BEVACIZUMAB Uses, Side Effects, and More

 BEVACIZUMAB


BRAND NAME:- AVASTIN 

Bevacizumab is a monoclonal anti-vascular endothelial growth factor antibody used in combination with antineoplastic agents for the treatment of many types of cancer. 

PHARMACODYNAMIC:-

Bevacizumab binds circulating vascular endothelial-derived growth factor (VEGF) and blocks it from binding to its associated receptors, effectively blunting downstream signaling. The effects of bevacizumab have been shown to re-establish normal vasculature at the tumor site resulting in increased nutrient and oxygen supply, while also improving the delivery of chemotherapeutic drugs to the target area.On the other hand, VEGF signaling is a vital component of several processes including angiogenesis, lymphangiogenesis, blood pressure regulation, wound healing, coagulation, and renal filtration. Although blocking VEGF may inhibit metastatic disease progression, it may also result in unintended effects due to the role of VEGF in several other physiologic processes. 


MECHANISM OF ACTION:-

Bevacizumab is a recombinant humanized monoclonal antibody that blocks angiogenesis by inhibiting vascular endothelial growth factor A (VEGF-A).[61] VEGF-A is a growth factor protein that stimulates angiogenesis in a variety of diseases, especially in cancer. By binding VEGF-A, bevacizumab should act outside the cell, but in some cases (cervical and breast cancer) it is taken up by cells through constitutive endocytosis.[62] Bevacizumab is the first available angiogenesis inhibitor in the United States. 


USED:-

used to treat a number of types of cancers and a specific eye disease.For cancer, it is given by slow injection into a vein (intravenous) and used for colon cancer, lung cancer, glioblastoma, and renal-cell carcinoma. In many of these diseases it is used as a first-line therapy. 


SIDE EFFECTS:-

Rise in BP , arterial thromboembolism leading to heart attack and stroke, vessel injury and haemorrhage heart failure,proteinuria , gastrointestinal perforation, and healing defects.


DOSE:-  BEVACIZUMAB is administered by i.v. infusion every 2-3 weeks.

BOTULINUM TOXIN Uses, Side Effects, and More

 BOTULINUM TOXIN ( A or B ) BRAND NAME:- BOTOX ,DYSPORT  BOTULINUM TOXIN  A and B are highly potent exotoxins produced by Clostridium botulinum that are responsible for ' botulism' ( a type of food poisoning). These neurotoxic proteins cause long- lasting loss of cholinergic transmission by interacting with axonal proteins involved in exocytotic release of Ach. Localized injection of minute quantity of botulinum toxin.  PHARMACODYNAMIC :- Botulinum toxin A inhibits the release of acetylcholine, relieving muscle contraction and spasm associated with many conditions, such as incontinence and dystonia. Cosmetically, botulinum toxin A paralyses muscles in the face to temporarily treat wrinkles. The maximum effects of muscle paralysis occur four to seven days after a dose.When injected at therapeutic doses, botulinum toxin A causes partial chemical denervation of muscle tissue, causing local reduction of muscle activity. Muscle atrophy may result, axonal sprouting may beg...

Clonazepam used, Side effects, Dose, & more

Clonazepam  Brand name:- Lonazepam , Clonapax , Rivotril 0.5, 1.0, 2.0 mg tab. Clonazepam 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:- The pharmacodynamic properties of clonazepam are common among benzodiazepines and include anticonvulsive, sedative, muscle relaxing and anxiolytic effects . Animal data and electroencephalographic investigations in man have shown that clonazepam rapidly suppresses many types of paroxysmal activity including the spike and wave discharge in absence seizures (petit mal), slow spike wave, generalized spike wave, spikes with temporal or other locations, as well as irregular spikes and waves Label . Moreover, the agent can also decrease the frequency, amplitude, duration, and spread of discharge in minor motor seizures Label . Generalized EEG abnormalities are more readily suppressed by clonazepam than are focal ...

CLOMIPHENE CITRATE Uses, Side Effects, and More

 CLOMIPHENE CITRATE BRAND NAME:- CLOMIPHENE, FERTOMED, CLOFERT, CLOME 25,50,100mg tab.  Clomiphene is a selective estrogen receptor modulator (SERM) which treats female infertility. It works by promoting the release of reproductive hormones. This helps stimulate the release of eggs from the ovary (ovulation). PHARMACODYANIMCS:- Clomifene (previously clomiphene) is an orally administered, non steroidal, ovulatory stimulant that acts as a selective estrogen receptor modulator (SERM). Clomifene can lead to multiple ovulation, and hence increase the risk of conceiving twins. In comparison to purified FSH, the rate of ovarian hyperstimulation syndrome is low. There may be an increased risk of ovarian cancer and weight gain. Clomifene is capable of interacting with estrogen-receptor-containing tissues, including the hypothalamus, pituitary, ovary, endometrium, vagina, and cervix. It may compete with estrogen for estrogen-receptor-binding sites and may delay replenishment of intracel...
