Abstract: Methods for treating diabetes mellitus and related conditions and symptoms are described. The methods are directed to administering a therapeutically effective amount of a compound. Compounds suitable for the invention include pyridoxal-5?-phosphate, pyridoxal, pyridoxamine, pyridoxine, a 3-acylated pyridoxal analogue, a pharmaceutically acceptable acid addition salt thereof, or a mixture thereof. Also disclosed are methods directed to concurrently administering a therapeutically effective amount of a compound with other compounds known in the treatment of diabetes mellitus. In one embodiment, a therapeutically effective amount of a compound is administered concurrently with a therapeutically effective amount of insulin. In another embodiment, a therapeutically effective amount of a compound is administered concurrently with a therapeutically effective amount of a hypoglycemic compound.

Abstract: Pyridoxal analogues can be useful for treating B6 deficiency and related diseases; cardiovascular and related diseases; melanoma and related diseases; and symptoms thereof. One such analogue is a compound of the formula: or a pharmaceutically acceptable acid addition salt thereof, in which R1 is alkyl, alkenyl, in which alkyl or alkenyl can be interrupted by nitrogen, oxygen, or sulfur, and can be substituted at the terminal carbon by hydroxy, alkoxy, alkanoyloxy, alkanoyloxyaryl, alkoxyalkanoyl, alkoxycarbonyl, or dialkylcarbamoyloxy; alkoxy; dialkylamino; alkanoyloxy; alkanoyloxyaryl; alkoxyalkanoyl; alkoxycarbonyl; dialkylcarbamoyloxy; or aryl, aryloxy, arylthio, or aralkyl, in which aryl can be substituted by alkyl, alkoxy, amino, hydroxy, halo, nito, or alkanoyloxy. These analogues can be administered, either alone or concurrently with known medications, to treat the above-described diseases.

Abstract: Hypertension in mammalian patients, especially elderly human patients, derived from ingestion of NSAIDs or through the normal aging process is treated by administration to the patient of a vitamin B.sub.6 (or derivative) supplement. Where the patient requires the continued administration of an NSAID for pharmacological purposes, the NSAID is administered in conjunction with a vitamin B.sub.6 supplement. The invention further provides combination pharmaceutical combinations of an NSAID and a vitamin B.sub.6 supplement, e.g. orally administrable tablets or capsules, for use in treating such conditions.

Abstract: Compositions and methods for treatment and prevention of hypertrophy, hypertension, congestive heart failure, ischemic heart disease, ischemia-related conditions, such as ischemia reperfusion injury and cellular dysfunction, are described. The methods are directed to administering pharmaceutical compositions containing at least one compound selected from pyridoxal-5'-phosphate, pyridoxine, pyridoxal, and pyridoxamine.
