Med student here.
Be careful by the suggestions in this thread. DO NOT go out and buy the medicines these guys are suggesting. When prescribing antihypertensives, physcians take into account many factors when figuring out what drug to give a patient.
Current protocol for a young guy like you (actually, you never told us your age but i'll assume here) would be first to assess diet and lower Na intake. If medications are necessary, first line therapy here is to start with a Thiazide diuertic. Using an ACEI or ARB is only first line thereapy in hypertensive patients with chronic renal disease. However, ACEI and ARBs are second line treatments for patients who need more than a thiazide diuretic. Third line therapy would be to add a calcium channel blocker in there and fourth line is adding a beta blocker.
One poster suggested you take atenolol (because his mother took it). Beta blockers are only first line therapy in patients with coronary atery disease or congestive heart failure. So, not a bright idea for you to start taking beta blockers since you're not in that population.
Another reason not to just start ordering drugs for yourself are the side effects and each drug has to be taken carefully under the supervision of a physcian. As many posters mentioned, ACEIs and ARBs cause hyperkalemia (high K+) in addition to dry cough and angioedema. Thiazide duiertics cause hypokalemia (low K+), postive calcium balance, and some glucose intolerance. They are often taken together to compensate for K disturbances. Beta blockers can cause bronchospasm. Notice the poster never asked you if you had asthma. You take a beta blocker with asthma and you could kill yourself.
The point I'm trying to make here is that the control of hypertension takes into account many factors and for the most part, therapy is geared more towards the needs of the paitent. Therefore, you can't just start some medication because someone on this board told you his mom uses a beta blocker or a poster uses an ACEI/ARB. Antihypertensives cause a variety of metabolic and electrolyte disturbances that need to be monitored by a physcian.
