The overactive bladder is a combination of symptoms caused by the spontaneous contraction of the bladder muscles with the accumulation of urine. These signs include frequent urination, the desire to empty the bladder at night, unrestrained urge, which can lead to urinary incontinence.
At the heart of the mechanism of hyperactivity lies the increased sensitivity of the bladder receptors to stretching and increasing the detrusor contractile activity, the overactivity of which will be the primary cause. Detrusor hyperactivity is called the urodynamic phenomenon, which includes a sequence of involuntary spontaneous or after provocations detrusor cuts, the suppression of which does not depend on the volitional effort.
Drugs action is based on suppression of muscarinic receptors, responsible for contraction of the muscle of the bladder. Blockade of receptors causes a decrease in muscle activity, symptoms of GAMP decrease or pass.
In the treatment of overactive bladder, a doctor will prescribe anticholinergic drugs, which often have the additional property of spasmolytic. They help to remove muscular spasm of internal organs, including the bladder.
