Targets:
Methantheline is a synthetic quarternary ammonium antimuscarinic used to relieve cramps or spasms of the stomach, intestines, and bladder. It is indicated for the treatment of peptic ulcer disease, irritable bowel syndrome, pancreatitis, gastritis, biliary dyskinesia, pylorosplasm, and reflex neurogenic bladder in children. It can be used together with antacids or other medicines, such as H2-receptor antagonists, in the treatment of peptic ulcer. Methantheline bromide (diethyl-methyl [2-(9 xanthenyl carbonyloxy) ethyl] ammonium bromide) is marketed to treat neurogenic bladder instability. In comparison with atropine, it influences the parasympathetic nervous transmission more by ganglionic rather than peripheral muscarinic receptor blockade. Methantheline inhibits the muscarinic actions of acetylcholine on structures innervated by postganglionic cholinergic nerves as well as on smooth muscles that respond to acetylcholine but lack cholinergic innervation. Clinical effects after single therapeutic doses of 50-100 mg last for about 6 hours which is longer than after atropine. The drug relaxes smooth muscles of the gastrointestinal and urogenital tract. Furthermore, it inhibits bronchial, salivary and sweat glands secretion, lowers the production of gastric juice and disturbs accommodation. A recent randomised double-blind placebo-controlled study using a new commercial preparation of methantheline bromide (Vagantin, Germany) demonstrated significant sweat reduction and was evaluated as is an effective and safe treatment of axillary hyperhidrosis.

Dimoxyline is the synthetic analogue of papaverine, Acute toxicity studies show it to be less toxic than papaverine. No analgesic action and no tolerance development in experimental animals by repeated administration. But Dimoxyline does not appear to be as potent as papaverine in comparable dosage. Dimoxyline is indicated for the treatment of patients with angina pectoris. Also, significant amount of benefit was claimed in patients with acute or chronic phlebitis, arterial thrombosis or embolism, Raynaud’s phenomena and early thromboangiitis obliterans or arteriosclerosis obliterans. Detected adverse events are: nausea or abdominal cramps.

Diethylcarbamazine is used in humans, dogs and cats for the treatment of parasitic infections, including pulmonary eosinophilia, loiasis, and lymphatic filariasis. The exact mechanism of its action is unknown, however some studies showed the involvment of inducible nitric-oxide synthase and the cyclooxygenase pathway. Although there is no information on whether the drug is marketed in the USA and Europe, it is currently used in India.

Conditions:
Amodiaquine is a medication used to treat malaria, including Plasmodium falciparum malaria when uncomplicated. The mechanism of plasmodicidal action of amodiaquine is not completely certain. Like other quinoline derivatives, it is thought to inhibit heme polymerase activity. This results in accumulation of free heme, which is toxic to the parasites. The drug binds the free heme preventing the parasite from converting it to a form less toxic. This drug-heme complex is toxic and disrupts membrane function. The side effects of amodiaquine are generally minor to moderate and are similar to those of chloroquine. Rarely liver problems or low blood cell levels may occur. When taken in excess headaches, trouble seeing, seizures, and cardiac arrest may occur. After oral administration amodiaquine hydrochloride is rapidly absorbed,and undergoes rapid and extensive metabolism to desethylamodiaquine which concentrates in red blood cells. It is likely that desethylamodiaquine, not amodiaquine, is responsible for most of the observed antimalarial activity, and that the toxic effects of amodiaquine after oral administration may in part be due to desethylamodiaquine.
