“I'm not great at the advice. Can I interest you in a sarcastic comment?”

This is what ‘Friends’ actor Matthew Perry’s character Chandler Bing was known for. He was known for being funny. However, he had his own struggles in his personal life and those struggles were acute depression. He was treating it with ketamine infusion therapy which is legal in the US and the UK.

What is Ketamine infusion therapy?

Ketamine is an anaesthetic used to treat depression, anxiety and pain under supervised and controlled medical settings. However, it does have its side effects, which can lead to distortion of sight, sound and time. It can also produce calming and relaxing effects.

Ketamine increases a person’s heart rate and blood pressure. If overdosed, it can leave users confused and agitated and can cause them to hurt themselves without even realising it. It can also lead to liver damage and bladder problems.

However, when used in moderation and under the supervision of medical doctors, it can treat depression where traditional antidepressants have failed.

Prof Rupert McShane, a University of Oxford psychiatrist who runs an NHS ketamine treatment clinic told BBC that ketamine “probably turns off the area of the brain that is involved in disappointment.”

Can Ketamine Infusion Therapy Kill Someone?

In simple terms, it cannot, be if the dosage is given in a controlled setting and as prescribed. Ketamine infusion therapy uses drugs in small doses than those used for anaesthesia. It acts faster than traditional anti-depressants, but the effects also wear off way quickly. Which is why it is important to monitor patients’ mental state for relapsing back into depression and discouraging them from overdosing on it.

There are ways of giving people ketamine. One of the ways is through “infusing”, which means to use an IV drip. However, injections, nasal sprays and capsules are also methods used to give people ketamine.

Since the dosage of ketamine used in the infusion treatment is small, it being the reason of actor Perry’s death was ruled out. The medical examiner also noted that Perry’s last ketamine infusion therapy session happened more than a week before his death, which means by the time he had died, it must have worn off.

So, What Happened To Perry?

Though Perry’s last session was more than a week before, his post-mortem showed that his blood contained a high concentration of ketamine. He had died of the “acute effects” of ketamine.

If it was not his session, then how did he get ketamine?

Prosecutors alleged that his assistant gave him at least 27 shots of ketamine in four days before his death, reported BBC.

Perry has been open about his personal struggles and this is what the doctors and dealers used against him. Martin Estrada, the US attorney for California’s Central District told the BBC that people took advantage of his condition. They charged him 165 times more than what vials of ketamine cost.

Names that have come up include Dr Salvador Plasencia, drug dealers “Ketamine Queen” aka Jasveen Sangha and Eric Fleming, and Perry’s live-in assistant Kenneth Iwamasa.

Who Are These Names And What Did They Do?

Ketamine Queen or Sangha supplied drugs that led to Perry’s death. Her home was a “drug-selling emporium,” said Estrada. More than 80 vials of ketamine, and thousands of pills including methamphetamine, cocaine and Xanax were allegedly found in her house known as the “Sangha Stash House.”

Sangha is known to deal with high-end celebs and was a “major source of supply for ketamine to others as well as Perry,” said Estrada.

Dr Plasencia called Perry a “moron” while charging him $2,000 for vials that cost only $12. He sold Perry 20 vials of ketamine between September and October 2023, costing $55,000.

He was the one who taught Iwamasa, who had no medical knowledge to inject the drug. This is after he knew that “Perry’s ketamine addiction was spiralling out of control,” as per what the investigators told the BBC.

Another dealer Fleming was told by Sangha to “delete all our messages.” While Fleming pleaded guilty to conspiring to distribute drugs unlawfully, he also allegedly messaged Sangha: “Please call...Got more info and want to bounce ideas off you. I’m 90% sure everyone is protected. I never dealt with [Perry] only his assistant. So the assistant was the enabler.”

The court documents also revealed that he asked Sangha on whether the ketamine stays in your system or “is it immediately flushed out.”

Dr Pepper, Bots, Cans

The people who allegedly exploited Perry used coded language for ketamine and called it “Dr Pepper”, “bots”, or “cans.”

Selling overpriced drugs, taking advantage of Perry’s mental condition and falsifying medical records to make the drugs given to him look legitimate by Dr Plasencia is what took Perry’s life.

Iwamasa is said to have administered more than 20 shots of ketamine and three on the day Perry died. Whereas ketamine is only administered by a physician. Authorities also found that weeks before Perry’s death, Dr Plasencia allegedly bought 10 vials of ketamine and intended to sell to Perry.

He also injected Perry with a large dose, two days later. This caused him to “freeze up” and spiked his blood pressure.

