A pharmaceutical composition for oral administration comprising PTH, wherein the in vitro release of PTH-when tested in a dissolution test of pharmacopoeia standard-is delayed with at least 2 hours and once the release starts, at least 90% w/w such as, e.g., at least 95% or at least 99% of all PTH contained in the composition is released within at the most 2 hours. The composition may also comprises a calcium containing compound and/or a vitamin, D. In particular, PTH is administered in combination with a calcium-containing compound for the treatment or prevention of bone-related diseases, so that I) an effective amount of a calcium-containing compound is administered to lower the plasma level of endogenous PTH, and II) an effective amount of PTH is administered to obtain a peak concentration of Pm once the endogeneous PTH level is lowered. This present a potential therapeutic or prophylactic regimen for bone-related disorders including osteoporosis.

What is described is a method of delivering PTH to a human, comprising exposing a layer of mucosal cells to a mixture of PTH and an enhancer, wherein the enhancer is capable of modulating the barrier function of a cellular tight junction. Specifically, the method of delivering PTH to a human by intranasal administration comprises use of an aqueous solution of growth and excipients in a bottle and a droplet-generating actuator attached to the bottle and fluidly connected to the PTH solution in the container, wherein the actuator produces a spray of the PTH solution through a tip of the actuator when the actuator is engaged, wherein the spray of PTH solution has a spray pattern ellipticity ratio of from about 1.0 to about 1.4 when measured at a height of 3.0 cm from the actuator tip.

The invention provides the method of merged protein which contains recombined human parathormone, coding the merged protein's DNA sequence, the carrier which contains the DNA sequence, the host cell which contains the carrier, using genetic engineering to prepare the merged protein and then produce PTH1-34. Enzyme cutting the merged protein by enterokinase can produce the recombined human parathormone PTH (1-34) has high physiologically active.

The present invention relates to novel methods and devices for differentiating in a patient parathyroid diseases, such as hyperparathyroidism and related bone diseases, from normal or non-disease states. One detects whole or non-fragmented (1 to 84) parathyroid hormone in a biological sample and also a large non-whole parathyroid hormone peptide fragment that can function as a parathyroid hormone antagonist. By either comparing values or using independently the value of either the large non-whole parathyroid hormone peptide fragment, the whole parathyroid hormone, or the combination of these values one is able to differentiate parathyroid and bone related disease states, as well as differentiate such states from normal states.
