ABSTRACT:
Vitamin D.sub.3 derivatives of formula (I): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3, which may be the same or different, each represent a hydrogen atom or a hydroxyl group; R.sub.4 is hydrogen or a C.sub.4-6 alkyl group that is optionally substituted by a hydroxyl group; preferably 22-oxa-1,25-(OJ).sub.2 D.sub.3, or OCT, are administered to treat hyperparathyroidism, particularly secondary hyperparathyroidism, without inducing hypercalcemia. The derivatives may be administered orally or parenterally. They are preferably administered intravenously in the course of renal dialysis.
