Influence of Food on the Bioavailability of Two Doses of Telmisartan/HCTZ Fixed-dose Combination in Japanese Healthy Male Volunteers

Influence of Food on the Bioavailability of Telmisartan 40 mg/HCTZ 12.5 mg Fixed-dose Combination and of Telmisartan 80 mg/HCTZ 12.5 mg Fixed-dose Combination in Japanese Healthy Male Volunteers (an Open-label, Randomised, Single-dose, Two-way Crossover Study)
