Roflumilast is a specific phosphodiesterase type (4PDE4) inhibitor indicated for use as a treatment to reduce the risk of COPD exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations.
Rilpivirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) which is used for the treatment of HIV-1 infections in treatment-naive patients. It is active against wild-type and NNRTI-resistant HIV-1. Rilpivirine is a diarylpyrimidinethat inhibits HIV-1 replication by non-competitive inhibition of HIV-1 reverse transcriptase (RT). Rilpivirine does not inhibit the human cellular DNA polymerases α, β and γ.
Vandetanib, 4-anilinoquinazoline, is an anti-cancer drug that with the potential for use in a broad range of tumour types. In 2011 vandetanib (trade name Caprelsa) was approved by the FDA to treat nonresectable, locally advanced, or metastatic medullary thyroid cancer in adult patients. In vitro studies have shown that vandetanib inhibits the tyrosine kinase activity of the EGFR and VEGFR families, RET, BRK, TIE2, and members of the EPH receptor and Src kinase families. These receptor tyrosine kinases are involved in both normal cellular function and pathologic processes such as oncogenesis, metastasis, tumor angiogenesis, and maintenance of the tumor microenvironment. Vandetanib was shown to inhibit epidermal growth factor (EGF)-stimulated receptor tyrosine kinase phosphorylation in tumor cells and endothelial cells and VEGF-stimulated tyrosine kinase phosphorylation in endothelial cells. Vandetanib administration reduced tumor cell-induced angiogenesis, tumor vessel permeability, and inhibited tumor growth and metastasis in mouse models of cancer.
Cabazitaxel (JEVTANA®) is an antineoplastic agent belonging to the taxane class and is used to treat people with prostate cancer that has progressed despite treatment with docetaxel. It is prepared by semi-synthesis with a precursor extracted from yew needles (10-deacetylbaccatin III). Cabazitaxel (JEVTANA®) is a microtubule inhibitor. It binds to tubulin and promotes its assembly into microtubules while simultaneously inhibiting disassembly. This leads to the stabilization of microtubules, which results in the inhibition of mitotic and interphase cellular functions. The cell is then unable to progress further into the cell cycle, being stalled at metaphase, thus triggering apoptosis of the cancer cell.

ERIBULIN MESYLATE (HALAVEN®) is a microtubule dynamics inhibitor. It is a synthetic analog of halichondrin B, a product isolated from the marine sponge Halichondria okadai. ERIBULIN MESYLATE (HALAVEN®) inhibits the growth phase of microtubules without affecting the shortening phase and sequesters tubulin into nonproductive aggregates. It exerts its effects via a tubulin-based antimitotic mechanism leading to G2/M cell-cycle block, disruption of mitotic spindles, and, ultimately, apoptotic cell death after the prolonged mitotic blockage. ERIBULIN MESYLATE (HALAVEN®) is indicated for the treatment of patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens for the treatment of metastatic disease. It is also indicated for the treatment of patients with unresectable or metastatic liposarcoma who have received a prior anthracycline-containing regimen.
Alcaftadine is a broad-spectrum antihistamine displaying a high affinity for histamine H1 and H2 receptors and a lower affinity for H4 receptors. It also exhibits modulatory action on immune cell recruitment and mast cell stabilizing effects. Alcaftadine is an inhibitor of the release of histamine from mast cells. Decreased chemotaxis and inhibition of eosinophil activation has also been demonstrated. LASTACAFT® (alcaftadine ophthalmic solution) indicated for the prevention of itching associated with allergic conjunctivitis.
