Grapefruit juice boosts drug's anti-cancer effects

Posted: Published on August 8th, 2012

Sirolimus, a drug typically used by transplant patients to prevent rejection, has been found in previous studies to have anti-cancer properties as well. While its not currently used to treat cancer, there may be a way to give those properties a boost, and make the drug a feasible option for cancer patients by adding some grapefruit juice. A new study from the University of Chicago Medicine revealed patients taking sirolimus receive more of its anti-cancer benefits if they drink a glass of grapefruit juice every day along with the drug. The drug-juice combination was so effective that patients who drank grapefruit juice obtained three times as many benefits than those who took the drug alone. This is also interesting because of grapefruits dangerous interaction with some prescription medications, namely ones that treat high blood pressure and heart conditions. Researchers had discovered sirolimus potential anti-cancer properties from previous research. Its a drug that was discovered in the 70s, Dr. Ezra Cohen, a cancer specialist at the University of Chicago Medicine and the studys lead author, told FoxNews.com. It was clearly shown to have anti-cancer effects and anti-neoplastic effects, but it hadnt been developed for cancer extensively because the patent ran out. … Continue reading

Lower risk of serious side-effects in trials of new targeted drugs, study suggests

Posted: Published on August 8th, 2012

ScienceDaily (Aug. 7, 2012) Patients in early clinical trials of new-style targeted cancer therapies appear to have a much lower risk of the most serious side-effects than with traditional chemotherapy, according to a new analysis. Researchers at The Institute of Cancer Research, London, and The Royal Marsden NHS Foundation Trust analysed data from 36 Phase I trials run by the organisations' joint Drug Development Unit. The study, published August 7 in August's Annals of Oncology, found the overall risk to patients of suffering a life-threatening side-effect was around seven times less than for traditional cytotoxic agents*. Most new cancer drugs developed over recent years are targeted agents, which attack the specific genetic or molecular faults driving cancer growth, rather than one-size-fits-all chemotherapeutics, which kill all rapidly dividing cells. Recent studies have shown that patient response rates in Phase I trials of new-generation targeted drugs are approximately two-fold higher than for old-style drugs. But until now, the risk of side-effects to patients taking part in early stage trials of new-style drugs has been unclear. Senior author Dr Rhoda Molife, a medical oncologist and senior investigator in Phase I clinical trials in the Drug Development Unit of The Institute of Cancer Research … Continue reading

Hair-Loss Drug Tied to Depression

Posted: Published on August 8th, 2012

Young men who took Propecia for hair loss and experienced its sexual side effects also had high rates of depressive symptoms, even after stopping the drug, a retrospective study found. Among a group of men who developed persistent sexual dysfunction that continued for at least three months after they stopped taking Propecia, 75 percent reported symptoms of depression compared with 10 percent of controls who never took the drug, according to Dr. Michael Irwig of George Washington University in Washington, D.C. The symptoms were moderate-to-severe in 64 percent of the former Propecia users and in none of the controls, Irwig reported online in the Journal of Clinical Psychiatry. Read this story on http://www.medpagetoday.com. Propecia has been a popular treatment for male-pattern baldness, and sexual side effects identified during clinical trials appeared to resolve on withdrawal of the treatment. However, emerging evidence has shown that in some men the adverse effects persist, and the FDA recently amended the drug's labeling to reflect greater concern about these problems. Recent uncontrolled studies also have suggested a possible link between the drug, a 5-alpha-reductase inhibitor, and depression. To clarify this possibility, Irwig recruited a cohort of 61 men in whom sexual adverse effects persisted … Continue reading

___ Bank scandals tarnish London's reputation LONDON (AP) -- It's been a tense summer in the City of London as one bank after another has faced allegations of massive misbehavior. Bankers in the British capital, which has for centuries been a center for global business, fear its reputation has been tarnished indelibly and that a heavy-handed regulatory crackdown is looming. First came U.K. bank Barclays. Its chief executive, Bob Diamond, was forced to step down last month after U.S. and British authorities fined the bank $453 million for manipulating a key market interest rate. Other banks are being investigated for their part in the scandal. Then there was HSBC, another big London-based bank. It faces fines of up to $1 billion after the U.S. Senate issued a damming report last month alleging it had failed to stop the laundering of Mexican drug money. Back in May, JPMorgan Chase & Co. disclosed a surprise $2 billion trading loss later upgraded to $5.8 billion racked up by its London office in a portfolio designed to hedge against risks the company takes with its own money. ___ S&P closes over 1,400 for first time in 3 months NEW YORK (AP) -- It was … Continue reading

