Abstract
Pharmaceutical formulations comprising as active ingredients an angiotensin-II receptor (A-II) antagonist at a dose level normally found effective as an antihypertensive and a diuretic at a dose level below its minimum effective dose, demonstrate greater efficacy than would be expected in returning the blood pressure of hypertensive patients to normotensive values.

TITLE OF THE INVENTION
COMBINATIONS OF ANGIOTENSIN-II RECEPTOR
ANTAGONISTS AND DIURETICS
- BACKGROUND OF THE INVENTION
Both diuretics and A-II antagonists have an effect on the renin-angiotensin-aldosterone system. A-II antagonists lower blood pressure by blocking the angiotensin II receptors important in regulating blood pressure. Diuretics regulate the sodium-balance, and
10 thereby also extracellular fluid volume. The resultant decrease, both in sodium and fluid volume, following therapy with diuretics activates the renin-angiotensin-aldosterone system. This compensatory response will, to some degree, counteract the blood-pressure lowering effect of the diuretic. When a diuretic and an A-II antagonist are combined the
15 different pharmacological actions ofthese two drugs will, influence the effect of the other. There is accordingly a logical rationale for combining these two pharmacological agents.
It is possible to establish the highest non-pharmacological active dose of diuretic, i.e. a dose that is so low that it has essentially no
20 effect on blood pressure, and no apparent adverse effects. The clinically non-effective dose of diuretic, however, will still activate the renin-angiotensin-aldosterone system and although it has no effect on blood pressure, it will, nonetheless, have a potentiating effect on an A-II antagonist action in lowering blood pressure.
25 In a recently completed study of the effects of different doses of HCTZ on blood pressure and various metabolic parameters, doses ranging from 3 mg to 25 mg were investigated. 25 mg HCTZ produced significant effects on blood pressure and the metabolic parameters. 12.5 mg of HCTZ was at the threshold of an effective
3 ° antihypertensive response, and this dose also altered metabolic parameters. In contrast, HCTZ at 3 and 6 mg were not different from placebo in terms of blood pressure and metabolic end-points.
Based on this study it can be concluded that the 6 mg or 6.25 mg dose is close to the highest non-pharmacological dose of HCTZ.
SUMMARY OF THE INVENTION
This invention is concerned with pharmaceutical formulations for the treatment of essential hypertension and disorders associated therewith such as heart failure, cardiac or vascular hypertrophy, renal failure, proteinuria, ischemia or restenosis, which have as active ingredients an A-II antagonist and a diuretic wherein the diuretic is at a dose level below the recognized clinically effective dose. With these formulations the A-II antagonist is found to have greater efficacy in reducing elevated blood pressure to normal levels than it would have if used at the same dose as monotherapy. At the same time the diuretic is being administered at dose levels that would be ineffective as an antihypertensive if used alone and similarly ineffective in causing adverse reactions.
DETAILED DESCRIPTION OF THE INVENTION
The novel pharmaceutical formulations of this invention comprise: a pharmaceutical carrier; an A-II antagonist at the dose level normally employed in monotherapy, which is usually about 0.1 to about 1000 mg preferably about 1-100 mg, depending on the A-II antagonist; and a diuretic at a dose level which is the highest non-pharmacological dose.
The formulation is designed for oral administration and is presented as tablets, capsules, gel caps, caplets, sublingual dosage form or as a sustained release formulation. It may also be designed as an elixir for oral administration, a suppository for rectal administration, or a patch for transdermal administration, or a biodegradable stint for local intraarterial administration.
Illustrative of the excipients which can be incorporated in tablets, capsules and the like are: a binder such as gum tragacanth, acacia, com starch or gelatin; an excipient such as microcrystalline cellulose; a disintegrating agent such as com starch, pregelatinized starch, alginic acid and the like; a lubricant such as magnesium stearate; a sweetening agent such as sucrose, lactose or saccharin; a flavoring
agent such as peppermint, oil of wintergreen or cherry. When the unit dosage form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier such as fatty oil. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets may be coated with shellac, sugar or both. A syrup or elixir may contain the active compound, sucrose as a sweetening agent, methyl and propyl parabens as preservatives, a dye and a flavoring such as cherry or orange flavor.
The novel formulations of this invention are useful in the treatment of essential hypertension, and heart failure, cardiac or vascular hypertrophy, renal failure, proteinuria, ischemia or restenosis.
Typical of the A-II antagonists useful in the novel formulation and method of treatment of this invention are the following compounds I through XI:

Preferred diuretics for incorporation in the novel formulation of this invention are hydrochlorothiazide, trichlormethazide, furosemide, chlorthalidone, and altizide, especially hydrochlorothiazide.
In the specification and claims hereof, the naming of an A- II antagonist or diuretic such as losartan or hydrochlorothiazide respectfully is meant to include salts thereof.
The novel method of treatment of this invention comprises the administration of a unit dose of the novel pharmaceutical formulation, one to three times a day depending on the patient and the severity of the indication being treated. Usually once or twice a day is adequate.
