baclofen + oxybutynin

Baclofen + oxybutynin is a combination of two small molecule drugs used primarily in the management of overactive bladder (OAB) with abnormal voiding patterns. Baclofen is a gamma-aminobutyric acid (GABA) agonist that acts as a skeletal muscle relaxant, reducing spasticity by activating GABA-B receptors in the central nervous system[6]. Oxybutynin is an antimuscarinic agent that works by relaxing the muscles in the bladder, thereby reducing symptoms such as urgency, frequency, and urge incontinence[4][7]. The combination has been studied for its ability to reduce voiding difficulty associated with antimuscarinic therapy in women with OAB and abnormal voiding patterns; adding baclofen to oxybutynin may help mitigate these difficulties[2].
