Nifedipine is a drug belonging to a class of pharmacological agents known as the calcium channel blockers. Nifedipine is 3,5-pyridinedicarboxylic acid, 1,4-dihydro-2,6-dimethyl-4-(2-nitrophenyl)-, dimethyl ester, C 17 H 18 N 2 O 6 , and has the structural formula: Nifedipine is a yellow crystalline substance, practically insoluble in water but soluble in ethanol. It has a molecular weight of 346.3. Nifedipine GITS (Gastrointestinal Therapeutic System) tablet is formulated as a once-a-day controlled-release tablet for oral administration designed to deliver 30, 60, or 90 mg of nifedipine. Inert ingredients in the formulations are: cellulose acetate; ferric oxide; hypromellose; magnesium stearate; polyethylene glycol; polyethylene oxide; potassium chloride; povidone; sodium chloride; titanium dioxide; propylene glycol and black iron oxide. The USP Dissolution Test is pending. System Components and Performance Nifedipine extended-release tablets are similar in appearance to a conventional tablet. It consists, however, of a semipermeable membrane surrounding an osmotically active drug core. The core itself is divided into two layers: an “active” layer containing the drug, and a “push” layer containing pharmacologically inert (but osmotically active) components. As water from the gastrointestinal tract enters the tablet, pressure increases in the osmotic layer and “pushes” against the drug layer, releasing drug through the precision laser-drilled tablet orifice in the active layer. Nifedipine extended-release tablets are designed to provide nifedipine at an approximately constant rate over 24 hours. This controlled rate of drug delivery into the gastrointestinal lumen is independent of pH or gastrointestinal motility. Nifedipine extended-release tablets depend for its action on the existence of an osmotic gradient between the contents of the bi-layer core and fluid in the gastrointestinal tract. Drug delivery is essentially constant as long as the osmotic gradient remains constant, and then gradually falls to zero. Upon swallowing, the biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the feces as an insoluble shell. structure

Inert ingredients in the nifedipine extended-release tablet formulation are lactose monohydrate, microcrystalline cellulose, hypromellose, hydroxyethyl cellulose, ethylcellulose, sodium lauryl sulfate, magnesium stearate, methacrylic acid and methyl methacrylate copolymer, polyethylene glycol, talc, polyvinyl alcohol, titanium dioxide (30mg and 60mg), iron oxide yellow, iron oxide red, lecithin (soya) (30 mg and 90 mg), iron oxide black (30 mg and 90 mg). System Components and Performance Nifedipine extended-release tablet is designed for once-a-day oral administration. The extended-release tablet uses two release-rate controlling mechanisms: a primary polymer matrix core composed of drug with excipients and a secondary enteric coating surrounding the core. Upon swallowing, water is taken up through the enteric coating membrane into the primary core matrix, and the enteric coating membrane will dissolve at rising gastrointestinal pH value, which in turn slowly releases the drug from the formulation.
