Abstract: This invention relates to stable pharmaceutical compositions of 5,10-methylene-(6R)-, -(65)- or -(6R,S)-tetrahydrofolate by adjusting to a basic pH and the simultaneous use of citrate. Stabilisation is effected even in the absence of a reducing agent. The present invention is particularly suitable for producing lyophilisation solutions and lyophilisates or dry powders and dry mixtures, since the stable MTHF solutions can be used in high concentrations for filling corresponding vessels such as phials, ampoules, etc. The lyophilisates have a surprisingly long shelf life and are surprisingly stable. They can be reconstituted without problems by adding water or aqueous solutions, and the final clear injection solutions again exhibit excellent stability properties. Moreover, the present invention even makes it possible to prepare difficultly soluble calcium or acidic salts of MTHF in high concentrations and as physiologically compatible isotonic solutions.

Abstract: The present invention relates to a pharmaceutical composition which may comprise progestogens, preferably drospirenone, estrogens, preferably ethinylestradiol and 5-methyl-(6S)-tetrahydrofolate, which may be employed as oral contraceptive and moreover prevents disorders caused by folate deficiency in the consumers, in particular cardiovascular disorders and, after conception of the embryo, congenital malformations caused by folate deficiency such as, for example, neural tube defects, ventricular valve defects, urogenital defects, and cleft lip, jaw and palate, without masking the symptoms of vitamin B12 deficiency, and at the same time even in the case of homozygous or heterozygous polymorphism of methylenetetrahydrofolate reductase facilitates unimpaired utilizability of the folate component 5-methyl-(6S)-tetrahydrofolate by the body and thus its biological activity for preventing the abovementioned congenital malformations caused by folate deficiency.

Abstract: This invention relates to the use of folates for producing a pharmaceutical preparation suitable for the prevention and treatment of inflammation and of diseases associated with inflammation, particularly for influencing the inflammation markers C-reactive protein (CRP) and serum amyloid A protein (SAA). The clinical areas of application are all anomalies of the CRP and SM levels.

Abstract: The invention relates to the use of at least folic acid or a folate and tetrahydrobiopterin (BH4) or derivatives thereof for treating or preventing cardiovascular or neurological disorders by modulation of the activity of nitric oxide synthase (NOS). The present invention also relates to the use of at least folio acid or a folate and tetrahydrobiopterin (BH4) or derivatives thereof for the production of a pharmaceutical preparation suitable for influencing the nitric oxide (NO) level, particularly by modulation of the activity of nitric oxide synthase (NOS) by reducing superoxide (O2.) production and enhancing nitric oxide (NO) synthesis. This effect occurs in absence of negative changes in other risk factors, e.g. lipids, blood pressure and homocysteine. Clinical areas of application include all anomalies of the nitric oxide level, particularly the prevention and treatment of cardiovascular and of neurological disorders.
