Hydroxyl group on 21 st position on ring D for mineralocorticoid activity 5. Changes to modify pharmacokinetic properties The steroids can be made more lipid soluble or more water soluble by making suitable ester derivatives of hydroxyl OH groups. Derivatives with increased lipid solubility are often made to decrease the release rate of the drug from intramuscular IM injection sites i. More lipid-soluble derivatives also have improved skin absorption properties and thus, are preferred for dermatological preparations.
Contd… Since hydrolyzing enzymes are found throughout mammalian cells especially in the liver, converting OH groups to esters does not significantly modify the activity of most compounds. These inactivation processes limit the effectiveness of these hormones as orally available drugs. Although micronized forms of estradiol and progesterone are available for oral administration.
Lipophilicity can be increased by…. Absorption after oral administration is rapid. Maximum biological effect seen after h Distribution: Concentration of transcortin is increased by oestrogens eg pregnancy, oral contraceptives. In patients with very low serum albumin doses should be reduced due to reduced binding capacity 4.
