Drug dissolution testing and establishing plasma drug levels in humans

Drug dissolution testing and establishing plasma drug levels in humans5

Dissolution testing is a very important tool that determines and help understand the performance and effectiveness of oral solid dosage forms. It is significant for the field of medicine because if a drug has to be effective, it must be released first from the product form, and it should then be allowed to get dissolved in the gastrointestinal fluids. This is the first step that leads to the next important phase, that of the dosage’s absorption into the bloodstream. This points to the fact that dissolution from the dosage form is a major determinant of the rate and extent to which the drug gets absorbed by the body.

Drug dissolution testing is very important during the development of drugs and drug formulations. It helps to determine if the right concentration of the drug reaches the desired or expected locus of action. This makes the investigation of the factors which affect drug absorption into the human blood flow when a drug product is taken orally important.

The usual method of measurement of drug absorption is in vivo, or, the body of a living being such as a human or animal. Time blood plasma concentration profiles of drugs after oral administration constitute an important in vivo parameter. In-vitro investigations are carried out for identifying the parameters involved in drug absorption. These are investigations that are conducted in a controlled and simulated environment that resembles biological conditions closely.

Thorough learning of drug dissolution

Drug dissolution testing and establishing plasma drug levels in humans

An important seminar from GlobalCompliancePanel, a leading provider of professional trainings for all the areas of regulatory compliance, will offer valuable learning on all the aspects of drug dissolution testing and explain the ways of establishing plasma drug levels in humans.

At this two-day seminar, Dr. Saeed Qureshi, who has worked as a research scientist with Health Canada and is an internationally known expert on the subject whose expertise spans the areas of drug dissolution testing, pharmacokinetics, biopharmaceutics and analytical chemistry as related to animal and human studies for developing and evaluating pharmaceutical products; will be the Director.

In order to gain the benefit of learning from this world-renowned expert, please enroll for this seminar by visiting Drug dissolution testing and establishing plasma drug levels in humans. This course has been pre-approved by RAPS as eligible for up to 12 credits towards a participant’s RAC recertification upon full completion.

All aspects of drug dissolution and establishing plasma drug levels

Drug dissolution testing and establishing plasma drug levels in humans1

This seminar will provide its participants a unique opportunity to learn scientifically valid drug dissolution testing and establishing plasma drug levels. Lab personnel take several approaches to conduct dissolution testing using different apparatuses and methods. This makes section of an appropriate apparatus and method confusing and challenging. Dr. Qureshi will offer relevant pharmacokinetics and physiological background that is aimed at making this choice easier and intuitive. He will use simple and clear language in helping participants understand how to select or develop a dissolution method. He will describe the theoretical aspect of the drug dissolution testing, including method development, in detail. He will explain the pros and cons of different approaches.

Another important area that Dr. Qureshi will address is in vitro-in vivo correlation (IVIVC). He will address the particular issue of the use of the concepts of convolution/deconvolution and IVIVC in providing an estimate/prediction of expected drug levels in humans through drug dissolution testing. This approach has met with limited success. Dr. Qureshi will explain the reasons for this and suggest alternative approaches and will offer an explanation of the underlying scientific principles involved in convolution, deconvolution and IVIVC techniques with simple practical examples. He will describe a unique and simple approach based on convolution technique using spreadsheet software.

He will show in vitro drug dissolution testing and convolution/deconvolution techniques for predicting plasma drug levels using the principles of pharmacokinetics and physiology. Dr. Qureshi will cover the following main areas at this seminar, with its relevant subtopics:

Personnel who work in various levels of the areas of Pharmaceutical Development, setting up analytical methods (pharmacopeial, regulatory or in-house developed), R & D (both analytical and formulation), Project Management, Quality Control, Quality Assurance, and Regulatory Affairs will benefit enormously from this learning.

Breast cancer warning from man stunned by ‘impossible’ diagnosis

Breast cancer warning from man stunned by 'impossible' diagnosis.jpg

When you think of breast cancer, you think of a form of cancer that affects only women. It doesn’t.

While breast cancer in men is rare it’s still an issue for the 10 men on average who are diagnosed with it every year in Northern Ireland.

Ian Cranston, 70, was diagnosed with breast cancer in May. Two weeks later he had a mastectomy.

The Portadown father-of-two was given the all-clear in June and has decided to speak publicly to make men aware that it’s a cancer that doesn’t just affect women.

He said “men also need to check their breasts for changes”.

Inverted nipple

In May, Ian’s wife Elizabeth noticed something wrong when he got out of the shower.

She told him he had an inverted nipple and needed to see his GP.

“I didn’t know what that meant,” said Ian.

“Men can’t get breast cancer, I don’t have to go to the doctor.

“I wasn’t aware I had breasts. This is my chest, men don’t have breasts, it’s impossible,” he added.

Eventually his wife persuaded him to go to his GP, who referred him to Craigavon Area Hospital.

The diagnosis stunned him.

“Men having breast cancer, I couldn’t believe it,” he said.

“I couldn’t do or say anything. My wife Elizabeth cried.”

Four days later Ian said he “just broke”.

He has decided to help try and raise awareness of the disease, saying that if his speaking out helped one man, it would be worth it.

