'''藥物類別：[[:Category: 糖肽類 | 糖肽類抗生素]]'''

'''萬古霉素'''（English: [[Vancomycin]]）
==常見劑量==
萬古霉素通常有以下劑量：
*靜脈注射（IV）：500 毫克和 1 克小瓶
*口服：125 毫克和 250 毫克膠囊

==藥物商品名稱==
Vancocin

==藥物用途==
萬古霉素是一種糖肽抗生素，主要用於治療嚴重的細菌感染，特別是由耐甲氧西林金黃色葡萄球菌（MRSA）引起的感染，如：
*敗血症
*心內膜炎
*皮膚感染
*骨感染及
*由 Clostridium difficile 引起的偽膜性結腸炎等情況

==作用機制==
萬古霉素通過抑制細菌細胞壁的合成來發揮作用。它與細胞壁前體的D-丙氨酸-D-丙氨酸末端結合，阻止這些前體納入增長中的肽聚糖層，導致細菌細胞裂解。

==給藥途徑==
萬古霉素可通過以下途徑給藥：
*靜脈注射（IV）用於全身性感染
*口服用於特定的腸道感染，如 Clostridium difficile 結腸炎

==劑量==

[[Category: Drugs]][[Category: Glycopeptide]]

[[:Category: Antibiotics | '''Oral Antibiotics''']]

'''Drug class: [[:Category: Glycopeptide | Glycopeptide Antibiotics]]'''

'''Vancomycin (VANCOCIN)'''（中文：[[萬古霉素]]）
==Common Strengths==
Vancomycin is commonly available in the following strengths:
*Intravenous (IV): 500 mg and 1 g vials
*Oral: 125 mg and 250 mg capsules

==Drug Trade Names==
Vancocin

==Drug Usage==
Vancomycin is a glycopeptide antibiotic primarily used to treat severe bacterial infections, particularly those caused by methicillin-resistant Staphylococcus aureus (MRSA).

Vancomycin is indicated for conditions such as:
*septicemia
*endocarditis
*skin infections
*bone infections
*pseudomembranous colitis caused by Clostridium difficile.

==Mechanism of Action==
Vancomycin works by inhibiting bacterial wall synthesis. It binds to the D-alanyl-D-alanine terminus of cell wall precursors, preventing the incorporation of these precursors into the growing peptidoglycan layer and leading to bacterial cell lysis.

==Route of Administration==
Vancomycin can be administered:
*Intravenously (IV) for systemic infections
*Orally for specific gastrointestinal infections like C. difficile colitis

==Dosages==
*Adults: IV: 1 to 1.5 g every 12 hours (elderly >65 years 500 mg every 12 hours or 1 g once daily)
*Child: 15 mg/kg every 8 hours, max. 2 g daily
<Surgical prophylaxis> 1 g for 1 dose

==Side Effects==
{| class="wikitable"
!Frequency
!Adverse reactions
|-
| rowspan="3" | '''Common Side Effects
| Nausea
|-
| Abdominal pain
|-
| Flushing: Rapid intravenous infusion of vancomycin can lead to flushing, rash, and hypotension
|-
| rowspan="4" | '''Serious Side Effects
| Nephrotoxicity: Acute Kidney Injury especially in elderly patients or those with pre-existing kidney conditions. It manifests as increased serum creatinine levels and decreased urine output.
|-
| Ototoxicity: There is a risk of hearing loss which may present as tinnitus (ringing in the ears) or actual hearing impairment
|-
| Allergic reactions: Serious allergic reactions including symptoms such as hives, difficulty breathing, swelling of the face or throat, and severe skin reactions like Stevens-Johnson syndrome and toxic epidermal necrolysis.
|-
| Blood disorders: Neutropenia (low white blood cell count) and Thrombocytopenia (low platelet counts) which may increase the risk of infections and bleeding.
|}

