Aminopentamide is a potent antispasmodic agent. As a cholinergic blocking agent for smooth muscle, its action is similar to atropine. Aminopentamide hydrogen sulfate is marketed under the brand name Centrine indicated in the treatment of acute abdominal visceral spasm, pylorospasm or hypertrophic gastritis and associated nausea, vomiting and/or diarrhea of the dogs and cats. Centrine effectively reduces the tone and amplitude of colonic contractions to a greater degree and for a more extended period than does atropine. Centrine effects a reduction in gastric secretion, a decrease in gastric acidity and a marked decrease in gastric motility. Aminopentamide is a nonselective muscarinic cholinergic .

Tricyclamol is a quaternary ammonium compound, which is a crystalline odorless substance, readily soluble in water. It may be given by mouth or by subcutaneous injection. Tricyclamol was used for its spasmolytic action on smooth muscle. In animals it inhibits the spasmogenic effects of acetylcholine (ACh), carbachol, pilocarpine and barium chloride. In relaxing ACh-induced spasm of isolated rabbit ileum the activities of the dextro and laevo isomers of tricyclamol were approximately 0.006 and 2 times that of atropine sulphate respectively. Further, in inhibiting the stretch reflex of isolated guinea-pig ileum the laevo isomer was much more active than the dextro and about twice as potent as the racemate. Tricyclamol blocks the superior cervical ganglion. Tricyclamol chloride has a marked effect in reducing the motility of the stomach and duodenum, and to a far greater extent than the results produced by hyoscyamine. This action may be of value in controlling the pain of peptic ulceration, since it is likely that the pain, at least in part, is due to spasm.

Tolonium chloride (INN, also known as toluidine blue or TBO) is a phenothiazine that has been used as a hemostatic, a biological stain, and a dye for wool and silk. Tolonium chloride has also been used as a diagnostic aid for oral and gastric neoplasms and in the identification of the parathyroid gland in thyroid surgery. Toluidine blue has high affinity for acidic tissue components, thereby staining tissues rich in DNA and RNA. It has found wide applications both as vital staining in living tissues and as a special stain owing to its metachromatic property. Toluidine blue has been used in vivo to identify dysplasia and carcinoma of the oral cavity.

Bithionol is a synthetic sulfanediyl-bis-dichlorphenol), potent photosensitizer with the potential to cause serious skin disorders, formerly marketed as an active ingredient in various topical drug products. Bithionol has antibacterial and anthelmintic properties along with algaecide activity. Bithionol has been shown to be a potent inhibitor of soluble adenylyl cyclase (sAC, Adenylate cyclase type 10 ), an intracellular enzyme important in the catalysis of ATP to cAMP. Bithionol is the first known sAC inhibitor to act through the bicarbonate binding site via a mostly allosteric mechanism. Bithionol is used for treatment of tapeworm infections of dogs, cats, and poultry and for tapeworm and rumen fluke infections of sheep, horses, cattle, and goats.

STANOLONE, also known as dihydrotestosterone, is a potent androgenic metabolite of testosterone and anabolic agent for systemic use. It may be used as a replacement of male sex steroids in men who have androgen deficiency, for example as a result of the loss of both testes, and also the treatment of certain rare forms of aplastic anemia which are or may be responsive to anabolic androgens.

Diphenylpyraline is an antihistamine that prevents but does not reverse, responses mediated by histamine alone. Diphenylpyraline antagonizes most of the pharmacological effects of histamine, including urticaria and pruritus. Also, diphenylpyraline may exhibit anticholinergic actions (as do most of the antihistamines) and may thus provide a drying effect on the nasal mucosa. Antihistamines such as diphenylpyraline used in the treatment of allergy act by competing with histamine for H1-receptor sites on effector cells. This reduces the effects of histamine, leading to a temporary reduction of allergy symptoms.

Propantheline is an antimuscarinic agent used for the treatment of excessive sweating (hyperhidrosis), cramps or spasms of the stomach, intestines (gut) or bladder, and involuntary urination (enuresis). It can also be used to control the symptoms of irritable bowel syndrome and similar conditions. Propantheline is one of a group of antispasmodic medications which work by blocking the action of the chemical messenger acetylcholine, which is produced by nerve cells, to muscarinic receptors present in various smooth muscular tissues, in places such as the gut, bladder, and eye. Normally, the binding of acetylcholine induces involuntary smooth muscular contractions. Varying degrees of drying of salivary secretions may occur as well as decreased sweating. Ophthalmic side effects include blurred vision, mydriasis, cycloplegia, and increased ocular tension. Other reported adverse reactions include urinary hesitancy and retention, tachycardia, palpitations, loss of the sense of taste, headache, nervousness, mental confusion, drowsiness, weakness, dizziness, insomnia, nausea, vomiting, constipation, bloated feeling, impotence, suppression of lactation, and allergic reactions or drug idiosyncrasies including anaphylaxis, urticaria and other dermal manifestations.

Merethoxylline is a mercurial diuretic. As an equimolar mixture of merethoxylline procaine and theophylline in the molecular proportion 1:1.4 (DICURIN PROCAINE, Lilly) has been used in the treatment of oedema and ascites. The procaine component helps in reducing the discomfort of local irritation caused by mercurial compound when injected into tissues.
