Effect on lipoproteins of Trisequens, a combined hormone preparation.

Lipoprotein concentrations were measured in 31 post-menopausal women during 1 yr of treatment with Trisequens, a natural oestrogen-progestogen preparation. Serum triglyceride, high density lipoprotein and very low density lipoprotein cholesterol concentrations did not change significantly, but low density lipoprotein cholesterol concentrations fell over the first 6 mth. After 1 yr none of the lipoprotein fractions differed significantly in concentration from pre-treatment levels.
