Teriparatide SC Injection is a parathyroid hormone analog, (PTH 1-34), indicated for:

Increase of bone mass in men with primary or hypogonadal osteoporosis at high risk for fracture.
Treatment of men and women with osteoporosis associated with sustained systemic glucocorticoid therapy at high risk for fracture.

Teripen 20 mcg/80 mcl | PHARMACOLOGY

Endogenous 84-amino acid parathyroid hormone (PTH) is the primary regulator of calcium and phosphate metabolism in bone and kidney. Physiological actions of PTH include regulation of bone metabolism, renal tubular reabsorption of calcium and phosphate, and intestinal calcium absorption. The biological actions of PTH and teriparatide are mediated through binding to specific high-affinity cell-surface receptors. Teriparatide and the 34 N-terminal amino acids of PTH bind to these receptors with the same affinity and have the same physiological actions on bone and kidney. Teriparatide is not expected to accumulate in bone or other tissues. The skeletal effects of teriparatide depend upon the pattern of systemic exposure. Once-daily administration of teriparatide stimulates new bone formation on trabecular and cortical (periosteal and/or endosteal) bone surfaces by preferential stimulation of osteoblastic activity over osteoclastic activity. In monkey studies, teriparatide improved trabecular microarchitecture and increased bone mass and strength by stimulating new bone formation in both cancellous and cortical bone. In humans, the anabolic effects of teriparatide manifest as an increase in skeletal mass, an increase in markers of bone formation and resorption, and an increase in bone strength. By contrast, continuous excess of endogenous PTH, as occurs in hyperparathyroidism, may be detrimental to the skeleton because bone resorption may be stimulated more than bone formation.

Teripen 20 mcg/80 mcl | DOSAGE

Treatment of Postmenopausal Women with Osteoporosis at High Risk for Fracture: The recommended dose is 20 mcg subcutaneously once a day.Increase of Bone Mass in Men with Primary or Hypogonadal Osteoporosis at High Risk for Fracture: The recommended dose is 20 mcg subcutaneously once a day.Treatment of Men and Women with Glucocorticoid-Induced Osteoporosis at High Risk for Fracture: The recommended dose is 20 mcg subcutaneously once a day.Pediatric Use: The safety and efficacy of Teriparatide have not been established in any pediatric population.Hepatic Impairment: No studies have been performed in patients with hepatic impairment.

Teripen 20 mcg/80 mcl | DRUG INTERACTIONS

Digoxin: A single Teriparatide dose did not alter the effect of digoxin on the systolic time interval (from electrocardiographic Q-wave onset to aortic valve closure, a measure of digoxin’s calcium-mediated cardiac effect). However, because Teriparatide may transiently increase serum calcium, Teriparatide should be used with caution in patients taking digoxinHydrochlorothiazide: The coadministration of hydrochlorothiazide 25 mg with teriparatide did not affect the serum calcium response to teriparatide 40 mcg. The effect of coadministration of a higher dose of hydrochlorothiazide with teriparatide on serum calcium levels has not been studied Furosemide: Coadministration of intravenous furosemide (20 to 100 mg) with teriparatide 40 mcg in healthy people and patients with mild, moderate, or severe renal impairment (CrCl 13 to 72 mL/min) resulted in small increases in the serum calcium (2%) and 24-hour urine calcium (37%) responses to teriparatide that did not appear to be clinically important

Teripen 20 mcg/80 mcl | SIDE EFFECTS

Most common adverse reactions include: arthralgia, pain, and nausea.

Teripen 20 mcg/80 mcl | USE DURING PREGNANCY AND LACTATION

There are no available data on Teriparatide use in pregnant women to evaluate for drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Consider discontinuing Teriparatide when pregnancy is recognized. It is not known whether teriparatide is excreted in human milk, affects human milk production, or has effects on the breastfed infant.
