CHLORDANTOIN, an imidazolidine-2,4-dione derivative, is a topical antifungal agent with activity against Candida albicans. It is used for the treatment of vaginal candidiasis.

Rotoxamine ((S)-carbinoxamine) is maleic acid salt of the levorotatory isomer of Carbinoxamine (a first-generation antihistamine of the ethanolamine class). Ethanolamine antihistamines have significant antimuscarinic activity and produce marked sedation in most patients. In addition to the usual allergic symptoms, the drug also treats an irritant cough and nausea, vomiting, and vertigo associated with motion sickness. It also is used commonly to treat drug-induced extrapyramidal symptoms as well as to treat mild cases of Parkinson's disease. Rotoxamine is used to treat runny or stuffy nose, sneezing, itching, watery eyes, hives, skin rash, itching, and other symptoms of allergies and the common cold.

Methdilazine is a phenothiazine compound with antihistaminic activity. Methdilazine binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine. It is used for the symptomatic relief of hypersensitivity reactions and particularly for the control of pruritic skin disorders.

Propiomazine is a typical antipsychotic, blocking H1 receptors and is primarily indicated in conditions Insomnia. Propiomazine was also used under brand name largon for the relief of restlessness and apprehension, preoperatively or during surgery. In addition largon was used as an adjunct to analgesics for the relief of restlessness and apprehension during labor. But this drug was discontinued.

Oxymetholone (17beta-hydroxy-2-[hydroxymethylene]-17-methyl-5alpha-androstan-3-one) is a 17alpha-alkylated anabolic-androgenic steroid and a synthetic derivative of testosterone. It has been approved by the US Food and Drug Administration for the treatment of anemias caused by deficient red cell production. Acquired aplastic anemia, congenital aplastic anemia, myelofibrosis and the hypoplastic anemias due to the administration of myelotoxic drugs often respond. Drug interactions exist with cimetidine, paroxetine, and haloperidol, but are not expected with indinavir, ritonavir, clarithromycin, or itraconazole.

EMYLCAMATE (STRIATRAN®), the carbamate ester of the tertiary alcohol methylpentanol, is a tranquilizing and muscle relaxant agent used for the treatment of anxiety and tension.

PROTHIPENDYL is a neuroleptic azaphenothiazine used to treat anxiety and agitation in psychotic syndromes. It also shows strong antihistamine and anti-emetic actions.

Methyclothiazide, a diuretic-antihypertensive agent, is a member of the benzothiadiazine (thiazide) class of drugs. Methyclothiazide has a per mg natriuretic activity approximately 100 times that of the prototype thiazide, chlorothiazide. At maximal therapeutic dosages, all thiazides are approximately equal in their diuretic/natriuretic effects. Like other benzothiadiazines, methyclothiazide also has antihypertensive properties, and may be used for this purpose either alone or to enhance the antihypertensive action of other drugs. Methyclothiazide appears to block the active reabsorption of chloride and possibly sodium in the ascending loop of Henle, altering electrolyte transfer in the proximal tubule. This results in excretion of sodium, chloride, and water and, hence, diuresis. As a diuretic, methyclothiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like methyclothiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of methyclothiazide is less well understood although it may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle. Methyclothiazide is used in the management of hypertension either as the sole therapeutic agent or to enhance the effect of other antihypertensive drugs in the more severe forms of hypertension. Also used as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy.

Benzthiazide (trade names Aquatag, Dihydrex, Diucen, Edemax, Exna, Foven and others) is a thiazide diuretic used in the treatment of high blood pressure and edema. It is no longer available in the United States. As a diuretic, benzthiazide inhibits active chloride reabsorption at the early distal tubule via the Na-Cl cotransporter, resulting in an increase in the excretion of sodium, chloride, and water. The following is a list of possible side effects that may occur from all constituting ingredients of Exna Tablet: vomiting, diarrhoea, photosensitivity reactions, increased in uric acid concentrations, megaloblastic anaemia, thrombocytopenia. Exna tablet may interact with the following drugs and products: ACE inhibitors, angiotensin II receptor antagonists, potassium-sparing diuretics.

Dimetindene (trade name Fenistil; other name dimethindene maleate) is a potent antipruritic antihistamine, characterized by the small size of its effective dose and its rapidity of action. Dimetindene is an antihistamine/anticholinergic that is a selective H1 antagonist. Its effect sets in after 20 to 60 minutes and lasts several hours. Dimetindene drops as well as Dimetindene syrup is particularly indicated in pediatric practice. Dimetindene is indicated as symptomatic treatment of allergic reactions: urticaria, allergies of the upper respiratory tract such as hay fever and perennial rhinitis, food, and drug allergies; pruritus of various origins, except pruritus due to cholestasis; insect bites. Dimetindene is also indicated for pruritus in eruptive skin diseases such as chicken-pox. Dimetindene can be as an adjuvant in eczema and other pruriginous dermatoses of allergic origin.
