Cefpodoxime Proxetil is an antibacterial with a broad spectrum activity. It is an oral, third generation cephalosporin, ester prodrug of the active free acid metabolite Cefpodoxime. It is active against most Gram-positive and Gram-negative organisms. It is commonly used to treat acute otitis media, pharyngitis, sinusitis, and gonorrhea. It also finds use as oral continuation therapy when intravenous cephalosporins (such as ceftriaxone) are no longer necessary for continued treatment. Currently, it is only marketed as generic preparations in the USA.

Cefoxitin Sodium is a semisynthetic cephamycin antibiotic resistant to beta-lactamase. It is derived from Cephamycin C and is highly resistance to β-lactamase inactivation. Also an antibacterial, cefoxitin sodium acts by adhering to bacterial penicillin-binding proteins, thereby inhibiting cell wall synthesis.

Cefotetan Hydrochloride is a second-generation cephalosporin that is active against some strains of β-lactamase producing bacteria. It shows anti-microbial activity against Gram-positive and Gram-negative bacteria; it is more efficacious against Gram-negative and anaerobic bacteria. Cefotetan Hydrochloride binds to penicillin-binding proteins and disrupts the cell wall synthesis.

Cefotaxime Sodium is the sodium salt form of cefotaxime, a beta-lactam, third-generation cephalosporin antibiotic with bactericidal activity. Cefotaxime sodium binds to and inactivates penicillin-binding proteins (PBP) located on the inner membrane of the bacterial cell wall. Inactivation of PBPs interferes with the cross-linking of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis. Compared to the second and first generation cephalosporins, cefotaxime sodium is more active against gram-negative bacteria and less active against gram-positive bacteria. It is effective against postoperative complications in surgical treatment of pulmonary, tracheal and mediastinal tumors.

Ceforanide is a semi-synthetic, broad-spectrum, beta-lactam, second-generation cephalosporin antibiotic with bactericidal activity. Ceforanide causes inhibition of bacterial cell wall synthesis by inactivating penicillin binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of the cell wall. This results in a reduction of cell wall stability and causes cell lysis.

Cefoperazone Sodium is the sodium salt form of cefoperazone and a semi-synthetic, broad-spectrum, beta-lactamase resistant, third-generation cephalosporin antibiotic with bactericidal activity. It is marketed by Pfizer under the name Cefobid. Cefoperazone sodium inhibits bacterial cell wall synthesis by inactivating penicillin binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of bacterial cell walls. This results in a reduction of cell wall stability and causes cell lysis. It is one of few cephalosporin antibiotics effective in treating Pseudomonas bacterial infections which are otherwise resistant to these antibiotics.

Cefmetazole is a second-generation, semi-synthetic, beta-lactam cephalosporin antibiotic with antibacterial activity.

PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity.

Cephacetrile is a broad-spectrum first-generation cephalosporin with antibiotic and antibacterial activity. Cephacetrile binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

Carprofen is a non-steroidal anti-inflammatory drug that veterinarians prescribe as a supportive treatment for various conditions. It provides day-to-day treatment for pain and inflammation from arthritis in geriatric dogs, joint pain, osteoarthritis, hip dysplasia, and other forms of joint deterioration. It is also used to relieve short-term post-operative pain, inflammation, and swelling after spaying, neutering, and other procedures. Carprofen reduces inflammation by inhibition of COX-2 and other sources of inflammatory prostaglandins. This is targeted protection, in that it does not interfere with COX-1 activity.

Carphenazine dimaleate is an antipsychotic agent, mainly used for the treatment of chronic schizophrenia.

Carglumic acid is an orphan drug, marketed by Orphan Europe under the trade name Carbaglu.

The initial daily dose ranges from 100 to 250 mg/kg, adjusted thereafter to maintain normal plasma levels of ammonia.

Carbachol is a cholinomimetic drug that binds and activates the acetylcholine receptor. Thus it is classified as a cholinergic agonist. It is primarily used for various ophthalmic purposes, such as for treating glaucoma, or for use during ophthalmic surgery. It is generally administered as an ophthalmic solution (i.e. eyedrops).

Buspirone HCl is an anxiolytic psychotropic drug of the azapirone chemical class. It is primarily used to treat generalized anxiety disorder (GAD). Unlike most drugs predominantly used to treat anxiety, buspirone's pharmacology is not related to benzodiazepines or barbiturates, and so does not carry the risk of physical dependence and withdrawal symptoms for which those drug classes are known.

Bupropion or bupropion hydrochloride, also known formerly as amfebutamone, is a medication primarily used as an antidepressant and smoking cessation aid. It is one of the most frequently prescribed antidepressants in the United States, although in many English-speaking countries, including the United Kingdom, Australia and New Zealand, this is an off-label use. Chemically, bupropion is in the aminoketone family. Bupropion serves as an atypical antidepressant different from most commonly prescribed antidepressants such as selective serotonin reuptake inhibitors (SSRIs). It is an effective antidepressant on its own, but is also popular as an add-on medication in cases of incomplete response to first-line SSRI antidepressants.

Buclizine is an antihistamine and anticholinergic of the piperazine derivative family. It is considered to be an antiemetic, similar to meclizine.

Bromfenac is a non-steroidal anti-inflammatory drug (NSAID) marketed in the US as an ophthalmic solution by ISTA Pharmaceuticals for short-term, local use. Prolensa and Bromday are the once-daily formulation of bromfenac, while Xibrom was approved for twice-daily administration. Bromfenac is indicated for the treatment of ocular inflammation and pain after cataract surgery, though it may be prescribed in an off-label manner by the physician. The high degree of penetration and potency of bromfenac can be attributed to the halogenation of the molecule: by adding a bromine moiety the NSAID becomes highly lipophilic which allows for rapid, sustained drug levels in the ocular tissues.

Bopindolol malonate is a non-selective, potent, long-acting beta adrenoceptor antagonist. It demonstrates inhibition of H2O2-induced lipid peroxdiation. Bopindolol malonate slowly dissociates into the active metabolites 4-(3-tert-butylamino-2-hydroxypropoxy)-2-methyl indole and 4-(3-tert-butylaminopropoxy)-2-carboxyl indole which both demonstrate potent β1-adrenoceptor blocking activity.
