Generic Licensing News-SPIRAMYCIN Featured product


File:Spiramycin I.svg

SPIRAMYCIN

Spiramycin is a macrolide antibiotic. It is used to treat certain types of infections that are caused by bacteria. It is most commonly used to treat infections of the lung, skin, and mouth.

Spiramycin is sometimes used to treat gonorrhea for people who are allergic to penicillin. Spiramycin is also used as an alternative agent in the treatment of toxoplasmosis during pregnancy.

more info from wiki

Spiramycin is a macrolide antibiotic. It is used to treat toxoplasmosisand various other infections of soft tissues. Although used in Europe, Canada and Mexico,[1] spiramycin is still considered an experimental drug in the United States, but can sometimes be obtained by special permission from the FDA for toxoplasmosis in the first trimester of pregnancy.[2]

Spiramycin has been used in Europe since the year 2000 under thetrade name “Rovamycine”, produced by Rhone-Poulenc Rorer and Famar Lyon, France and Eczacibasi Ilae, Turkey. It also goes under the name Rovamycine in Canada (distributed by OdanLaboratories), where it is mostly marketed to dentists for mouth infections.

Spiramycin is a 16-membered ring macrolide (antibiotic). It was discovered in 1952 as a product of Streptomyces ambofaciens. As a preparation for oral administration it has been used since 1955, in 1987 also the parenteral form was introduced into practice. The antibacterial action involves inhibition of protein synthesis in the bacterial cell during translocation. Resistance to spiramycin can develop by several mechanisms and its prevalence is to a considerable extent proportional to the frequency of prescription in a given area. The antibacterial spectrum comprises Gram-positive cocci and rods, Gram-negative cocci and also Legionellae, mycoplasmas, chlamydiae, some types of spirochetes, Toxoplasma gondii and Cryptosporidium sp., Enterobacteria, pseudomonads and pathogenic moulds are resistant. Its action is mainly bacteriostatic, on highly sensitive strains it exerts a bactericide action. As compared with erythromycin, it is in vitro weight for weight 5 to 20 less effective, an equipotential therapeutic dose is, however, only double. This difference between the effectiveness in vitro and in vivo is explained above all by the great affinity of spiramycin to tissues where it achieves concentrations many times higher than serum levels. An important part is played also by the slow release of the antibiotic from the tissue compartment, the marked action on microbes in sub-inhibition concentrations and the relatively long persisting post-antibiotic effect. Its great advantage is the exceptionally favourable tolerance-gastrointestinal and general. It is available for parenteral and oral administration

Actavis to Launch Generic Epilepsy/Bipolar Drug


LAMOTRIGINE

 

PARSIPPANY, N.J., July 15, 2013 (AP) — Drugmaker Actavis Inc. said Monday it’s received U.S. approval to sell a generic version of Lamictal, a tablet for treating epilepsy and bipolar disorder.

Actavis, based in Parsippany, N.J., said the Food and Drug Administration has granted approval for it to sell lamotrigine tablets in doses of 25, 50, 100 and 200 milligrams.http://www.pharmalive.com/actavis-to-launch-generic-epilepsybipolar-drug

Lamotrigine, marketed in the US and most of Europe as Lamictal /ləˈmɪktəl/ byGlaxoSmithKline, is an anticonvulsant drug used in the treatment of epilepsy and bipolar disorder. It is also used off-label as an adjunct in treating depression. For epilepsy, it is used to treat focal seizures, primary and secondary tonic-clonic seizures, and seizures associated with Lennox-Gastaut syndrome. Like many other anticonvulsant medications, Lamotrigine also seems to act as an effective mood stabilizer, and has been the first U.S.Food and Drug Administration (FDA)-approved drug for this purpose since lithium, a drug approved almost 30 years earlier. It is approved for the maintenance treatment of bipolar type I. Chemically unrelated to other anticonvulsants (due to lamotrigine’s being aphenyltriazine), lamotrigine has many possible side-effects. Lamotrigine is generally accepted to be a member of the sodium channel blocking class of antiepileptic drugs,but it could have additional actions since it has a broader spectrum of action than other sodium channel antiepileptic drugs such as phenytoin and carbamazepine and is effective in the treatment of the depressed phase of bipolar disorder, whereas other sodium channel blocking antiepileptic drugs are not. In addition, lamotrigine shares few side-effects with other, unrelated anticonvulsants known to inhibit sodium channels, which further emphasizes its unique properties. Lamotrigine is inactivated by hepatic glucuronidation.

InnoPharma Inc. Announces Launch of Generic Cidofovir Injection in the United States


({[(S)-1-(4-amino-2-oxo-1,2-dihydropyrimidin-1-yl)-3-hydroxypropan-2-yl]oxy}methyl)phosphonic acid

Cidofovir

Cidofovir is an injectable antiviral medication for the treatment of cytomegalovirus (CMV)retinitis[1] in patients with AIDS. It suppresses CMV replication by selective inhibition of viral DNA polymerase and therefore prevention of viral replication and transcription.[2] It is an acyclic nucleoside phosphonate, and is therefore independent of phosphorylation by viral enzymes,[3] in contrast to, for instance, acyclovir.

Maintenance therapy with cidofovir involves an infusion only once every two weeks, making it a convenient treatment option. Because dosing is relatively infrequent, a permanent catheter is not necessary for infusions.

Cidofovir was discovered at the Institute of Organic Chemistry and Biochemistry, Prague, by Antonín Holý, and developed by Gilead Sciences and is marketed with the brand name Vistide by Gilead in the USA, and by Pfizer elsewhere.
