Problems solved by technology

There is a risk of infection in multiple administrations, poor patient compliance, and often forgetting to administer
Storage and transportation at 2-8°C, and pre-filled injection pens are difficult to use, high in cost, and expensive;
[0008] 2) Preparation of microspheres can reduce the frequency of administration and the risk of infection, but its production cost is high, the price is expensive, and the therapeutic properties of teriparatide are not suitable for preparation into sustained-release preparations

Abstract

The invention discloses a teriparatide freeze-dried pharmaceutical composition and a preparation method thereof, and the teriparatide freeze-dried pharmaceutical composition comprises the following raw materials in parts by weight: 0.2 part of teriparatide, 50-150 parts of mannitol, 5-50 parts of lactose, 0.1-1 part of menthol, 0.1-0.5 part of sodium acetate, 0.1-0.5 part of glacial acetic acid, and a proper amount of a pH regulator for regulating the pH value to 3.0-6.0. The administration mode of the teriparatide freeze-dried pharmaceutical composition is sublingual administration, the formula of the teriparatide freeze-dried pharmaceutical composition provided by the invention does not contain a bacteriostatic agent, so that the toxicity to a human body is less, in addition, the administration mode of the teriparatide freeze-dried pharmaceutical composition is sublingual administration, injection administration is not needed, and the application range is wide. The pricking feeling caused by administration is reduced, the sterile risk in clinical use is reduced, and the compliance of a patient is improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, and relates to a teriparatide freeze-dried pharmaceutical composition and a preparation method thereof. Background technique [0002] Teriparatide (Teriparatide) is the first new bone-forming drug approved by the US Food and Drug Administration (FDA). It is suitable for the treatment of osteoporosis in postmenopausal women with a high risk of fracture. and nonvertebral fracture risk. Teriparatide is an endogenous parathyroid hormone containing 34 amino acids. It has a 1-34 amino acid fragment in the N-terminal region with biological activity. Its molecular formula is C181H291N55O51S2, its molecular weight is 4177.77, and it has good water solubility. Teriparatide injection was approved for marketing by FDA in November 2002, followed by EMEA in June 2003, and PMDA in July 2010. In March 2011, Teriparatide Injection was approved to enter the Chinese drug market, and was approved by the ...
