A literature review, including 60 national and foreign publications, was carried out. The review focuses on aspects of the pathogenesis and pathophysiology of overactive bladder (OAB). The effect of OAB on a woman's sexual function is described, as well as the features of OAB treatment in comorbid patients and complications of using anticholinergics drugs.
The analysis showed that currently available drugs are highly effective, but have some adverse effects. A combination of various M-anticholinergics or M-anticholinergic drugs with α-blockers or β3-adrenoceptor agonists can be used. Trospium chloride is preferrable drug for older patients, especially with cognitive impairment and dementia, as well as for patients receiving drugs metabolized by the cytochrome P450 for concomitant diseases or those with bladder tuberculosis.
