Lonitab
Lonitab is oral minoxidil 5 mg tablets — ATP-sensitive potassium channel opener, potent direct arterial vasodilator. Original FDA approval 1979 as Loniten for severe resistant hypertension. HTN use requires concurrent beta-blocker (to block reflex tachycardia) and loop diuretic (to block fluid retention) — classical triple therapy. Low-dose oral minoxidil (1.25-5 mg) has emerged as widely-used off-label therapy for androgenetic alopecia. Hypertrichosis is universal at HTN doses, intended at hair-loss doses.

⚡ Quick Answer — What is Lonitab?
Lonitab is 5 mg oral minoxidil tablets from a WHO-GMP certified manufacturer — a potent direct arterial vasodilator (ATP-sensitive potassium channel opener). Original FDA approval (1979) was for severe resistant hypertension; oral minoxidil produces dramatic BP drops but requires concurrent beta-blocker (to prevent reflex tachycardia) and diuretic (to prevent sodium/fluid retention) — the classic “triple therapy” cocktail. More recently, low-dose oral minoxidil (1.25-5 mg) has emerged as widely-used off-label therapy for androgenetic alopecia (male and female pattern hair loss) — driven by dermatology-led case series and observational studies. Typical HTN dose: 5-40 mg once or twice daily (specialist supervision). Typical alopecia dose: 1.25-5 mg once daily (off-label). Contraindications: phaeochromocytoma, recent MI, pericardial effusion/tamponade, severe CHF without triple-therapy backbone.

What Is Lonitab?
Lonitab is 5 mg oral minoxidil tablets from a WHO-GMP certified manufacturer, supplied in 30-180 tablets. Minoxidil was introduced as Loniten by Upjohn in 1979 for severe resistant hypertension. The topical 2-5% solution (Rogaine / Regaine) launched separately for androgenetic alopecia after systemic minoxidil patients reliably grew unwanted body hair.
How Oral Minoxidil Works
Minoxidil is a prodrug activated in the liver to minoxidil sulfate. The active metabolite opens ATP-sensitive potassium (KATP) channels on arterial smooth muscle, hyperpolarising the cell membrane and producing powerful arterial vasodilation. No effect on venous tone. The vasodilation activates the sympathetic nervous system and renin-angiotensin-aldosterone system:
- Reflex tachycardia — heart rate rises substantially unless blocked by a beta-blocker
- Sodium and water retention — RAAS activation causes marked fluid retention unless blocked by a loop diuretic (thiazides are often insufficient)
- Pericardial effusion — a distinctive and serious complication (3% at high doses); mechanism unclear
- Hypertrichosis — hair growth on all body surfaces; basis for its off-label alopecia use
Approved and Off-Label Uses
- Severe resistant hypertension — particularly when ACEi/ARB + CCB + diuretic + spironolactone + beta-blocker have failed to control BP. Specialist-supervised.
- Hypertension in advanced CKD — effective at eGFR <30 where thiazides and RAAS blockers have been dropped.
- Androgenetic alopecia (off-label) — low-dose oral (1.25-5 mg) is rapidly gaining traction in dermatology, supported by large observational studies (ISHRS 2020, Rodrigues-Barata 2017). Faster and arguably more effective than topical minoxidil for some patients; lower adverse event rates than many assumed because hair-loss dosing is far below HTN dosing.
Dosage
Hypertension (specialist-led): start 2.5-5 mg once or twice daily; titrate to 10-40 mg/day. Must be combined with a beta-blocker and a loop diuretic — classical “triple therapy”. Without the concurrent agents, reflex tachycardia and fluid retention negate the BP benefit and precipitate heart failure.
Alopecia (off-label): 1.25-5 mg once daily. Dermatology-led. Typical starting dose 1.25-2.5 mg daily; uptitrate over weeks. At these doses, BP effects are usually mild (most patients do not need concurrent beta-blocker/diuretic). Monitor BP, HR, and lower-limb oedema at initiation.
Monitoring: BP (supine and standing), HR, weight (fluid retention), ECG (QT and evidence of pericardial effusion), echocardiography if any HF signs. Full blood count, U&E baseline and periodically.
Side Effects
- Hypertrichosis (universal at HTN doses; common at hair-loss doses) — excess hair on face, arms, back. Often disturbing to women at HTN doses; intended effect at hair-loss doses.
- Reflex tachycardia — prevented by concurrent beta-blocker
- Fluid retention, ankle oedema, weight gain — prevented by concurrent loop diuretic
- Pericardial effusion (3% at high doses; rare at low) — echocardiography at baseline and periodically; stop on any effusion
- Worsening of angina via reflex tachycardia
- ECG changes — T-wave flattening, rarely clinically significant
- Headache, flushing (first 2-4 weeks)
- Nausea
- Rarely breast tenderness
Contraindications
- Phaeochromocytoma (unopposed alpha-1 vasoconstriction can cause BP surge)
- Recent myocardial infarction
- Pericardial effusion or tamponade
- Severe uncontrolled heart failure without adequate diuretic cover
- Severe aortic stenosis or mitral stenosis
- Pregnancy (limited data; teratogenicity and fetal growth effects not fully characterised)
- Known hypersensitivity
Drug Interactions
- Beta-blockers — mandatory co-therapy at HTN doses (to block reflex tachycardia). Not required at hair-loss doses in most patients.
- Loop diuretics — mandatory co-therapy at HTN doses (thiazides are often insufficient).
- Guanethidine (rare) — severe orthostatic hypotension.
- PDE5 inhibitors (sildenafil, tadalafil) — additive hypotension.
- NSAIDs — blunt BP effect; raise AKI risk.
- Alcohol — additive hypotension.
Storage
Store Lonitab below 25°C. Keep out of reach of children.
Frequently Asked Questions
Is oral minoxidil safe for hair loss?
Low-dose oral minoxidil (1.25-5 mg daily) has a growing evidence base in dermatology. Side-effect rates at these doses are much lower than at HTN doses: hypertrichosis is expected (and often intended), transient ankle oedema is occasional, BP effects are usually mild. Pericardial effusion has not been reported at low doses. Starting dose typically 1.25 mg once daily; dermatology-led monitoring.
Why do I need a beta-blocker AND a diuretic with Lonitab?
At HTN doses, minoxidil’s arterial vasodilation is so powerful that the baroreceptor reflex drives heart rate up 20-40 bpm and the renin-angiotensin system retains litres of fluid — both negate the BP benefit and can precipitate heart failure. The beta-blocker (usually atenolol or metoprolol) blocks the tachycardia; a loop diuretic (furosemide) blocks the fluid retention. Without the cocktail, minoxidil is dangerous.
Can I take Lonitab in pregnancy?
Generally avoid. Pregnancy data are limited; case reports describe hypertrichosis in newborns exposed in utero. Use alternative antihypertensives (methyldopa, labetalol, nifedipine) in pregnancy.
Where can I buy Lonitab online?
You can buy Lonitab (minoxidil 5 mg, 30-180 tablets) from MedsBase with discreet packaging and worldwide shipping.
