The present invention provides a pharmaceutical composition for oral administration comprising dihydropyridine calcium channel blocker, such as nisoldipine and one or more release controlling polymer, which is selected from various hydrophilic polymers or combinations thereof. The said polymer is present at a concentration of about 1% to about 60% by weight of the tablet, preferably from about 10% to about 40% by weight of the tablet. The said formulation may also contain one or more adjuvants, which, in combination with the polymeric materials, may help to further modulate the release of nisoldipine.