==Pharmacokinetics==
*Absorption: Vancomycin has poor oral bioavailability (less than 10%), which limits its effectiveness when taken orally for systemic infections.
*Metabolism and Elimination: Vancomycin is not significantly metabolized; about 75-80% of the drug is excreted unchanged in the urine within the first 24 hours.
*Half-life: The elimination half-life in patients with normal renal function typically ranges from 4 to 11 hours, with an average of about 6 hours. In patients with renal impairment, this half-life can extend to several days, necessitating careful monitoring and dose adjustments
*Onset Time: The onset o action for intravenous vancomycin is rapid, with peak serum concentrations achieved immediately following the completion of the infusion. For oral vancomycin, the onset time is less clearly defined but is generally slower due to poor absorption.
*Duration of Action: The therapeutic effects of vancomycin can typically be observed within 48 to 72 hours after starting treatment. The duration of therapy depends on the type and severity of the infection; for instance, staphylococcal endocarditis may require prolonged treatment lasting three weeks or more.

==Drug Precautions==
'''Pregnancy

Use only if needed; potential risk should be weighed against benefits.

'''Breastfeeding

Present in milk; weigh potential risks against benefits.

'''Children and Elderly

Safety established in children. Elderly patients may require dose adjustments due to age-related renal function decline.

'''Drug Monitoring Items
*Due to its narrow therapeutic index, careful monitoring of vancomycin levels is crucial to ensure efficacy while minimizing toxicity, particularly nephrotoxicity.
*Serum creatinine levels

'''Drug Interactions
*Caution with nephrotoxic agents, such as
**Aminoglycosides (e.g. gentamicin, amikacin): Increased risk of kidney damage.
**Loop diuretics (e.g. furosemide): Increased risk of kidney damage.
**NSAIDs (e.g. ibuprofen): Potential for enhanced nephrotoxic effects.
**Anticoagulants (e.g. warfarin): There is a theoretical risk of increased bleeding.
**Anesthetic agents: May lead to cardiovascular and respiratory complications when used with vancomycin.

==FAQ==
'''What Should I Avoid while Taking?

Avoid other nephrotoxic medications unless advised by a healthcare provider.

|}

==Pharmacokinetics==
*Absorption: Peak serum concentrations are typically reached within 1 to 4 hours after oral administration.
*Elimination Half-Life: The elimination half-lives are about 10-11 hours for trimethoprim and 9-11 hours for sulfamethoxazole in healthy individuals. In cases of renal impairment, these half-lives can extend significantly, necessitating dosage adjustments.
*Both drugs are primarily eliminated via the kidneys.
*Onset Time: Typically within hours after administration.
*Duration of Action: Approximately 12 hours for the oral formulation.

==Drug Precautions==
'''Pregnancy

Contraindicated due to potential risks to the fetus.

'''Breastfeeding

Caution is advised; both components can pass into breast milk.

'''Children and Elderly

Use with caution; dosage adjustments may be necessary for pediatric patients under two months old and elderly patients with renal impairment.

'''Drug Monitoring Items

Monitor renal function (creatinine levels) and potassium levels, and potassium levels, especially in patients with pre-existing kidney issues.

'''Drug Interactions

Notable interactions include:
*Anticoagulants (e.g. Warfarin): Co-trimoxazole can enhance the anticoagulant effect of warfarin, increasing the risk of bleeding.
*Methotrexate: The concurrent use of co-trimoxazole with methotrexate lead to severe bone marrow suppression.
*Potassium-Sparing Diuretics and ACE Inhibitors: can increase the risk of hyperkalemia. Patients should be closely monitored for potassium levels, specially in those with renal impairment or other risk factors for cardiac issues.
Immunosuppressants (e.g. Tacrolimus, Ciclosporin): There is a potential for additive nephrotoxicity when co-trimoxazole is used with immunosuppressants like tacrolimus or ciclosporin. Frequent monitoring of drug levels and renal function is recommended if these drugs must be used together.
*Phenytoin: Co-trimoxazole can prolong the half-life of phenytoin, necessitating careful monitoring of serum levels to prevent toxicity.
*Diabetes Medications (e.g. Gliclazide, Glipizide): May increase the risk of hypoglycemia. Blood glucose levels should be monitored closely, and doses may need adjustment.
*Digoxin: Can increase digoxin exposure, which might lead to toxicity; therefore, monitoring digoxin levels is crucial when co-administering these drugs.
*Clozapine: Co-trimoxazole is contraindicated due to the risk of neutropenia.
*Amiodarone: There may be an increased risk of ventricular arrhythmias, particularly in patients with other risk factors for QT prolongation.

