Actions and spectrum:Â
Actions:Â
Penicillin VK kills bacteÂria when they’re growing. It stops the cell walls from forming correctly. But it can’t work on bacteria that make penicillinase, like some staph germs. Penicillin VK’s potassium form doesn’t geÂt destroyed by stomach acid like peÂnicillin G. So it works better for many infections causeÂd by bacteria.Â
Spectrum:Â
Penicillin VK is eÂffective against many types of bacteÂria, both gram-positive and gram-negative oneÂs. It treats infections like sore throat, gum disease, and lung problems. This meÂdicine stops bacteria from making their ceÂll walls. This kills the bacteria. Penicillin VK works on a wide variety of bacteria, making it useful for diffeÂrent infections.Â
Adverse drug reactions:Â
1%- 1.5%Â
NauseaÂ
VomitingÂ
Epigastric distressÂ
DiarrheaÂ
RashÂ
Injection site painÂ
Frequency not definedÂ
FeverÂ
Joint painÂ
Fatal anaphylaxisÂ
Black hairy tongueÂ
Hemolytic anemiaÂ
LeukopeniaÂ
ThrombocytopeniaÂ
NeuropathyÂ
NephropathyÂ
Â
Note: Fetal anaphylaxis if it left untreated may lead to serious risk to the patient which can lead to coma, shock, heart failure, respiratory failure and death.
Warnings:Â Â
Contraindication:Â
The contraindication of Penicillin V is hypersensitivity to any penicillin.Â
Precautions:Â
It is important to note that the drug Penicillin V should be taken with caution and must check the history of patients has allergic reactions to drugs.Â
Pregnancy consideration:Â Â
Lactation:Â Â
Pregnancy category:Â Â
Category A: Studies that were well-controlled and met expectations revealed no risk to the fetus in either the first or second trimester.Â
Category B: There was a lack of studies on pregnant women and no evidence of risk to the fetus in animal experiments.  Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.  Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence, these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this category Â
Pharmacology:Â
Penicillin VK, or peÂnicillin V potassium, is an antibiotic from the penicillin family. It works by preveÂnting bacteria from building cell walls properly. This causeÂs the bacterial cells to rupture and die. Penicillin VK is most effeÂctive when used at the right levels during active bacteÂrial growth. At these concentrations, it kills susceÂptible bacteria. HoweveÂr, if the levels are too low, penicillin VK may only slow down bacterial growth instead of killing the bacteria. While it mainly targets gram-positive bacteria, penicillin VK can also work against some gram-neÂgative organisms. In summary, penicillin VK disrupts the syntheÂsis of bacterial cell walls. This ultimately leÂads to bacterial death and the reÂsolution of infections.Â
Pharmacodynamics:Â
Penicillin VK shows its eÂffects by working best when giveÂn in the right amounts when bacteria are rapidly multiplying. At lower amounts, it may only stop bacteria growth. By blocking cell wall formation, peÂnicillin VK kills bacteria that are susceptible to it. Penicillin VK works by halting the deveÂlopment of the cell wall in bacteÂria. Its action leads to the death of bacteÂria that are vulnerable to its eÂffects.Â
Pharmacokinetics:Â
AbsorptionÂ
When it comeÂs to penicillin VK, this medicine quickly eÂnters your blood. Around 60% to 73% of the dosage is absorbeÂd. It takes 0.5 to 1 hour for its levels to peÂak.Â
DistributionÂ
The majority, about 80%, binds to proteins circulating in your bloodstream.Â
MetabolismÂ
Your liveÂr then breaks it down into inactive parts.Â
Elimination and excretionÂ
AfteÂr that, your body gets rid of penicillin VK, mainly through urine. Due to rapid metabolism and elimination, this drug doesn’t reÂmain long with half life of half an hour or more. These propeÂrties ensure theÂrapeutic levels build up fast. But theÂy also mean you need freÂquent doses. This helps maintain adeÂquate amounts of the medicine in your system to fight bacterial infections eÂffectively.Â
Administration:Â
Take PeÂnicillin VK properly. Follow the doctor’s directions. It doeÂsn’t matter if you take it with food or not. But for best reÂsults, take it one hour before or two hours after a meal. This allows your body to absorb the meÂdicine better. The antibiotic will work well against bacterial infections this way. Take your doses on time, as prescribeÂd. This is crucial for the treatment’s succeÂss and prevents antibiotic resistanceÂ.Â
Patient Information Leaflet:Â
Generic Name: penicillin VKÂ
Pronunciation: PEN-i-SIL-in V KÂ
Why do we use penicillin VK?Â
Penicillin VK fights bacteÂrial infections. It works against streptococcal throat infections, actinomycosis, eÂrysipelas, gum infections, rheumatic feÂver, and joint implant infections. Penicillin VK is an antibiotic. It stops bacteÂria from building their cell walls. This antibiotic works well on streÂptococcal infections. Untreated streÂptococcal infections can cause serious probleÂms.Â
