Cholera vaccine Uses, Side Effects, and More

 Cholera vaccine

Brand name:- Dukoral,ShanChol . 

Cholera Vaccine (Inactivated) is an inactivated vaccine (made from a dead bacteria). It helps develop immunity by forming antibodies, which are proteins that protect against infection caused by cholera bacteria. 

Pharmacodynamic:- 

It is a suspension of phenol/formation killed inaba and ogawa strains of V. Cholera,each ml containing 8× 10⁹ organisms in 5,10,30 ml vials.
 Immunity, sufficient to prevent clinical disease, is produced only in 50% of those innoculated , and lasts 6 months or so —sufficient to tide over an epidemic. Cholera innoculation during congregation (melas) has not reduced the incidence of the disease ( because it takes 2-3 weeks for immunity to develop): this practice has been discontinued. It also does not prevent carrier state. Transient local soreness,low grade fever,ashes and pains lasting 1-2days are common. Neurological complication are rare.

mechanics of action:-

It' s contains a live attenuated cholera bacterium that replicates in the gastrointestinal tract of the recipient. The exact mechanism of immunity has not been established; however, it is hypothesized that exposure to V. cholerae causes an elevation in baseline vibriocidal antibody titers (antibodies against V. cholerae), which results in immunity.

 used:-

Cholera Vaccine (Inactivated) is used to prevent Cholera.

 side effects:-

oral vaccine are generally safe.Mild abdominal pain or diarrhea may occur.They are safe in pregnancy and in those with poor immune function.

 Dose:-

0.5 ml s.c. or i.m. followed by 1ml 1-4 weeks later, or a single dose of 1 ml for mass innoculation .

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...