When I Die, I Want Helping Others To Be The First Thing That’s Mentioned

Perry had always been open about his drug addictions, struggles with alcohol and his depression. He said that his openness would help others who are also struggling and wanted to be remembered by his quote which also is on the homepage of the Mattew Perry Foundation that helps others struggling with the disease of addiction: “When I die, I want helping others to be the first thing that’s mentioned.”

Five arrests have been made in the case so far.

reaImagine developing a strange medical condition in which an injury or even a minor fall may trigger a process that may gradually turn muscles, tendons and ligaments into bone.

This is what fibrodysplasia ossificans progressiva (FOP), one of the world’s rarest genetic disorders, looks like.

The US Food and Drug Administration recently approved a new treatment option for FOP called Atebrioz (zilurgisertib), a once-daily pill developed by Mirum Pharmaceuticals.

Adults and children aged 12 years and above with FOP are eligible for this treatment. It is designed to reduce the formation of new bone outside the skeleton.

What Is Fibrodysplasia Ossificans Progressiva?

FOP is a rare genetic disease in which connective tissues like muscles, tendons and ligaments gradually turn into bone. The abnormal bone formation is known as heterotopic ossification, meaning bone starts to develop in places where it should not.

Over time, this can pose restriction in movement, cause deformities and lead to severe disability. The condition could affect quality of life significantly as well as shorten life expectancy.

FOP is usually diagnosed in childhood. According to Mirum, around 300 people in the US and about 900 worldwide are known to have the condition.

Why Does The Body Starts Making Bone In The Wrong Places?

FOP is caused by mutations in a gene involved in bone growth, especially the ACVR1 gene, which produces a protein called activin A receptor type-1, or ALK2. In people with FOP, this pathway becomes abnormally active. As a result, the body can start producing bone within soft tissues.

This process can occur in episodes called flare-ups. Trauma, surgery or other triggers can sometimes provoke inflammation and subsequent abnormal bone formation. The problem is that once mature bone has formed in these tissues, it can permanently restrict movement.

More About The New Drug

Atebrioz contains zilurgisertib, an oral drug that blocks ALK2, the protein that is abnormally active in most people with FOP and triggers bone formation outside the skeleton.

The aim is not to remove bone that has already formed. Instead, the treatment is designed to reduce the formation of new abnormal bone.

FDA’s approval was based on a randomised, placebo-controlled trial involving 63 people with FOP. Participants received either zilurgisertib or placebo for 24 weeks, followed by an extension period.

At week 24, patients receiving Atebrioz had an average 3.2 cm³ decrease in the volume of newly formed abnormal bone, compared to a 24.6 cm³ increase in the placebo group. The FDA said the difference supported the drug’s effectiveness in reducing new heterotopic ossification.

Symptoms & Treatment Of FOP

The disease can vary between individuals, but abnormal bone formation can progressively restrict movement. People with FOP may develop difficulty moving their neck, shoulders, spine, hips and other joints as new bone forms around them.

The condition can eventually affect mobility substantially. Extra bone formation can also interfere with everyday activities and contribute to severe disability.

Another characteristic feature is that people with FOP are often born with abnormalities of the big toes, which can help doctors recognise the rare condition early.

Atebrioz is not the first FDA-approved treatment for FOP. The FDA approved Sohonos (palovarotene) in 2023 as the first treatment for the disease.

More recently, the FDA approved Pasatru (garetosmab-grts) in August 2026, making Atebrioz the third FDA-approved treatment for FOP. The newer options differ in how they target the abnormal bone formation.

A confirmed case of mpox has been detected in Bunia, the capital of Ituri province in the Democratic Republic of Congo (DRC), where health authorities are already battling the country's largest-ever Ebola outbreak.

The development has raised concerns about the additional pressure on an already stretched outbreak response and the overall healthcare system.

The mpox case was confirmed after a 21-year-old woman was hospitalised with skin lesions that ae commonly seen in mpox.

The two viruses are not associated with each other, but the threat of two highly infectious diseases is now being navigated in the same area at the same time.

Mpox Case In Congo Amid Ebola Outbreak

Ituri is at the centre of one of the worst Ebola outbreaks the country has ever seen. As of September 23, the DRC reported 7,890 confirmed Ebola cases and around 3,799 deaths. The a case-fatality ratio, according to WHO, stayed put at 48.1%. Ituri, the epicenter of the outbreak, solely accounted for 6,032 confirmed cases.

The Ebola outbreak has also expanded geographically, with new cases reported across 63 health zones in seven provinces. The WHO says the continued spread is increasing the risk of cross-border transmission.

