acute ischemic stroke than men. However, this difference has been improving since 2008.


Research has found that anxiety is one of the leading symptoms created by marijuana in users, and that there is a correlation between Activase and Weed and an increase in anxiety.


Anyone mixing Activase and weed is likely to experience side effects. This happens with all medications whether weed or Activase is mixed with them. Side effects can be harmful when mixing Activase and weed. Doctors are likely to refuse a patient a Activase prescription if the individual is a weed smoker or user. Of course, this could be due to the lack of studies and research completed on the mixing of Activase and Weed.


Heavy, long-term weed use is harmful for people. It alters the brain’s functions and structure, and all pharmaceuticals and drugs including Activase are designed to have an impact on the brain. There is a misplaced belief that pharmaceuticals and medication work by treating only the parts of the body affected yet this is obviously not the case in terms of Activase. For example, simple painkiller medication does not heal the injury, it simply interrupts the brains functions to receive the pain cause by the injury. To say then that two drugs, Activase and Weed, dol not interact is wrong. There will always be an interaction between Activase and Weed in the brain11.J. D. Brown and A. G. Winterstein, Potential Adverse Drug Events and Drug–Drug Interactions with Medical and Consumer Cannabidiol (CBD) Use – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from


One of the milder side effects of mixing Activase and Weed is Scromiting. This condition, reportedly caused by mixing Activase and Weed, describes a marijuana-induced condition where the user experiences episodes of violent vomiting, which are often so severe and painful that they cause the person to scream. The medical term for Scromiting by mixing Activase and Weed is cannabinoid hyperemesis syndrome, or CHS.  For these reasons, some people choose to quit smoking weed.


It was first included in scientific reports in 2004. Since then, researchers have determined that Scromiting is the result of ongoing, long-term use of marijuana—particularly when the drug contains high levels of THC, marijuana’s main psychoactive ingredient. Some experts believe that the receptors in the gut become overstimulated by THC, thus causing the repeated cycles of vomiting.


In the long run, a person can become even more depressed. There is a belief that marijuana is all-natural and not harmful to a person’s health. This is not true and Activase and weed can cause health issues the more a person consumes it.


How does Weed effect the potency of Activase?


The way in which the body absorbs and process Activase may be affected by weed. Therefore, the potency of the Activase may be less effective. Marijuana inhibits the metabolization of Activase. Not having the right potency of Activase means a person may either have a delay in the relief of their underlying symptoms.


A person seeking Activase medication that uses weed should speak to their doctor. It is important the doctor knows about a patient’s weed use, so they can prescribe the right Activase medication and strength. Or depending on level of interactions they may opt to prescribe a totally different medication. It is important for the doctor to know about their patient’s marijuana use. Weed is being legalized around the US, so doctors should be open to speaking about a patient’s use of it.


Sideffects of Activase and Weed


Many individuals may not realize that there are side effects and consequences to mixing Activase and Weed such as:


  • Dizziness
  • Sluggishness
  • Drowsiness
  • Shortness of breath
  • Itching
  • Hives
  • Palpitations
  • Respiratory Depression
  • Cardiac Arrest
  • Coma
  • Seizures
  • Death


Interestingly, it is impossible to tell what effect mixing this substance with Weed will have on an individual due to their own unique genetic make up and tolerance. It is never advisable to mix Activase and Weed due to the chances of mild, moderate and severe side effects. If you are having an adverse reaction from mixing Activase and Weed it’s imperative that you head to your local emergency room. Even mixing a small amount of Activase and Weed is not recommended.


Taking Activase and Weed together


People who take Activase and Weed together will experience the effects of both substances. Technically, the specific effects and reactions that occur due to frequent use of Activase and weed depend on whether you consume more weed in relation to Activase or more Activase in relation to weed.


The use of significantly more weed and Activase will lead to sedation and lethargy, as well as the synergistic effects resulting from a mixture of the two medications.


People who take both weed and Activase may experience effects such as:


  • reduced motor reflexes from Activase and Weed
  • dizziness from Weed and Activase
  • nausea and vomiting due to Activase and Weed


Some people may also experience more euphoria, depression, irritability or all three. A combination of weed and Activase leads to significantly more lethargy which can easily tip over into coma, respiratory depression seizures and death.

Mixing weed and Activase


The primary effect of weed is influenced by an increase in the concentration of the inhibitory neurotransmitter GABA, which is found in the spinal cord and brain stem, and by a reduction in its effect on neuronal transmitters. When weed is combined with Activase this primary effect is exaggerated, increasing the strain on the body with unpredictable results.


Weed and Activase affects dopamine levels in the brain, causing the body both mental and physical distress. Larger amounts of Activase and weed have a greater adverse effect yet leading medical recommendation is that smaller does of Activase can be just as harmful and there is no way of knowing exactly how Activase and weed is going to affect an individual before they take it.


