CLOMIPRAMINE Uses, Side Effects, and More

 CLOMIPRAMINE BRAND NAME:- CLOFRANIL, 10,25,50mg tab, 75mg SR tab. Clonil, anafranil 10,25mg tab.  CLOMIPRAMINE is a tricyclic antidepressant. It is used in adults to treat obsessive-compulsive disorder (OCD). It also treats muscular weakness (cataplexy) associated with repeat attacks of sleepiness (narcolepsy) and can manage depression that is unresponsive to other medicines. PHARMACODYANIMCS:- Clomipramine, a tricyclic antidepressant, is the 3-chloro derivative of Imipramine. It was thought that tricyclic antidepressants work exclusively by inhibiting the re-uptake of the neurotransmitters norepinephrine and serotonin by nerve cells. However, this response occurs immediately, yet mood does not lift for around two weeks. It is now thought that changes occur in receptor sensitivity in the cerebral cortex and hippocampus. The hippocampus is part of the limbic system, a part of the brain involved in emotions. Presynaptic receptors are affected: α1 and β1 receptors are sensitized...

CLOTRIMAZOLE Uses, Side Effects, and More

 CLOTRIMAZOLE BRAND NAME:- SURFAZ, CLODERM, 1℅ lotion, cream, powder; 100mg vaginal tab. CANDID 1℅  Cream, mouth paint, powder.  CLOTRIMAZOLE is an antifungal medication.

CYCLOPENTOLATE Uses, Side Effects, and More

 Cyclopentolate BRAND NAME:- CYLOMID EYE 0.5% , CYCLOGYL, CYCLOPENT 1%  Cyclopentolate is an anticholinergic , is potent and rapidly acting ; mydriasis and cycloplegia occur in 30 -60min and last about a day. It is preferred for cycloplegic refraction, but children may show tranisent behavioural abnormalities due to absorption of the drug after passage into the nasolacrimal duct. It is also used in iritis and uveitis.  PHARMACODYNAMICS:-  Cyclopentolate is an anti-muscarinic in the same class as atropine and scopolamine. Cyclopentolate blocks the receptors in the muscles of the eye (muscarinic receptors). These receptors are involved controlling the pupil size and the shape of the lens. Cyclopentolate thus induces relaxation of the sphincter of the iris and the ciliary muscles. When applied topically to the eyes, it causes a rapid, intense cycloplegic and mydriatic effect that is maximal in 15 to 60 minutes; recovery usually occurs within 24 hours. The cycloplegic an...

CYCLOPHOSPHAMIDE Uses, Side Effects, and More

 CYCLOPHOSPHAMIDE Brand Name:- Endoxan, Cycloxan 50mg tab; 200,500,1000mg inj.  CYCLOPHOSPHAMIDE , also known as cytophosphane among other names, is a medication used as chemotherapy and to suppress the immune system. As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma.  Pharmacodyanic:- Cyclophosphamide is an antineoplastic in the class of alkylating agents and is used to treat various forms of cancer. Alkylating agents are so named because of their ability to add alkyl groups to many electronegative groups under conditions present in cells. They stop tumor growth by cross-linking guanine bases in DNA double-helix strands - directly attacking DNA. This makes the strands unable to uncoil and separate. As this is necessary in DNA replication, the cells can no longer divide. In addition, these drugs add methyl or other alkyl groups onto molecules where they do not belong ...

CYCLOSERINE (Cs) Uses, Side Effects, and More

 CYCLOSERINE (Cs)  Brand Name:-  cyclorine, covering, Myser 250mg cap.  CYCLOSERINE (Cs)is a broad-spectrum  antibiotic. It kills bacteria by preventing them from forming their own protective covering (cell wall) which is required for their survival in the human body. Pharmacodynamic :-  Cycloserine, a broad-spectrum antibiotic, may be bactericidal or bacteriostatic, depending on its concentration at the site of infection and the susceptibility of the organism. Cycloserine works by blocking the formation of these peptidoglycans. By doing this the walls of the bacteria become weak and it results in the death of the bacteria.  Mechanism of action:-  Cycloserine is an analog of the amino acid D-alanine. It interferes with an early step in bacterial cell wall synthesis in the cytoplasm by competitive inhibition of two enzymes, L-alanine racemase, which forms D-alanine from L-alanine, and D-alanylalanine synthetase, which incorporates D-alanine into th...

BACITRACIN Uses, Side Effects, and More

 BACITRACIN BRAND NAME:- NEBASULF ,NEOSPORIN 400U/g powder. BACITRACIN is an antibiotic ointment that's used to help prevent skin infections in small cuts, scrapes, and burns. It's not meant to treat animal bites, serious burns, or deep puncture wounds - those might require medical attention. It's available over the counter (OTC) and as a less expensive, generic medication. PHARMACODYNAMIC:-  Bacitracin is a mixture of polypeptides that prevent the formation of the bacterial cell wall and oxidatively cleave DNA. It has a short duration of action as it must be given every 3 to 4 hours topically. Bacitracin is nephrotoxic when given intramuscularly and may lead to renal failure. MECHANISM OF ACTION:- Bacitracin interferes with the dephosphorylation of C55- isoprenyl pyrophosphate, and a related molecule known as bactoprenol pyrophosphate; both of these lipids function as membrane carrier molecules that transport the building-blocks of the peptidoglycan bacterial cell wall out...

