Cefozopran hydrochloride is a third-generation cephalosporin that was launched for the treatment of severe infections in immunocompromised patients caused by staphylococci and enterococci. While it shows a very broad antibacterial spectrum against Gram-positive and Gram-negative organisms, it is particularly potent against S. aureus, Enterococcus faecalis, P. aeruginosa, and Citrobacter freundii. It is resistant to hydrolysis by most chromosomal and plasmid mediated β-lactamases and is reported to be active against respiratory, urinary tract, obstetrical, gynecological, soft tissue, and surgical infections. Similar to β-lactams, cephalosporins interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBP’s are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to cephalosporins is commonly due to cells containing plasmid encoded β-lactamases.

Mebhydrolin (INN) or mebhydroline is a histamine H1-receptor antagonist. It is not available in the United States, but it is available in various other countries under the brand names Bexidal and Diazolin. It is used for symptomatic relief of allergic symptoms caused by histamine release, including nasal allergies and allergic dermatosis.

Etodroxizine is a first-generation antihistamine of the diphenylmethane and piperazine classes. It is a sleep-inducing agent. Etodroxizine in combination with methaqualone had a somewhat stronger surpressive effect upon REM-sleep than methaqualone alone.

Morinamide is a second line anti-tuberculous agent. In vitro morinamide demonstrated clear dose-dependent bacteriostatic and bactericidal activities. The anti-mycobacterial effect of morinamide was the same as pyrazinamide and was dependent on the acidity of medium (pH 5.6). Liver function test abnormalities following morinamide therapy are usually mild, and onset of jaundice is extremely uncommon. It has been given orally as the hydrochloride in the treatment of tuberculosis.

Imipraminoxide (brand names Imiprex, Elepsin) is a tricyclic antidepressant and imipramine metabolite that was used in Europe for the treatment of depression. In comparison with the imipramine, Imipraminoxide efficacy was identical to imipramine. However, in clinical trials, imipraminoxide was found to have a faster onset of action, and fewer and less marked side effects, including diminished orthostatic hypotension and anticholinergic effects like dry mouth, sweating, dizziness, and fatigue. Imipraminoxide's pharmacology has not been well elucidated, but based on its very close relationship with imipramine, it likely acts as a serotonin and norepinephrine reuptake inhibitor and serotonin, adrenaline, histamine, and muscarinic acetylcholine receptor antagonist, though with weaker antiadrenergic and anticholinergic actions

Rupatadine is characterised as a non-sedating H1 anti-histamine and platelet-activating factor (PAF) receptor antagonist. Rupatadine is indicated for the treatment of allergic rhinitis and urticaria. Rupatadine is a safe and well tolerated drug in patients over 2 years old, with no central nervous system or cardiovascular effects and it can be taken with or without foods.

Framycetin is a component of neomycin that is produced by Streptomyces fradiae. Framycetin is used for the treatment of bacterial eye infections such as conjunctivitis. Framycetin is an antibiotic. It is not active against fungi, viruses and most kinds of anaerobic bacteria. Framycetin works by binding to the bacterial 30S ribosomal subunit, causing misreading of t-RNA, leaving the bacterium unable to synthesize proteins vital to its growth. Framycetin is useful primarily in infections involving aerobic bacteria bacteria. Framycetin binds to specific 30S-subunit proteins and 16S rRNA, four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to interference with the initiation complex, misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes. Framycetin is a component of SOFRACORT (Framycetin sulphate - Gramicidin-dexamethasone), indicated for the treatment of blepharitis and infected eczema of the eyelid; allergic, infective and rosacea conjunctivitis; rosacea keratitis; scleritis and episcleritis; iridocyclitis, and other inflammatory conditions of the anterior segment of the eye, as well as otitis externa (acute and chronic) and other inflammatory and sebhorrheic conditions of the external ear.

Carpipramine (Prazinil, Defekton) is an atypical antipsychotic used for the treatment of schizophrenia and anxiety in France and Japan. In addition to its neuroleptic and anxiolytic effects, carpipramine also has hypnotic properties. In september 2014 L'ANSM decided to withdraw the marketing of Prazinil (carpipramine).

Zacopride is a potent antagonist at the 5-HT3 receptor and an agonist at the 5-HT4 receptor with antiemetic, anxiolytic and nootropic effects in animal models. Zacopride also has pro-respiratory effects, both reducing sleep apnea and reversing opioid-induced respiratory depression in animal studies. Zacopride has been tested in clinical trials for the treatment of schizophrenia but was found unsuccessful.

Butamisole is an injectable imidazothiazoles anthelmintic. In dogs it is used for the treatment of infections with whipworms (Trichuris vulpis ), and the hookworm (Ancylostoma caninum ). Nicotinic acetylcholine receptor agonist. Acts as agonist at nicotinic Ach receptor of nematode à ganglionic stimulation causes sustained muscle contraction initially followed by depolarising neuro muscular blockade which in turn leads to spastic paralysis.
