Description: TITLE OF THE INVENTION BUCCAL POLAR SPRAY OR CAPSULE BACKGROUND OF THE INVENTION It is known that certain biologically active compounds are better absorbed through the oral mucosa than through other routes of administration, such as through the stomach or intestine. However, formulations suitable for such administration by these latter routes present their own problems. For example, the biologically active compound must be compatible with the other components of the composition such as propellents, solvents, etc. Many such formulations have been proposed. For example, U.S. P. 4,689,233, Dvorsky el aL, describes a soft gelatin capsule for the administration of the anti-coronary drug nifedipine dissolved in a mixture of polyether alcohols. U.S. P. 4,755,389, Jones et aj., describes a hard gelatin chewable capsule containing nifedipine. A chewable gelatin capsule containing a solution or dispersion of a drug is described in U.S. P. 4,935,243, Borkan et aj. U.S. P. 4,919,919, Aouda el aj, and U.S. P. 5,370,862, Klokkers-Bethke, describe a nitroglycerin spray for administration to the oral mucosa comprising nitroglycerin, ethanol, and other components. An orally administered pump spray is described by Cholcha in U.S. P. 5, 186,925. Aerosol compositions containing a hydro¬ carbon propellant and a drug for administration to a mucosal surface are described in U.K. 2,082,457, Su, U.S. P. 3, 155,574, Silson fil gj., U.S. P. 5,01 1 ,678, Wang et aj., and by Parnell in U.S. P. 5, 128, 132. It should be noted that these references discuss bioavailability of solutions by inhalation rather than through the membranes to which they are administered. SUMMARY OF THE INVENTION A buccal aerosol spray or soft bite gelatin capsule using a polar solvent has now been developed which provides biologically active com¬ pounds for rapid absorption through the oral mucosa, resulting in fast onset of effect. The buccal aerosol spray compositions of the present invention, for transmucosal administration of a pharmacologically active compound soluble in a pharmacologically acceptable polar solvent comprising in weight% of total composition: polar solvent 75-99.8%, active compound 0.0025-40%, suitably additionally comprising, by weight of total composition a flavoring agent 0.05-5%. Preferably the composition comprises: polar solvent 75- 99%, active compound 0.025-20%, flavoring agent 0.1-2.5%; most suitably polar solvent 75-98%, active compound 0.125-12.5%, flavoring agent 0.1-2.5%. The soft bite gelatin capsules of the present invention for trans¬ mucosal administration of a pharmacologically active compound, at least partially soluble in a pharmacologically acceptable polar solvent, having charged thereto a composition comprising in weight % of total composition: polar solvent 40-99.8%, emulsifier 0-20%, active compound 0.0003-35%, provided that said composition contains less than 10% of water, suitably additionally comprising, by weight of the composition: flavoring agent 0.05-60%. Preferably, the soft bite gelatin capsule comprises: polar solvent 50-99.8%, emulsifier 0-15%, active compound 0.0003-26%, flavoring agent 0.5-55%; most suitably: polar solvent 70-99.5%, emulsifier 0-10%, active compound 0.015-24.0%, flavoring agent 0.1-50%. It is an object of the invention to coat the mucosal membranes either with extremely fine droplets of spray containing the active compounds or a solution or paste therof from bite capsules. It is also an object of the invention to administer to a mammalian need of-βame preferably man, a predetermined amount of a biologically active compound by this method or from a soft gelatin bite capsule. A further object is a pump spray container containing a composition of the spray formulation, and a metered valve suitable for releasing from said container a predetermined amount of said composition. The solvent is a low molecular weight, pharmacologically acceptable alcohol, water, glycerine or polyethylene glycol or mixtures thereof. A further object is a soft gelatin bite capsule containing a composition as set forth above. The formulation may be in the form of a viscous solu- tion or paste containing the active compounds. Although solutions are preferred, paste fills may also be used where the active compound is not soluble or only partially soluble in the solvent of choice. Where water is used to form part of the solvent or paste composition, it should not exceed 10% thereof. {All percentages herein are by weight unless otherwise indicated.) The polar solvent is chosen such that it is compatible with the gelatin shell and the active compound. The solvent preferably dissolves the active compound. However, other components wherein the active compound is not soluble or only slightly soluble may be used and will form a paste fill. Soft gelatin capsules are well known in the art. See, for example, U.S. P. 4,935,243, Borkan et al., which is incorporated herein by reference for its teaching of such capsules. The capsules of the present invention are intended to be bitten into to release the low viscosity solution or paste therein, which will then coat the buccal mucosa with the active compounds. Typical capsules, which are swallowed whole or bitten and then swallowed, deliver the active compounds the stomach, which results in significant lag time before maximum blood levels can be achieved or subject the compound ϊo«β large first pass effect. Because of the enhanced absorption of the compounds through the oral mucosa and no chance of a first pass effect, use of the bite capsules of the invention will eliminate much of the lag time, resulting in hastened onset of biological effect. The shell of a soft gelatin capsule of the invention may comprise, for example: gelatine 50-75%, glycerine 20-30%, colorants 0.5-1.5%, water 5-10%, and sorbitol 2-10%. The spray compositions of the invention are intended to be administered from a pump spray. BRIEF DESCRIPTION OF THE DRAWING The figure is a schematic diagram showing routes of absorption and processing of pharmacologically active substances in a mammalian system. DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred active compounds of the present invention are nicotine, clemastine, testosterone, estradiol, progesterone, fluoxetine, and piroxicam in their nonionized form or as the free base of the pharmaceutically acceptable salts thereof (provided, for the aerosol or spray compositions, they are soluble in the spray solvent). These compounds are soluble in the non- polar solvents of the invention at useful concentrations or can be prepared as pastes at useful concentrations. These concentrations may be less than the standard accepted dose for these compounds since there is enhanced absorption of the compounds through the oral mucosa. This aspect of the invention is especially important when there is a large (40-99.99%) First pass effect. As solvents for the sprays there may be used low molecular weight polyethyleneglycols (PEG) of 400-1000 Mw (preferably 400-600). Low molecular weight alcohols and polyols, such as glycerin may also be present and water may also be used. Suitable solvents for the capsules include low molecular weight polyethyleneglycols (PEG) of 400-1000 Mw (preferably 400-600). Low molecular weight alcohols and polyols, such as glycerin may also be present and water may also be used. However, these should only be used sparingly in the bite capsule compo-sitions as they may migrate into the gelatin shell and weaken it. It is expected that some glycerin and water used to make the gelatin shell will migrate from the shell to the fill during the curing of the shell. Likewise, there may be some migration of components from the fill to the shell during curing and even throughout the shelf-life of the capsule. Therefore, the values given herein are for the compositions as prepared, it being within the scope of the invention that minor variations will occur. The preferred flavoring agents are synthetic or natural oil of pepper¬ mint, oil of spearmint, citrus oil, fruit flavors, chocolate, sweeteners (sugars, aspartame, saccharin, etc.), and combinations thereof. The active substances include the active compounds selected from the group consisting of alkaloids, anti histamines, steroid hormones, non- steroidal anti-inflammatories, analgesics and anti-depressants, benzo- diazepines, such as tamezepam. Clemastine hydrogen fumarate is a known (Tavist ® , Sandoz) anti- histamine. Both the spray and capsule of the invention advantageously coat the oral mucosa with an immediately available dose of clemastine which can be rapidly absorbed. This is highly desirable, as during an acute asthma attack. Nicotine is a component of tobacco products which is considered addictive. Smokers wishing to stop smoking have a dual problem. First, is the addictive properties of nicotine itself. Second, is that the habit is associated with smoking activities, i.e., puffing, inhaling, etc. Both the spray and capsule of the invention dissociate these two problems. By presenting nicotine in a form which can be readily absorbed, the spray and capsule allow the smoker to temporarily continue nicotine use but terminate smoking. Once the habit of smoking is stopped, the former smoker can then be weaned off nicotine use, as by less frequent use and/or by use of a lower concentration spray or capsule. Advantageously, during this regimen, the user is exposed to none of the carcinogens present in tobacco smoke. Testosterone is a hormone produced by gonadal cells. Testosterone, especially the esters thereof (e.g., acetate, propionate, enanthate, and cypionate), is used in the treatment of hypogonadism. Estradiol is an estrogen steroid secreted from the ovaries. Estradiol, especially the esters thereof (e.g., diacetate, and benzoate), is used as estrogen replacement therapy, especially in post-menopausal women. Progesterone is a hormone produced by the corpus luteum. Fluo¬ xetine is an antidepressant also known as Prozac. Piroxicam is a known (Feldene ® , Pfizer) anti-inflammatory. The formulations of the present invention comprise an active com¬ pound or a pharmaceutically acceptable salt thereof. The term "pharmaceutically acceptable salts" refers to salts prepared from pharmaceutically acceptable non-toxic acids or bases including organic and inorganic acids or bases. When an active compound of the present invention is acidic, salts may be prepared from pharmaceutically acceptable non-toxic bases. Salts derived from all stable forms of inorganic bases include aluminum, .aiwnonium, calcium, copper, iron, lithium, magnesium, manganese, potassium, sodium, zinc, etc. Particularly preferred are the ammonium, calcium, magnesium, potassium, and sodium salts. Salts derived from pharmaceutically acceptable organic non-toxic bases include salts of primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion- exchange resins such as arginine, betaine, caffeine, choline, N,N'- dibenzylethylenediamine, diethylamine, 2-diethylaminoethanol, 2-dimethyl¬ aminoethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N-ethyl- piperidine, glucamine, glucosamine, histidine, isopropγlamine, lysine, methylglucosamine, morpholine, piperazine, piperidine, polyamine resins, procaine, purine, theobromine, triethylamine, trimethylamine, tripropylamine, etc. When an active compound of the present invention is basic, salts may be prepared from pharmaceutically acceptable non-toxic acids. Such acids include acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethane- sulfonic, fumaric, gluconic, glutamic, hydrobromic, hydrochloric, isethionic, lactic, maleic, mandelic, methanesulfonic, mucic, nitric, pamoic, panto- thenic, phosphoric, succinic, sulfuric, tartaric, p-toluenesulfonic, etc. Particularly preferred are citric, hydrobromic, maleic, phosphoric, sulfuric, and tartaric acids. In the discussion of methods of treatment herein, reference to the active compounds is meant to also include the pharmaceutically acceptable salts thereof. While certain formulations are set forth herein, the actual amounts to be administered to the mammal or man in need of same are to be determined by the treating physician.
