Carbamazepine is an analgesic, anti-epileptic agent that is FDA approved for the treatment of epilepsy, trigeminal neuralgia. It appears to act by reducing polysynaptic responses and blocking the post-tetanic potentiation. It depresses thalamic potential and bulbar and polysynaptic reflexes, including the linguomandibular reflex in cats. Commonly reported side effects of carbamazepine include: dizziness, drowsiness, nausea, ataxia, and vomiting. Carbamazepine is a potent inducer of hepatic CYP1A2, 2B6, 2C9/19, and 3A4 and may reduce plasma concentrations of concomitant medications mainly metabolized by CYP1A2, 2B6, 2C9/19, and 3A4 through induction of their metabolism, like Boceprevir, Cyclophosphamide, Aripiprazole, Tacrolimus, Temsirolimus and others.
Doxycycline hyclate (Vibramycin, Periostat, Vibra-Tabs) is salt of tetracycline antibiotic Doxycycline, that used to treat many kinds of infections, like dental, skin, respiratory, and urinary tract infections. It also treats acne, Lyme disease, malaria, and certain sexually transmitted diseases. Doxycycline hyclate is a light-yellow crystalline powder which is soluble in water, while doxycycline monohydrate is very slightly soluble in water. Doxycycline is bacteriostatic, inhibiting bacterial protein synthesis due to disruption of transfer RNA and messenger RNA at ribosomal sites. Doxycycline hyclate is indicated for use in the treatment of chronic adult periodontitis for a gain in clinical attachment, reduction in probing depth, and reduction in bleeding on probing.

Prilocaine is a local anesthetic that is similar pharmacologically to lidocaine. Prilocaine binds to the intracellular surface of sodium channels which blocks the subsequent influx of sodium into the cell. Action potential propagation and never function is, therefore, prevented. This block is reversible and when the drug diffuses away from the cell, sodium channel function is restored and nerve propagation returns. Prilocaine acts on sodium channels on the neuronal cell membrane, limiting the spread of seizure activity and reducing seizure propagation. The antiarrhythmic actions are mediated through effects on sodium channels in Purkinje fibers. Currently, Prilocaine is used most often for infiltration anesthesia in dentistry.
Melphalan, also known as L-phenylalanine mustard, phenylalanine mustard, L-PAM, or L-sarcolysin, is a phenylalanine derivative of nitrogen mustard. Melphalan is a bifunctional alkylating agent which produces a number of DNA adducts with the DNA interstrand crosslink (ICL) considered to be the critical cytotoxic lesion. Melphalan is used to treat different cancers including myeloma, melanoma and ovarian cancer.

The selenite anion is a selenium oxoanion with the chemical formula SeO2−3. A selenite (Se) is a compound that contains this ion. Sodium selenite is an inorganic form of the trace element selenium with potential antineoplastic activity. It was documented that Se deficiency observed in some countries and/or geographic regions (e.g. Keshan region in China), is associated with an increased morbidity and mortality of neoplastic diseases. To correct this problem a number of organic and inorganic selenium compounds were developed and tested. However, it is now firmly established that only an inorganic sodium selenite with four-valent Se, and not that with six-valent (selenate) cation shows anticancer activity. Selenite can undergo redox reaction, for example with protein's sulfhydryl groups expressed on the surface of tumor cells. In this way selenite prevents non-enzymatic formation of parafibrin that coats tumors cells and hence presents them as 'self' to the innate cellular immune system. Consequently, macrophages of the lymphatic system do not recognize neoplastic cells as 'foreign' bodies and spare them from the immune destruction. Sodium selenite also showed promise as a cost-effective, nontoxic anti-inflammatory agent. Treatment with sodium selenite lowers reactive oxygen species (ROS) production, causes a spontaneous reduction in lymphedema volume, increases the efficacy of physical therapy for lymphedema, and reduces the incidence of erysipelas infections in patients with chronic lymphedema. Limited evidence has been presented though that intakes of selenium greater than the amount needed to allow full expression of selenoproteins may have chemopreventive effects against cancer. Controlled intervention studies are needed to fully evaluate selenium as a cancer chemopreventive agent. The US Food and Drug Administration approved a selenium supplement to animal diets; the most common form is sodium selenite for pet foods.
