๐ฟ What is Solifenacin 5 mg (Soliact)?
Soliact contains Solifenacin Succinate, a selective M3 muscarinic receptor antagonist that relaxes bladder smooth muscle, reducing detrusor overactivity. It effectively manages OAB symptoms, improving patient quality of life by decreasing urinary urgency, frequency, and incontinence episodes.
Clinical studies show that Solifenacin 5 mg once daily significantly reduces incontinence episodes by up to 60% and decreases daytime voiding frequency. Its high selectivity for M3 receptors minimizes central and salivary gland side effects.
For comprehensive prescribing and safety information, see the FDA label for Vesicare and the Drugs.com monograph. Additional guidance is available via the NHS Medicines AโZ entry and the WHO Essential Medicines List.