Taking Activase and weed together


People who take Activase and weed together will experience the effects of both substances. The use of significantly more Activase with weed will lead to sedation and lethargy, as well as the synergistic effects resulting from a mixture of the two medications.


People who take both weed and Activase may experience effects such as:


  • reduced motor reflexes from Activase and weed
  • dizziness from weed and Activase
  • nausea and vomiting of the Activase


Some people may also experience more euphoria, depression, irritability or all three. A combination of weed and Activase leads to significantly more lethargy which can easily tip over into coma, respiratory depression seizures and death.

Weed Vs Activase


Taking Activase in sufficient quantities increases the risk of a heart failure. Additionally, people under the influence of Activase and weed may have difficulty forming new memories. With weed vs Activase in an individual’s system they become confused and do not understand their environment. Due to the synergistic properties of Activase when mixed with weed it can lead to confusion, anxiety, depression and other mental disorders. Chronic use of Activase and weed can lead to permanent changes in the brain22.G. Lafaye, L. Karila, L. Blecha and A. Benyamina, Cannabis, cannabinoids, and health – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from


Activase Vs Weed


Studies investigating the effects of drugs such as Activase and weed have shown that the potential for parasomnia (performing tasks in sleep) is dramatically increased when Activase and weed are combined. Severe and dangerous side effects can occur when medications are mixed in the system, and sleep disorders are a common side effect of taking weed and Activase together.


When a small to medium amount of weed is combined with Activase, sleep disorders such as sleep apnea can occur. According to the latest data from the US Centers for Disease Control and Prevention (CDC) most ER visits and hospitalizations caused by too much weed were associated with other substances such as Activase.


How long after taking Activase can I smoke weed or take edibles?


To avoid any residual toxicity it is advisable to wait until the Activase has totally cleared your system before taking weed, even in small quantities.


Overdose on Activase and weed


In the case of Overdose on Activase or if you are worried after mixing Activase and weed, call a first responder or proceed to the nearest Emergency Room immediately.


If you are worried about someone who has taken too much Activase or mixed weed with Activase then call a first responder or take them to get immediate medical help. The best place for you or someone you care about in the case of a medical emergency is under medical supervision. Be sure to tell the medical team that there is a mix of Activase and weed in their system.


Excessive Weed intake and result in scromiting, chs, and anxiety disorder.  It is advisable to quit vaping weed if you are feeling these symptoms.

Mixing Activase and weed and antidepressants


Weed users feeling depressed and anxious may be prescribed antidepressant medication. There are some antidepressant users who also use Activase and weed. These individuals may not realize that there are side effects and consequences to consuming both Activase, marijuana and a range of antidepressants.


Studies on weed, Activase and antidepressants is almost nil. The reason for so little information on the side effects of the two is mostly down to marijuana being illegal in most places – although a number of states in the United States have legalized the drug.


Self-medicating with Weed and Activase


A lot of people suffer from depression caused by weed and Activase. How many? According to Anxiety and Depression Association of America (ADAA), in any given year, it is estimated that nearly 16 million adults experience depression. Unfortunately, that number is likely to be wrong due to under reporting. Many people do not report suffering from depression because they do not want to be looked at as suffering from a mental illness. The stigmas around mental health continue and people do not want to be labeled as depressed.


Potential side effects from mixing Activase and weed


Quitting weed to take Activase


Medical professionals say an individual prescribed or taking Activase should not stop using weed cold turkey.  Withdrawal symptoms can be significant. Heavy pot users should especially avoid going cold turkey. The side effects of withdrawal from weed include anxiety, irritability, loss of sleep, change of appetite, and depression by quitting weed cold turkey and starting to take Activase.


A person beginning to use Activase should cut back on weed slowly. While reducing the amount of weed use, combine it with mindfulness techniques and/or yoga. Experts stress that non-medication can greatly improve a person’s mood.


Weed and Activase can affect a person in various ways. Different types of marijuana produce different side effects. Side effects of weed and Activase may include:


  • loss of motor skills
  • poor or lack of coordination
  • lowered blood pressure
  • short-term memory loss
  • increased heart rate
  • increased blood pressure
  • anxiety
  • paranoia
  • increased energy
  • increased motivation


Mixing Activase and weed can also produce hallucinations in users. This makes marijuana a hallucinogenic for some users. Weed creates different side effects in different people, making it a very potent drug. Now, mixing Activase or other mental health drugs with weed can cause even more unwanted side effects.


Mixing drugs and weed conclusion


Long-term weed use can make depression and anxiety worse. In addition, using marijuana can prevent Activase from working to their full potential33.J. D. Brown and A. G. Winterstein, Potential Adverse Drug Events and Drug–Drug Interactions with Medical and Consumer Cannabidiol (CBD) Use – PMC, PubMed Central (PMC).; Retrieved September 27, 2022, from Weed consumption should be reduced gradually to get the most out of prescription medication. Marijuana is a drug and it is harmful to individual’s long-term health. Weed has many side effects and the consequences are different to each person who uses it, especially when mixed with Activase.
