Membrane stabilizers are used to treat arrhythmia. They act directly on sodium ion channels to restrict the entry of sodium ions into cardiac muscle cells. These drugs therefore act to slow the rate of depolarization, which is more marked in ectopic pacemakers, allowing the SA node to regain control of cardiac rhythm. Lidocaine is ineffective orally and its use is restricted to preventing and treating ventricular arrhythmia after myocardial infarction. (Lidocaine by virtue of the same mechanism of action is used as a local anaesthetic.

This action terminates the growing viral DNA strand. Because of HIV resistance, several similar drugs have been developed, including abacavir and lamivudine. All drugs in this group are toxic, common side effects being gastrointestinal disturbances, anorexia, pancreatitis and liver damage. Non-nucleoside reverse transcriptase inhibitors such as efavirenz and nevirapine are similar and have a similar profile of adverse effects. Viral protease is essential in retroviruses for the production of mature viral particles.

Use of systemic antipsoriatic drugs is generally under supervision of a dermatologist in a hospital setting. Methotrexate is the most common treatment for resistant and widespread psoriasis. Its main furosemide cost in india are cytotoxic and immunosuppressant.

Atrial flutter describes the condition where there is rapid but regular, beating of the atria of between Atrial fibrillation is said to occur when there is rapid but disordered contraction of the atria of between Paroxysmal supraventricular tachycardia is an intermittent increase in the rate of atrial contraction. Ectopic beats are extra beats caused by the depolarization of a focus of cells other than the SA node. Ventricular fibrillation is the asynchronous contraction of the ventricles, which rapidly leads to circulatory failure if not treated as an emergency. Heart block occurs if there is AV node damage; in this situation, the atria and ventricles beat independently reducing the efficiency of the heart as a pump. Asystole is when the heart stops beating.

Chemotherapy also buys lasix canada to treatment of cancers.