Everolimus is a derivative of Rapamycin (sirolimus), it is a mTOR inhibitor that binds with high affinity to the FK506 binding protein-12 (FKBP-12), thereby forming a drug complex that inhibits the activation of mTOR. This inhibition reduces the activity of effectors downstream, which leads to a blockage in the progression of cells from G1 into S phase, and subsequently inducing cell growth arrest and apoptosis. Everolimus also inhibits the expression of hypoxia-inducible factor, leading to a decrease in the expression of vascular endothelial growth factor. The result of everolimus inhibition of mTOR is a reduction in cell proliferation, angiogenesis, and glucose uptake. Everolimus is indicated for the treatment of postmenopausal women with advanced hormone receptor-positive, HER2-negative breast cancer (advanced HR+ BC) in combination with exemestane, after failure of treatment with letrozole or anastrozole. Indicated for the treatment of adult patients with progressive neuroendocrine tumors of pancreatic origin (PNET) with unresectable, locally advanced or metastatic disease. Indicated for the treatment of adult patients with advanced renal cell carcinoma (RCC) after failure of treatment with sunitinib or sorafenib. Indicated for the treatment of adult patients with renal angiomyolipoma and tuberous sclerosis complex (TSC), not requiring immediate surgery. Indicated in pediatric and adult patients with tuberous sclerosis complex (TSC) for the treatment of subependymal giant cell astrocytoma (SEGA) that requires therapeutic intervention but cannot be curatively resected. Everolimus is marketed by Novartis under the tradenames Zortress (USA) and Certican (Europe and other countries) in transplantation medicine, and as Afinitor (general tumours) and Votubia (tumours as a result of TSC) in oncology. Everolimus is also available from Biocon, with the brand name Evertor, from Natco Pharma, with the brand name Temonat, from Ranbaxy Laboratories, with the brand name of Imozide, from Emcure Pharmaceuticals, with the brand name of Temcure, among over 20 different brands.
Artemether is an antimalarial agent used to treat acute uncomplicated malaria. It is administered in combination with lumefantrine for improved efficacy against malaria. Artemether is rapidly metabolized into an active metabolite dihydroartemisinin (DHA). The antimalarial activity of artemether and DHA has been attributed to endoperoxide moiety. Artemethe involves an interaction with ferriprotoporphyrin IX (“heme”), or ferrous ions, in the acidic parasite food vacuole, which results in the generation of cytotoxic radical species. The generally accepted mechanism of action of peroxide antimalarials involves interaction of the peroxide-containing drug with heme, a hemoglobin degradation byproduct, derived from proteolysis of hemoglobin. This interaction is believed to result in the formation of a range of potentially toxic oxygen and carbon-centered radicals. Other mechanisms of action for artemether include their ability to reduce fever by production of signals to hypothalamus thermoregulatory center. Now, recent research has shown the presence of a new, previously unknown cyclooxygenase enzyme COX-3, found in the brain and spinal cord, which is selectively inhibited by artemether, and is distinct from the two already known cyclooxygenase enzymes COX-1 and COX-2. It is now believed that this selective inhibition of the enzyme COX-3 in the brain and spinal cord explains the ability of artemether in relieving pain and reducing fever which is produced by malaria. The most common adverse reactions in adults (>30%) are headache, anorexia, dizziness, asthenia, arthralgia and myalgia.
Pralatrexate (PDX or 10-propargyl-10-deazaaminopterin) is a folate analogue that is internalised by the reduced folate carrier 1 (RFC-1) protein, and polyglutamylated by the enzyme folylpolyglutamyl synthetase (FPGS), resulting in accumulation of the antifolate. Pralatrexate, a methotrexate analogue, is intended as an inhibitor of dihydrofolate reductase (DHFR), an enzyme which catalyses the reduction of dihydrofolic acid to tetrahydrofolic acid. Inhibition of DHFR leads to a depletion of intracellular reduced folate stores, thereby leading to a disruption of DNA synthesis. Preclinical studies in vitro and in models of B-cell lymphomas, T-cell lymphomas and NSCLC indicated that pralatrexate exhibited antitumor activity that was superior to the activity of other antifolates. FOLOTYN (pralatrexate injection) is indicated for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma.
Dronedarone is an antiarrhythmic that is FDA approved for the treatment of atrial fibrillation in patients in sinus rhythm with a history of paroxysmal or persistent atrial fibrillation (AF). Dronedarone is multichannel blocker. Common adverse reactions include abdominal pain, diarrhea, indigestion, nausea, vomiting, asthenia and raised serum creatinine. Dronedarone has potentially important pharmacodynamics interactions: Digoxin: Consider discontinuation or halve dose of digoxin before treatment and monitor; Calcium channel blockers (CCB): Initiate CCB with low dose and increase after ECG verification of tolerability; Beta-blockers: May provoke excessive bradycardia, Initiate with low dose and increase after ECG verification of tolerability.
