๐ฟ What is Darifenacin 7.5 mg (Vesigard)?
Vesigard 7.5 mg offers a targeted therapy for overactive bladder (OAB) by selectively antagonizing M3 muscarinic receptors in the detrusor muscle. Unlike nonselective antimuscarinics, Darifenacinโs high M3 receptor affinity leads to potent reduction of involuntary bladder contractions, resulting in fewer urgency and incontinence episodes.
Overactive bladder significantly impacts daily lifeโpatients often experience frequent trips to the bathroom, sudden urges that disrupt activities, and social embarrassment. Early intervention with Vesigard can restore confidence, reduce nighttime awakenings, and improve overall quality of life.
Clinical studies demonstrate that a 7.5 mg daily dose of Darifenacin reduces daily incontinence episodes by up to 55% and decreases micturition frequency by an average of 2 episodes per day. Patients report improved sleep and reduced anxiety related to bladder control after four weeks of therapy.
For comprehensive prescribing and safety information, refer to the FDA label for Enablex, the Drugs.com monograph, the NHS Medicines AโZ entry, and the WHO Essential Medicines List.
