Detrol is the brand name for the medication tolterodine, which belongs to the class of antimuscarinic agents. It is prescribed primarily to treat symptoms of an overactive bladder such as urgency, frequency, and urge incontinence. The drug works by selectively blocking muscarinic receptors in the bladder detrusor muscle, reducing involuntary muscle contractions. By decreasing these contractile signals, Detrol helps the bladder hold urine for a longer period between voids. This pharmacologic action alleviates the frequency and sudden need to urinate that characterize overactive bladder syndrome. Detrol is administered orally in tablet form, and its effect is dose-dependent, allowing clinicians to adjust therapy based on patient response. The medication does not cure the underlying condition but provides symptomatic relief, improving quality of life for patients experiencing bladder urgency.

Detrol is a medication used to treat overactive bladder by reducing involuntary muscle contractions. Its active component is tolterodine, a synthetic drug that acts as an antimuscarinic agent. Tolterodine blocks cholinergic receptors in the bladder wall, decreasing the signals that trigger sudden urges to urinate. By dampening these signals, the drug helps the bladder hold urine for longer periods. The medication is absorbed into the bloodstream after oral administration and reaches target tissues selectively. Once inside cells, tolterodine undergoes metabolic conversion that enhances its binding affinity to the receptors. This selective binding limits activity in non-bladder tissues, contributing to a favorable therapeutic profile. The overall effect is improved bladder control without directly influencing kidney function.

Dry mouth is a common side effect of Detrol. Constipation frequently occurs with its use. Dizziness may be experienced by some patients. Blurred vision can occasionally appear. Headache and nausea are also reported. These reactions are generally mild and not serious.

Detrol may cause dry mouth as one of its most frequently reported side effects. Some users experience constipation due to reduced gastrointestinal motility. Blurred vision can occur because the medication affects eye muscles. Dizziness or lightheadedness is also observed in many patients. Headaches are reported as a common complaint alongside the therapeutic effect. Nausea sometimes accompanies treatment and may be mild or moderate. Urinary retention, or difficulty emptying the bladder, can result from its anticholinergic action. Fatigue or a general feeling of tiredness is another typical reaction noted.
