Troglitazone (TGZ, brand name: Rezulin and Prelay) is a peroxisome proliferator-activated receptor gamma (PPAR gamma) ligand, which was developed by Daiichi Sankyo and approved for the US market for the treatment of Type II diabetes mellitus. The drug is used alone or in combination with a sulfonylurea, metformin, or insulin as an adjunct to diet and exercise, and was not indicated as initial therapy in patients with type 2 diabetes. This drug was withdrawn from the UK market due to liver toxicity. It was removed from the US market in 2000, only 3 years after its introduction and from Japan, shortly afterward. In addition, was conducted a clinical trial for the treatment of patients with advanced liposarcoma by using troglitazone, but the positive result wasn’t obtained. It was shown, that in case of cancer cells troglitazone acted independently of PPAR gamma, by up-regulation of early growth response-1 (Egr-1). Egr-1 transcription factor has been linked to apoptosis and shown to be activated by extracellular signal-regulated kinase (ERK).

Mivacurium chloride (Mivacron) is a new benzylisoquinolinium choline-like diester neuromuscular blocking drug with an onset of action at equipotent doses that is comparable to atracurium and vecuronium but slower than succinylcholine. MIVACRON (a mixture of three stereoisomers) binds competitively to cholinergic receptors on the motor end-plate to antagonize the action of acetylcholine, resulting in a block of neuromuscular transmission. This action is antagonized by acetylcholinesterase inhibitors, such as neostigmine. MIVACRON is a short-acting neuromuscular blocking agent indicated for inpatients and outpatients, as an adjunct to general anesthesia, to facilitate tracheal intubation and to provide skeletal muscle relaxation during surgery or mechanical ventilation.

Doxacurium chloride (formerly recognized as BW938U80 or BW A938U) is a neuromuscular-blocking drug or skeletal muscle relaxant in the category of non-depolarizing neuromuscular-blocking drugs, used adjunctively in anesthesia for endotracheal intubation or to facilitate mechanical ventilation. Unlike a number of other related skeletal muscle relaxants, it is rarely used adjunctively to facilitate endotracheal intubation. Doxacurium chloride is a mixture of three trans, trans stereoisomers, a dl pair [(1R,1'R ,2S,2'S ) and (1S,1'S ,2R,2'R )] and a meso form (1R,1'S,2S,2'R). NUROMAX binds competitively to cholinergic receptors on the motor end-plate to antagonize the action of acetylcholine, resulting in a block of neuromuscular transmission. This action is antagonized by acetylcholinesterase inhibitors, such as neostigmine.
