Sensipar is a drug manufactured by Amgen. Sensipar is the trade name, the generic name for this drug is “Cinacalcet”. Sensipar comes as a small pill in three strengths (30mg, 60mg, and 90mg). This drug was designed for the treatment of SECONDARY hyperparathyroidism.
What is the half-life of cinacalcet?
The terminal elimination half-life is 30-40 hours, and steady-state concentrations are achieved within 7 days. The pharmacokinetics of cinacalcet are dose proportional over the dose range of 30-180 mg. The pharmacokinetic profile of cinacalcet is not notably affected by varying degrees of renal impairment.How often is Sensipar taken?
Sensipar® is taken once a day in one of the 5 recommended daily doses. Sensipar® tablets should be taken whole. Do not crush or split the tablet.
Is cinacalcet a phosphate binder?
Phosphate Binders Cinacalcet is a type II calcimimetic agent that binds the trans-membrane region of the calcium-sensing receptor, resulting in allosteric modulation. The change in receptor configuration makes it more sensitive to serum calcium and results in a reduction of serum PTH at lower levels of serum calcium.
Does Sensipar Dialyze out?
No effect of renal function or dialysis on pharmacokinetics of cinacalcet (Sensipar/Mimpara)
What is the generic for sensipar?
Cinacalcet (Sensipar) is available as a generic medication and may be significantly cheaper compared to the brand version.Does sensipar lower calcium?
Sensipar can cause low calcium blood levels. Tell your doctor if you have symptoms of low calcium levels including numb or tingling skin, severe muscle spasms, seizures, unusual tiredness, or fast/irregular/pounding heartbeat.
Can you cut cinacalcet in half?Do not crush or break a cinacalcet tablet. Swallow the pill whole. To be sure your calcium and phosphorous levels do not get too low, your blood will need to be tested 1 week after you start taking cinacalcet or whenever your dose is changed. You may also need blood tests on a regular basis during treatment.
Article first time published onWhat is tertiary hyperparathyroidism?
Tertiary hyperparathyroidism is characterized by excessive secretion of PTH after longstanding secondary hyperparathyroidism, in which hypercalcemia has ensued. Tertiary hyperparathyroidism typically occurs in men and women with chronic kidney disease usually after kidney transplant.
What is Renvela 800 for?
Renvela (sevelamer) is a phosphate binder. Sevelamer helps prevent hypocalcemia (low levels of calcium in the body) caused by elevated phosphorus. Renvela is used to control phosphorus levels in people with chronic kidney disease who are on dialysis.
Does everyone have a parathyroid?
Everyone has four parathyroid glands, usually located right around the thyroid gland at the base of the neck. About 1 in 100 people (1 in 50 women over 50) will develop a parathyroid gland tumor during their lifetime, causing a disease called “hyperparathyroidism”.
Why is sensipar given to dialysis patients?
Indication Sensipar® (cinacalcet) is indicated for the treatment of secondary hyperparathyroidism (HPT) in adult patients with chronic kidney disease (CKD) on dialysis. Sensipar® should not be used in adult patients with CKD who are not on dialysis because of an increased risk of low calcium levels.
What is secondary hyperparathyroidism?
Secondary hyperparathyroidism occurs when the parathyroid glands become enlarged and release too much PTH, causing a high blood level of PTH. There are several reasons why this happens in patients with kidney disease: Higher blood phosphorus levels.
What is sensipar used to treat?
Cinacalcet is used to treat increased amounts of a certain hormone (parathyroid) in people with long-term kidney disease who are on dialysis. It is also used to treat increased amounts of calcium in people with an overactive parathyroid gland or in people with cancer of the parathyroid gland.
How do I change from Parsabiv to sensipar?
2.4 Switching from Parsabiv (etelcalcetide) to Sensipar Discontinue etelcalcetide for at least 4 weeks prior to starting Sensipar. Ensure corrected serum calcium is at or above the lower limit of normal prior to Sensipar initiation [see Warnings and Precautions (5.1)].
How does cinacalcet decrease phosphorus?
The decrease in serum P with cinacalcet therapy is likely due to decreased release of P from bone and/or decreased intestinal absorption of P.
What are Calcimimetic drugs?
Calcimimetics are a group of drugs that are allosteric activators of the calcium-sensing receptor, thereby enhancing signaling and decreasing PTH release independent of vitamin D.
How much calcitriol should I take?
The recommended initial dosage of calcitriol is 0.25 mcg/day in adults and pediatric patients 3 years of age and older. This dosage may be increased if necessary to 0.5 mcg/day. For pediatric patients less than 3 years of age, the recommended initial dosage of calcitriol is 10 to 15 ng/kg/day.
What is cinacalcet used to treat?
Cinacalcet is used to treat hyperparathyroidism in patients with chronic kidney disease who are on dialysis. Hyperparathyroidism is a condition that is caused when the parathyroid glands located in the neck make too much parathyroid hormone (PTH).
What is the normal level of calcium in blood how is it maintained?
In our bodies, calcium is a mineral that makes up our bones, as well as a salt that dissolves in our blood and regulates bodily function. At UCLA, the normal range for blood calcium level is 8.6 to 10.3 mg/dL. In order to maintain a normal calcium level, the body uses hormones to regulate blood calcium levels.
Does sensipar lower blood pressure?
Low blood pressure: Blood pressure may occasionally drop when taking cinacalcet. Be alert for any lightheadedness, dizziness, or a faster-than-normal heart rate.
Does sensipar cause weight gain?
Sensipar side effects muscle pain, tightness, or contraction; a seizure (convulsions); shortness of breath (even with mild exertion), swelling, rapid weight gain; signs of stomach bleeding – bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds; or.
When is the best time to take cinacalcet?
It is usually taken once a day with food or shortly after a meal. To help you remember to take cinacalcet, take it at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand.

What drug company makes sensipar?
Amgen provides several resources to help your patients take Sensipar® as prescribed.
Is cinacalcet the same as calcitriol?
Conclusions: We conclude that combination therapy of low-dose cinacalcet and calcitriol is more effective than calcitriol alone as a treatment for moderate and severe UHPT in chronic dialysis patients. Furthermore, this therapy is associated with improvement in hyperphosphatemia and hypercalcemia.
What are side effects of calcitriol?
- dehydration symptoms–feeling very thirsty or hot, being unable to urinate, heavy sweating, or hot and dry skin;
- high calcium levels–nausea, vomiting, constipation, increased thirst or urination, muscle weakness, bone pain, confusion, lack of energy, or tired feeling; or.
Can you crush calcitriol?
Do not take it on an empty stomach. This will make it easier for your body to absorb the medication. Do not crush, chew, or break the tablets. Swallow them whole.
What is the difference between primary hyperparathyroidism and secondary hyperparathyroidism?
Parathyroid glands can go crazy all on their own (called primary hyperparathyroidism) or when some other disease forces them to go crazy (called secondary hyperparathyroidism). Secondary hyperparathyroidism is a disease of the parathyroid glands that was caused by some other disease.
