WO2008067465A1 OR US8084605  IS THE PATENT USED AND WITH FORM “A” AND AMORPHOUS FORM
Active pharmaceutical ingredients (APIs), frequently delivered to the patient in the solid-state as part of an approved dosage form, can exist in such diverse solid forms as polymorphs, pseudopolymorphs, salts, co-crystals and amorphous solids. Various solid forms often display different mechanical, thermal, physical and chemical properties that can remarkably influence the bioavailability, hygroscopicity, stability and other performance characteristics of the drug.
Hence, a thorough understanding of the relationship between the particular solid form of an active pharmaceutical ingredient (API) and its functional properties is important in selecting the most suitable form of the API for development into a drug product. In past decades, there have been significant efforts on the discovery, selection and control…

CHINESE MEDICINE-Xuezhikang , A blood lipid regulator

New Drug Approvals

Xuezhikang

Xuezhikang, the extract of red yeast rice, has been widely used as a Chinese traditional medicine for the therapy of patients with cardiovascular diseases. It contains natural Lovastatin and its homologues, as well as unsaturated fatty acids, flavonoids, plant sterols and other biologically active substances

The product is a world-recognized blood lipid regulator, which is made by extracting from “specially-made red yeast rice”. It combines modern high-tech biotechnology with traditional Chinese medicine, which can safely and effectively regulate blood lipids in a comprehensive way with proven curative effects and reliable safety.

Pharmacological Effects: the product can reduce blood cholesterol, triglycerides, low density lipoprotein cholesterol, improve high density lipoprotein cholesterol, inhibit atherosclerotic plaque formation, and protect vascular endothelial cells; and inhibit lipid deposition in the liver. The large-scale evidence-based research has proven that long-term use of XUEZHIKANG can greatly reduce the risk of CHD occurrence and decrease the mortality. XUEZHIKANG…

Zucapsaicin (Zuacta)

New Drug Approvals

Chemical structure of zucapsaicin

Zucapsaicin (Zuacta), cas 25775-90-0

Chemical name: (Z)-8-methyl-N-vanillyl-6-nonenamide
Molecular formula: C18H27NO3
Molecular mass: 305.41

E merck

Civamide, cis-Capsaicin,

Civanex (zucapsaicin) cream is a TRPV-1 modulator in development for the treatment of signs and symptoms of osteoarthritis of the knee.
Zucapsaicin, the cis-isomer of the natural product capsaicin, is a
topical analgesic that was initially developed by Winston Pharmaceuticals
and approved in Canada in July 2010 for the treatment of
severe pain in adults with osteoarthritis of the knee.

Bronson, J.; Dhar, M.; Ewing, W.; Lonberg, N. In Annual Reports in MedicinalChemistry; John, E. M., Ed.; Academic Press, 2011; Vol. 46, p 433.

The advantagesof zucapsaicin compared with naturally-occurring capsaicin, are reported to be a lesser degree of local irritation (stinging, burning,

erythema) in patients and a greater degree of efficacy in preclinical
animal models of pain.

ATCvet code QA08AB91

Dirlotapide is a drug used to treat obesity in dogs. It is manufactured by Pfizer and marketed as Slentrol.

It works as a selective microsomal triglyceride transfer protein (MTTP) inhibitor. This blocks the assembly and release of lipoproteins into the bloodstream, thereby reducing fat absorption. It also elicits a satiety signal from lipid-filled cells lining the intestine.

It is supplied as an oral solution. It is not intended for use in humans, cats, or parrots.

On January 5 2007, the U.S. Food and Drug Administration (FDA) approved Slentrol, the first time the FDA has approved a drug for obese dogs.[1]

Dirlotapide is used to manage obesity in dogs and helps…
