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.

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...
