There is no clear first-line tocolytic agent. [6] [7] Current evidence suggests that first line treatment with β 2 agonists, calcium channel blockers, or NSAIDs to prolong pregnancy for up to 48 hours is the best course of action to allow time for glucocorticoid administration.
In general, a-methyldopa, β-blockers and calcium channel blockers are the first or second treatment line for hypertension during pregnancy. However, ACEis, ARBs and diuretics are mostly contraindicated, as the potential risk outweighs the benefits of their administration.
A 2014 systematic review by the Cochrane Collaboration showed that while atosiban had fewer side effects than alternative drugs (such as ritodrine), other beta blockers, and calcium channel antagonists, it was no better than placebo in the major outcomes i.e. pregnancy prolongation or neonatal outcomes. The finding of an increase in infant ...
Flunarizine is a selective calcium antagonist with moderate other actions including antihistamine, serotonin receptor blocking and dopamine D 2 blocking activity. Compared to other calcium channel blockers such as dihydropyridine derivatives, verapamil and diltiazem, flunarizine has low affinity to voltage-dependent calcium channels.
Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists [2] are a group of medications that disrupt the movement of calcium (Ca 2+) through calcium channels. [3] Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension.
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.

Amlodipine is an angioselective calcium channel blocker and inhibits the movement of calcium ions into vascular smooth muscle cells and cardiac muscle cells which inhibits the contraction of cardiac muscle and vascular smooth muscle cells. Amlodipine inhibits calcium ion influx across cell membranes, with a greater effect on vascular smooth ...
Verapamil is also a Kv voltage gated potassium channel blocker. [37] Calcium channels are also present in the smooth muscle lining blood vessels. By relaxing the tone of this smooth muscle, calcium channel blockers dilate the blood vessels. This has led to their use in treating high blood pressure and angina pectoris. The pain of angina is ...
