Question: Turbidimetric inhibition immunoassay is used in many commercial immunoassays, including this medication sold under which brand name?

Context paragraphs:
Simcere Pharmaceutical: Simcere Pharmaceutical Group or Simcere Pharmaceutical () is a manufacturer and supplier of branded generic pharmaceuticals in the Chinese market.  Its focus is to introduce generic and pharmaceutical products for the treatment of diseases with high incidence and/or mortality rate.  The Company has introduced a generic anti-stroke medication under the brand name, "Bicun", and an anti-cancer medication under the brand name, "Endu".  Its products include antibiotics, anti-stroke medications, anti-inflammatory drugs, anti-cancer medications and other medicines.  In addition, it has obtained approvals from the China State Food and Drug Administration (SFDA) to manufacture and sell over 210 other products.

Alsactide: Alsactide (INN) (brand name Synchrodyn 1-17 or simply Synchrodyn, former development code name Hoechst 433), also known as alisactide, is a synthetic peptide and analogue of adrenocorticotropic hormone (ACTH) which is used in Italy as a diagnostic agent in kidney function for adrenal insufficiency.  Like ACTH, alsactide is thought to act as a non-selective agonist of the melanocortin receptors, including the ACTH receptor (MCR).  However, it appears to show a different profile of receptor selectivity relative to ACTH, as it apparently demonstrated no evidence of inhibition of endogenous ACTH in Addison's disease patients.

Turbidimetric inhibition immunoassay: Turbidimetric inhibition immuno assay (TINIA) is a type of immunoassay that uses turbidimetry as the measurement principle and is used for many commercial immunoassays, e.g. measurement of HbA1c%, Digoxin etc. in whole blood sample in several commercial assays employ this principle.

Digoxin: Digoxin, sold under the brand name Lanoxin among others, is a medication used to treat various heart conditions.  Most frequently it is used for atrial fibrillation, atrial flutter, and heart failure.  Digoxin is taken by mouth or by injection into a vein.

Difenamizole: Difenamizole (INN) (brand name Pasalin; former developmental code name AP-14) is a nonsteroidal anti-inflammatory drug (NSAID) and analgesic of the pyrazolone group related to metamizole.  It has monoaminergic properties, including inhibition of monoamine oxidase, augmentation of pargyline-induced elevation of striatal dopamine levels, inhibition of K-induced striatal dopamine release, and inhibition of the reuptake of dopamine.

Eletriptan: Eletriptan (trade name Relpax, used in the form of eletriptan hydrobromide) is a second generation triptan drug intended for treatment of migraine headaches.  It is used as an abortive medication, blocking a migraine attack which is already in progress.  Eletriptan is marketed and manufactured by Pfizer Inc.  It is sold in the US and Canada under the brand name Relpax, and in several other countries under the brand name Relert.

Safinamide: Safinamide (INN; brand name Xadago) is a drug used as an add-on treatment for Parkinson's disease during "off" episodes; it has multiple modes of action, including the inhibition of monoamine oxidase B.

Rivaroxaban: Rivaroxaban, sold under the brand name Xarelto, among others, is an anticoagulant medication (blood thinner), which is taken by mouth.  It is commonly used to prevent blood clots.  It was initially developed by Bayer.  In the United States, it is marketed by Janssen Pharmaceutica.  It is the first available active direct factor Xa inhibitor which is taken by mouth.  The maximum inhibition of factor Xa occurs four hours after a dose.  The effects last approximately 8–12 hours, but factor Xa activity does not return to normal within 24 hours, so once-daily dosing is possible.

Liothyronine: Liothyronine is a synthetic form of triiodothyronine (T3), a thyroid hormone used to treat hypothyroidism and myxedema coma.  T3 is the metabolically active thyroid hormone, which causes feedback inhibition, and lowers elevated TSH levels.  It increases metabolism in peripheral tissues and is indicated when there is an impaired conversion of T4 to T3 in peripheral tissues.  It is also used as an augmentation strategy in treating major depressive disorder when used in combination with antidepressants.  It is marketed as the sodium salt under the brand name Cytomel (or Tertroxin in Australia).

Delmadinone acetate: Delmadinone acetate (abbreviated as DMA), sold under the brand name Tardak, is a progestin and antiandrogen which is used in veterinary medicine to treat androgen-dependent conditions such as benign prostatic hyperplasia.  It must be used with care as it has the potential to cause adrenal insufficiency via inhibition of adrenocorticotropic hormone (ACTH) secretion from the pituitary gland.  DMA is the C17α acetate ester of delmadinone, which, in contrast to DMA, was never marketed for medical use.
