Pralidoxime is a cholinesterase reactivator used as the antidote to organophosphate pesticides or acetylcholinesterase inhibitors (nerve agents) in conjunction with atropine and diazepam. Organophosphates bind to the esteratic site of acetylcholinesterase, which results initially in reversible inactivation of the enzyme. Acetylcholinesterase inhibition causes acetylcholine to accumulate in synapses, producing continuous stimulation of cholinergic fibers throughout the nervous systems. If given within 24 hours after organophosphate exposure, pralidoxime reactivates the acetylcholinesterase by cleaving the phosphate-ester bond formed between the organophosphate and acetylcholinesterase. Pralidoxime is indicated as an adjunct in the treatment of moderate and severe poisoning caused by organophosphate pesticides that have anticholinesterase activity or by chemicals with anticholinesterase activity such as some chemicals used as nerve agents during chemical warfare. Pralidoxime is also indicated as an adjunct in the management of the overdose of cholinesterase inhibitors, such as ambenonium, neostigmine, and pyridostigmine, used in the treatment of myasthenia gravis. Pralidoxime, used in conjunction with atropine, reverses nicotinic effects, such as muscle weakness and fasciculation, respiratory depression, and central nervous system (CNS) effects, associated with toxic exposure to organophosphate anticholinesterase pesticides and chemicals and with cholinesterase inhibitor overdose. Atropine, by antagonizing the action of cholinesterase inhibitors at muscarinic receptor sites, reverses muscarinic effects, such as tracheobronchial and salivary secretion, bronchoconstriction, bradycardia, and, to a moderate extent, CNS effects.

Lincomycin (LINCOCIN®) is an antibiotic produced by Streptomyces lincolnensis (Streptomycetaceae family). It has been used in the treatment of staphylococcal, streptococcal, and Bacteroides fragilis infections. Lincomycin (LINCOCIN®) inhibits protein synthesis in susceptible bacteria by binding to the 50S subunits of bacterial ribosomes and preventing peptide bond formation upon transcription. It is usually considered bacteriostatic, but may be bactericidal in high concentrations or when used against highly susceptible microorganisms.

Oxymetazoline is an adrenergic alpha-agonist, direct acting sympathomimetic, used as a vasoconstrictor to relieve nasal congestion The sympathomimetic action of oxymetazoline constricts the smaller arterioles of the nasal passages, producing a prolonged (up to 12 hours), gentle and decongesting effect. Oxymetazoline elicits relief of conjunctival hyperemia by causing vasoconstriction of superficial conjunctival blood vessels. The drug's action has been demonstrated in acute allergic conjunctivitis and in chemical (chloride) conjunctivitis. Oxymetazoline is self-medication for temporary relief of nasal congestion associated with the common cold, hay fever, or other upper respiratory allergies. Oxymetazoline is available over-the-counter as a topical decongestant in the form of oxymetazoline hydrochloride in nasal sprays such as Afrin, Operil, Dristan, Dimetapp, oxyspray, Facimin, Nasivin, Nostrilla, Sudafed OM, Vicks Sinex, Zicam, SinuFrin, and Mucinex Full Force. Due to its vasoconstricting properties, oxymetazoline is also used to treat nose bleeds and eye redness.

Nalidixic acid is a quinolone antibacterial indicated for the treatment of urinary tract infections. Nalidixic acid has marked antibacterial activity against gram-negative bacteria including Enterobacter species, Escherichia coli, Morganella Morganii; Proteus Mirabilis, Proteus vulgaris, and Providencia rettgeri. Pseudomonas species are generally resistant to the drug. It is suggested that nalidixic acid acts by inhibiting bacterial DNA gyrase.

Beta-carotene is found in many foods and is sold as a dietary supplement. Beta-carotene is a carotenoid, weak antioxidant; precursor of vitamin A, which is essential for vision and growth. Used to reduce the severity of photosensitivity reactions in patients with erythropoietic protoporphyria (EPP). Has been used in high-dose antioxidant supplements containing ascorbic acid and vitamin E with zinc in high-risk patients with age-related macular degeneration. Beta-carotene is also used to decrease asthma symptoms caused by exercise; to prevent certain cancers, heart disease, cataracts; and to treat AIDS, alcoholism, Alzheimer’s disease, depression, epilepsy, headache, heartburn, high blood pressure, infertility, Parkinson’s disease, rheumatoid arthritis, schizophrenia, and skin disorders including psoriasis and vitiligo.

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.

Lapyrium, or lapirium, as the chloride salt lapirium chloride (INN) or lapyrium chloride (USAN), is a cationic surfactant that is used in cosmetic personal care products as a biocide and antistatic agent. A 50% solution of Lapyrium Chloride produced slight to moderate erythema. Lapyrium is also used in waste-water treatment and corrosion inhibition formulations.

Trioxsalen (trimethylpsoralen, trioxysalen or trisoralen) is a furanocoumarin and a psoralen derivative. It is obtained from several plants, mainly Psoralea corylifolia. Like other psoralens it causes photosensitization of the skin. It is administered either topically or orally in conjunction with UV-A (the least damaging form of ultraviolet light) for phototherapy treatment of vitiligo1 and hand eczema.2 After photoactivation it creates interstrand cross-links in DNA, which can cause programmed cell death unless repaired by cellular mechanisms. In research it can be conjugated to dyes for confocal microscopy and used to visualize sites of DNA damage.3 The compound is also being explored for development of antisense oligonucleotides that can be cross-linked specifically to a mutant mRNA sequence without affecting normal transcripts differing at even a single base pair.Trioxsalen was discontinued by the manufacturer in December 2002.

Ethylestrenol (INN, USAN, BAN) (brand names Maxibolin, Orabolin), or ethylnandrol (JAN), also known as 17α-ethyl ester-4-en-17β-ol or as 3-deketo-17α-ethyl-19-nortestosterone, is an anabolic-androgenic steroid (AAS) with some progestogenic activity, and low androgenic activity. It is a 17α-ethylated derivative of nandrolone and lacks the 3-keto group. It was described in the literature in 1959 and approved in 1964 for testosterone deficiency in male patients.