“I can understand where women are coming from because I’ve had breast cancer myself,” he said.

MS could be reversed with existing allergy drug

MS could be reversed.jpg
In a recent phase II clinical trial, an over-the-counter allergy drug was shown to improve nervous system function in patients with multiple sclerosis.

Multiple sclerosis (MS) is an autoimmune disease affecting more than 2.3 million people around the world. The condition attacks myelin, or the waxy coat around nerves, and compromises the nerves’ ability to transmit messages.

Over time, as the nerves’ function is steadily reduced, a range of symptoms — including problems with vision, muscle weakness, difficulty walking, and issues with balance and coordination — develop.

Current treatment focuses on preventing the immune system from causing further damage, and as it stands, no drugs can repair the damaged myelin.

Discovering a medication capable of rebuilding the damaged myelin would be a huge step forward. And according to the latest study, this may be just around the corner.

New MS drug on the horizon?

In 2014, studies carried out by Prof. Jonah R. Chan at the University of California, San Francisco showed that clemastine fumarate may be a candidate for the treatment of MS.

Because of the potential importance of the findings, the drug quickly progressed to clinical trials. This week, the results from a phase II clinical trial on clemastine fumarate are published in The Lancet.

Clemastine fumarate was first approved by the Food and Drug Administration (FDA) in 1977. It is an antihistamine medication for allergies and has been available over the counter since 1993. Its potential to treat MS is therefore as surprising as it is welcome.

According to principal investigator Dr. Ari Green, “To the best of our knowledge, this is the first time a therapy has been able to reverse deficits caused by MS. It’s not a cure, but it’s a first step toward restoring brain function to the millions who are affected by this chronic, debilitating disease.”

Drugstore stocks tumble as Amazon considers selling prescription drugs online

Drugstore stocks tumble as Amazon considers selling prescription drugs online

Shares of drugmakers dropped in midday trading Friday after CNBC reported Amazon is in the final stages of considering an entrance into selling drug prescriptions.

Walgreens, Rite Aid and CVS Health stocks each slipped 4 percent or more as investors worried Amazon may disrupt the traditional distributors’ hold on the drug prescription market.

Amazon will decide before Thanksgiving whether to move into selling prescription drugs online, according to a source and an email from Amazon viewed by CNBC.

Amazon typically spends years researching opportunities before it telegraphs its intentions. The opportunity to sell drugs online is alluring given its market size – analysts have estimated the U.S. prescription

Are any weight loss supplements considered safe?

Are any weight loss supplements considered safe.jpg

Every year, millions of Americans go after this same goal, some successful and others not so much. To attain their goals, they may choose from the over-abundance of diets and exercise programs available, and some turn to weight loss supplements as well.

While you shouldn’t rely on supplements to do all the work for you, there are a few that can be used safely to boost your weight loss efforts.

Before you decide on weight loss supplements, though, you should consider the health effects carefully. Always check with your doctor first to be sure about safety, and remember that these pills are supplements. They’re meant to be used alongside healthy eating habits and proper exercise.

DO YOU HAVE LIVER DAMAGE?

Again, never use supplements by themselves to lose weight. Some people turn to weight loss pills so that they can continue an unhealthy lifestyle while staying thin.

 This dangerous mentality could lead to frightening situations like addiction, overdose or death. Also, brands that claim to shed weight without any effort may contain ingredients that will do you more harm than good. If you have any doubt about a supplement, stay away.

Weight Loss Supplements that Work

Just like any other medication, weight loss supplements have both benefits and side effects. When choosing a supplement, you should know all the possible effects and consider them in light of your own health history. Especially if you have other health issues, you should check carefully for ingredients that may trigger or worsen your symptoms.

Let’s look at 3 supplements that you could consider adding to your weight loss program:

1. Green Tea Extract

Green tea has long been known for its health benefits, mainly because the drink is high in antioxidants. In particular, green tea contains large amounts of polyphenol antioxidants called catechins, which may help reduce oxidative stress.

For weight loss, studies have shown that green tea extract can help boost the metabolism. Researchers think that the combination of antioxidants and caffeine work together to accomplish this goal.

Depression: Is brain inflammation tied to suicidal thoughts?

Depression Is brai.jpg
A new study confirms the link between inflammation of the brain and the prevalence of suicidal thoughts in people diagnosed with major depression. This is the first study of its kind to measure relevant biomarkers in living individuals.

Major depression is a very common mental condition, with 6.7 percent of all adults in the United States having had at least one severe depressive episode in 2014 or 2015.

According to the World Health Organization (WHO), depression is also currently the leading cause of years spent with disability worldwide.

Some people diagnosed with major depression experience suicidal thoughts, which may result in suicide attempts. In the U.S., “suicide is the 10th leading cause of death.” Now, researchers wonder whether or not suicidal ideation in people with major depression may be linked to abnormal inflammation of the brain.

Dr. Peter Talbot and other researchers based at the University of Manchester in the United Kingdom have conducted a study testing the levels of a biomarker associated with brain inflammation in the systems of people diagnosed with clinical depression.

The scientists’ findings were reported in the journal Biological Psychiatry.
