Abstract: Substituted imidazolyl-alkyl-piperazine and diazepine derivatives of Formula A: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, m, n and q are defined as in the specification, and the pharmaceutically acceptable salts thereof. The compounds have calcium entry blocking activity with selectivity for cerebral blood vessels, and have protective activity against some of the deleterious effects resultant upon cerebral ischemia.

Abstract: Substituted imidazolyl-alkyl-piperazine and diazepine derivatives and the pharmaceutically acceptable salts thereof are useful for treating mammals having any of a variety of disease states. These disease states include: 1) diseases treated by direct neuronal protection, including focal and global ischemia, spinal injuries, and head trauma, and neurological diseases including Alzheimer's and Huntington's chorea; 2) uraemic and hyponatraemic encephalopathy; 3) diseases treated by diuresis; 4) diseases treated by calcium channel antagonism, including cardiovascular diseases (i.e. hypertension, angina, stable and unstable angina, Prinzmetal angina, arrhythmia, thrombosis, embolism, and congestive heart failure including chronic or acute cardiac failure), diseases characterized by ischemia of lower legs due to peripheral vascular disease (e.g., intermittent claudication), diseases characterized by spasms of smooth muscle (i.e.

Abstract: There is disclosed an improved long acting sustained release pharmaceutical composition for dihydropyridine calcium channel blockers wherein the calcium channel blocker and a pH-dependent binder, which are intimately admixed in essentially spherically shaped non-rugose particles of up to 1.2 mm in diameter, are provided with a coating to obtain slow, sustained release of a safe, therapeutically effective amount of the calcium channel blocker over a period of at least about 24 hours. Thus, the improved pharmaceutical composition for a dihydropyridine calcium channel blockers is suitable for once daily administration.
