Methicillin

Methicillin is an antibiotic related to penicillin and other beta-lactam containing antibiotics. It is often used to treat infections caused by bacteria carrying an antibiotic resistance, e.g., staphylococci. As methicillin is deactivated by gastric acid, it has to be administered by injection.

Uses Methicillin serves a purpose in the laboratory to determine antibiotic sensitivity in microbiological culture.

Ciclopirox:Ciclopirox is a synthetic antifungal agent for topical dermatologic use.

COAGULANTS

An agent that produces coagulation (Coagulation is a complex process by which blood forms clots).

ANTICOAGULANTS

An anticoagulant is a substance that prevents coagulation; that is, it stops blood from clotting.

Anticoagulants:

Calcium Chelators (sodium citrate, EDTA)

Heparin

Dalteparin Sodium (Fragmin) -Low molecular-weight heparin

Enoxaparin - Low molecular-weight heparin

Tinzaparin Sodium  - Low molecular-weight heparin

Warfarin

Lepirudin - recombinant form of the natural anticoagulant hirudin: potent and specific Thrombin inhibitor

Bivalirudin - analog of hirudin: potent and specific Thrombin inhibitor

Procoagulants:

Desmopressin acetate

Antiplatelet Drugs:

Acetylsalicylic Acid, Ticlopidine, Sulfinpyrazone, Abciximab , Clopidogrel bisulfate

Fibrinolytic Drugs:

Tissue Plasminogen Activator (t-PA, Activase), Streptokinase (Streptase),

Anistreplase, Urokinase

Antagonists:

Protamine sulfate, Aminocaproic acid

Pharmacological agents used to treat blood coagulation disorders fall in to three major categories:

1. Anticoagulants: Substances that prevent the synthesis of a fibrin network which inhibits coagulation and the formation of arterial thrombi and thromboembolic clots.

2. Antiplatelet agents: Substances that reduce the adhesion and aggregation of platelets.

3. Fibrinolytic agents: Substances that promote the destruction of already formed blood clots or thrombi by disrupting the fibrin mesh.

Drugs Used in Diabetes

Goals of diabetes treatment

lower serum glucose to physiologic range
keep insulin levels in physiologic range
eliminate insulin resistance

best initial step in management: weight loss, contractile-based exercise weight loss is more important for insulin sensitivity than is a low-carb diet

Modalities of diabetes treatment

Type I DM

insulin
low-sugar diet

Type II DM
exercise
diet
insulin

6 classes of drugs 

Insulin
Sulfonylureas -    Glyburide
Meglitinides  - Nateglinide
Biguanides    Metformin    
Glitazones (thiazolidinediones)    Pioglitazone
α-glucosidase inhibitors    Acarbose
GLP-1 mimetics (incretin mimetics)    Exenatide
Amylin analog    Pramlintide

BradyKinin

An endogenous vasodilator occurring in blood vessel walls. 
At least two distinct receptor types, B1 and B2, appear to exist for BradyKinin

Roles of bradykinin:

1) Mediator of inflammation and pain.
2) Regulation of microcirculation.
3) Their production is interrelated with clotting and fibrinolysin systems.
4) Responsible for circulatory change after birth.
5) Involved in shock and some immune reactions.
