Introduction
Aqua Pen is a natural beta-lactam antibiotic and the precursor to the semi-synthetic penicillins. It is derived from Penicillium mold and is used to treat a variety of bacterial infections, especially those caused by gram-positive bacteria. Aqua Pen is also known as benzylpenicillin, phenoxymethylpenicillin, or simply penicillin.Uses
Aqua Pen is primarily used to treat or prevent bacterial infections caused by susceptible gram-positive organisms, including staphylococci and streptococci. It can also be used to treat some gram-negative infections, such as Neisseria meningitidis. Other uses include treatment of rheumatic fever and endocarditis caused by susceptible streptococci, as well as pneumococcal pneumonia and meningitis.Mechanism of Action
Aqua Pen interferes with bacterial cell wall synthesis by binding to and inhibiting penicillin-binding proteins (PBPs). This inhibition of PBPs prevents the formation of cross-linked peptidoglycan, which is essential for the structural integrity of the bacterial cell wall. By preventing the formation of cross-links, penicillin G disrupts the growth and division of bacteria, eventually leading to cell death.How long does it take to work?
The time it takes for penicillin G to take effect depends on the type of infection being treated and the severity of the infection. Generally, improvement should be seen within two to three days of starting treatment.Absorption
Aqua Pen is rapidly and almost completely absorbed from the gastrointestinal tract and peak concentrations are usually attained within one to four hours after administration.Route of Elimination
Aqua Pen is eliminated primarily in the urine by glomerular filtration and tubular secretion. It is also metabolized in the liver before being eliminated. The elimination half-life of penicillin G is approximately one hour.Dosage
The recommended dosage of penicillin G depends on the type and severity of the infection being treated. Aqua Pen is usually administered as an intravenous or intramuscular injection. For most infections, an adult dose of 500 mg to 1 g every four to six hours is recommended. In severe infections, a dose of up to 2 g every four to six hours may be used. The duration of treatment with penicillin G is usually 7 to 14 days.Administration
Aqua Pen is administered by intravenous or intramuscular injection. For intravenous use, the powder for injection should be reconstituted with at least 10 mL of bacteriostatic water or 0.9% sodium chloride for injection. For intramuscular use, the powder for injection should be reconstituted with at least 2 mL of bacteriostatic water or 0.9% sodium chloride for injection.Side Effects
Common side effects of penicillin G include nausea, vomiting, diarrhea, rash, fever, and headache. Rare but more serious side effects can include allergic reactions, anemia, thrombocytopenia, nephrotoxicity, and neurotoxicity.Toxicity
The symptoms of penicillin G overdose include nausea, vomiting, lethargy, confusion, and seizures. The overdose may also cause renal damage, hypotension, and anaphylaxis. Treatment of penicillin G overdose includes supportive care such as airway protection, pulmonary resuscitation, and fluids.Precautions
Before taking penicillin G, patients should inform their healthcare professionals if they have an allergy to penicillin or cephalosporins, have had a rash associated with a previous course of penicillin, or have kidney disease, liver disease, or anemia. Patients with any of these conditions may need a reduced dose or may need to be monitored closely.Interactions
Aqua Pen may interact with other drugs, such as anticoagulants, anticonvulsants, diuretics, methotrexate, probenecid, vaccines, and immunosuppressants. It is important to tell your healthcare professional about all medications you are taking before using penicillin G.Disease Interactions
Patients with liver or kidney disease, anemia, or any type of bleeding disorder should use penicillin G with caution, as these conditions may increase the risk of side effects or reduce the drug’s effectiveness. Patients with the following diseases should not use penicillin G: lupus, diabetes, and certain types of arthritis.Drug Interactions
Aqua Pen may interact with other drugs, including vaccines, anticoagulants, and diuretics. It is important to tell your healthcare professional about all medications you are taking before using penicillin G.Food Interactions
Aqua Pen should be taken with food to reduce the risk of stomach upset and nausea.Pregnancy Use
Aqua Pen should be used during pregnancy only if the potential benefits outweigh the potential risks to the fetus. It should be used with caution in the third trimester, as it may cause birth defects or other problems in the newborn.Lactation Use
Aqua Pen should be used with caution in breastfeeding women, as it can be excreted in breast milk and may cause side effects in the infant.Acute Overdose
Symptoms of an acute overdose of penicillin G include nausea, vomiting, confusion, seizures, and kidney or liver failure. Treatment includes supportive care such as airway protection, pulmonary resuscitation, and fluids.Contraindication
Aqua Pen is contraindicated in patients who are allergic to penicillin or other beta-lactams, have had a systemic allergic reaction to a cephalosporin, or have had a rash associated with a previous course of penicillin.Usage Directions
Aqua Pen is administered by intravenous or intramuscular injection. For intravenous use, the powder for injection should be reconstituted with at least 10 mL of bacteriostatic water or 0.9% sodium chloride for injection. For intramuscular use, the powder for injection should be reconstituted with at least 2 mL of bacteriostatic water or 0.9% sodium chloride for injection.Storage Conditions
Aqua Pen should be stored at room temperature, away from heat, light, and moisture. It should be kept in the original container and should be kept out of reach of children.Volume of Distribution
The volume of distribution of penicillin G is 0.2 L/kg.Half Life
The half-life of penicillin G is approximately one hour.Clearance
Aqua Pen is cleared primarily via the kidneys. Approximately 90% of an intravenous dose is excreted in the urine. The remaining 10% is metabolized by the liver before being eliminated.Here you find in details version of Aqua Pen
