"It may in part be because those longer-term users are in increasingly poor health," Barnes explains.
It was Dr. Richard S. Bockman, a professor at the Joan and Sanford Weill Medical College of Cornell University, who said a proposed "drug holiday" for longer-term users of the drugs was not warranted by current scientific evidence.
A few studies have reported elevated risks in longer-term users of some agents (Cotterchio et al, 2000; Moorman et al, 2003), but the class has differed.
This observation suggests that a drop in adherence may occur with increasing duration of treatment: longer-term users may be less enthusiastic or motivated about adhering to treatment compared with those users new to treatment, who may be more diligent.
As to whether there is longer term user demand for this kind of thing?
The plans aren't too shabby — longer term users can shell out $25 for 1.5GB of access per month, while paying $35 and $50 will net them 3.5GB and 5GB of sweet sweet wireless data per month respectively.
This resulted in some attenuation of risk that was restricted to recent users, as expected, but little change in risks for longer term users of eight years or more.
There was no clear signal of dose responsiveness in one observational study that separated participants into different dose levels, 25 whereas one RCT suggested that longer term users of budesonide with greater cumulative doses had lower BMD compared to those who received lower cumulative doses.
defer.add img); For longer term users, withdrawals aren't completely the same.
Another case control study in the United Kingdom revealed a decreased risk of any fracture for longer-term current users (≥20 prescriptions) of ACE inhibitors (adjusted OR, 0.81; 95 % CI 0.73 0.89), though, subanalysis for hip fracture was not conducted.
In the same study, rates of breast cancer were lower in longer-term compared to shorter-term users of estrogen plus testosterone.
