Agonist-anatagonist combination to reduce the use of nicotine and other drugs

A method of treating and reducing a drug dependency such as a nicotine dependency is provided. The method comprises initially administering to a subject a drug, such as nicotine or another agonist of the drug in an amount which would normally provide the desired pharmacologic effects and at least partially satiate the needs for the drug by a user. The method also comprises administering to the subject an antagonist to the drug or its other agonist in an amount sufficient to at least partially block the pharmacologic defects of the drug or its other agonist while there is a substantial amount of the drug or other agonist present in the system of the user. In one embodiment of the invention, the drug and the antagonist are administered substantially simultaneously so as to occupy a substantial portion of the receptors of the user for that drug thereby blocking or attenuating the effects of any further intake of the drug or other agonist. In another embodiment, the drug or its other agonist is first administered and the antagonist is self-administered by a subject in a manner which mimics the use of the drug thereby counter-conditioning the drug user to the stimuli associated with the normal administration of the drug. The invention further provides a method of therapeutically treating psychophysiologic diseases and disorders involving neuronal dysregulation. The method additionally provides a pharmacologic composition for the treatment and reduction of drug dependence and which relies upon a combination of an agonist and antagonist.

Cholesterol-uptake-blocking drugs inhibit angiogenesis and are useful to inhibit diseases perpetuated by angiogenesis. Cholesterol reduction with the use of the drugs increases the intratumoral level of thrombospondin-1, an angiogenesis inhibitor. Ezetimibe (Zetia®), a specific cholesterol-uptake blocking drug, also retards the growth of human tumors, most preferably in combination with low-cholesterol diet. The pharmacologic reduction in serum cholesterol retards prostate cancer growth by inhibiting tumor angiogenesis to combat the growth of prostatic tumors which are directly accelerated by hypercholesterolemia.
