Generic Kaletra Information

Introduction

Kaletra is a fixed‑dose combination tablet that contains the antiviral agents lopinavir and ritonavir. It belongs to the Human Immunodeficiency Virus (HIV) medication group and is used primarily to treat infection with HIV‑1. In Hong Kong, Kaletra is listed in the Department of Health’s formulary for patients whose treatment requires a protease‑inhibitor regimen. The combination has also been investigated for other viral illnesses, but its approved indication remains antiretroviral therapy (ART) for HIV‑1–infected adults.

What is Kaletra?

Kaletra is a co‑packaged, single‑tablet formulation that combines two protease inhibitors: lopinavir (the primary antiviral) and ritonavir (a pharmacokinetic enhancer that increases lopinavir plasma levels). The product was originally developed by AbbVie (formerly Abbott Laboratories) and received its first regulatory approval from the U.S. Food and Drug Administration (FDA) in 200.  

The tablet is marketed worldwide under the brand name Kaletra; generic equivalents containing the same active ingredients are also available from licensed manufacturers that meet Hong Kong’s pharmaceutical quality standards.

How Kaletra Works

Lopinavir inhibits the HIV‑1 protease enzyme, a key protein that cleaves newly synthesized viral polyproteins into functional components necessary for assembly of infectious virions. By blocking protease activity, lopinavir prevents maturation of the virus, leading to the production of non‑infectious viral particles.

Ritonavir, at sub‑therapeutic concentrations, is a potent inhibitor of the cytochrome P450 3A4 (CYP3A4) isozyme. This inhibition reduces the metabolic clearance of lopinavir, raising its plasma concentration and prolonging its half‑life from ~4 hours (when given alone) to ~8 hours when co‑administered. The result is a more sustained antiviral effect with once‑ or twice‑daily dosing. Therapeutic benefit typically manifests within 1–2 weeks of consistent dosing, reflecting a gradual reduction in plasma HIV RNA levels.

Conditions Treated with Kaletra

• HIV‑1 infection (adult patients) – Kaletra is approved for use in combination with other antiretrovirals as part of a complete ART regimen. In Hong Kong, the 2023 Department of Health guidelines list lopinavir/ritonavir as an alternative first‑line protease‑inhibitor option for patients who are intolerant of, or have contraindications to, integrase‑strand‑transfer inhibitors.
• HIV‑1 infection in treatment‑experienced adults – For individuals who have experienced virologic failure on other protease inhibitors, Kaletra may be re‑introduced as part of a salvage regimen, provided resistance testing confirms susceptibility.

Epidemiological context: As of 2022, Hong Kong reported approximately 9,400 cumulative cases of HIV infection, with an estimated 1,200 new diagnoses annually. Early and sustained viral suppression using ART—including Kaletra—has been shown to reduce morbidity, prolong life expectancy, and limit transmission risk.

Patient Populations Most Likely to Benefit

• Adults with newly diagnosed HIV‑1 who require a protease‑inhibitor backbone and have no contraindications to ritonavir (e.g., severe hepatic impairment).
• Patients who are pregnant or breastfeeding – Kaletra is classified as Pregnancy Category C in the United States. In Hong Kong, clinicians may prescribe it when the benefits outweigh potential risks, especially if other regimens are unsuitable.
• Individuals with comorbid infections such as hepatitis B or C, where the high barrier to resistance of protease inhibitors can be advantageous.
• Patients with a history of intolerance to other antiretrovirals (e.g., integrase inhibitors causing hypersensitivity).

Contraindications: Kaletra should not be used in patients with known hypersensitivity to lopinavir, ritonavir, or any tablet component. It is also contraindicated in severe hepatic failure (Child‑Pugh C) and in conjunction with drugs that are strong CYP3A4 inducers (e.g., rifampicin, carbamazepine) because therapeutic drug levels cannot be reliably maintained.

Risks, Side Effects, and Interactions

Common

• Diarrhoea – watery stools, usually mild to moderate, may improve with continued therapy.
• Nausea and vomiting – often transient during the first weeks of treatment.
• Taste disturbance – a metallic or bitter after‑taste is reported by up to 7 % of users.
• Hyperlipidaemia – increases in total cholesterol, LDL‑cholesterol and triglycerides have been observed; routine lipid monitoring is recommended.

Rare

• Hepatotoxicity – elevations in alanine transaminase (ALT) and aspartate transaminase (AST) values, rarely progressing to clinically significant hepatitis.
• Pancreatitis – especially in patients with a history of alcohol abuse or prior pancreatitis; immediate medical evaluation is required if severe abdominal pain develops.
• Insulin resistance and new‑onset diabetes – metabolic changes may precipitate hyperglycaemia in susceptible individuals.

Serious

• Severe allergic reactions – angio‑oedema, urticaria, or anaphylaxis; requires emergency treatment and permanent discontinuation.
• Cardiovascular events – accelerated atherosclerosis and myocardial infarction have been reported in long‑term use; patients with established cardiovascular disease need careful risk–benefit assessment.
• Transaminase‐related hepatic failure – rare but potentially life‑threatening.

