Duratia (which contains the active ingredient Dapoxetine) is primarily used to treat premature ejaculation rather than to increase stamina in a general sense. Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) that works by increasing serotonin levels in the brain, which can help delay ejaculation. While some individuals might perceive improved stamina due to delayed ejaculation, Duratia is not specifically intended or clinically proven to increase overall physical stamina or endurance. Stamina typically refers to physical endurance or the ability to sustain prolonged physical or mental effort, and medications like Duratia are targeted towards specific sexual health concerns. If you are looking to increase stamina in a broader sense, such as physical endurance during exercise or mental stamina during tasks, lifestyle changes, regular exercise, proper nutrition, and adequate rest are generally recommended. It's always best to consult with a healthcare provider to discuss your specific health goals and determine the most appropriate course of action.
