Description
FIELD OF THE INVENTION:
The invention relates to the preparation of a combination product consisting of ACE inhibitor such as Ramipril, Benazapril etc., and beta-blocker compound such as Carvedilol, Propronalol etc. This combination product will result in better compliance; reduce the frequency of administration, and overall reduction in medication costs.
BACKGROUND OF THE INVENTION:
Cardiovascular diseases (CVDs) are the disorders of heart and blood vessels and primarily include coronary heart disease, hypertension, cerebrovascular disease, peripheral artery disease, rheumatic heart disease, congenital heart disease and heart failure. CVDs are the major cause of death in developed countries and also are rapidly emerging as a main cause of death in the developing world. An estimated 17.5 million people died from CVDs till 2005, representing almost 30% of all global deaths. It is projected that almost 20 million people will die from CVDs by 2015. CVDs affect many people in middle age, very often severely limiting the income and savings of the affected individuals. Lost earnings and unaffordable health care expenditures undermine the socioeconomic development of communities and nations [1,2] (also see http://www. who.int/cardiovascular_diseases/en/ and http://www.who.int/mediacentre/factsheets/fs317/en/index.htmn.
In treating these cardiovascular diseases, especially hypertension and congestive heart failure, Ramipril, an angiotensin-converting enzyme (ACE) inhibitor, is used. It is also used following myocardial infarction in patients with clinical evidence of heart failure, prevention of myocardial infarction, stroke, cardiovascular death or need of revascularization procedures, and diabetic nephropathy with microalbuminuria. It is a derivative of 2-aza-bicyclo [3,3,0]-octane-3-carboxylic acid, and physically available as a white crystalline solid. It is soluble in polar organic solvents and buffered aqueous solutions.
Carvedilol is a non-selective beta blocker/alpha-1 blocker, used in the treatment of mild to moderate congestive heart failure, and is usually used as an adjunct to conventional treatments with ACE inhibitors and diuretics. Chemically, Carvedilol is (±)-l -(Carbazol-4-yloxy)-3-[[2-(0-methoxyphenoxy)ethyl]amino]-2-propanol. It is
available as a white to off-white powder. Carvedilol is practically insoluble in water, gastric fluid (pH 1.1), and intestinal fluid (pH 7.5).
Current hypertension treatment guidelines recommend a goal of <140/90 mmHg for population with uncomplicated hypertension and goals are even lower (< 130/80 mmHg) for patients with diabetes or renal disease. These recommendations are supported by long-term trials suggesting that the greater the reduction in Blood Pressure, the greater the reduction in risk of cardiovascular events. Major clinical studies have shown that most patients require two or more drugs to achieve their Blood Pressure goals. Combination therapy should be used as initial treatment for patients in whom the probability of achieving Blood Pressure control with monotherapy is low.
The current drug therapy for treating congestive heart failure and hypertension quite often include a combination of ACE inhibitor and beta blocker such as Ramipril and Carvedilol that are available as separate dosage forms. Even though ACE inhibitor and diuretic combinations are available, a combination of ACE inhibitors and Beta/Alpha blockers are not available because beta blocker such as Ramipril has been reported to interact with many commonly used excipients such as pregelatinized starch, lactose, microcrystalline cellulose, colloidal silicon dioxide, crospovidone, magnesium stearate, and methacrylic acid copolymers (Reference: US Patent Application #20060045911, Point # 0013) and other active ingredients like Carvedilol. Carvedilol is practically insoluble in water. Under in vivo conditions, it shows site specific absorption in stomach, and undergoes extensive first pass metabolism (25-35% oral bioavailability), and hence, the bioequivalence risk is higher. In addition, Carvedilol exhibit food effects, where food reduces its rate of absorption.
Currently ACE inhibitors are prescribed for concomitant administration as Altace capsules and beta-blocker compounds such as Carvedilol are available as separate products. No combination products of these two classes of compounds are available in the market or combination information is available.
SUMMARY OF THE INVENTION:
The invention is to prepare a combination product consisting of ACE inhibitor such as
Ramipril, Benazapril etc., and beta-blocker compound such as Carvedilol, Propronalol etc. This combination product will result in better compliance; reduce the frequency
of administration, and overall reduction in medication costs. The overarching benefit is in better efficacy outcomes in hypertensive and congestive heart failure treatments.
This invention relates to a pharmaceutical preparation for oral administration comprising a combination of a) an ACE inhibitor such as Ramipril, benzapril or a pharmaceutically acceptable salt thereof, and b) a non selective Beta-blocker such as Carvedilol, propranolol etc, or a pharmaceutically acceptable salt thereof, wherein
1) the ACE inhibitor compound is in immediate release form,
2) the beta-blocker compound is in immediate release form and,
3) the combination is in a solid fixed-unit dosage form such as a capsule or a tablet.
BRIEF DESCRIPTION OF THE DRAWINGS
The following are the schematics (1 to 4) that represent combination products, where in the Carvedilol component is coated with pharmaceutical excipients such as maltodextrin, aglinic acid, sodium alginate, etc, or separated from Ramipril by an inert layer. The Ramipril component is blended with pharmaceutical excipients such as sucrose, maltodextrin etc. Both components are finally enclosed in a capsule or compressed into a tablet. The resulting formulations exhibit dissolution profiles comparable to commercially available individual products as shown in Figure 1. Figure 1 : Schematic 1.
