The normal dosage of 10 grains (648 mg.) of aspirin, when combined with about 5 to 15, preferably about 10, grains of acetaminophen, yields increased blood levels of unhydrolyzed aspirin shortly and for extended periods after oral ingestion; a small addition of caffeine enables attainment of still higher blood levels of aspirin.
To stabilize the active ingredients, a caffeine is incorporated into a solid pharmaceutical preparation comprising a dextromethorphan and a phenylpropanolamine. The pharmaceutical preparation may further comprise ibuprofen. The active ingredients may be further stabilized, in combination with the incorporation of the caffeine, by grouping and incorporating separately each or suitably combined plural of the active ingredients into different groups or by minimizing the amount of any reducing sugar such as lactose. The solid pharmaceutical preparation is practically valuable since decomposition of each active ingredient with the lapse of time is remarkably suppressed and the active ingredients are stabilized for a longer period of time.
The anti-inflammatory activity of indomethacin, indoxole, and other indole-based drugs is enhanced by administration thereof in conjunction with a phosphonate compound such as EHDP or Cl.sub.2 MDP.
The anti-inflammatory activity of aspirin and other salicylate-based, anti-inflammatory drugs is enhanced by administration thereof in conjunction with a phosphonate compound such as EHDP or Cl.sub.2 MDP.
A composition for the treatment and prevention of endothelial dysfunction comprising a therapeutically effective amount of anti-inflammatory agents comprising; acetylsalicylic acid, an amino sugar and a zinc compound.
