The primary difference between capsules and tablets for enzalutamide lies in their formulation and delivery method. Enzalutamide capsules contain the active ingredient enzalutamide in a gelatin shell, while tablets contain enzalutamide in a solid form compressed into a tablet shape. Both capsules and tablets serve the same purpose of delivering enzalutamide to the body for the treatment of prostate cancer. However, some individuals may have preferences or tolerances for one form over the other due to factors such as ease of swallowing or digestion. Ultimately, the choice between capsules and tablets for enzalutamide is based on individual patient needs and preferences, and should be discussed with a healthcare provider.
