Sim, galantamina está disponível em comprimido de 4 mg

A galantamina, um inibidor da colinesterase usado no tratamento da doença de Alzheimer, está disponível em comprimidos de 4 mg. 1

Formulação e Dosagem Inicial

A galantamina é apresentada em comprimidos, e a dose inicial recomendada é de 4 mg duas vezes ao dia, administrada com as refeições da manhã e da noite 1. Esta formulação de 4 mg permite:

  • Titulação gradual: Após quatro semanas, a dose é aumentada para 8 mg duas vezes ao dia
  • Individualização posterior: Um aumento para 12 mg duas vezes ao dia pode ser considerado com base na avaliação do benefício clínico e tolerabilidade individual 1

Considerações Práticas

Administração

  • Os comprimidos devem ser tomados com as refeições para minimizar efeitos adversos gastrointestinais (náusea, vômito e diarreia) 1
  • A titulação gradual da dose é essencial para melhorar a tolerabilidade

Eficácia

Estudos demonstraram melhora dos desfechos cognitivos e funcionais, bem como dos sintomas comportamentais, com doses mais altas de galantamina em comparação com placebo 1

Advertência sobre Manipulação de Comprimidos

Embora o comprimido de 4 mg esteja disponível, evite partir comprimidos quando possível 2, 3. Se a divisão for inevitável, use um dispositivo de corte preciso, pois a divisão manual pode resultar em variação de conteúdo de até 21,3% 2, o que é particularmente problemático para medicamentos com janela terapêutica estreita.
