Frequency of administration of growth hormone--an important factor in determining growth response to exogenous growth hormone.
Growth hormone (GH) secretion in man occurs in a pulsatile manner with a dominant periodicity of 200 min. Animal studies and growth hormone-releasing hormone therapeutic studies in man demonstrate the importance of the frequency of GH pulses on the growth response observed. Daily injections of GH produce effective growth. More frequent regimens may be beneficial to prevent waining of the growth spurt induced by GH therapy.
