  • Title: The effect of L-DOPA administration on thyrotropin (TSH) and thyrotropin releasing hormone (TRH) levels in serum in primary or pituitary hypothyroidism.
    Author: Mitsuma T, Hirooka Y, Wanibe S, Nihei N.
    Journal: Endocrinol Jpn; 1978 Oct; 25(5):499-501. PubMed ID: 105899.
    Abstract:
    The effect of acute administration of L-DOPA on TSH and TRH levels in serum was studied in primary or pituitary hypothyroidism. TRH levels in serum fell and then returned to initial levels after L-DOPA administration in primary or pituitary hypothyroidism. TSH levels in serum fell and then returned to initial levels after L-DOPA administration in primary hypothyroidism. T4 and T3 levels in serum did not change after L-DOPA administration in primary or pituitary hypothyroidism. These data suggested that L-DOPA might act directly to hypothalamus.
