Title: Methods and compositions for noninvasive dose-to-effect administration of drugs with cardiovascular or renal vascular activities
Abstract:The present invention is directed to methods and compositions for noninvasively administering drugs in a dose-to-effect manner to produce a cardiovascular or renal vascular activity. A cardiovascular or renal vascular drug, which is capable of absorption through mucosal tissues of the mouth, pharnyx, and esophagus is incorporated into a matrix which is in the form of a lollipop. A patient is put at ease when given the lollipop, and the drug rapidly enters the patient's bloodstream as the lollipop is sucked. When treating the patient, the physician can observe the patient's condition and remove the lollipop when it has had a desired effect on the patient. A lollipop into which a cardiovascular or renal vascular drug has been dispersed is particularly useful for achieving rapid vasodilating, calcium channel blocking, beta-blocking, seritonin receptor blocking, angina blocking, antihypertensive, and cardiac stimulating effects and for controlling urine output.

lipophilic drug means for inducing a predetermined systemic modification of cardiovascular functions in the patient that can be observed before overdosage in the patient occurs;

carbohydrate releasing means, the releasing means uniformly incorporating said drug means, for simultaneously releasing said drug means over a period of time as the releasing means is dissolved while being sucked and held passively in the mouth of the patient for substantially complete administration via absorption through mucosal tissues of the mouth, pharynx, and esophagus in a dose-to-effect manner such that systemic modification of cardiovascular functions is achieved and maintained; and

a stick secured to the releasing means, for permitting convenient insertion of the releasing means into the mouth of the patient, and for quantitatively and conveniently permitting insertion and removal of the releasing means in response to the observed effect of the drug means on the patient in order to maintain a desired effect over a prolonged period of time in response to susceptibility and needs of an individual patient, the stick remaining after the releasing means has completely dissolved.

2. A composition as defined in claim 1, wherein the stick means is a stick with an enlarged end to prevent the stick from getting caught in the patient's mouth.

3. A composition as defined in claim 1, wherein the drug means comprises an antiarrhythmic drug.

4. A composition as defined in claim 1, wherein the drug means comprises a hypotensive drug.

7. A composition as defined in claim 1, wherein the drug means comprises an inotropic drug.

8. A composition as defined in claim 5, wherein the vasodilating drug is a calcium channel blocking agent.

9. A composition as defined in claim 5, wherein the vasodilating drug is an organic nitrate.

10. A composition as defined in claim 4, wherein the hypotensive drug is a beta-adrenergic blocking agent.

11. A composition as defined in claim 1, wherein the releasing means comprises an inner carbohydrate matrix containing the drag means in a suitable concentration for maintaining the desired cardiovascular, vasodilating, anti-hypertensive, or anti-anginal effect, and an outer carbohydrate matrix covering the inner matrix, said outer matrix containing the drug means in a suitable concentration for inducing the desired cardiovascular, vasodilating, anti-hypertensive, or anti-anginal effect.

13. A composition as defined in claim 11, wherein the releasing means comprises a flavoring in order to mask the flavor of the drug.

14. A composition as defined in claim 1, wherein the releasing means includes a hydrophobic material such that the releasing means becomes less soluble when placed in the patient's mouth.

15. A composition as defined in claim 1, wherein the releasing means includes a coloring agent.

16. A composition as defined in claim 1, wherein the stick means is secured to the releasing means by compressing the releasing means around a portion of the stick means such that the releasing means remains cohesively secured to the stick means.

17. A composition as defined in claim 1, wherein the drug means is lipophilic.

18. A composition as defined in claim 1, wherein the drug means is potent and fast-acting.

19. A composition as defined in claim 1, wherein the releasing means comprises a soluble matrix material, the drug means being dispersed substantially uniformly within the matrix.

20. A composition as defined in claim 1, wherein the ratio of the drug means to the releasing means may be varied in order to vary the rate of uptake of the drug means by the body.

21. A composition for use in inducing a predetermined systemic modification of cardiovascular functions in a patient, said composition comprising:
