Taurocholic acid is a bile acid and is the product of conjugation of cholic acid with taurine. Its sodium salt is the chief ingredient of the bile of carnivorous animals. Taurocholic acid, as with all bile acids, acts as a detergent to solubilize fats for absorption and is itself absorbed. It is used as a cholagogue and cholerectic (a bile purging agent). Hydrolysis of taurocholic acid yields taurine, a nonessential amino acid. Taurocholic acid is one of the main components of urinary nonsulfated bile acids in biliary atresia. Raised levels of the bile acid taurocholate in the fetal serum in obstetric cholestasis may result in the development of a fetal dysrhythmia and in sudden intra-uterine death. In medical use, it is administered as a cholagogue and choleretic. Taurocholic acid is a potent TGR5 ligand, and in dogs, colonic perfusion with TCA induces PYY secretion. TCA enemas could stimulate GLP-1 and PYY secretion in obese patients with type 2 diabetes receiving the dipeptidyl peptidase-4 (DPP-4) inhibitor, sitagliptin. Satiogen Pharmaceuticals is developing rectally administered taurocholic acid, a bile acid, for the treatment of obesity and type 2 diabetes mellitus.

Rebamipide, an amino acid derivative of 2-(1H)-quinolinone, is used for mucosal protection, healing of gastroduodenal ulcers, and treatment of gastritis. It works by enhancing mucosal defense, scavenging free radicals, and temporarily activating genes encoding cyclooxygenase-2. Rebamipide is used in a number of Asian countries including Japan (marketed as Mucosta), South Korea, China, and India (where it is marketed under the trade name Rebagen). It is not approved by the Food and Drug Administration for use in the United States. Studies have shown that rebamipide can fight the damaging effects of NSAIDs on the GIT mucosa.

Trimebutine [3,4,5-trimethoxybenzoic acid 2-(dimethylamino)-2-phenylbutylester] is a noncompetitive spasmolytic agent. The actions of trimebutine on the gastrointestinal tract are mediated via (i) an agonist effect on peripheral mu, kappa and delta opiate receptors and (ii) release of gastrointestinal peptides such as motilin and modulation of the release of other peptides, including vasoactive intestinal peptide, gastrin and glucagon. Trimebutine attenuated colonic motility mainly through the inhibition of L-type Ca(2+) channels at higher concentrations, whereas, at lower concentrations, it depolarized membrane potentials by reducing BK(ca) currents, resulting in the enhancement of the muscle contractions.Trimebutine accelerates gastric emptying, induces premature phase III of the migrating motor complex in the intestine and modulates the contractile activity of the colon. It is indicated for the treatment and relief of symptoms associated with the irritable bowel syndrome (spastic colon); and in postoperative paralytic ileus in order to accelerate the resumption of the intestinal transit following abdominal surgery.

Atosiban (brand name Tractocile) is a competitive antagonist of human oxytocin at receptor level. In rats and guinea pigs, atosiban was shown to bind to oxytocin receptors, to decrease the frequency of contractions and the tone of the uterine musculature, resulting in a suppression of uterine contractions. Atosiban was also shown to bind to the vasopressin receptor, thus inhibiting the effect of vasopressin. Tractocile is indicated to delay imminent pre-term birth in pregnant adult women with: − regular uterine contractions of at least 30 seconds duration at a rate of ≥ 4 per 30 minutes − a cervical dilation of 1 to 3 cm (0-3 for nulliparas) and effacement of ≥ 50% − a gestational age from 24 until 33 completed weeks − a normal foetal heart rate. Atosiban does not have U.S. Food and Drug Administration (FDA) approval for use in the United States.

Tebipenem pivoxil is an oral carbapenem prodrug that was originated by Wyeth (now Pfizer). It was approved by Pharmaceuticals and Medical Devices Agency of Japan (PMDA) on Apr 22, 2009. It was developed and marketed as Orapenem® by Meiji Seika in Japan. Tebipenem pivoxil is a broad-spectrum orally-administered antibiotic, from the carbapenem subgroup of β-lactam antibiotics. Carbapenems are a class of beta-lactam antibiotics, which act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. It is used to treat otorhinolaryngological infection, otitis media and bacterial pneumonia. Orapenem® is available as granules for oral use, containing 100 mg Tebipenem pivoxil/g granules. According to the weight of children, 4 mg/kg, and twice a day after dinner.

Dibrompropamidine isetionate is an antiseptic. Ointment containing dibrompropamidine isetionate is used to treat minor eye or eyelid infections, such as conjunctivitis and blepharitis.

Dihomo-gamma-linolenic acid (DGLA) is an n-6 polyunsaturated fatty acid that is mainly metabolized to an anti-inflammatory eicosanoid, prostaglandin (PG) E1, via the cyclooxygenase (COX) pathway. DGLA exists widely in the human body and daily animal-source foods. Concentrations of DGLA in the serum of atopic dermatitis patients are lower than those in healthy volunteers. DGLA suppressed clinical severity of skin lesions dose-dependently, with an increase in DGLA contents in phospholipids of skin, spleen, and plasma. Discontinuation of DGLA administration resulted in the onset of dermatitis and a decrease in DGLA contents in skin, spleen, and plasma. These findings indicate that oral administration of DGLA effectively prevents the development of atopic dermatitis in NC/Nga mice. DGLA may have an anti-atherosclerotic effect in apoE-deficient mice via PGE1 formation. As dihomo-γ-linolenic acid and arachidonic acid compete for processing by these oxidation enzymes, introduction of dihomo-γ-linolenic acid to platelets is correlated to suppression of arachidonic acid metabolites and promotion of dihomo-γ-linolenic acid metabolites such as PGE1, which produces an antithrombotic effect.

Carnidazole (trade name Spartrix) is an antiprotozoal drug of the nitroimidazole class used in veterinary medicine. Spartrix (Carnidazole) is indicated for oral treatment of trichomoniasis (canker) in ornamental and homing (non-food) pigeons.
