ACTONEL 5mg _ Tablets/Film-coated

What is ACTONEL 5mg _

ACTONEL 5mg is a film-coated oral tablet that contains risedronate sodium, a bisphosphonate used in the treatment and prevention of bone disorders. This medication is primarily prescribed to:

• Treat and prevent postmenopausal osteoporosis.
• Treat osteoporosis in men.
• Treat and prevent glucocorticoid-induced osteoporosis in individuals taking corticosteroids long-term.

Risedronate sodium works by altering the bone cycle, specifically inhibiting the cells that break down bone, known as osteoclasts. This helps to preserve bone density and reduce the risk of fractures, especially in the spine and hip. ACTONEL 5mg is typically taken once daily, and is available in 28-tablet packs for continuous use.

How to use ACTONEL 5mg _

To ensure maximum efficacy and minimize side effects, especially gastrointestinal irritation, ACTONEL 5mg should be taken with care:

• Timing: Take one tablet in the morning, at least 30 minutes before the first food, drink, or other medication.
• Administration: Swallow the tablet whole with a full glass (6–8 oz) of plain water. Do not chew or suck the tablet.
• Body position: Stay upright (sitting or standing) for at least 30 minutes after ingestion to prevent esophageal irritation.
• Avoid interacting substances: Do not take ACTONEL with mineral water, coffee, juice, antacids, or calcium-containing supplements.
• Missed dose: If you miss a dose, skip it and continue the next day as usual. Do not double up the dose.

Consistent adherence to the administration instructions improves outcomes and reduces the likelihood of adverse effects.

Mode of Action ACTONEL 5mg _

ACTONEL (risedronate sodium) is a bisphosphonate that works by:

• Targeting osteoclasts: These are the cells responsible for bone resorption. Risedronate binds to bone hydroxyapatite and specifically inhibits osteoclast activity.
• Reducing bone turnover: It decreases the rate of bone breakdown while allowing bone-forming cells (osteoblasts) to maintain or increase bone mass.
• Improving bone strength: Over time, this action helps maintain or increase bone mineral density and reduces the risk of fractures.

This pharmacological effect is crucial in osteoporosis, a condition where bone becomes weak and more likely to fracture due to increased resorption and reduced formation.

ACTONEL 5mg _ Interactions ACTONEL 5mg _

Drug interactions can alter the effectiveness or increase side effects of ACTONEL 5mg. Important interactions include:

• Calcium and mineral supplements: Calcium, magnesium, aluminum, and iron-containing products can interfere with ACTONEL absorption. Take these at least 30 minutes after ACTONEL.
• Antacids: These reduce stomach acid and can affect the tablet’s absorption. Space out administration accordingly.
• NSAIDs (e.g., ibuprofen, naproxen): Concurrent use may increase gastrointestinal side effects like irritation or ulcers.
• Food and beverages (other than water): Delay absorption; always take ACTONEL on an empty stomach with plain water.

Always inform your healthcare provider about all current medications and supplements to avoid harmful interactions.

Dosage of ACTONEL 5mg _

The usual dosage of ACTONEL 5mg depends on the condition being treated:

• Postmenopausal osteoporosis: 5mg once daily.
• Osteoporosis in men: 5mg once daily.
• Glucocorticoid-induced osteoporosis: 5mg once daily, particularly for patients on prolonged corticosteroid therapy.

For best results:

• Take the tablet at the same time each morning.
• Ensure adequate intake of calcium and vitamin D, unless contraindicated.
• Regular bone mineral density tests may be advised to assess effectiveness.

Never adjust your dosage without medical advice.

Possible side effects of ACTONEL 5mg _

Like all medications, ACTONEL 5mg may cause side effects. These can be categorized as common, less common, or rare:

• Common: Abdominal pain, nausea, indigestion, musculoskeletal pain, and headache.
• Less common: Diarrhea, constipation, dizziness, and rash.
• Serious (rare): Esophageal irritation or ulcers, jaw osteonecrosis (especially in cancer patients receiving IV bisphosphonates), and atypical femoral fractures with long-term use.

If you experience severe chest pain, difficulty swallowing, persistent bone pain, or unusual thigh/groin pain, contact your doctor immediately. These could be signs of serious side effects.

ACTONEL 5mg _ Contraindications ACTONEL 5mg _

ACTONEL should not be used in the following cases:

• Hypocalcemia: Low blood calcium levels must be corrected before initiating therapy.
• Esophageal disorders: Such as strictures or achalasia that delay esophageal emptying.
• Inability to remain upright: Patients who cannot sit or stand for at least 30 minutes post-dose.
• Severe renal impairment: Creatinine clearance <30 mL/min.
• Known allergy: Hypersensitivity to risedronate or any tablet components.

A thorough medical evaluation is essential to determine if ACTONEL is appropriate for you.
