Kentera, known generically as oxybutynin, is a medication primarily used in the management of overactive bladder symptoms, such as urinary urgency, frequency, and incontinence. It functions as an antimuscarinic agent, working by relaxing the muscles in the bladder to help decrease the urgency and frequency of urination. Kentera is distinctively formulated as a transdermal patch, which allows for the gradual release of the medication through the skin, providing a convenient and consistent dosing alternative to oral forms. This method of delivery can also help minimize some of the common side effects associated with oral antimuscarinics, such as dry mouth and constipation. Kentera patches are typically applied to the skin once every three to four days, according to the prescribing information.
