Hello! Thank you for asking on HCM! Regarding your concern, I would explain that both drugs help to lower high blood pressure. Temla is an angiotensin receptor blocker, while Betacap id a beta-blocker. Facing your young age and possible implication of therapy to physical performance, I would recommend Templa, which offers a better hemodynamic profile, if no contraindications exist. nevertheless, there are many several options for high BP treatment. You need to discuss with your doctor about your past medical history implications in deciding the most safety profile treatment. Hope to have been helpful to you. Greetings!