Health ministry seeks public feedback on amendments to drug trial rules

Posted: Published on August 8th, 2012

The Hindu A protest against unethical clinical trial in Bhopal. A file photo: A. M. Faruqui. The ministry of health and family welfare has published draft rules for the amendment to the Dugs and Cosmetic Rules, 1945 along with the draft guidelines for deciding financial compensation in cases of drug trial-related deaths. The Drugs and Cosmetic Rules (4th amendment) mainly aim at regulating the Ethics Committees (ECs) by adding section 122-DD and Schedule Y-1 to the original rules. On the other hand, the draft guidelines published by the Central Drugs Standard Control Organization (CDSCO) seek to determine the quantum of financial compensation to be paid in case of clinical trial related injury or death. The ministry has sought public feedback on both the draft rules (notified on July 17, 2010) and the draft guidelines (published on August 03, 2012) within 45 and 30 days respectively from the dates of publication. The draft Drugs and Cosmetic Rules (4th amendment) propose to make the registration of Ethics Committees mandatory and lay down detailed guidelines and requirements for the registration process. An EC is an important, though much abused, institution in the drug-trial process. It is responsible for reviewing the drug trial protocol, … Continue reading

BANGLADESH: Hoping to expand methadone treatment

Posted: Published on August 8th, 2012

Drug users in Dhaka are opting for injectable pharmaceuticals I think [methadone treatment] is very important for Bangladesh. It has been very well received by the beneficiaries and the success rate is good, said Tasnim Azim, director of the HIV/AIDS Programme at the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr, b) in the capital, Dhaka. Buprenorphine was intended to be used to wean injecting drug users, also known as people who inject drugs (PWID), from narcotics like heroin, but has itself become a substance of addiction, with users injecting a liquid form of it. In Bangladesh, the buprenorphine available in the [illegal] drug market is only in the injectable form, said Kunal Kishore, project coordinator of the drug and HIV prevention programme at the South Asian office of UN Office on Drugs and Crime (UNODC) in New Delhi, India. In countries where buprenorphine is used as medication in Opioid Substitution Therapy (OST), it is available only at approved treatment centres, and only in tablet form. Substitution therapy is used to wean users from the substance to which they are addicted by replacing it with a substance that has similar effects, under medical supervision. The illegal use of pharmaceutical substances, … Continue reading

Drugs companies putting profit ahead of medical discoveries, warn scientists

The multi-billion pound pharmaceutical industry has spent the last decade developing new drugs which have produced little benefit and caused considerable harm, experts say today. Click HERE to view graphic The claim that there is an "innovation crisis" in pharmaceuticals because of the difficulty and expense of discovering new drugs is a myth fostered by an industry whose chief focus is on marketing, they add. Counter to drug industry claims that the pipeline of new drugs is running dry, the number of new drugs being licensed each year has remained at between 15 and 25. But most involve minor tweaks to existing drugs, designed to grab a slice of an existing market rather than offering genuine therapeutic innovation. Independent reviews suggest that 85 to 90 per cent provide little benefit over existing treatments with some, such as Vioxx the painkiller and Avandia, the diabetes drug, causing serious side effects which led to their withdrawal, the latter's in Europe. Writing in the British Medical Journal, Professor Donald Light from the University of Medicine of New Jersey and Joel Lexchin from York University in Toronto say the situation has remained the same for 50 years.

Lost-luggage handler allegedly smuggled drugs in candy, empanadas

Posted: Published on August 8th, 2012

NEW YORK A lost-luggage handler ran an Ecuador-to-New York smuggling ring that disguised drugs in chocolates and cocaine-soaked scuba diving certificates, and he stole valuables out of flyers' misplaced bags that he was hired to deliver, authorities said Tuesday. Jorge Guerrero arranged to ship innocent-looking but drug-laden packages on cargo planes from Guayaquil, Ecuador, to New York's Kennedy Airport, authorities said as Guerrero, his wife and four others pleaded not guilty to conspiracy and other charges. The packages went to parcel-delivery companies, where the conspirators picked them up, authorities said. Seized shipments read like a bizarre shopping list: sugar and oatmeal cookies packed atop a pound of cocaine, chocolate candies laced with half a pound of heroin, and empanadas -- a Latin American savory pastry -- stuffed with over three pounds of cocaine, all in professional-looking packages as if bound for store shelves, according to authorities. Also listed was a stack of diving course diplomas that had been drenched in more than three pounds of cocaine, which was apparently to be extracted later. Guerrero sometimes picked up the packages while on his trips for a baggage-delivery company, and he also exploited his job to mine jewelry, electronics and other items … Continue reading

For every 1 spent on basic research a whopping 19 is spent on marketing, claim experts Current reward system discourages innovation, they add By Claire Bates PUBLISHED: 10:13 EST, 8 August 2012 | UPDATED: 11:08 EST, 8 August 2012 The pharmaceutical industry is in crisis because companies are rewarded for developing new drugs that have few clinical advantages over existing ones, experts say. Writing in the British Medical Journal, Professor Donald Light from the University of Medicine and Dentistry of New Jersey and Joel Lexchin from York University in Toronto, say this has discouraged innovation for the past five decades. They pointed to independent reviews that found between 85 and 90 per cent of all new drugs developed over the past 50 years have provided few benefits and considerable harms. Has the pharmaceutical industry lost its way? Professor Light and Mr Lexchin say profits have been given priority over innovation They said most research funds don't go towards finding breakthrough drugs but towards developing scores of minor variations that produce a steady stream of profits. Heavy promotion of these drugs can account for up to 80% of a nations drug spending, they add. The duo warn that companies exaggerate research … Continue reading
