“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.
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.”
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.
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.
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.”
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.
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.

Tech giant Amazon’s cloud unit has launched a new AI-powered application, Amazon Bio Discovery, that will help scientists design and test novel drugs more quickly, bringing new medical treatments to patients faster.
Developed by Amazon Web Services, the new agentic AI application—a smart assistant that automates complex tasks—helps scientists select the right models for their research goals, optimize the inputs, and evaluate candidates for experimentation.
"AI agents make powerful scientific capabilities accessible to all drug researchers, not just those with computational expertise," said Rajiv Chopra, vice president of AWS Healthcare AI and Life Sciences.
"These AI systems can help scientists design drug molecules, coordinate testing, learn from results, and get smarter with each experiment. This combination of cutting-edge AI and the robust, secure infrastructure AWS has built for regulated industries allows scientists to accelerate antibody discovery in ways that weren't possible before," Chopra added.
With the help of Amazon Bio Discovery, scientists can run complex computational workflows without writing code.
Notably, the platform also gives scientists direct access to a broad catalog of specialized AI models called biological foundation models (bioFMs) that are trained on vast biological datasets. These models generate and evaluate potential drug molecules, known as candidates, helping scientists accelerate antibody therapies during the early stages of drug discovery.

Amazon Bio Discovery also enables scientists to securely feed prior experimental data from their organization's lab results into the application. They can use their own lab data to train custom models with just a few clicks—no need to build complex training pipelines or write custom code.
Amazon Bio Discovery also provides three key capabilities:
Amazon Bio Discovery provides complete data isolation and gives customers ownership over all their proprietary data and intellectual property.
According to AWS, Bayer, the Broad Institute, Fred Hutch Cancer Center, and Voyager Therapeutics are among early adopters, and 19 of the top 20 global pharmaceutical companies already use its cloud services.
In a collaboration with Memorial Sloan Kettering Cancer Center, AWS said the platform used multiple models to generate nearly 300,000 novel antibody molecules and narrow them to 100,000 candidates for lab testing by partner Twist Bioscience, compressing work that can take months into weeks.
Drugmakers and technology companies have stepped up efforts to use AI to accelerate drug development.
Recently, Danish pharmaceuticals group Novo Nordisk, maker of the popular Ozempic and Wegovy anti-obesity drugs, announced a "strategic partnership" with OpenAI to accelerate the development of new medications.

Diabetes patients rely upon metformin for controlling their blood sugar and insulin levels. Now, a new study claims that this common diabetes drug has many other health benefits to offer, and these can mimic the benefits of 'intense workouts.' The diabetes drug metformin is used by millions around the world who are struggling with this lifestyle disorder—it releases weight-regulating compounds in the body, the same ones that are released during workouts in inactive people. American scientists found that the drug can have a positive impact on a sedentary lifestyle—find out how.
What is metformin?
Metformin is the most common drug for the management of type 2 diabetes. It helps insulin work better, thereby regulating blood sugar spikes. This drug is usually prescribed when diet and workouts alone are not sufficient for weight management. According to a study by experts at the University of Miami Miller School of Medicine’s Sylvester Comprehensive Cancer Center, metformin may replicate the benefits of workouts in people who follow a sedentary, inactive lifestyle. In the case of prostate cancer patients, men who do not work out because of their treatment benefited from metformin use, as the drug raises levels of a molecule that supports weight loss. In the case of patients who cannot work out properly, the effect can be game-changing.
Are workouts necessary during cancer treatment?
Exercising is one of the best ways to avoid obesity and other metabolic disorders. It is also one of the best ways to stay strong during cancer treatment, as it regulates weight, heart health, and blood sugar. This helps cancer patients feel stronger even during treatment and recovery. However, many cancer patients cannot work out regularly because of hormone therapy-related fatigue. Metformin use, in this case, can prove helpful for patients.
How does metformin mimic the benefits of workouts?
Exercising benefits the body by releasing hormones such as oxytocin and dopamine. Researchers from the Sylvester Comprehensive Cancer Center explored whether these could be triggered without exercise and whether metformin could do that. They noted that while the drug cannot fully replace workouts as part of a healthy routine, there is a need to understand how a widely used drug can be beneficial for metabolic health during prostate cancer treatment.
N-lactoyl-phenylalanine, or Lac-Phe, is a molecule that spikes after an intense workout session, and it also regulates appetite and calorie burning. Scientists found that Lac-Phe levels were higher in metformin users even when they were not working out. The Sylvester team noted that prostate cancer patients often struggle with poor blood sugar control, heart disease risk, and weight gain due to hormone therapy. They then took blood samples from 29 people and found that the patients who took metformin had similar Lac-Phe levels to people who were engaged in strenuous workouts. This was noted even when the patients were not exercising. However, metformin did not have an impact on prostate tumours.
The study was published in the EMBO Molecular Medicine journal.

In an alarming incident, more than 330 children in Pakistan have contracted HIV due to reuse of syringes in a hospital in Pakistan’s Punjab, according to a report.
The report, based on an undercover investigation by BBC News, highlighted blatant infection control failures and unsafe medical practices at THQ Hospital Taunsa in Pakistan.
The failures captured on camera, filmed over 32 hours inside THQ Taunsa Hospital in late 2025, showcase persistent unsafe practices, including the reuse of syringes on multi-dose vials, that have infected more than 330 children with HIV since late 2024.
The footage captured multiple violations of basic hygiene protocols, including the staff reusing syringes on multi-dose medicine vials, which increases the risk of contaminating entire batches of medication. In several instances, the same vial was then used to treat different children, the report said.
Other scenes captured included poor sanitation conditions, such as open vials, used needles left on countertops, and improper disposal of medical waste; staff administering injections without sterile gloves, further increasing the risk of cross-contamination.
The incident in Taunsa is not the first. In 2019, media reports cited nearly 1,000 children testing positive for HIV due to the reuse of needles in southern Sindh province.
“Pakistan has experienced a series of HIV outbreaks over the past two decades, but we’ve never before seen this many young children infected or so many health facilities involved," Dr Fatima Mir from the Aga Khan University in Pakistan, told The Guardian. She was the lead author of the paper published in the Lancet Infectious Diseases, which also reported the cases.
“Use of syringes and needles is widespread, and Pakistan has one of the highest rates of unsafe injections in the world. Health practitioners need to use intravenous treatment only when necessary, use needles only once, and screen blood for infections before using it for transfusions,” she added.
In 2025, a dozen children undergoing blood transfusions for thalassemia contracted HIV in two different incidents in India's Madhya Pradesh and Jharkhand, highlighting “systemic lapses in blood bank regulations”.
At least six children were found HIV positive at Satna district hospital in Madhya Pradesh, allegedly due to contaminated blood transfusions at the district hospital during treatment for thalassemia.
The children affected include five boys aged under 11 and a nine-year-old girl who have been undergoing blood transfusions at the hospital.
Another six children with thalassemia reportedly contracted HIV from contaminated blood transfusions at a government hospital in the West Singhbhum district of Jharkhand.
The World Health Organization (WHO) mandates the use of single-use, safety-engineered syringes—specifically auto-disable (AD) or reuse-prevention (RUP) devices—to prevent disease transmission and needle-stick injuries.
These devices automatically lock or break after one use and are essential for immunization and medication administration.
The US CDC recommends using single-dose vials whenever possible, over multiple-dose vials, especially when medications will be administered to multiple patients.
Do not administer medications from a syringe to multiple patients, even if the needle or cannula on the syringe is changed.
