Introduction to LOTREL
LOTREL is a combination medication consisting of amlodipine, a dihydropyridine calcium channel blocker (DHP CCB), and benazepril, an angiotensin-converting enzyme (ACE) inhibitor. It is primarily used for the treatment of hypertension in patients who are not adequately controlled on monotherapy with either agent[2].
Clinical Trials Experience
Patient Population and Trial Design
LOTREL has been extensively evaluated in clinical trials involving over 2,991 patients with hypertension. These trials included patients treated for at least 6 months, with over 400 patients treated for more than 1 year. The clinical trials were conducted under varying conditions, which is important to note when comparing adverse reaction rates across different studies[1][2].
Efficacy and Antihypertensive Effects
The antihypertensive effect of LOTREL is largely attained within 2 weeks of treatment initiation. Clinical trials using amlodipine doses of 2.5 to 10 mg and benazepril doses of 10 to 40 mg showed that the antihypertensive effects increased with increasing doses of both amlodipine and benazepril, particularly in nonblack patient groups[1][2].
Safety and Adverse Reactions
In a pooled analysis of 5 placebo-controlled trials, the reported side effects of LOTREL were generally mild and transient. Discontinuation of therapy due to side effects was required in approximately 4% of patients treated with LOTREL, compared to 3% of patients treated with placebo. The most common reasons for discontinuation were cough and edema, including angioedema. Notably, the addition of benazepril to a regimen of amlodipine substantially reduced the incidence of edema associated with amlodipine use[1][2].
Dosage and Administration
Initial Dosing and Titration
The recommended initial dose of LOTREL is amlodipine 2.5 mg/benazepril 10 mg orally once-daily. Therapy with LOTREL should only be initiated after a patient has either failed to achieve the desired antihypertensive effect with amlodipine or benazepril monotherapy or has demonstrated an inability to achieve adequate antihypertensive effect with amlodipine without developing edema. The dose may be titrated up to amlodipine 10 mg/benazepril 40 mg once-daily based on the patient’s clinical response[1][2].
Market Analysis
Current Market Position
LOTREL has been on the market since its initial U.S. approval in 1995. It is a well-established treatment option for hypertension, particularly for patients who do not respond adequately to monotherapy with either amlodipine or benazepril.
Competitive Landscape
The hypertension treatment market is highly competitive, with various monotherapies and combination therapies available. However, LOTREL's unique combination of a calcium channel blocker and an ACE inhibitor provides a distinct advantage in managing hypertension, especially in patients who experience edema with amlodipine monotherapy.
Market Projections
Given the ongoing need for effective hypertension management and the established efficacy and safety profile of LOTREL, it is likely that the drug will continue to maintain a significant market presence. The hypertension treatment market is expected to grow due to increasing prevalence of hypertension and the need for combination therapies that offer better blood pressure control.
Future Outlook and Trends
Emerging Trends in Hypertension Treatment
The hypertension treatment landscape is evolving with the introduction of new therapies and the increasing focus on personalized medicine. For instance, recent studies on drugs like zilebesiran, which demonstrated significant blood pressure reductions with encouraging safety profiles, may influence future treatment strategies[4].
Impact of Regulatory and Market Changes
Changes in regulatory landscapes and market conditions can affect the positioning of LOTREL. For example, shifts in healthcare policies and reimbursement strategies can influence the prescribing patterns of healthcare providers.

FAQs
What is LOTREL used for?
LOTREL is used for the treatment of hypertension in patients who are not adequately controlled on monotherapy with either amlodipine or benazepril[2].
What are the common side effects of LOTREL?
Common side effects include cough and edema, with the incidence of edema being substantially reduced when benazepril is added to a regimen of amlodipine[1][2].
How is LOTREL dosed?
The recommended initial dose is amlodipine 2.5 mg/benazepril 10 mg orally once-daily, with potential titration up to amlodipine 10 mg/benazepril 40 mg once-daily based on clinical response[1][2].
Is LOTREL effective in all patient groups?
LOTREL is effective in all patient groups, although the antihypertensive effect of benazepril may not provide additional benefit in African-American patients. However, all patient groups benefit from the reduction in amlodipine-induced edema[1][2].
What is the significance of LOTREL in the hypertension treatment market?
LOTREL is significant due to its unique combination of a calcium channel blocker and an ACE inhibitor, making it an effective option for managing hypertension, especially in patients who experience edema with amlodipine monotherapy.
