Trimethadione (brand name is TRIDIONE) is an oxazolidinedione compound that was developed as an antiepileptic agent for control of petit mal seizures that are refractory to treatment with other drugs. Tridione does not modify the maximal seizure pattern in patients undergoing electroconvulsive therapy and has a sedative effect that may increase to the point of ataxia when excessive doses are used. Trimethadione acts as a voltage-activated T-type Ca2+ channel blocker. Trimethadione is rapidly absorbed from the gastrointestinal tract. It is demethylated by liver microsomes to the active metabolite, dimethadione. Approximately 3% of a daily dose of tridione is recovered in the urine as the unchanged drug. The majority of trimethadione is excreted slowly by the kidney in the form of dimethadione.

Sulfabenzamide is an antibacterial/antimicrobial. Often used in conjunction with sulfathiazole and sulfacetamide (trade name - Sultrin) as a topical, intravaginal antibacterial preparation against Haemophilus (Gardnerella) vaginalis bacteria. The mode of action of SULTRIN is not completely known. Indirect effects, such as lowering the vaginal pH, may be equally important mechanisms.
Tubocurarine, a naturally occurring alkaloid, is used to treat smoking withdrawl syndrom. Tubocurarine, the chief alkaloid in tobacco products, binds stereo-selectively to nicotinic-cholinergic receptors at the autonomic ganglia, in the adrenal medulla, at neuromuscular junctions, and in the brain. Two types of central nervous system effects are believed to be the basis of Tubocurarine's positively reinforcing properties. A stimulating effect is exerted mainly in the cortex via the locus ceruleus and a reward effect is exerted in the limbic system. At low doses the stimulant effects predominate while at high doses the reward effects predominate. Intermittent intravenous administration of Tubocurarine activates neurohormonal pathways, releasing acetylcholine, norepinephrine, dopamine, serotonin, vasopressin, beta-endorphin, growth hormone, and ACTH. Tubocurarine competes with acetylcholine for post-synaptic nicotinic NM receptors and blocks them.
Nitrofurazone is used to treat burns that have become infected. It is also used to treat skin infections due to skin grafts. It works by killing bacteria or preventing their growth. The exact mechanism of action is unknown. Nitrofurazone inhibits several bacterial enzymes, especially those involved in the aerobic and anaerobic degradation of glucose and pyruvate. The severe or irreversible adverse effects of Nitrofurazone, which give rise to further complications include Peripheral neuropathy, Thromboembolic disorder.

TRICHOLINE CITRATE is indicated for the treatment and management of hepatic disorders and asthma symptoms in adults. It exerts lipotropic action in the hepatic cells. It also can lower the symptoms of asthma and reducing the pro-inflammatory and inflammatory mediators of the leukotriene pathway.

Aminohippurate (p-aminohippuric acid, PAH, PAHA) is the glycine amide of p-aminobenzoic acid. Aminohippuric acid sodium salt is an agent to measure effective renal plasma flow (ERPF).
Dicumarol is an coumarin-like compound found in sweet clover. It is used as oral anticoagulant and acts by inhibiting the hepatic synthesis of vitamin K-dependent coagulation factors (prothrombin and factors VII, IX, and X). It results in decresed prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots. Dicumarol is also used in biochemical experiments as an inhibitor of reductases.

Salicylamide is a non-prescription drug with analgesic and antipyretic properties (NSAID). It is used in combination with aspirin and caffeine in the over-the-counter pain remedies (such as EXAPRIN). Salicylamide can produce sedation and sleep in humans and animals. Has been used as model drug in pharmacokinetic and metabolic studies as a dophamine 2 receptor ligand. Salicylamide is a white or light pink crystals or powder. Organic compound it is a carboxamide derivative of salicylic acid.

Sulfamerazine is a sulfonamide antibiotic, which acts by inhibiting folic acid synthesis in bacterias. The primary target of sulfamerazine is believed to be dihydropteroate synthetase. Sulfamerazine (in comination with Sulfadiazine and Sulfamethazine) was used in the US under different names, including the earliest brand of Neotrizine. Nowdays, the drugs containing sulfamerazine are no longer available for use in humans in the US, however, they may be prescribed for veterinary purposes.
