 Carvedilol

Brand name:- Carvil, carloc, carvas , Oricar  tab.

Carvedilol is an alpha and beta blocker. It works by slowing down the heart rate and relaxing blood vessels which makes the heart more efficient at pumping blood around the body.

Pharmacodynamic:- 

Carvedilol reduces tachycardia through beta adrenergic antagonism and lowers blood pressure through alpha-1 adrenergic antagonism. It has a long duration of action as it is generally taken once daily and has a broad therapeutic index as patients generally take 10-80mg daily. Patients taking carvedilol should not abruptly stop taking this medication as this may exacerbate coronary artery disease.

Mechanism of action:- 

Carvedilol is a cardiovascular agent for the treatment of CHF that combines beta - adrenoceptor blockade and vasodilation in a single racemic mixture . Non selective beta - adrenoceptor blocking activity present in the S(-)  enantiomer and alpha 1 - adrenoceptor blocking activity in present at equal potency in both the  R(+) and S(-)  enantiomer . Carvedilol has no intrinsic sympathomimetic activity. It's action on beta - receptors 10 time stronger than alpha - 1 receptors.

Used:-  

Used in the treatment of Hypertension (high blood pressure), Angina (heart-related chest pain) and Heart failure.

side effects:- 

Fatigue, Dizziness, Hypotension (low blood pressure), Diarrhea, Increased glucose level in blood, Weight gain, Slow heart rate, Weakness, Nausea.

Dose:-

CHF : Strat with 3.125 BD for 2 weeks,if well tolerated gradually increase to max. Of 25mg BD.
Hypertension/angina: 6.25 mg BD intially, titrate to max of 25mg BD.

Chlorthalidone Uses, Side Effects, and More....

 Chlorthalidone  Brand name:- Hythalton 50,100mg , Hydrazide, Thalizide ( 12.5, 25) . Chlorthalidone is a diuretic which lowers blood pressure by removing extra water and certain electrolytes from the body. Over time it also relaxes blood vessels and improves blood flow. Pharmacodynamic:- Not 🚫 available.  Pharmacokinetics:- Chlortalidone is slowly absorbed from the gastrointestinal tract after oral ingestion. It has a long half-life and therefore a prolonged diuretic action, which results in continued diuretic effects despite a skipped dose. This prolonged action of chlortalidone despite missing doses may account for the higher efficacy of chlortalidone compared to the shorter half-life medication, hydrochlorothiazide. Chlortalidone is eliminated from the body mostly by the kidney, as unchanged drug. Thus, in persons with diminished kidney function, the clearance of chlortalidone is reduced and the elimination half-life is increased. As with other thiazide diuretics, ch...

Chlordiazepoxide Uses, Side Effects, and More

 Chlordiazepoxide Brand name:- Librium 10, 25 mg tabs; Equilibrium 10mg tab. Chlordiazepoxide is a benzodiazepine. It works by increasing the action of a chemical messenger (GABA) which suppresses the abnormal and excessive activity of the nerve cells in the brain. Pharmacodynamic:-  Chlordiazepoxide has antianxiety, sedative, appetite-stimulating and weak analgesic actions. The drug seems to block EEG arousal from stimulation in the brain stem reticular formation. The drug has been studied extensively in many species of animals and these studies are suggestive of action on the limbic system of the brain, which recent evidence indicates is involved in emotional responses. Hostile monkeys were made tame by oral drug doses which did not cause sedation. Chlordiazepoxide revealed a "taming" action with the elimination of fear and aggression. The taming effect of chlordiazepoxide was further demonstrated in rats made vicious by lesions in the septal area of the brain. The drug dos...