==FAQ==
'''How Should I Take the Tablet?

Take with a full glass of water, preferably on an empty stomach for better absorption.

'''What Should I Avoid while Taking?

Avoid Excessive sun exposure; use sunscreen as TMP-SMX can increase sensitivity to sunlight.

'''What Happens if I Miss a Dose?

Take it as soon as you remember unless it is close to the time for your next dose. Do not double up on doses.

'''Gentamicin (Garamycin)'''（中文：[[慶大霉素]]）
==Common Strengths==
*Injectable Solutions:
**40 mg/mL
**140 mg/mL
**80 mg/2 mL
**280 mg/2 mL

==Drug Trade Names==
Garamycin

==Drug Usage==
Gentamicin is indicated for the treatment of:
*Blood infections (septicemia)
*Meningitis
*Urinary tract infections (UTIs)
*Lung infections (e.g. pneumonia)
*Skin infections, including severe burns
*Bone and joint infections
*Endocarditis

==Mechanism of Action==
Gentamicin binds to the 30S ribosomal subunit of bacteria, inhibiting protein synthesis essential for bacterial growth. This binding interferes with the initiation of translation and elongation processes, ultimately leading to bacterial cell death.

==Route of Administration==
*Intravenous (IV)
*Intramuscular (IM)
*Topical (for skin and eye infections)
*Otic (ear drops)

==Dosages==
General Dosing Guidelines:
*Adults:
**Conventional dosing: 3-5 mg/kg/day IV/IM divided every 8 hours.
**Extended interval dosing: 4-7 mg/kg IV once daily.
*Renal Dosing Adjustments Based on eGFR:
**CrCl >90 mL/min: every 8 hours
**CrCl 60-90 mL/min or age ≥60: every 12 hours
**CrCl 25-60 mL/min: every 24 hours
**CrCl 10-25 mL/min: every 48 hours
**CrcL <10 mL/min: every 72 hours

|}

==Pharmacokinetics==
Absorption:
The aminoglycosides are not absorbed from the gut and must therefore be given by injection for systemic infections. The onset of action for gentamicin:
*After IV administration, gentamicin can begin exerting its effects within 30 minutes, making it suitable for urgent infections where immediate therapeutic action is needed.
Gentamicin has a half-life of approximately:
*IV Administration: ~75 minutes
*IM Administration: ~104 minutes
It is primarily eliminated by the kidneys, with renal clearance correlating closely with creatinine clearance. Monitoring serum levels is crucial to avoid toxicity, especially in patients with renal impairment.

==Drug Precautions==
'''Pregnancy

Gentamicin should only be used during pregnancy if the benefits outweigh the risks due to potential fetal harm, including ototoxicity and renal damage.

'''Breastfeeding

Gentamicin is excreted in breast milk but poses minimal risk to infants when used appropriately. Monitoring may be necessary if the infant has gastrointstinal issues.

'''Children and Elderly

Caution is advised in children, especially neonates and premature infants. Elderly patients may have increased risk due to potential renal impairment.

'''Drug Monitoring Items

Monitoring should include:
*Serum creatinine levels
*Auditory functions tests (hearing tests)
*Peak and trough gentamicin levels (target peak: 5-10 mg/L; trough: <2 mg/L for conventional dosing).