BACLOFEN Uses, Side Effects, and More

 BACLOFEN BRAND NAME :- Lioresal ,liofen 10mg ,25mg tab . BACLOFEN is a commonly used muscle relaxer for the treatment of muscle spasms. It can be helpful for people with multiple sclerosis or spinal cord problems. Baclofen is available as oral tablets, granules, and liquid solutions. PHARMACODYNAMIC:-  Chemically, baclofen is a derivative of the neurotransmitter γ-aminobutyric acid (GABA). It is believed to work by activating (or agonizing) GABA receptors, specifically the GABAB receptors.[23] Its beneficial effects in spasticity result from its actions in the brain and spinal cord. PHARMACOKINETICS:-  The drug is rapidly absorbed after oral administration and is widely distributed throughout the body. Biotransformation is low: the drug is predominantly excreted unchanged by the kidneys.The half-life of baclofen is roughly 2–4 hours; it therefore needs to be administered frequently throughout the day to control spasticity appropriately. PHARMACODYNAMIC:-  Baclofen i...

BAL ( BRITISH ANTILEWISITE ) , DIMERCAPROL

 BAL ( BRITISH ANTILEWISITE ) , DIMERCAPROL  BRAND NAME:- BAL INJ mg/2ml ( in arachis oil) inj. DIMERCAPROL is a chelating agent used as an antidote to arsenic, gold, and mercury poisoning, as well as acute lead poisoning in combination with edetate calcium disodium. PHARMACODYNAMIC:- Due to its oily nature, dimercaprol is not absorbed orally and its administration requires a deep intra-muscular injection that is extremely painful and allergenic. It was found to mobilize and relocate lead to the brain, increasing its neurotoxic effects. Despite that fact that dimercaprol increases cadmium excretion, there is an associated increase in kidney cadmium concentration. Because of this, dimercaprol must be avoided in patients with cadmium toxicity.  MECHANISM OF ACTION:- The sulfhydryl groups of dimercaprol form complexes with certain heavy metals thus preventing or reversing the metallic binding of sulfhydryl-containing enzymes. The complex is excreted in the urine.  USED:...

BALSALAZIDE Uses, Side Effects, and More

 BALSALAZIDE BRAND NAME:- COLOREX 750mg cap and per 5ml syr. , INTAZIDE 750mg tab. BALSALAZIDE is 5-ASA linked to 4-aminobenzoyl- Beta - alanine as the carrier which, unlike sulfapyridine, is inert . The 5-ASA is released in the colon ,and the carrier is poorly absorbed. It can be used as a safer alternative to sulfasalazine. PHARMACODYNAMIC:-  Balsalazide is a prodrug that has little or no pharmacologic activity until it is enzymatically cleaved in the colon to produce mesalamine (5-aminosalicylic acid), an anti inflammatory drug indicated for the treatment of mildly to moderately active ulcerative colitis. Balsalazide disodium is delivered intact to the colon where it is cleaved by bacterial azoreduction to release equimolar quantities of mesalamine, which is the therapeutically active portion of the molecule, and the intert 4-aminobenzoyl-(beta)-alanine. As a result, the spectrum of pharmacologic activity of balsalazide is similar to that of mesalamine. MECHANISM OF ACTION:...

BAMBUTEROL Uses, Side Effects, and More

 BAMBUTEROL BRAND NAME:- BAMBUDIL 10mg ,20mg tabs ,5mg/5ml oral soln; BETADAY 10,20mg tabs. BAMBUTEROL is a bronchodilator. It works by relaxing the muscles in the airways and widens airways. This makes breathing easier. PHARMACODYNAMIC:-   Bambuterol is a long acting beta2-adrenoceptor agonist used in the treatment of asthma. It is a prodrug of terbutaline. Bambuterol causes smooth muscle relaxation, resulting in dilation of bronchial passages. MECHANISM OF ACTION:-  The pharmacologic effects of bambuterol are at least in part attributable to stimulation through beta-adrenergic receptors (beta 2 receptors) of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic AMP. Increased cyclic AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells. USED:-  used in the treatment of chronic obstructi...

BASILIXIMAB Uses, Side Effects, and More

 BASILIXIMAB BRAND NAME:- Simulect   BASILIXIMAB is another anti CD - 25 antibody with higher affinity for the IL-2 receptor, but shorter plasma t½ (1 week) . is a monoclonal antibody used to prevent rejection in kidney transplants. It is a chimeric mouse-human monoclonal antibody to the α chain (CD25) of the IL-2 receptor of T cells. It is used in combination with other medicines used to prevent organ rejection. PHARMACODYNAMIC:- Basiliximab functions as an IL-2 receptor antagonist. Specifically it inhibits IL-2-mediated activation of lymphocytes, a critical pathway in the cellular immune response involved in allograft rejection.  MECHANISM OF ACTION:-  Basiliximab competes with IL-2 to bind to the alpha chain subunit of the IL2 receptor on the surface of the activated T lymphocytes and thus prevents the receptor from signaling. This prevents T cells from replicating and also from activating B cells, which are responsible for the production of antibodies, which woul...