Clinically Relevant Drug–Drug Interactions

• CYP3A4‑metabolised drugs – co‑administration with drugs such as simvastatin, atorvastatin, certain anti‑epileptics (e.g., carbamazepine), and some anti‑tuberculosis agents (rifampicin) can markedly increase or decrease drug exposure, leading to loss of efficacy or toxicity.
• Anticoagulants – warfarin clearance may be reduced, raising INR; closer monitoring is necessary.
• Concurrent antiretrovirals – careful dose adjustment is required when Kaletra is combined with other protease inhibitors or non‑nucleoside reverse transcriptase inhibitors (NNRTIs) to avoid overlapping toxicity.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare professional before initiating Kaletra.

Practical Use: Dosing, Missed Dose, Overdose

Standard dosing for adults (per current Hong Kong and WHO guidelines):

• Two tablets (each containing lopinavir 200 mg + ritonavir 50 mg) taken twice daily, 12 hours apart, with a full glass of water.

Missed dose:

• If a dose is forgotten and the scheduled dosing time is less than 2 hours away, take the missed tablet immediately and continue the regular dosing schedule. If more than 2 hours have elapsed, skip the missed dose and resume the next dose at the usual time. Do not double the dose to compensate.

Overdose:

• In the event of an accidental overdose, patients should seek urgent medical attention. Supportive care (e.g., monitoring of vital signs, gastrointestinal decontamination if clinically appropriate) is the primary management; there is no specific antidote.

Food and alcohol considerations:

• Kaletra can be taken with or without meals; however, a high‑fat meal may slightly increase lopinavir absorption, reducing variability.
• Excessive alcohol (more than 3 standard drinks per day) may aggravate hepatotoxicity and should be avoided.

Comorbidities:

• In patients with renal or hepatic impairment, dose adjustment is not routinely required for mild to moderate disease, but severe dysfunction warrants consultation with an HIV specialist and possible alternative therapy.

FAQ

• Is Kaletra available in both brand‑name and generic forms in Hong Kong?
  Yes, Kaletra is sold as a brand‑name product by AbbVie and also as a generic formulation produced by licensed manufacturers that meet Hong Kong’s pharmacopeial standards.

• What temperature range is optimal for storing Kaletra tablets?
  Kaletra should be kept at controlled room temperature (15 °C – 30 °C). Extreme heat or prolonged exposure to humidity can degrade the active ingredients.

• Does Kaletra contain any lactose or other common allergens?
  The tablet excipients include silicon dioxide, magnesium stearate, and a small amount of lactose monohydrate. Patients with severe lactose intolerance should consult a pharmacist before use.

• Can I travel internationally with Kaletra in my carry‑on luggage?
  Yes, Kaletra tablets are stable for short periods at ambient temperature and may be kept in carry‑on bags. Passengers should retain the original packaging and a copy of the prescription or a physician’s letter if requested by customs authorities.

• How does Kaletra’s formulation differ between the US and Asia?
  While the active ingredients are identical, some Asian‑market tablets use a film‑coated formulation to reduce moisture uptake, whereas the US version is a classic tablet. Both meet bioequivalence standards set by their respective regulatory agencies.

• Are there specific warnings for Kaletra use in Asian populations?
  Pharmacogenomic studies suggest a slightly higher prevalence of CYP3A5*3 allele among East Asian individuals, which may modestly affect ritonavir metabolism. Nonetheless, standard dosing is appropriate, and regular therapeutic monitoring remains essential.

• What is the shelf‑life of Kaletra after it is shipped from our pharmacy?
  Kaletra tablets retain full potency for 36 months when stored as directed. The expiry date is printed on each package, and the pharmacy includes a digital reminder of the date at dispatch.

• Can Kaletra be imported for personal use without a Hong Kong prescription?
  Personal import of prescription‑only medicines is permitted for a three‑month supply when the individual possesses a valid medical certificate from a recognised clinician. Our online pharmacy provides a copy of the import authorization upon request.

• Is Kaletra tested for compliance with the WHO International Pharmacopoeia?
  All generic batches supplied by our pharmacy undergo WHO‑certified quality control that includes assay of lopinavir and ritonavir content, impurity profiling, and dissolution testing.

• How does Kaletra compare to other protease inhibitors regarding resistance barriers?
  Lopinavir/ritonavir has a high genetic barrier to resistance because mutations that confer resistance typically reduce viral fitness. Clinical trials (e.g., ACTG 5257) showed lower rates of emergent resistance compared with some older protease inhibitors, making Kaletra a valuable option in treatment‑experienced patients.

• What are the storage requirements for Kaletra in high‑humidity climates such as Hong Kong?
  In humid environments, keep tablets in a dry, airtight container (e.g., a sealed plastic pouch) and avoid storage in bathrooms or kitchens where moisture levels exceed 60 %.

• Does Kaletra require a staggered start with other antiretrovirals?
  Typically, Kaletra is introduced simultaneously with other agents as part of a complete ART regimen. However, clinicians may stage introductions based on individual tolerability, especially when combining with integrase inhibitors that have overlapping metabolic pathways.
