Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists are a group of medications that disrupt the movement of calcium (Ca²⁺) through calcium channels. Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension. CCBs are particularly effective against large vessel stiffness, one of the common causes of elevated systolic blood pressure in elderly patients. Calcium channel blockers are also frequently used to alter heart rate (especially from atrial fibrillation), to prevent peripheral and cerebral vasospasm, and to reduce chest pain caused by angina pectoris.
The present invention is related to methods of treating cardiac arrhythmia, angina, or a migraine in a patient in need thereof, with a therapeutically effective amount of a compound having a structure according to the formula:the method comprising nasally administering to the patient (i) a first dose, and (ii) a second dose of an aqueous composition comprising a pharmaceutically acceptable acetate or methanesulfonate salt of compound I, or a racemate or enantiomer thereof, wherein the acetate or methanesulfonate salt of compound I, or the racemate or enantiomer thereof, is dissolved in the aqueous composition at a concentration of 350 mg / mL±50 mg / mL, and wherein the second dose of the compound is administered between 5 minutes and 25 minutes after the first dose.
Provided herein are pharmaceutical compositions comprising a class of calcium channel blockers and at least one chelating agent. More specifically, the pharmaceutical compositions comprise at least one 1,4-dihydropyridine (DHP) compound and at least one chelating agent. The chelating agents used in this disclosure can decrease the degradation of the constituent DHPs of the DHP compositions. The DHP compositions can be used to treat cardiovascular disorders and are more stable for prolonged periods of time.
The present disclosure provides a method for delaying preliminary tumor metastasis. The method involves: (a) preparing a composition containing at least one calciumchannel blocker (CCB), or a pharmaceutically acceptable salt thereof, either alone or in combination with one or more therapeutic compounds; and (b) administering a therapeutically effective amount of the composition, typically in the range of 2-16 mg, to a subject in need. The disclosure particularly pertains to the use of such compositions for delaying tumor metastasis, with Amlodipine being the most preferred calciumchannel blocker in the formulation.
