Pharmacology

Ranolazine, is an antianginal medication.
Food and Drug Administration(FDA) for the treatment ofchronic angina pectoris.
 Ranolazine, a partial fatty acid oxidation inhibitor,shifts ATP production from fatty acid to more oxygen-efficient carbohydrate
oxidation. Inhibition of fatty acid oxidation (e.g., with etomoxir or ranolazine) was also found to sensitize human leukemia cells to
apoptosis induction.

There are five main classes in the Singh Vaughan Williams classification of
antiarrhythmic agents:
Class I agents interfere with the sodium (Na +)channel.
Class II agenFluoxetinei-sympathetic nervous system agents. Most agents in this class are beta blockers.
Class III agents affect potassium (K +) efflux.
Class IV agents affect calcium channels and the AVnode .
Class V agents work by other or unknown
mechanisms.

DABIGATRAN is an oral anticoagulant from the class of the direct thrombin inhibitors . It is used for various clinical indications, and in some cases it offers an alternative to warfarin as the preferred orally
administered anticoagulant ("blood thinner"),
Mechanism of action
Ingested orally, dabigatran is a competitive and reversible direct thrombin inhibitor. Bivalent
Hirudin and derivatives were originally discovered in
Hirudo medicinalis:
Hirudin
Bivalirudin (transient inhibition - is cleaved by thrombin)
Lepirudin
Desirudin
Univalent
Univalent DTIs include:

Pegvisomant (trade name Somavert) is a growth hormone receptor antagonist used in the treatment of acromegaly.[1] It is used if the tumor of the pituitary gland causing the acromegaly cannot be controlled with surgery or radiation, and the use of somatostatin analogues is unsuccessful. It is delivered as a powder
that is mixed with water and injected under the skin
Pegvisomant blocks the action of growth hormone at
the growth hormone receptor to reduce the production of IGF-1.[3][4] IGF-1 is responsible for most of the symptoms of acromegaly thus normalising its levels is effective to control the symptoms. Side effects Side effects of Pegvisomant include reactions at the injection site, swelling of the limbs, chest pain, hypoglycemia, nausea and hepatitis. Blocking of the growth hormone's receptor reduces feedback control of the growth hormone regulation leading to approximately doubled GH levels
