PIPELINE

Anti-depressants (VT011)

Background

Antidepressants are drugs used for the treatment of major depressive disorder and of other conditions, including some anxiety disorders, some chronic pain conditions (off-label use), and to help manage some addictions.

Typical side-effects of antidepressants include dry mouth, weight gain, lack of sex drive, and in some cases erectile dysfunction. Most types of antidepressants are typically safe to take, but may cause increased thoughts of suicide when taken by children, adolescents, and young adults. A discontinuation syndrome can occur after stopping any antidepressant. The risk is greater among those who have taken the medication for longer and when the medication in question has a short half-life. The problem usually begins within three days and may last for several months. Methods of prevention include gradually decreasing the dose among those who wish to stop, though it is possible for symptoms to occur with tapering.

Market

In the United States, antidepressants were the most commonly prescribed medication in 2013. Of the estimated 16 million "long term" (over 24 months) users, roughly 70 percent are female. As of 2017 about 16.5% of white people in the United States took antidepressants as opposed to 5.6% of black people in the United States.

In the UK, figures reported in 2010 indicated that the number of antidepressant prescribed by the National Health Service (NHS) almost doubled over a decade. Further analysis published in 2014 showed that number of antidepressants dispensed annually in the community went up by 25 million in the 14 years between 1998 and 2012, rising from 15 million to 40 million. Nearly 50% of this rise occurred in the four years after the 2008 banking crash, during which time the annual increase in prescriptions rose from 6.7% to 8.5%. These sources also suggest that aside from the recession, other factors that may influence changes in prescribing rates may include: improvements in diagnosis, a reduction of the stigma surrounding mental health, broader prescribing trends, GP characteristics, geographical location and housing status. Another factor that may contribute to increasing consumption of antidepressants is the fact that these medications now are used for other conditions including social anxiety and post traumatic stress.

R&D

Natural substances extracted from the Nelumbinis Semen (lantern seeds) relieve side effects of anti-depressants such as sexual dysfunction and weight loss.

In order to be effective, an average drug needs to take at least 14 days, but VT011 can have anti-depressant and anti-anxiety effects from one hour after taking the drug.

Natural extract Nelumbinis Semen extract is very safe.