The appearance of mpox in Bunia, against the backdrop of Ebola, creates another challenge for surveillance, testing, infection prevention and safety of healthcare workers.

What Is Mpox?

Mpox is a viral disease that can cause fever, swollen lymph nodes, muscle aches, and peculiar rash or skin lesions. It spreads mainly through close physical contact with an infected person.

Some people recover without complications, while others can develop serious symptoms, particularly those with weak immune systems.

The newly case is especially alarming as the DRC had declared an end to mpox as a national public health emergency in April, following a three-year outbreak that resulted in more than 34,000 confirmed cases nationwide.

Burden On An Already Overwhelmed Healthcare System

The two diseases are caused by different viruses and spread differently. A confirmed mpox case does not indicate that Ebola has mutated or that the two outbreaks are connected.

The WHO says the Ebola response is already operating under difficult conditions, with conflict, insecurity, population displacement and limited access to basic services hampering surveillance, contact tracing, infection prevention and timely care.

The concern is that health systems, that were already dealing with a major outbreak, now have another infection to detect, investigate and contain.

Bunia is not just another location where a case has been detected. It is the capital of Ituri, where the Ebola outbreak is the most concentrated.

WHO teams have described Bunia as a key operational hub for the response, with flights transporting healthcare workers, medicines and other supplies to affected regions.

The immediate priority will be investigation, contact tracing, and surveillance to determine whether the case is linked to a wider cluster.

DRC is already conducting extensive contact monitoring for Ebola. As of September 23, more than 32,000 people were listed for follow-up, depicting the scale of the response.

The US Food and Drug Administration has approved tavapadon, a once-daily oral medicine for adults with Parkinson’s disease. This has added a new option to Parkinson's treatment strategy that has long relied on drugs that mimic the brain’s dopamine supply. The drug will be sold in the US under the brand name Juvmo.

Tavapadon is different from traditional dopamine agonists because it selectively targets D1 and D5 dopamine receptors. It has been studied both as an early treatment and alongside levodopa in people with more advanced Parkinson’s disease and motor fluctuations.

Parkinson’s Disease & Dopamine

Parkinson’s disease is a progressive neurological disorder in which dopamine-producing nerve cells in a region of the brain called the substantia nigra disappear gradually.

Dopamine is essential for controlling movement. As its levels fall, people can develop symptoms like tremor, stiffness, slowness of movement and problems with balance.

This is why many Parkinson’s treatments entail increasing dopamine levels or mimicking its effects in the brain.

How Does Tavapadon Work?

Tavapadon is a selective D1/D5 partial dopamine agonist. It means that it does not simply increase the amount of dopamine in the brain. Instead, it binds to particular dopamine receptors and partially activates them, essentially helping reproduce some of dopamine’s signalling effects.

Most currently available dopamine agonists target D2/D3 receptors. Tavapadon’s D1/D5 is therefore one of its distinguishing characteristics. Researchers have been investigating whether this drug can can help provide motor symptom relief while avoiding some adverse effects linked with dopamine receptor activation.

The FDA’s approval was supported by the phase 3 TEMPO clinical programme. In TEMPO-1, which involved 529 people with early Parkinson’s disease, both 5 mg and 15 mg daily doses of tavapadon significantly improved motor function compared to placebo after 26 weeks.

The drug has also been studied in people already taking levodopa who experience motor fluctuations, a common problem with progressive Parkinson’s. In the TEMPO-3 trial involving 507 participants, adding tavapadon to levodopa increased daily 'on' time without troublesome dyskinesia compared to placebo.

As Parkinson’s disease progresses, some people taking levodopa experience periods when the medicine is working well and movement improves. This is called 'on' time. When the medication’s effect wears off and Parkinson’s symptoms return, it is called 'off' time.

Treatment aims to increase 'on' time while limiting troublesome involuntary movements, known as dyskinesia.

Side Effects Of Tavapadon?

Tavapadon was generally tolerated in the clinical trials, but it is not free of side effects. In the TEMPO-1 trial, the most commonly reported adverse events were:

• Nausea
• Headache
• Dizziness

The FDA’s approval follows data showing improvement in Parkinson’s symptoms, but longer-term safety remains an important factor that needs more investigation.

Dopamine agonists can also be associated with sleepiness, low blood pressure on standing, hallucinations and impulse-control disorders. These issues remain relevant when doctors consider where tavapadon fits into an individual’s treatment plan.

Tavapadon treats the symptoms of Parkinson’s disease. It does not restore the dopamine-producing nerve cells that have been lost or stop the neurodegenerative process.
