Levomepromazine (also known as methotrimeprazine) is a phenothiazine neuroleptic drug. It is sold in many countries under the generic name (levomepromazine) or under brand names such as Nozinan, Detenler and many more. Levomepromazine is an antipsychotic drug is commonly used as an antiemetic to alleviate nausea and vomiting in palliative care settings particularly in terminal illness. Levomepromazine is a phenothiazine with pharmacological activity similar to that of both chlorpromazine and promethazine. It has the histamine-antagonist properties of the antihistamines together with central nervous system effects resembling those of chlorpromazine. Levomepromazine's antipsychotic effect is largely due to its antagonism of dopamine receptors in the brain. In addition, it can block 5HT2 receptors and some others, like histamine, serotonin.

Conditions:

Dimethisterone (brand name Secrosteron) is an orally active progestational agent. It was developed by the British pharmaceutical company British Drug Houses and was first reported in the literature in 1959 with introduction for medical use as Secrosteron. Relative to ethisterone, it is 12 times as potent orally as a progestogen in animals (Clauberg test). It has an oral LD50 in mice of 7.65 g/kg, no apparent anabolic, androgenic properties and no significant effect on sodium, potassium or water excretion in saline loaded rats. Dimethisterone was introduced in the United States as an oral contraceptive for birth control in combination with ethinylestradiol under the brand name Oracon (25 mg dimethisterone, 100 ug ethinylestradiol) and was produced by Mead Johnson & Company (Evansville, Indiana) in 1974. This preparation was eventually found to be associated with a substantially increased risk of endometrial cancer in women, and is now no longer marketed.
Cloxacillin is a derivative of penicillin for the treatment of broad spectrum of bacterial infections. The drug exerts its action by inhiiting bacterial beta-lactamase (penicillin-binding proteins).

Cephalothin is a first generation, semisynthetic analogue of natural cephalosporin antibiotic. The in-vitro bactericidal action of Cephalothin results from inhibition of cell-wall synthesis. In general, Cephalothin has higher activity against Gram positive than Gram negative organisms. Cephalothin is primarily indicated in conditions like bone and joint infection, genitourinary tract infections, respiratory tract infections, soft tissue and skin infections and others. The severe or irreversible adverse effects of Cephalothin, which give rise to further complications, include nephrotoxicity, hemolytic anemia. Cephalothin produces potentially life-threatening effects, which include anaphylaxis, serum sickness syndrome. The symptomatic adverse reactions produced by Cephalothin are: rashes, urticaria, allergic reactions, thrombophlebitis, pain at injection site. Co-administration of diuretics, such as furanthril, ethacrynic acid and nephrotoxic antibiotics may increase the risk of renal damage. Reciprocal inactivation could be observed during in vitro mixing of Cephalothin with aminoglycosides.

Targets:


Idoxuridine is an antiviral agent use in keratitis caused by herpes simplex virus. As a prescription drug it comes as a 0.1% ophthalmic solution/drops (Herplex and Dendrid). The first studies of the compound for treatment of human herpes simplex started in early 1960s. Being a structural analog of thymidine idoxuridine inhibits viral DNA replication by substituting thymidine. The effect of idoxuridine results in the inability of the virus to reproduce and/or infect tissues. Idoxuridine also blocks viral thymidine kinase as its substrate analog.

Dicobalt edetate was developed as a cyanide antidote based on the known ability of cobalt to form stable complexes with cyanide. One current cobalt-based antidote available in Europe is dicobalt-EDTA, sold as Kelocyanor. This agent chelates cyanide as the cobalticyanide. This drug provides an antidote effect more quickly than formation of methemoglobin. It can be very toxic and cause seizures, upper airway oedema, chest pain, hypotension, vomiting, rashes and dyspnoea especially in those who have not be exposed to cyanide.
Methaqualone is a depressant that modulates the activity of the GABA receptors in the brain and nervous system. It promotes relaxation, sleepiness and sometimes a feeling of euphoria. It causes a drop in blood pressure and slows the pulse rate. These properties are the reason why it was initially thought to be a useful sedative and anxiolytic. Common side effects of Methaqualone include dizziness, nausea, vomiting, diarrhea, abdominal cramps, fatigue, itching, rashes, sweating, dry mouth, tingling sensation in arms and legs, seizures and its depressant effects include reduced heart rate and respiration. The drug became banned in many countries and was withdrawn from many markets in the early 1980s.
