Introduction And Hypothesis:
Nationwide use and costs of anticholinergic drug for overactive bladder are unknown.
Methods:
We performed a nationwide study based on the Swedish Register on Prescribed Pharmaceuticals.
Results:
From 2000 to 2007, there was a 68.8% increase in dispensed anticholinergic drugs in a population of 9 million. More than 93 million DDDs (calculated average maintenance dose per day) of anticholinergic drugs were dispensed corresponding to an overall DDD/TID (DDD per 1,000 inhabitants per day) of 3.5 per 1,000 persons per year. Approximately two thirds of anticholinergic drugs were prescribed to women, regardless of drug type. In 2007, the cost for anticholinergic drugs was 22 million
Conclusions:
In this nationwide study, there was a 70% increased rate of expedited prescriptions of anticholinergic drugs for the treatment of overactive bladder in a relatively stable population.

Cholinergic Antagonists: Therapeutic Uses
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal secretions in common...

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
