Based on "Treatment of Myocardial Ischemia and Hypertension" written by Thomas Michel, MD, Ph D, and Brian B. Hoffman, MD This comprehensive listing includes therapeutic agents that can be used for lowering of blood pressure. Alpha blockers, also called alpha-adrenergic antagonists, dilate blood vessels by blocking postsynaptic alpha1-adrenergic receptors. Alpha blockers are generally not recommended as initial therapy. ACE inhibitors remain the initial treatment of choice for hypertension. This class of drugs blocks the conversion of angiotensin I to angiotensin II by inhibiting angiotensin-converting enzyme (ACE), thus preventing constriction of blood vessels. Beta-blockers produce antihypertensive action by reducing heart rate and cardiac output. Metoprololo è un inibitore selettivo (β-bloccante) dei recettori adrenergici β1: la molecola blocca in modo competitivo i β1-recettori con effetti nulli o scarsi sui β2-recettori per dosaggi inferiori a 100 mg. A dosaggi più elevati anche i recettori β2 iniziano a subire l'effetto inibitorio e la selettività viene via via riducendosi. Il metoprololo è sostanzialmente privo di effetto stabilizzante di membrana e non mostra attività intrinseca simpaticomimetica. Come è noto i β1-recettori adrenergici sono presenti principalmente a livello cardiaco e renale e la loro inibizione da parte di metoprololo determina a livello cardiaco un effetto inotropo e cronotropo negativo, ovvero una riduzione della frequenza cardiaca, della gittata cardiaca e della contrattilità cardiaca. Tutti questi effetti comportano, in ultima analisi, una riduzione del lavoro del cuore. Il farmaco determina una riduzione della pressione arteriosa e nei soggetti affetti da angina pectoris comporta un miglioramento della tolleranza agli sforzi. Studi clinici effettuati su una popolazione di soggetti di sesso maschile con ipertensione arteriosa da lieve a moderata, hanno messo in evidenza che il β-bloccante riduce il rischio di morte per malattie cardiovascolari.

I get hot flashes, shakes, tingling arms, a general feeling of panic when I see my reading is low or I feel the shakes.... But i chose to take my drs orders instead - mostly bc as someone who constantly monitors my Bp and hr, I don't find it necessary to take twice a day. And with my anxiety disorder I am taking my blood pressure every hour. But dealing with the metoprolol, it has dropped me to 88/55 at times, today 112/73, then 93/55 then 142/70. And of course knowing they gave me this to lower my heart rate makes me nervous. pills of each medication, you are loosing a great deal of the latter drug's effectiveness as the day wears on. I find the fact that I occasionally forget to take my medications sort of resets my residual levels to near zero... My heart rate stats around 70 and my Bp stays around 100/70 all day, I find no need to introduce even more of a drug into my body when I've been on the metrication for quite some time with normal readings when only taking it once every 24 hr....

Based on evidence-based guidelines for pharmacologic treatment for episodic migraine prevention in adults from the American Academy of Neurology and the American Headache Society, metoprolol is effective for migraine prevention in adults. Based on the American College of Cardiology/American Heart Association/Heart Rhythm Society (ACC/AHA/HRS) guidelines for the management of adult patients with supraventricular tachycardia, the use of an oral or intravenous beta-blocker, including metoprolol, is effective and recommended for a variety of symptomatic supraventricular tachycardias (atrioventricular nodal reentrant tachycardia [AVNRT], atrioventricular reentrant tachycardia [AVRT], focal atrial tachycardia [AT], and multifocal atrial tachycardia [MAT]). In patients without pre-excitation, intravenous metoprolol is recommended for acute treatment in hemodynamically stable patients and oral metoprolol is recommended for ongoing management of symptomatic supraventricular tachycardias in patients who are not candidates for, or prefer not to undergo, catheter ablation. Intravenous or oral metoprolol may be useful for rate control in the acute treatment or ongoing management of hemodynamically stable patients with atrial flutter. Based on the American Thyroid Association guidelines for diagnosis and management of hyperthyroidism and other causes of thyrotoxicosis, beta-blockers, including metoprolol, are effective and recommended in the treatment of symptomatic thyrotoxicosis.

I've taken a double dose on many occasions to aid conversion of SVT episodes.