'''Drug Interactions

Gentamicin may interact with various medications, increasing the risk of nephrotoxicity or ototoxicity including:
*Nephrotoxic Agents: The risk of kidney damage is heightened when gentamicin is used alongside other nephrotoxic drugs. Such as:
**Vancomycin
**Amphotericin B
**Cisplatin
**Indomethacin
**Loop diuretics (e.g. furosemide, bumetanide) can also increase the risk of nephrotoxicity and ototoxicity.
*Nonsteroidal Anti-Inflammatory Drugs (NASIDs): Medications like ibuprofen and naproxen may reduce the renal clearance of gentamicin, potentially leading to elevated serum levels and increased toxicity.
*Neuromuscular Blocking Agents: Drugs such as pancuronium and atracurium can enhance neuromuscular blockade when used with gentamicin, increasing the risk of respiratory depression.

'''Drug class: [[:Category: Aminoglycoside | Aminoglycoside Antibiotics]]'''

'''Amikacin (AMIKIN)'''（中文：[[阿米卡星]]）
==Common Strengths==
*Injection: 250 mg/2 mL
*Injection: 500 mg/2 mL

==Drug Trade Names==
Amikin

==Drug Usage==
Amikacin is used for treating:
*Serious bacterial infections, particularly those resistant to other antibiotics.
*Infections caused by multidrug-resistant strains of bacteria, including Pseudomonas aeruginosa and Acinetobacter species.
*It may also be used for non-tubercular mycobacterial infections when first-line treatment fail.

==Mechanism of Action==
Amikacin binds to the 30S ribosomal subunit of bacteria, inhibiting protein synthesis. This interference leads to the productions of non-functional proteins, ultimately killing the bacteria.

==Route of Administration==
The aminoglycosides are not absorbed from the gut and must therefore be given by injection for systemic infections. Amikacin is administered via:
*Intravenous (IV)
*Intramuscular (IM)
*Inhalation (in specific formulations)

==Dosages==
General dosing for adults with normal renal function is:
*15 mg/kg/day, divided into doses every 8 to 12 hours.

==Side Effects==

| Nephrotoxicity (kidney damage)
|-
| Ototoxicity (hearing loss)
|-
| Neuromuscular blockade
|-
| Allergic reactions such as anaphylaxis
|}

==Pharmacokinetics==
Absorption:
*Amikacin is poorly absorbed when taken orally; thus, it must be administered parenterally (intravenously or intramuscularly).
*After intramuscular administration, peak serum concentrations are typically reached within 0.5 to 2 hours. For intravenous administration, peak levels can occur immediately after infusion.
Metabolism:
*Amikacin is not metabolized significantly in the body;
*About 98-99% of the administered dose is excreted unchanged in the urine.
*Only a small fraction (1-2%) is excreted via bile.
Elimination:
*The elimination half-life of amikacin ranges from 2 to 3 hours in individuals with normal renal function. However, this can increase significantly in patients with renal impairment.
*The drug is primarily cleared by the kidneys through glomerular filtration. In patients with reduced kidney function, dosing intervals must be adjusted to prevent accumulation and potential toxicity.

==Drug Precautions==
'''Pregnancy

Amikacin is generally not recommended during pregnancy due to potential risks of congenital deafness in infants.

'''Breastfeeding

Amikacin can pass into breast milk; consult a healthcare provider before breastfeeding.

'''Children and Elderly

Use with caution in children and elderly patients due to increased sensitivity to side effects.

'''Drug Monitoring Items

Regular monitoring of kidney function, hearing test, and serum drug levels is recommended during treatment.

'''Drug Interactions

Amikacin may interact with:
*Furosemide: This diuretic can enhance the nephrotoxic effects of amikacin, increasing the risk of kidney damage.
*Vancomycin: Concurrent use can lead to increased nephrotoxicity.
*Cisplatin and Amphotericin B: Both are nephrotoxic and should be avoided alongside amikacin.
*Neuromuscular blockers (e.g. succinylcholine): Amikacin can exacerbate neuromuscular blockade, leading to respiratory paralysis in susceptible individuals.

'''Azithromycin (ZITHROMAX)'''（中文：[[阿奇霉素]]）
==Common Strengths of Azithromycin==
*Tablet: 250 mg, 500 mg
*Powder for IV injection: 500 mg/vial
*Azithromycin eye-drops 1.5%

==Drug Trade Names==
Zithromax

==Drug Usage==
The macrolides have an antibacterial spectrum similar but not identical to penicillin; they are thus an alternative in penicillin-allergic patients.

Azithromycin is indicated for treating:
*Respiratory infections (e.g. pneumonia, bronchitis) - Ear infections
*Skin and soft-tissue infections
*Sexually transmitted infections (e.g. chlamydia)
*Sinusitis

==Mechanism of Action==
Azithromycin binds to the 50S ribosomal subunit of bacteria, inhibiting protein synthesis. This action prevents bacterial growth, making it primarily bacteriostatic, although it can exhibit bactericidal properties at higher concentrations.

==Route of Administration==
Azithromycin can be administered:
*Orally (tablets, capsules, liquid)
*Intravenously (in hospital settings)
*Topically (for eye infections)

==Dosages==
For adults, standard dosages are as follows:
*Normal individuals: 500 mg on day 1, followed by 250 mg daily for 4 days.
*Diabetic kidney disease: Generally, no renal dose adjustment is required as azithromycin is primarily eliminated via biliary excretion.

==Pharmacokinetics==
*Azithromycin has a long half-life of approximately 68 hours, allowing for once-daily dosing.
*It is well absorbed but works best on an empty stomach.
*Azithromycin is primarily eliminated through biliary excretion.
*The onset of action typically occurs within a few hours after oral administration.

==Drug Precautions==
'''Pregnancy

Advise use only if no suitable alternatives not available

'''Breastfeeding

Present in milk; use only if no suitable alternatives.

'''Children and Elderly

Dosages may vary; children as young as 6 months can be prescribed azithromycin for certain conditions. Elderly patients may be more susceptible to cardiac side effects.

'''Drug Monitoring Items

Monitor liver function tests and cardiac rhythm in susceptible populations.

'''Drug Interactions

Azithromycin interacts with numerous medications, including:
*Anticoagulants: There is an increased risk of bleeding when azithromycin is taken with apixaban, dabigatran, and warfarin.
*Statins: Co-administration with clarithromycin can lead to increased plasma concentrations of these statins, raising the risk of myopathy and rhabdomyolysis. It is advised to suspend these statins during clarithromycin treatment.
*Colchicine: Concomitant use can significantly increase colchicine levels, especially in patients with renal or hepatic impairment, leading to toxicity. This combination is contraindicated.
*Digoxin: There is a potential for increased digoxin levels when taken with azithromycin, which may lead to toxicity
*Antidepressants and antipsychotics: Medications such as citalopram and certain antipsychotics can also interact with azithromycin, increasing the risk of QT prolongation (a heart rhythm disorder) which may be serious or fatal.
*Nelfinavir: This HIV medication can increase azithromycin serum concentrations, necessitating careful monitoring for liver enzyme abnormalities and hearing impairment.

Disease Interactions:

Azithromycin has four notable disease interactions:
*QT Prolongation: Patients with existing heart rhythm issues are at increased risk for serious arrhythmias when taking azithromycin.
*Liver Disease: Azithromycin can exacerbate liver problems; monitoring liver function is recommended for patients with pre-existing liver conditions.
*Colitis: Antibiotic-associated colitis is a risk, particularly in patients with a history of gastrointestinal issues.
*Myasthenia Gravis: Azithromycin may worsen symptoms in patients with this neuromuscular disorder.

==FAQ==
'''How Should I Take the Tablet?

Take azithromycin with a full glass of water; it can be taken with or without food.

'''What Should I Avoid while Taking?

Avoid taking azithromycin with certain drugs that may increase the risk of serious side effects, such as pimozide and other QT-prolonging agents.

'''What Happens If I Miss a Dose?

If you miss a dose, take it as soon as you remember unless it is close to the time for your next dose. Do not double up on doses.
